A real estate agent believes that the value of houses in the neighborhood she works in has increased from last year. To test this claim, she selects random houses in this neighborhood and compares their estimated market value in the current year to their estimated market value in the previous year. Suppose that data were collected for a random sample of 8 houses, where each difference is calculated by subtracting the market value of the previous year from the market value of the current year. Assume that the values are normally distributed. The agent uses the alternative hypothesis Ha:μd>0. Using a test statistic of t≈7.496, which has 7 degrees of freedom, determine the range that contains the p-value.

Hello!

This is an equilateral triangle. In this triangle, the angles are congruent, respectively, the sides. Here, the mediator corresponds to the bisector, the median. So this line will form two  right triangles.

Th 30-60-90

I used the 30-60-90 theorem, which says that the opposing the angle of 30 degrees has the length equal to half the hypotenuse.

Th Pitagora's

Which states that the sum of the squares of the legs of a right triangle is equal to the square of the hypotenuse.

Good luck:)

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

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

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:

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:

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
