You pick two digits 0 through 9 at random without replacement and write them in the order picked what is the probability that you have written the first two digits of your phone number assume there are no repeats of digits in your phone number give your answer as a fraction

Answers

Alright, so let's assume your phone number has no repeated digits. The first task is to select the first digit of the two-digit number. Since phone numbers don't start with zero, you have 9 choices (1 through 9).

The next task is to select the second digit. Because we've already used one digit, and we're assuming there are no repeats in the phone number, we have 9 choices left (0 and the 8 digits that were not selected first).

That gives us a total of 9 * 9 = 81 possible two-digit numbers.

Now, your phone number has a specific first two digits, right? There's only one such combination that matches your phone number.

So the probability that the two-digit number you've selected matches the first two digits of your phone number is 1 in 81, or 1/81.

Think of it this way, my friend: Imagine you have a bag with 81 marbles, each marble has a unique two-digit number on it. You close your eyes and reach into the bag to pick a marble. The chance that you'll pick out the marble with your phone number's first two digits is just like finding one special marble in a bag of 81. It's quite the quest, isn't it? But that's what makes the game of probability so interesting!

22.12 x 0.6 =

Answers

The product of 22.12 and 0.6 is indeed 13.272.

To compute the product of 22.12 and 0.6, we can perform the multiplication using the standard algorithm for decimal multiplication.

Multiply the decimal part (the digits after the decimal point) first.

0.12 x 0.6 = 0.072 (Multiply 12 by 6, which gives 72, and then move the decimal point two places to the left.)

Multiply the whole numbers.

22 x 0.6 = 13.2 (Multiply 22 by 6, which gives 132, and then move the decimal point one place to the left.)

Add the results from Step 1 and Step 2.

0.072 + 13.2 = 13.272

Therefore, when multiplying 22.12 by 0.6, the result is 13.272.

To verify the calculation, we can check by using estimation. 22.12 is approximately 22 and 0.6 is approximately 0.6. Multiplying 22 by 0.6 gives 13.2, which is close to our calculated result of 13.272. This further confirms that our multiplication is correct.

Hence, the product of 22.12 and 0.6 is indeed 13.272.

{4x + y = 7
{2y + 3= 3x - 16

A. (1,3)
B. (3,-5)
C. (7,-1)
D. No solution

Answers

The solution for the system of equations is (x, y) = B. (3, -5).

The correct option is B. (3, -5).

To find the solution for the system of equations:

{4x + y = 7

{2y + 3 = 3x - 16

We can solve it using the method of substitution or elimination. Let's use the method of elimination:

First, let's multiply the second equation by 2 to eliminate the variable y:

2(2y + 3) = 2(3x - 16)

4y + 6 = 6x - 32

Rearranging this equation, we get:

6x - 4y = 38 ----(1)

Now we have the system of equations:

4x + y = 7 ----(2)

6x - 4y = 38 ----(1)

Next, let's multiply equation (2) by 4 to eliminate the variable y:

4(4x + y) = 4(7)

16x + 4y = 28

Now we have the system of equations:

16x + 4y = 28 ----(3)

6x - 4y = 38 ----(1)

Adding equations (3) and (1) eliminates the variable y:

(16x + 4y) + (6x - 4y) = 28 + 38

22x = 66

x = 66/22

x = 3

Substituting the value of x into equation (2), we can solve for y:

4(3) + y = 7

12 + y = 7

y = 7 - 12

y = -5

-4x^2 + 2x - 5(1+x) which expression is equivalent to the given expression

Answers

The given expression -4x^2 + 2x - 5(1+x) is equivalent to -4x^2 - 3x - 5, not -5 - 5x.

To simplify the expression -4x^2 + 2x - 5(1+x), we can distribute the -5 to the terms inside the parentheses:

-4x^2 + 2x - 5(1+x) = -4x^2 + 2x - 5 - 5x

Next, we can combine like terms:

-4x^2 + 2x - 5 - 5x = -4x^2 + (2x - 5x) - 5

Simplifying further, we have:

-4x^2 + (2x - 5x) - 5 = -4x^2 - 3x - 5

Therefore, the expression -4x^2 + 2x - 5(1+x) is equivalent to -4x^2 - 3x - 5.

