A downtown parking lot charges $5 per hour for the first 2 hours, then $2.50 per hour after that. What equation describes the total cost y as a function of the hours x?

Answers

The equation y = 5x for x ≤ 2 and y = 10 + 2.5(x-2) for x ≥ 2.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

In other words, an equation is a set of variables that are constrained through a situation or case.

Given that,

First, the two-hour rate of charge is $5 per hour

y = 5x for x ≤ 2

Over the 2 hours, the rate of charge is $2.5 per hour

y = 10 + 2.5(x-2) for x ≥ 2.

Hence "The equation y = 5x for x ≤ 2 and y = 10 + 2.5(x-2) for x ≥ 2".

75% of the Pottery Club members paid their $5.00 dues. If there are 48 members, how many members paid?

Answers

Answer:

36 members paid the total money that would be made would be $180

Step-by-step explanation:

48*75%=36

36*5=180

If 75% of the Pottery Club members paid their dues, then 75/100 = 3/4 of the members paid.
If there are 48 members in the Pottery Club, then to find out how many members paid, we can multiply the total number of members by the proportion that paid, which is:
48 x 3/4 = 36 members paid.
So 36 members paid the $5.00 dues.

We choose a number from the set 10, 11,12,...,99) uniformly at random. (a) Let X be the first digit and Y the second digit of the chosen number. Show that X and Y are independent random variables. (b) Let X be the first digit of the chosen number and Z be the sum of the two digits. Show that X and Z are not independent

Answers

X and Z are not independent random variable as P(X = x and Z = z) and  P(X = x) * P(Z = z) are not equal for most values of x and z by using their joint probability

To prove that two random variables are independent,  to show that their joint probability distribution is equal to the product of their individual probability distributions. Start with part (a) and then move on to part (b).

(a) Let X be the first digit and Y be the second digit of the chosen number from the set {10, 11, 12, ..., 99}.

Step 1: Calculate the probabilities of X and Y individually.

To find the probability of X taking any particular value,

there are 9 numbers (10 to 99) that start with each digit from 1 to 9. Since we choose a number uniformly at random, each first digit has an equal chance of being selected.

The probability of X taking any value x (where x is a digit from 1 to 9) is given by:

P(X = x) = (number of numbers starting with digit x) / (total numbers)

= 9 / 90

= 1 / 10

Similarly, for Y, since there are 10 digits (0 to 9) and  choose the second digit uniformly at random, the probability of Y taking any value y is:

P(Y = y) = (number of numbers with digit y as the second digit) / (total numbers)

= 10 / 90

= 1 / 9

Step 2: Calculate the joint probability P(X, Y).

The joint probability is the probability that X takes a particular value x and Y takes a particular value y simultaneously.

P(X = x and Y = y) = (number of numbers with digit x as the first digit and digit y as the second digit) / (total numbers)

= 1 / 90

Step 3: Check if X and Y are independent.

Two random variables X and Y are independent if and only if their joint probability equals the product of their individual probabilities.

P(X = x and Y = y) = P(X = x) * P(Y = y)

1 / 90 = (1 / 10) * (1 / 9)

Since the equation holds for all values of x and y,  conclude that X and Y are independent random variables.

(b) Let X be the first digit of the chosen number and Z be the sum of the two digits.

Step 1: Calculate the probabilities of X and Z individually.

Calculated the probability distribution for X in part (a), which is P(X = x) = 1 / 10 for x = 1 to 9.

To  calculate the probability distribution for Z, the sum of the two digits:

For Z = 0: There is only one number, 10, with a sum of digits equal to 0.

P(Z = 0) = 1 / 90

For Z = 1: There are two numbers, 10 and 01, with a sum of digits equal to 1.

P(Z = 1) = 2 / 90

= 1 / 45

For Z = 2: There are three numbers, 11, 20, and 02, with a sum of digits equal to 2.

P(Z = 2) = 3 / 90

= 1 / 30

For Z = 3: There are four numbers, 12, 21, 03, and 30, with a sum of digits equal to 3.

P(Z = 3) = 4 / 90

= 2 / 45

For Z = 4: There are five numbers, 13, 31, 04, 40, and 22, with a sum of digits equal to 4.

P(Z = 4) = 5 / 90

= 1 / 18

For Z = 5: There are four numbers, 14, 41, 23, and 32, with a sum of digits equal to 5.

