In a statistics course, a linear regression equation was computed to predict the final-exam score from the score on the first te
Elanso [62]

Answer:

Predicted final score of Josh = 62.5

Step-by-step explanation:

The linear regression relationship has been established between the final-exam score and  the score on the first test

The relation ship is represented by a linear equation -

y = 10 + 0.75 x\\

Where

x= score on the first test

Y= final-exam score

Substituting the value of x in above equation we will get -

Y = 10 + 0.75 * 70\\Y = 10 + 52.5\\Y = 62.5

Predicted final score of Josh = 62.5

TiliK225 [7]

Answer:

if your looking for x then

Step-by-step explanation:

first add in the y by doing 10x+5(2x-3)=15 then 10x+10x-15=15 then 20x-15=15 then 20x=30 then divided by 20 for both sides which gets you x=30/20 or 1 1/3

Find the value of x to the nearest tenth.
vladimir1956 [14]

Answer:

The answer to your question is  x = 14.7  

Step-by-step explanation:

Data

∠A = 20°

∠B = 46

a = 7

b = x

Process

To solve this problem use, the law of sines. This law states that the ratio of a side of a triangle to the sine of the opposite angle is the same for all three sides.

The law of sines for this problem is

                   x / sin 46 = 7 / sin 20

-Solve for x

                          x = 7 sin 46 / sin 20

-Simplification

                          x = 7 (0.719) / 0.342

                          x = 5.035/0.342

-Result

                         x = 14.7
