It will cost $14,400 to do the triangle the hotel plans to do.

The area of a triangle is half the base times the height:

A=\dfrac{b\cdot h}{2}

Thus, the area of the marble section is:

A=\dfrac{80 \cdot 60}{2} = 2,400 \text{ square feet}

If every square foot costs $6, the total cost is:

2,400 · 6 = $14,400

For a recent report on sleep deprivation, the Centers for Disease Control and Prevention interviewed 11600 residents of Californ
Pani-rosa [81]

Answer:

H0: p1-p2=0

Ha: p1-p2≠0

This hypotheses can be written as

H0: p1=p2

Ha: p1 ≠p2  

Step-by-step explanation:

Here the claim is if these data provide strong evidence the rate of sleep deprivation is different for the two states which will be formulated as alternate hypothesis .

Ha: p1-p2≠0  

The null hypothesis is

H0: p1-p2=0  i.e these data  do not provide strong evidence the rate of sleep deprivation is different for the two states.

where p1  =   as population 1 of California

p2= as population 2 of Oregon

This hypotheses can be written as

H0: p1=p2

Ha: p1 ≠p2  

which will also give the same results as above and a two tailed test will be performed for both hypotheses.

Find the x-intercept and y-intercept for 8x-9y=15
Kipish [7]

The  x and y-intercept of the equation [8x - 9y = 15] are ( 15/8, 0 ) and ( 0, -5/3 ) respectively.

<h3>What are the x and y-intercept?</h3>

Given the equation;

8x - 9y = 15

First, we find the x-intercepts by simply substituting 0 for y and solve for x.

8x - 9y = 15

8x - 9(0) = 15

8x = 15

Divide both sides by 8

8x/8 = 15/8

x = 15/8

Next, we find the y-intercept by substituting 0 for x and solve for y.

8x - 9y = 15

8(0) - 9y = 15

- 9y = 15

Divide both sides by -9

- 9y/(-9) = 15/(-9)

y = -15/9

y = -5/3

We list the intercepts;

x-intercept: ( 15/8, 0 )

y-intercept: ( 0, -5/3 )

Therefore, the  x and y-intercept of the equation [8x - 9y = 15] are ( 15/8, 0 ) and ( 0, -5/3 ) respectively.

What is the solution of 5y=-1x and 10y=-2x
Nana76 [90]

the key is to get y by itself.

5y=-1x

divide each side by 5

y=-1/5x

now plug in that for y in the second equation

10(-1/5)=-2x

combine your like terms

-2=-2x

then divide each side by -2

x=1

now put them in an ordered pair.

(1,-1/5)
