Answer:

Step-by-step explanation:

It's not A and B because an exponent to the negative number leads to the fraction.

e.g. 10^-a = 1/(10^a)

It's not D because 5,030,000 rounds to 5,000,000 and not 6,000,000.

Answer:

15/2 or 7.5 :)

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]\frac{6}{15} = \frac{3}{x}[/tex]

simply cross multiply

[tex]6x = 45[/tex]

divide both sides by 6

[tex]\frac{6x}{6} = \frac{45}{6}[/tex]

hence x will be equal to [tex]7.5[/tex]

Find the perimeter of the figure to the nearest hundredth. due today

Answers

Answer:

42.84 cm

Step-by-step explanation:

1) Find the perimeter of the top trapezoid. (In cm) 6 + 8 + 12 + 10 = 36 cm

2) Find the circumference of the semicircle with the formula 0.5(pie times D) where D is the diameter. Another formula is 0.5(pie times 2r) where r is the radius. Approximate pie to 3.14 so we should get 0.5 * 3.14 * 12 = 18.84 cm

3) We do not need the length of the base of the trapezoid so we take 36 + 18.84 - 12 = 42.84 cm

What is the circumference of the outer edge of the path around the pool?

Answers

Add the radius of the pool to the width of the path to get the radius of the path (15 + 3 = 18). Using 2(pi)r = Circumference, we get 36(pi). If you multiply 36x3.14 you get 103.4 ft.

The point D(2, -5) is rotated 90° counterclockwise around the origin. What are the coordinates of the resulting point, D′?

Answers

Answer:

D' = (5, 2)

Step-by-step explanation:

Try to join D and the origin using a line. Counterclockwise means in an opposite direction of rotation of the clock hands. So draw another line towards the right which is perpendicular to the previous line to fine the answer. Remember the length of the lines should be equal.

the perimeter of a rectangle is 15x+17y. if the length is 7/2x+7y, then find the width of the rectangle
A.) 4x+3/2y
B.) 8x+3y
C.) 8x+10y
D.) 4x+3y

Answers

Answer:

Step-by-step explanation:

Length : [tex]\frac{7x}{2} + 7y[/tex]

Perimeter: [tex]15x + 17y[/tex]

Perimeter = 2(Length + Width)

15x + 17y = 2( [tex]\frac{7x}{2} + 7y[/tex] + Width)

15x + 17y = 7x + 14y + 2(Width)

15x + 17y -7x -14y = 2(Width)

8x + 3y = 2(Width)

Width = [tex]\frac{8x + 3y}{2}[/tex]

Width = 4x + 3y/2

A researcher wants to know if there is a relationship between the number of shopping centers in a state and the retail sales (in billions $) of that state. A random sample of 8 states is listed below. After determining, via a scatter-plot, that the data followed a linear pattern, the regression line was found. Using the given data and the given regression output answer the following questions.
State Num Sales
1 630 15.5
2 370 7.5
3 616 13.9
4 700 18.7
5 430 8.2

Paste the table with the results of regression analysis.

Answers

Answer:

Kindly check explanation

Step-by-step explanation:

Given the data:

Num shopping centers (X) :

630

370

616

700

430

558

1200

2976

Sales (Y) :

15.5

7.5

13.9

18.7

8.2

13.2

23.0

87.3

The regression equation obtained using the online regression calculator is :

y = 0.03025X - 4.87014

2.) The slope value, for every unit change in number of shopping centers, the number of sales increases by 0.03025

3.)

The Coefficient of determination (R²) as obtained by the R² value calculator is : 0.9823

4.)

About 98% of variation in number of sales is explained by the regression line

5.)

Correlation Coefficient = 0.9911

H0 : p ≥ 0.99

H1 : p < 0.99

Answer:

P = 228 inches

Step-by-step explanation:

P = 2(l + w)

l = 97 inches

w = 17 inches

P = 2 (97 + 17)

P = 2 x 114