It's important to note that when we distribute the -5 to the terms inside the parentheses, we multiply each term by -5. So, the expression becomes -5(1) - 5(x). However, -5(1) simplifies to -5, and -5(x) simplifies to -5x. Hence, the expression simplifies to -5 - 5x.

Answers

Megan is wrong because the square root of a number can be either smaller or larger, depending on whether the number is less than or greater than 1.

Megan's statement that "when you square root a number, the answer is always smaller" is incorrect.

In fact, the square root of a number can be either smaller or larger than the original number, depending on the value of the number.

To demonstrate that Megan is wrong, let's consider a few examples:

Square root of 4:

The square root of 4 is 2.

In this case, the square root is smaller than the original number.

Square root of 1:

The square root of 1 is also 1.

Here, the square root is equal to the original number.

Square root of 9:

The square root of 9 is 3.

In this case, the square root is larger than the original number.

Square root of 16:

The square root of 16 is 4.

Again, the square root is larger than the original number.

From these examples, we can see that the square root of a number can be smaller, equal to, or larger than the original number.

It depends on the specific value of the number.

Megan's statement oversimplifies the relationship between a number and its square root.

In general, the square root of a number is a value that, when multiplied by itself, gives the original number.

It is not always smaller but rather a value that satisfies the mathematical relationship.

What is the area of a right triangle with a height of six and one fourth yards and a base of 22 yards?

34 yds2
sixty eight and three fourths yds2
132 yds2
one hundred thirty seven and one half yds2

Answers

Answer:

68.75 square yards (rounded to the nearest hundredth).

Step-by-step explanation:

To find the area of a right triangle, we can use the formula:

Area = (1/2) * base * height

Given the height of 6 and one fourth yards (6 1/4) and a base of 22 yards, we can calculate the area as follows:

Area = (1/2) * 22 * (6 1/4)

To simplify the calculation, we can convert the mixed fraction 6 1/4 to an improper fraction:

6 1/4 = (4 * 6 + 1) / 4 = 25 / 4

Now we can substitute the values into the area formula:

Area = (1/2) * 22 * (25/4)

Next, we can simplify the expression by multiplying the numbers:

Area = (11/1) * (25/4)

Multiplying the numerators and denominators:

Area = (11 * 25) / (1 * 4)

= 275 / 4

To convert the fraction to a mixed number, we can divide the numerator by the denominator:

275 ÷ 4 = 68 remainder 3

Therefore, the area of the right triangle is:

Area = 68 3/4 square yards or 68.75 square yards (rounded to the nearest hundredth).

Among the options provided, the closest match is "sixty-eight and three fourths yds2".

The degree is 4 the leading coefficient is even/positive.  There are 3 distinct real 0's and 3 relative extreme values

Explanation:

4th degree.   Degree is the highest exponent.  The number of 0's (times it hits the curve)tells you the degree.  The curve goes through the x 2 times, which means 2 x's. Then it bounces off x 1 time which means there are 2 x's there too but because this one bounces off it means it's not a distint solution it's a multiplicity ex (x-3)².  So that accounts for 4 solutions

Even/positive coefficient.  That's the first number in the equation.  Because it's facing up it's a positive but all the ends are both facing up so that tells you it's even.  Think of a parabola that is an even function, this follows those rules too.

3 distinct zeroes.    This is explained in 4th degree.   Zeroes are solutions, when it hits x axis.  Goes through x 2 times and bounces once.  So there are 3 distinct zeroes

3 relative extreme values. This is how many "mini" max and mins you have.

The chi-square test of independence is a useful statistical method that can be used to test the null hypothesis that there is no association between two categorical variables. When the assumptions of the test are satisfied, this hypothesis can be tested using the chi-square statistic. The following problem can be solved using the chi-square test of independence:

Is gender associated with a person's environmental awareness? Two hundred randomly selected individuals were surveyed about their environmental awareness. Participants were asked about recycling, use of aerosol sprays, and various other environmental concerns.

