A statistician believes that the percent population growth rate of major cities has decreased compared to the last decade. To test his claim, he randomly selects major cities and compares the percent population growth between the years 2007 and 2017 to the percent population growth between the years 1997 and 2007. Suppose that data were collected for a random sample of 17 cities, where each difference is calculated by subtracting the percent growth rate from 1997 to 2007 from the percent growth rate from 2007 to 2017. Assume that the percentages are normally distributed. The statistician uses the alternative hypothesis Ha:μd<0. Using a test statistic of t≈−5.053, which has 16 degrees of freedom, determine the range that contains the p-value.

Answer:

a n= - 3a_{n-1}a n−1 with a₁ = - 0.3

Step-by-step explanation:

The recursive formula for a geometric sequence is of the form

a_{n}a

n = ra_{n-1}a

n−1

where r is the common ratio

r = \frac{a_{2} }{a_{1} }

a

1

a

2

= \frac{0.9}{-0.3}

−0.3

0.9

= - 3 , thus

a_{n}a

n

= - 3a_{n-1}a

n−1

with a₁ = - 0.3

Answer:

d. {(-2, 5), (-1, 2), (0, 1), (1, 2), (2, 5)}; Domain: {-2, -1, 0, 1, 2}; Range: {1, 2, 5}

Step-by-step explanation:

Part A:

Domain = the set of all x-values plotted on the x-axis = {-2, -1, 0, 1, 2}

Range = the set of all possible y-values on the y-axis that corresponds with the x-values = {1, 2, 5}

Part B:

The set of coordinates that describes the function on the graph are:

When x = -2, y = 5 => (-2, 5)

When x = -1, y = 2 => (-1, 2)

When x = 0, y = 1 => (0, 1)

When x = 1, y = 2 => (1, 2)

When x = 2, y = 5 => (2, 5)

The set of coordinates is:

{(-2, 5), (-1, 2), (0, 1), (1, 2), (2, 5)}

Answer:

Step-by-step explanation:

Answer:

If we classify the shapes shown in the picture, we can see that there are 4 triangles and one square.

First, we need to find out the formulas for the areas of these shapes.

Formula for area of triangle;

A = BH x 1/2

where b represents the base, and h represents the height

Formula for area of square;

A = a^2

where 'a' represents the length of one side of a square

Now we just plug in the actual values to these formulas:-

(Finding area of square first)

A = a^2

A = 2^2

A = 4

Now, we find the area of one triangle and multiply it by 4 because there are  four of each of those triangles.

A = BH x 1/2 x 4(no. of triangles)

A = 2(3) x 1/2 x 4

A = 6 x 1/2 x 4

A = 6/2 x 4

A = 3 x 4

A = 12

Now we add the two areas together;

4 + 12 = 16 square feet

Answer:

y=8

Step-by-step explanation:

Answer:

Y = 8

Step-by-step explanation:

To solve this equation, you must isolate the variable (y).

To do this, let's add 15 to both sides.

-15+3y = 9

+15         +15

3y = 24

Then, we need to divide each side by 3, in order to get y alone.

y = 8

Answer:

5.72?

Step-by-step explanation:

5.73-0.01=5.72

Answer:

5.72 ounces

Step-by-step explanation:

It is very simple.

Subtract the 0.01 ounces of milk chocolate from the total amount of chocolate

5.73 - 0.01 = 5.72

Wyatt bought 5.72 ounces of dark chocolate.

Answer:

14.7

Step-by-step explanation:

x = 22 * sin(42) = 14.7

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

Explanation:

Convert the x = 82 to a corresponding z score.

z = (x-mu)/sigma

z = (82 - 89)/7

z = -7/7

z = -1

Using the empirical rule (see chart below), roughly 68% of the distribution is within 1 standard deviation of the mean.

This leaves 1 - 0.68 = 0.32 = 32% of the distribution in both tails, and (32%)/2 = 16% of the area is in one tail, which converts to 0.16

About 16% of the normally distributed population is below z = -1.

So we can say [tex]P(x \le 82) = P(z \le -1) \approx 0.16[/tex]

z value:-

[tex]\\ \rm\Rrightarrow \dfrac{x-\overline{x}}{\sum}[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{82-89}{7}[/tex]

[tex]\\ \rm\Rrightarrow \dfrac{-7}{7}[/tex]

[tex]\\ \rm\Rrightarrow -1[/tex]

As per z value chart

Answer:

40 and 42

Step-by-step explanation:

Let the two even numbers be x and x+2.

"One-fifth of an even number:"  (1/5)x

"one-sixth of the next even number:"  (1/6)(x+2)

Added they make 15:  (1/5)x + ((1/6)(x+2)) = 15

(1/5)x + ((1/6)(x+2)) = 15

(1/5)x + (1/6)x+(1/6)*2 = 15

(1/5)x + (1/6)x+(2/6) = 15

(6/30)x + (5/30)x = 15 - (1/3)

(11/30)x = (45/3) - (1/3)

(11/30)x = (44/3)

x = (30/11)*(44/3)

x = 40

x + 2 = 42

Check:

Does

(1/5)(40) + (1/6)(42) = 15?

8 + 7 = 15   YES

The two even numbers are 40 and 42
