confidence intervals for the means provide an estimate for where the true mean lies.

Reason:

We have 50 mint condition coins out of 250 total

This forms the ratio 50:250, in which we divide both parts by the GCF 50 to end up with 1:5

The ratio 1:5 tells us that the total is 5 times that of the number of mint condition.

Using the sample space, the probability of rolling an even number with a six-sided dice is 3/6 or 1/2.

In the given question we have to find the probability of rolling an even number with a six-sided dice.

The sample space of dice through the experiment is

{1,2,3,4,5,6}

The even numbers is {2,4,6}.

The probability of rolling an even number with a six-sided dice is

P(E)=Total number of even outcome/Total number of outcome

P(E)=3/6

P(E)=1/2

Hence, the probability of rolling an even number with a six-sided dice is 3/6 or 1/2.

In the coordinate plane, line p has slope 13 and y-intercept (0, 2). Line r is the result of dilating line p by a factor of 3 centered at the origin.

Line P

Slope (m) = 13

y intercept is (0,2)

Equation is

y = mx+y

y= 13x+2

Dilated by scale factor of 3 with center at (0,3)

First make the centre at origin (0,0) by shifting the line 3 units downwards.

y = (13x+2)-3

y = 13x-1

In case of dilation, slope remains same only the y-intercept gets multiplied.

New equation is y = 13x-(1x3)

y = 13x-3

Now again take this line 3 units upwards

y = (13x-3)+3

y = 13x+0

Hence line r has slope of 13, y intercept is (0,0)

The greatest number of 150-kilogram crates that can be loaded into the shipping container are 138

Greatest weight that can be loaded = 27500 kilograms

Weight of each crate = 150 kilogram

Weight of other shipments = 6800 kilograms

Let c be the greatest number of 150 kilogram crates that can be loaded.

The required inequality

27500 ≥ 6800 + 150c

27500 - 6800 ≥ 150c

20700 ≥ 150c

c ≥ 20700/150

Based on the information, the two integers are 30 and 31.

Let the first integer be x. The second consecutive integer will be (x + 1).

So, the smaller integer = 2x

The larger integer = 3(x + 1)

Their sum = 153

Forming the equation now -

2x + 3(x + 1) = 153

Performing multiplication on Left Hand Side of the equation

2x + 3x + 3 = 153

Performing addition on Left Hand Side of the equation

5x = 153 - 3

Performing subtraction on Right Hand Side of the equation

5x = 150

x = 150/5

Performing division on Right and Side of the equation

x = 30

To find the missing values for the exponential function represented by the table above.

An exponential function is in general form, that is

[tex]f(x) = y = a(b)^{x}[/tex]

Now, given points are (-2,8), (-1,12), (0,18)

First let us consider

f(x) = 8 at x = -2

[tex]f(x) = a(b)^{x}[/tex]

[tex]f(-2) = a(b)^{-2}[/tex] = 8

[tex]\frac{a}{b^{2} } = 8[/tex]

So, [tex]a = 8b^{2}[/tex]  lets consider this as equation 1

second let us consider

f(x) = 12 at x = -1

[tex]f(-1) = a(b)^{-1} = 12[/tex]

[tex]\frac{a}{b} = 12[/tex]

a = 12b  lets consider this as equation 2

From equations 1 & 2, we have

[tex]8b^{2} = 12b[/tex]

[tex]8b^{2}-12b = 0[/tex]

4b(2b-3) = 0

b = 0 or [tex]\frac{3}{2}[/tex]

This is not possible otherwise function will not remain exponential.

[tex]b = \frac{3}{2} ,[/tex] so putting b in equation 1

we have [tex]a = 12b = 12x\frac{3}{2} = 18[/tex]

therefore a = 18

therefore [tex]f^{n} = f(x) = 18(\frac{3}{2})^{x}[/tex]

1. [tex]f(1) = 18(\frac{3}{2})^{1} = 27\\[/tex]

f(1) = 27

2. [tex]f(2) = 18(\frac{3}{2})^{2} = \frac{81}{2} = 40.5[/tex]

The number of red sectors is given as 2.

Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.

The probability of any event always lie in the close interval of 0 and 1 [0,1].

