The given graph shows the relationship between the social media posts and grade point average of different students in Brent's class.

From the given graph, we can say that the grade point average of students decrease with increase in number of their social media posts.  

Since grade point average decreases approximately linearly with increase in use of social media posts, It is Strong negative correlation.

Hence, option D is correct i.e. Strong Negative Correlation.

Answer:

C. 28 = (2x - 1)(x)

Step-by-step explanation:

There is a rectangular swimming pool.

Width of swimming pool is x  

Length is  one less than twice the width

Area of the swimming pool is  28 sq ft.

To Find : Equation could be used to model the area of the swimming pool.

Solution:  

Since we are given that Length is one less than twice the width.

And width is x (given)

So, length = 2x-1

Area of the swimming pool is  28 sq ft.

Now ,

Formula of area of rectangle : Length*Width

⇒28= (2x-1)(x)

So,  equation used to model the area of the swimming pool: 28= (2x-1)(x)

Hence Option c is correct.

Answer:

32 m^2

Step-by-step explanation:

First find the volume of the bottom section

V = l * w*h

V = 6 * 2 * 2 = 24 m^2

Then find the volume of the top section in green

The length is 6-4 =2,  the height is 4-2, width is 2

V = = l*w*h = 2*2*2 = 8

Ad the volumes together

V = 24+8 = 32 m^2

What is the surface area of the cube?
tia_tia [17]

Answer:

96 mm^2

Step-by-step explanation:

because the cube has 6 sides and one side has a 16 mm surface area, so you would take that one sides surface area and multiply it by 6 because the cube has 6 sides, so 16*6=96 mm^2. :) arigato

Jamie invests part of $10,000 at 9% annual interest and the rest at 8%. If his annual income from
vazorg [7]

Answer:

$4000

Step-by-step explanation:

Assuming a = money invested at 9%

Assuming b = money invested at 8%

then we can form am equation from the question given

1) a + b = $10000, also

0.09a + 0.08b = $860 -> multiply by 100

2) 9a + 8b = $86000

Next we try to solve both equations simultaneously. We multiply both the left hand side and the right hand side of the first equation by 8. We have

3) 8a + 8b = $80000, now we subtract 3 from 2

9a + 8b = $86000

-8a - 8b = -$80000

a = $6000.

Then, we plug this in any of the first 2 equations, to get b

9 * $6000 + 8b = $86000

$54000 + 8b = $86000

8b = $86000 - $54000

8b = $32000

b = $32000/8

b = $4000.

Therefore, he invested $4000 at 8%