Those with scores of 8 to 10 were considered to be very environmentally aware, scores of 4 to 6 moderately aware, and 3 or less not aware.

The results are shown in the following table: Very environmentally aware Moderately environmentally aware Not environmentally aware Male 302145 Female 423428 We will use a chi-square test of independence to test the null hypothesis that gender is not associated with one's environmental awareness.

We begin by specifying the null and alternative hypotheses: H0: Gender and environmental awareness are independent.

Ha: Gender and environmental awareness are dependent. We choose a significance level of α = 0.05. We can now proceed with the chi-square test of independence.

First, we will calculate the expected frequencies. The expected frequency for each cell can be found by multiplying the row total by the column total and then dividing by the sample size.

The expected frequencies are shown in the following table: Very environmentally aware Moderately environmentally aware not environmentally aware Male 22.5716.6176.81 Female 49.424.826.19 Next, we calculate the chi-square statistic using the formula: X2 = ∑(O - E)2/E where O is the observed frequency and E is the expected frequency.

The chi-square statistic is 18.66. We now need to find the degrees of freedom.

The degrees of freedom for a chi-square test of independence are given by df = (r - 1)(c - 1) where r is the number of rows and c is the number of columns. In this case, there are 2 rows and 3 columns, so df = (2 - 1)(3 - 1) = 2.

We can now use a chi-square distribution table to find the critical value of the chi-square distribution with 2 degrees of freedom and a significance level of 0.05.

The critical value is 5.99. Since the calculated value of the chi-square statistic (18.66) is greater than the critical value (5.99), we reject the null hypothesis.

We have sufficient evidence to conclude that gender and environmental awareness are dependent. Therefore, we can conclude that gender is associated with a person's environmental awareness.

Kate is firing off her homemade rockets for a project in physics class. The
maximum height of any of her rockets can be represented by the equation
h = 40t-16t², where h is the height (in feet) of the rocket after t seconds.

Find the domain and range

Answers

The domain of the height function is [0, 2.5]

The range of the height function is [0, 25]

How to find the domain and range?

We know that the height is given by the quadratic function:

h(t) = 40t - 16t²

First, the domain. This is the set of possible values of t.

We know that we start at t = 0.

The final value of the domain is t such that the rocket returns to the ground, that is when h = 0.

We can rewrite the function as:

h(t) = 40t - 16t² = t*(40 - 16t)

It is zero when t = 0 (we already know) and when 40 - 16t = 0

Solving the second one we get:

40 - 16t = 0

40 = 16t

40/16 = t

2.5 = t

Then the domain is [0, 2.5]

For the range we need to find the maximum height, we know that the minimum height is h = 0.

The maximum one is when t = (2.5 + 0)/2 = 1.25

Evaluating there we get:

h = 40*1.25 - 16*(1.25)²

h =  25

Then the range is [0, 25]

What is the value of the missing sides?

To solve the missing side, we have to use the sine angle formula.

The law of sine or the sine law states that the ratio of the side length of a triangle to the sine of the opposite angle, which is the same for all three sides.

The formula is given as;

a / sin A = b / sin B

A = 38° 18' = 38.03°

Substituting the values into the formula

300 / sin 38.03 = 150 / sin B

sin B = 150 * sin 38.03 / 300

sin B = 0.3080

B = sin⁻¹(0.3080)

B = 17.94°

From the sum of angles in a triangle;

A + B + C = 180°

38.03 + 17.94 + C = 180

C = 124.03°

Using cosine rule;

c² = a² + b² - 2(a)(b)cos C

c² = 300² + 150² - 2(300)(150)cos 124.03°

c² = 162866.422

c = √162866.422

c = 403.57m

PART A

A manufacturer is designing a flashlight. For the flashlight to emit a focused beam, the bulb needs to be on the central axis of the parabolic reflector, 3 centimeters from the vertex. Write an equation that models the parabola formed when a cross section is taken through the reflector’s central axis. Assume that the vertex of the parabola is at the origin in the xy coordinate plane and the parabola can open in any direction.

answer: y= 1/12(x-0)^2+0

Find the equation of the directrix of the parabola found in part A.

