Answer: (5, 2.7) residual plot is correct .

Step-by-step explanation:

Given : model the data is y = –0.33x + 4.27.

To find :Which residual plot is correct  (1, 4.0), (2, 3.3), (3, 3.8), (4, 2.6), (5, 2.7).

Solution : We have given that :

                          y = –0.33x + 4.27.

Substitute  x=1 , y =  –0.33(1) + 4.27 = 3.94 incorrect

Substitute  x=2 , y =  –0.33(2) + 4.27 = 3.61 incorrect

Substitute  x=3 , y =  –0.33(3) + 4.27 = 3.28  incorrect

Substitute  x=4 , y =  –0.33(4) + 4.27 = 2.95  incorrect

Substitute  x=5 , y =  –0.33(5) + 4.27 =  2.62 correct

Therefore , (5, 2.7) residual plot is correct .

Using a table of values, determine the solution to the equation below to the nearest fourth of a unit. 2^x=1-3^x
Greeley [361]

Answer:

Option (1)

Step-by-step explanation:

Given equation is,

2^x=1-3^x

To determine the solution of the equation we will substitute the values of 'x' given in the options,

Option (1)

For x = -0.75

2^{-0.75}=1-3^{-0.75}

0.59 = 1 - 0.44

0.59 = 0.56

Since, values on both the sides are approximately same.

Therefore, x = -0.75 will be the answer.

Option (2)

For x = -1.25

2^{-1.25}=1-3^{-1.25}

0.42 = 1 - 0.25

0.42 = 0.75

Which is not true.

Therefore, x = -1.25 is not the answer.

Option (3)

For x = 0.75

2^{0.75}=1-3^{0.75}

1.68 = 1 - 2.28

1.68 = -1.28

Which is not true.

Therefore, x = 0.75 is not the answer.

Option (4)

For x = 1.25

2^{1.25}=1-3^{1.25}

2.38 = 1 - 3.95

2.38 = -2.95

It's not true.

Therefore, x = 1.25 is not the answer.
