Dimas [21]

Answer:

$17.14

Step-by-step explanation:

Given : y = - 0.34x^2 + 4.43x + 3.46

To Find : Using the quadratic regression equation, what was the predicted profit in year 8

Solution :

y = - 0.34x^2 + 4.43x + 3.46

Where y is profit and x is year

Substitute x = 8

y = -0.34(8)^2 + 4.43(8) + 3.46

y =17.14

So, Option D is true

Hence the predicted profit in year 8 is $17.14

Identify the angle measures of PQRS. I'm so confused, please help me! SHOW YOUR WORK!!
Dennis_Churaev [7]

10y + 7 + 3(3y + 7) = 180

10y + 7 + 9y + 21 = 180

19y + 28 = 180

19y = 180 - 28

19y = 152

y = 152/19

y = 8

Plug back into Q and S.

Q = 10y + 7

Q = 10(8) + 7

Q = 80 + 7

Q = 87

S = 3(3y + 7)

S = 9y + 21

S = 9(8) + 21

S = 72 + 21

S = 93

Without solving for x to find the other angles, we can easily see that the answer is choice C.

Answer:

P = 61°

Q = 87°

R = 119°

S = 93°

Done!

A group of 52 people attend a ball game there were three times as many children as adults in the group set up a system of equati
xxTIMURxx [149]

Answer:

Therefore there total of 39 children presented in group of people who attended a ball game.

Step-by-step explanation:

Given:

Total people present=52 .

And there are 3 times children as adults

To Find:

No.of Children Present in Group.

Solution:

<em>Consider  'x'  be the children and 'y' be Adults presented in group.</em>

<em />

So there are total of 52 people.

Therefore Equation becomes,

x+y=52.

And also there  are 3 times children presented in group as adults were.

So

Children=3 times adults

i.e.x=3y

Using in above Equation we get ,

x+y=52

3y+y=52

4y=52

y=52/4

y=13

Hence there are 13 adults  presented in group

So ,

No.of Children=x=3y

=3(13)

=39

No.of.Children =39