Answers

The equation of the directrix of the parabola found in part A is [tex]x^2 = -2cy + c^2.[/tex]

The equation of the parabola formed when a cross section is taken through the reflector's central axis is

[tex]y = (1/12)(x - 0)^2 + 0.[/tex]

In this equation, the vertex is at the origin (0, 0) and the coefficient 1/12 determines the shape of the parabola.

The equation implies that the parabola opens upward because the coefficient of [tex]x^2[/tex] is positive.

To find the equation of the directrix, we can use the distance formula. The directrix is a horizontal line that is equidistant from the vertex as any point on the parabola.

Since the parabola is symmetric with respect to the y-axis, the directrix will also be symmetric with respect to the y-axis.

Let's assume that the directrix is a horizontal line with the equation y = c, where c is a constant.

To find the value of c, we need to consider a point (x, y) on the parabola. The distance from the point (x, y) to the directrix y = c should be equal to the distance from the point (x, y) to the vertex (0, 0).

Using the distance formula, the distance from (x, y) to the directrix y = c is given by |y - c|, and the distance from (x, y) to the vertex (0, 0) is given by [tex]\sqrt{(x^2 + y^2)}[/tex]

Setting these distances equal, we have:

[tex]|y - c| = \sqrt{(x^2 + y^2)}[/tex]

Squaring both sides of the equation, we get:

[tex](y - c)^2 = x^2 + y^2[/tex]

Expanding and simplifying the equation, we have:

[tex]y^2 - 2cy + c^2 = x^2 + y^2[/tex]

Simplifying further, we obtain:

[tex]-2cy + c^2 = x^2[/tex]

Rearranging the terms, we get:

[tex]x^2 = -2cy + c^2[/tex]

This equation represents the equation of the directrix of the parabola formed by the reflector.

A state offers specialty license plates that contain 3 letters followed by 2 numbers. License plates are assigned randomly. All license plates are equally likely. Find the number of possible license plates that can be issued using this system.

Answers

There are 17,576,000 possible license plates that can be issued using this system.

To calculate the number of possible license plates that can be issued using this system, we need to determine the number of options for each character in the license plate.

For the first character, there are 26 letters in the English alphabet. Therefore, we have 26 options for the first character.

Similarly, for the second and third characters, we also have 26 options each.

For the fourth character, there are 10 possible numbers (0-9).

And for the fifth character, we again have 10 possible numbers.

To find the total number of possible license plates, we multiply the number of options for each character together:

Number of possible license plates = Number of options for the first character × Number of options for the second character × Number of options for the third character × Number of options for the fourth character × Number of options for the fifth character

Number of possible license plates = 26 × 26 × 26 × 10 × 10

Calculating this expression gives us:

Number of possible license plates = 17,576,000

Therefore, there are 17,576,000 possible license plates that can be issued using this system.

Un automóvil de 800 kg se desplaza a 50km/h cuál será su energía cinética.

Answers

The kinetic energy of this car is equal to 77160.49 Joules.

How to calculate the kinetic energy of this car?

In Mathematics, the kinetic energy of a physical object can be calculated by using the following equation (formula):

K.E = 1/2 × mv²

Where:

K.E represent the kinetic energy.m represent the mass.v represent the speed or velocity.

Note: 50 km/h to m/s = 50 × 1000/3600 = 13.89 m/s

By substituting the given parameters into the formula for the kinetic energy of a physical object, we have the following:

Kinetic energy, K.E = 1/2 × 800 × 13.89²

Kinetic energy, K.E = 400 × 192.90

The statement about the points (0, 3), (2, 8), (8, 2), and (0, 1) that is true is All but one of the points are in Quadrant I. Option C

How to determine the statement

The first quadrant, positioned at the upper-right area of the Cartesian plane, involves coordinates that have favorable values for both x and y.

The coordinates (0,3), (2,8), and (0,1) all fall under quadrant I since their x and y values are positive.

The point located in Quadrant IV can be identified as (8, 2) due to its positive x-coordinate and negative y-coordinate.

Hence, it can be said with precision that Quadrant I contains all but one point.
