We know that

The residual value is the observed value minus the predicted value.

RESIDUAL VALUE=[OBSERVED VALUE-PREDICTED VALUE]

where

Predicted value.--> the predicted value given the current regression equation

Observed value. --> The observed value for the dependent variable.

in this problem

predicted value for x=3 approximate y=3.6

observed value is for x=3 y=5

RESIDUAL VALUE=[5-3.6]------> 1.4

the answer is

the best estimate of the residual is 1.5

Find the value of x

Svet_ta [14]

Answer:

$150^o$

Step-by-step explanation:

Step 1: Distribute the plus

$(x + 15)^o + (135 - x)^o$

$x + 15 + 135 - x$

Step 2: Combine like terms

$x + 15 + 135 - x$

$(x - x)^o + (15 + 135)^o$

$0 + 150^o$

$150^o$

Answer: $150^o$

A bracelet that normally sells for $30.00 is on sale for $25.50. What is the percent discount?

vekshin1

Answer:

15% off

Step-by-step explanation:

We know we paid $25.50 of the original $30. We can divide these two numbers $\frac{25.5}{30}=0.85$ . This is means we paid 85% of the original price. The discount percentage is the remaining percentage from 85 to 100 which is 15. The pants were 15% off.