Given that,

The total number of sectors on the fortune wheel is 5.

And, the probability of getting red colour is 40%.

Which is equivalent to 40/100 = 0.4.

The probability of getting red is given as,

P(red) = Number of red sectors ÷ Total number of sectors

=> 0.4 = Number of red sectors  ÷ 5

Answer:

  -3

Step-by-step explanation:

You want the slope of the line through points (1, 2) and (3, -4).

The slope of the line is its "rise" divided by its "run." The values of these can be found several ways. Perhaps the easiest is to count the squares on the graph.

The bottom point on the graph is 2 grid squares to the right of the top point, and 6 grid squares below it. The "rise" is -6 (down is negative), and the "run" is 2. The slope is ...

  slope = rise/run = -6/2 = -3

You can also use the slope formula with the coordinates of the points.

  m = (y2 -y1)/(x2 -x1)

  m = (-4 -2)/(3 -1) = -6/2 = -3

The slope of the line is -3.

[tex]\frac{2}{3}[/tex] × [tex]\frac{4}{1}[/tex]

We multiply numerator times numerator and denominator times denominator to get [tex]\frac{8}{3}[/tex].  If we convert that improper fraction to a mixed number fraction we get [tex]2\frac{2}{3}[/tex].

The number of cups of milk would be 2 2/3 needed in the four milkshakes.

A ratio is defined as a relationship between two quantities, it is expressed as one divided by the other

We have been given that martin is making four milkshakes. The recipe calls for 2/3 cup of milk.

We have to determine the number of cups of milk he needs

Let the number of cups of milk would be x in the four milkshakes.

As per the given situation, we can write the ratio would be as:

1 milkshakes : 2/3 cup of milk = 4 milkshakes : x cup of milk

⇒ 1 / (2/3) = 4/x

Reciprocal the term in the numerator,

⇒ 3/2 = 4/x

Apply the cross-multiplication operation,

⇒ 3x = 8

⇒ x = 8/3

⇒ x = 2 2/3

According to the Pythagoras theorem, the exact value of tan A is 3/4 and the value of tan B is 15/8

Pythagoras Theorem

Pythagoras theorem defines that “In a right-angled triangle, the square of the hypotenuse side is equal to the sum of squares of the other two sides“

Given,

Here we have the value of sin A = 3/5, cos B = 8/17 and A and B are acute angles.

And we need to find the value of tan A and tan B.

According to the Pythagoras theorem,

If the value of sin A = 3/5, then we have the value of the right angle triangle of hypotenuse and the opposite.

So, the adjacent value is calculated based on the theorem is,

=> 5² = ad² + 3²

=> 25 = ad² + 9

=> ad² = 25 - 9

=>  ad = √16

=> ad = 4

Therefore, the value of tan A is written as,

=> tan A = opposite/ adjacent

=> tan A = 3/4

Similarly, the value of tan B is calculated as,

If the value of cos B = 8/17, then we have the value of the right angle triangle of hypotenuse and the adjacent.

So, the opposite value is calculated based on the theorem is,

=> 17² = 8² + op²

=> 289 = 64 + op²

=> op² = 289 - 64

=> op = √225

=> op = 15

Therefore, the value of tan B is written as,

=> tan B = opposite/ adjacent

=> tan B = 15/8

Answer: True

Step-by-step explanation:

If all the integers are positive, the only answer you get when multiplying them all is positive. If one of the three integers is negative, then the product is negative because if you have 2*3*(-1), the answer would be -6. But if you have 2*3*1, the answer is 6. If two of the three integers are negative, then the product is positive given the third integer is positive because a negative times a negative is a positive.  

Answer:

x = 9

Step-by-step explanation:

Triangles are similar due to AAA (all angles are congruent due to shared angle and corresponding angles). Thus, the sides are proportional, and we can set up a proportion with corresponding sides:

9/(72 + 9) = (3x - 20)/(3x - 20 + 56)

9/81 = (3x - 20)/(3x + 36)

(1/9) * (3x + 36) = 3x - 20

(3x + 36)/9 = 3x - 20

3x + 36 = (3x - 20)*9

3x + 36 = 27x - 180

36 + 180 = 27x - 3x
