The sample minimum isn't an unbiased estimator as D. The mean of the sampling distribution of the sample minimums is 16, which is not 15.

A sampling distribution simply means a probability distribution that is obtained from a larger number of samples drawn from a population.

From the complete question, the sample minimum isn't an unbiased estimator as the mean of the sampling distribution of the sample minimums is 16, which is not 15.

In this case, the minimum of the ages of the officer is 15.

Answer:

(a) h(t) = 3

(b) time = 1.36 seconds

Explanation:

equation: h(t) = -16(t)² + 24t

If the fielder catches the ball at the height of about 3 ft.

using graphing technology, graphed below. (height, y = 3)

Additional *solving part B algebraically*

-16(t)² + 24t = 3

-16(t)² + 24t - 3 = 0

using quadratic equation

Based on the histogram, the interquartile rangle of the distribution is 5 inches.

The interquartile range is the difference between the third quartile of a data set and the first quartile of the data set.

First quartile = 1/4 x ( n + 1)

= 101 / 4 = 25.25

25.25 on the histogram is 66

Third quartile = 3/4 x (n + 1)

303 / 4 = 75.75

75.75 on the histogram is 71

Interquartile range = 71 - 66 = 5

the question states that a person named Ben has two copies of the same poster having different sizes , provided they both are squares !

further , we've been given that the side length of the posters are in the ratio of 3:7 and the perimeter of the smaller posted is 27 cm .

We've been asked to find the perimeter of the bigger poster !

so let's start ~

[tex]let\: the \: length \: of \: the \: smaller \: poster \: be \: 3x \\ \\ let \: the \: length \: of \: the \: bigger \: poster \: be \: 7x \\ \\ now \: , \: \\ \\ perimeter \: of \: square = 4 \times side \\ \\ \implies \: perimeter \: of \: shorter \: square = 4 \times 3x \\ \\ \implies \: 27 = 3x \\ \\ x = \cancel\frac{27}{3} \\ \\ \implies\red{\boxed{ \: x = 9 \: cm}}[/tex]

now ,

[tex]side \: length \: of \: bigger \: square = 7x \\ \\ \implies \: 7 \times 9 = 63 \: cm \\ \\ \therefore \: perimeter \: of \: bigger \: square = 4 \times 63 \\ \\ \bold\pink{\implies \: 252 \: cm}[/tex]

Answer:

  $70

Step-by-step explanation:

The additional amount Stan needs will be the difference between his expected costs and the amount he has saved.

__

  $19,700 +125 +245 = $20,070

  $20,070 -20,000 = $70

Stan will need $70 more to cover the cost of the garage, permit, and insurance.

Answer:

The correct option is C. The function [tex]f(x)=\frac{5}{4}(\frac{4}{5})^x[/tex] is a stretch of an exponential decay function.

Step-by-step explanation:

The general form of an exponential function is

[tex]f(x)=ab^x[/tex]

where, a is the initial value and b is the growth factor.

If b<1, then it represents a decay function and if b>1, then it represents a growth function.

Let k be a stretch and compression factor.

[tex]g(x)=kf(x)[/tex]

If k<1, then it represents vertical compression and if k>1, then it represents vertical stretch.

In third function

[tex]f(x)=\frac{5}{4}(\frac{4}{5})^x[/tex]

[tex]k > 1[/tex]

[tex]b < 1[/tex]

Therefore the function [tex]f(x)=\frac{5}{4}(\frac{4}{5})^x[/tex] is a stretch of an exponential decay function.

Answer:

Below!

Step-by-step explanation:

Since the "y" variable is on the L.H.S, we can rewrite y = 5 in slope intercept form to determine the slope and the y-intercept.

Now, let's compare the equation of the line with the formula.

Thus, we will obtain the following equations:

============================

Thus, the slope is 0 and the y-intercept is 5. Since the slope is 0, the line will be a horizontal line that intersects the y-intercept.

In this case, the y-intercept is 5. Thus, the line will be a horizontal line, intersecting the y-intercept (5). (Refer to graph).

If we simplify

Since there are 18 gallons at the beginning of the trip you divide by 2.5 to find out how much gas is left after each hour.

The true statement is that the p-value is a probability that measures the support (or lack of support) for the null hypothesis.

In a statistical test, the p-value validates or invalidates the null hypothesis

This means that

Answer:

Step-by-step explanation:

A reasonable estimate could be 14,300, or 14,000, or also you could do 14,290

If 13/15 was building then that means 2/15 was land( 1-13/15 = 2/15)

Multiply the total cost by 2/15

600 million x 2/15 = 80 million

the land cost 80 million

Answer:

To find the perimeter of this triangle, we add up all the sides together.

(8 · √3) + (8 · √3) + √384

But before we add them, let's simplify them.

(8 · 1.7) + (8 · 1.7) + 19.6

13.6 + 13.6 + 19.6

27.2 + 19.6

= 46.8, is the perimeter of this triangle.

Now to find the area, we use the formula:

(formula for area of a triangle)

A = BH · 1/2

Where 'B' represents the base, 'H' stands for the height, and 1/2 means that you divide the product of the base and height by 2.

What we know:

Plug in the values into our formula:-

A = BH · 1/2

A = 13.6(13.6) · 1/2

A = 184.96 · 1/2

A = 184.96/2

A = 92.48, is the area for this triangle.

Answer:

8.5

Step-by-step explanation:

area of a rhomus = (1/2)(product of its diagonals)

let the other diagonal be a

(1/2)(15a) = 60

15a= 120

a = 8

So let's find the hypotenuse of one of the right-angled triangles formed by the intersection of its diagonals

base = 4, height = 7.5

if h is the hypotenuse,

h^2 = 4^2 + 7.5^2

h = 8.5