P(Z = 5) = 4 / 90

= 2 / 45

For Z = 6: There are three numbers, 15, 51, and 24, with a sum of digits equal to 6.

P(Z = 6) = 3 / 90

= 1 / 30

For Z = 7: There are two numbers, 25 and 52, with a sum of digits equal to 7.

P(Z = 7) = 2 / 90

= 1 / 45

For Z = 8: There are two numbers, 26 and 62, with a sum of digits equal to 8.

P(Z = 8) = 2 / 90

= 1 / 45

For Z = 9: There is only one number, 36, with a sum of digits equal to 9.

P(Z = 9) = 1 / 90

Step 2: Calculate the joint probability P(X, Z).

The joint probability is the probability that X takes a particular value x and Z takes a particular value z simultaneously.

Formula:

P(X = x and Z = z) = (number of numbers with digit x as the first digit and the sum of digits equal to z) / (total numbers)

Check the case where X = 1 and Z = 2 as an example:

Numbers with digit 1 as the first digit and a sum of digits equal to 2: 12 and 21 (two numbers)

P(X = 1 and Z = 2) = 2 / 90

= 1 / 45

Step 3: Check if X and Z are independent.

To determine if X and Z are independent, we need to compare their joint probability to the product of their individual probabilities for all values of x and z.

However, if compare the joint probabilities P(X = x and Z = z) to P(X = x) * P(Z = z), find that they are not equal for most values of x and z.

Therefore, conclude that X and Z are not independent random variables.

as P(X = x and Z = z) and  P(X = x) * P(Z = z) are not equal for most values of x and z.

He played last week and scored a 4 on 7 holes. Zaire will get an extra bonus if he has a
total of 60 points from scores of 4 after he finishes today. On how many holes does he
need to score a 4 today?


Please help!!!

Answers

Zaire has a total of 7 holes * 4 points/hole = 28 points from scores of 4 from last week.To reach 60 points, he needs to score 4 on 60 - 28 = 32 more holes today. So, Zaire needs to score a 4 on 32 holes today.

How many holes does Zaire need to score a 4 on today in order to reach a total of 60 points?To calculate the number of holes on which Zaire needs to score a 4 today, we can use the following equation:X = (60 - (4 x 7)) / 4Where X is the number of holes on which Zaire needs to score a 4 today, 60 is the total number of points he needs to reach to get the bonus, 4 is the number of points he gets for each hole on which he scores a 4, and 7 is the number of holes on which he scored a 4 last week.Here's the step-by-step explanation:Subtract the total number of points he earned last week (4 x 7) from the total number of points he needs to reach the bonus (60).Divide the result by the number of points he earns for each hole on which he scores a 4 (4).So X = (60 - (4 x 7)) / 4 = (60 - 28) / 4 = 32 / 4 = 8Therefore, Zaire needs to score a 4 on 8 holes today to get the bonus.

The greatest number of different lines that can be drawn so that each line passes through two of these points is 36. This is because every pair of points can be connected by a line, and with ten points, there are 45 pairs. Since each line can only be drawn once, the total number of different lines that can be drawn is 45 divided by two, which is equal to 36. In addition, the number of lines that can be drawn from each point to the rest of the points is 9, and since there are 10 points, the total number of lines that can be drawn is 90. However, this number is redundant since each line can only be drawn once, so the greatest number of lines that can be drawn is 36.

What are coordinates of graph?

Coordinates X and Y axes are present in every graph. Positions on a graph are indicated using coordinates, which are expressed as an ordered pair of numbers.

ABCD is a square with A(-3,2) & C(0,5).

To find out-

The coordinates of B & D

Solution-

Let the coordinates of B=(x,y).

Since ABCD is a square,

[tex]AB=BC=AB^2=BC^2.[/tex]

Using distance formula,

[tex](x-3)^2+(y-2)^2=(x-0)^2+(y+5)^2[/tex]

⟹2x+8y−6=0

⟹x=([tex]\frac{6-8y}{2}[/tex] ) .........(i).

