Fill in the blanks in the photo below.

Step-by-step explanation:

The scatter plot is a plot of amount spent on entertainment(in dollars) against the number of hours worked. The equation of the line of best fit is given as

y = 0.6x + 21.82

This equation gives the predicted amount spent on entertainment while the table gives the exact amount spent on entertainment.

1) when the number of hours worked is 7.8,

The observed amount is $33.50

The predicted amount is y = 0.6 × 7.8 + 21.82 = $26.5

The residual is 33.5 - 26.5 = $7

2) when the number of hours worked is 10.2,

The observed amount is $21.5

Approximately 22

The predicted amount is y = 0.6 × 10.2 + 21.82 = $27.94

Approximately $28

The residual is 22 - 28 = $6

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