Now, in ΔABC,

[tex]AB ^2+BC ^2=AC ^2[/tex]

[tex](x-3)^2+(y-2)^ 2+(x-0) ^2 +(y+5)^ 2=(3-2) ^2+(0+5) ^2[/tex]

⟹[tex]x^ 2+y ^2 -3x-3y=0.[/tex]

Substituting for x from (i),

[tex](\frac{6-8y}{2} )^2+y ^2 -3(\frac{6-8y}{2} )-3y=0[/tex]

⟹[tex]3y^2-9y+4=0[/tex]

⟹[tex](2y-1)(2y-4)=0[/tex]

⟹[tex]y=( \frac{1}{2},\frac{4}{2} ).[/tex]

Substituting for y in (i),

[tex](x,y)=( \frac{9}{2},\frac{1}{2} ) & (-\frac{1}{2} , \frac{4}{2} )[/tex]Now abscissae of A & C are 3 & 1, respectively.

∴  Abscissa of B will be in between 1 & 3.

So here,  [tex]\frac{9}{2}[/tex] will be the abscissa of B.

 Coordinates of B & D are [tex](\frac{9}{2} ,\frac{1}{2} ) & (-\frac{1}{2} ,\frac{4}{2} )[/tex] respectively.

The coordinates of the remaining vertices B and D are (0, 2) and (-3, 5) respectively.

What are the coordinates of the vertices?

The unit square precisely refers to the square on the Cartesian plane having four corners.

Since square ABCD has a diagonal with the given vertices A(-3, 2) and C(0, 5), we know that the other two vertices of the square will be B and D, and that all four sides of the square are congruent.

We can use the coordinates of A and C to find the coordinates of B and D.

First, we know that the x-coordinate of B must be the same as the x-coordinate of C because the side BD is parallel to the x-axis.

Therefore, the x-coordinate of B is 0.

Next, we know that the y-coordinate of B must be the same as the y-coordinate of A because the side AB is parallel to the y-axis.

Therefore, the y-coordinate of B is 2.

So, the coordinates of B are (0, 2).

Finally, we know that the x-coordinate of D must be the same as the x-coordinate of A because the side AD is parallel to the x-axis.

Therefore, the x-coordinate of D is -3.

Next, we know that the y-coordinate of D must be the same as the y-coordinate of C because the side CD is parallel to the y-axis.

Therefore, the y-coordinate of D is 5.

So, the coordinates of D are (-3, 5)

Therefore, the coordinates of the remaining vertices B and D are (0, 2) and (-3, 5) respectively.

Recall the equation for a circle with centre (h,k) and radius r. At what point in the first quadrant does the line with equation y=1.5x+5 intersect the circle with radius 5 and centre (0,5)?

Answers

The equation for the circle is (x-h)^2 + (y-k)^2 = r^2. Substituting the values, we get (x-0)^2 + (y-5)^2 = 25.

Substituting y=1.5x+5 into the equation, we get (x-0)^2 + (1.5x+5-5)^2 = 25

Simplifying, we get 1.5x^2 +15x+25=25

Solving, we get x=1.

Therefore, the point of intersection is (1,1.5).

The line y=1.5x+5 intersects the circle with radius 5 and centre (0,5) at the point (1,1.5) in the first quadrant.

The equation for a circle with centre (0,5) and radius 5 is (x-0)^2 + (y-5)^2 = 25. When this equation is combined with the line equation y=1.5x+5, it can be solved to find that the line intersects the circle at the point (1,1.5), which is located in the first quadrant.

The equation for the circle is (x-h)^2 + (y-k)^2 = r^2. Substituting the values, we get (x-0)^2 + (y-5)^2 = 25.

Suppose y varies directly with x. Write a direct variation equation that relates x and y. y=5 and x=2

Answers

A direct variation equation that relates x and y is y = (5/2)x.

What is the direct variation equation?

Direct variation is a linear function defined by an equation of the form y = kx when x is not equal to zero. Inverse variation is a nonlinear function defined by an equation of the form xy = k when x is not equal to zero and k is a nonzero real number constant.

When two variables are directly proportional, they vary directly with each other.

The relationship between the variables can be represented by a direct variation equation of the form:

y = kx

where k is the constant of proportionality.

Given that y = 5 and x = 2, we can use these values to find the value of k:

y = kx

5 = k(2)

k = 5/2

So the direct variation equation that relates x and y is:

y = (5/2)x

This equation shows that for every value of x, the value of y is 5/2 times that value.

For example, if x = 3, then y = (5/2) * 3 = 7.5, and if x = 4, then y = (5/2) * 4 = 10.

Hence, A direct variation equation that relates x and y is y = (5/2)x.

Answers

The lengths of the segments into which the bisector of each angle divides the opposite side: 12.7, 20.4 and 9.8 respectively

How to find the lengths?

The median of a triangle is defined as the length of a line segment that extends from a vertex of the triangle to the midpoint of the opposing side. A triangle can have three medians, all of which will intersect at the centroid (the arithmetic mean position of all the points in the triangle) of the triangle

The medians of the triangle are represented by the line segments ma, mb, and mc. The length of each median can be calculated as follows:

Ma = √(2b²) + (2c²) - a²

. Mb = √(2a²) + (2c²) - b²

Mc = √(2a²) + (2b²) - c²

Applying the formulas

⇒Ma = √(2*3²) + (2*11²) - 10²

Ma = √(18) + (242) - 100

Ma = √160

Ma = 12.7 units

Mb = √(2a²) + (2c²) - b²

Mb = √(2*10²) + (2*11²) - 3²

9^10 divided by 9 can be simplified to 9^(10-1) = 9^9

This is because when dividing a power by the same base, we can subtract the exponent by one.

In other words, 9^10 / 9 = (9999999999) / (9) = 99999999*9 = 9^9.

So, 9^10 divided by 9 is equal to 9^9.

Another way to think about this is that dividing a number by itself is the same as multiplying that number by 1, and 9^10 / 9 = 9^10 * 1 / 9 = 9^10 / 9^1 = 9^(10-1) = 9^9

In terms of real numbers, 9^10 is equal to 387420490 and 9^9 is equal to 3486784401. So 9^10 divided by 9 is equal to 3486784401.

The distribution of IQ (Intelligence Quotient) is approximately normal in shape with a mean of 100 and a standard deviation of 20.
According to the standard deviation rule, ____% of people have an IQ between 80 and 120. Do not round.

Answers

Using the Empirical Rule, it is discovered that the proportion of people in a population with IQs ranging from 80 to 120 is 0.95 = 95%.

What is Empirical Rule?

It specifies the following for a normally distributed random variable:

68% of the measurements are within one standard deviation of the mean.

95% of the measurements are within 2 standard deviations of the mean.

99.7% of the measurements are within 3 standard deviations of the mean.

Given a mean of 100 and a standard deviation of 20, we can calculate:

80 = 100 - 2 x 20.

120 = 100 + 2 x 20.

Because these are both the most extreme values within two standard deviations of the mean, then the proportion of people in a population with IQ scores between 80 and 120 is 0.95 = 95%.

Given right triangle ABCABC with altitude \overline{BD}BDdrawn to hypotenuse ACAC. If AC=12AC=12 and DC=4,DC=4, what is the length of \overline{BC}BCin simplest radical form?

Answers

The length of the side BC of right triangle ABC can be found by applying the Pythagorean theorem with AC = 12 and DC = 4. The length of BC can be expressed in simplest radical form.

Using the Pythagorean Theorem, BC^2 = AC^2 - DC^2

= 12^2 - 4^2

= 144 - 16

= 128

Therefore, BC = [tex]\sqrt{128}[/tex]= 2[tex]\sqrt{32}[/tex] = 8[tex]\sqrt{2}[/tex]

The length of the side BC of a right triangle ABC can be found by applying the Pythagorean theorem. The Pythagorean theorem states that the sum of the squares of the two legs of a right triangle is equal to the square of the hypotenuse. In this case, AC = 12 and DC = 4, so BC^2 = AC^2 - DC^2 = 144 - 16 = 128. Therefore, which is the length of \overline{BC}BC in its simplest radical form. This result can be verified by calculating the length of the hypotenuse AC and confirming that it is equal to the square root of the sum of the squares of BC and DC.

Answers

The equation that shows the number of pounds of celery(y) the cook will use each day is 8y+17= 31 and y = 1 ¼

What is linear equation?

A linear equation is an algebraic statement where each term is either a constant or a variable raised to the first power. In other words, none of the exponents can be greater than 1.

For each day , the cook will use 2 1/8 pounds of carrot and y pounds of celery

therefore total = 17/8 +y

for 5 days the total carrot and celery used =( 17/8 + y) ×5

for 5 days 19 3/8 pounds of carrot and celery is used . Therefore;

155/8 = 5(17/8+y)

for each day, divide both sides by 5

155/8×1/5 = 17/8+y

31/8 = 17/8+y

collect like terms

y = 31/8-17/8

multiply through by 8

8y = 31-17

8y+17 = 31

therefore the equation that can be used to find the pound of celery used per day is 8y+17= 31
