Answer:
$10.19
Step-by-step explanation:
We are told:
If the mean of 20 prices is $10.39
We have to find the total price
= Mean × number of prices
= 20 × $10.39
= $207.8
5 of the items with a mean of $10.99 are sampled
We would also find the total price
Mean × Number of samples
$10.99 × 5
= $54.95
what is the mean of the other 15 prices?
We find the total prices of the 15 prices
= Total 20 prices - Total of 5 prices
= $207.8 - $54.95
= $152.85
The mean of the other 15 prices
= $152.85/15
= $10.19
Answer:
The variable that is being predicted is the <u>dependent variable</u>.
Step-by-step explanation:
The regression analysis is used to determine the effect on the response or dependent variable with every one unit change in the predictor or independent variable.
In case of simple linear regression there is only one independent variable and in cases of multiple linear regression there are more than one independent variables.
The general form of simple linear regression is:
The general form of multiple linear regression is:
The dependent variable are usually denoted by the letter "<em>y</em>" and the independent variables are usually denoted by the letter "<em>x</em>".
Thus, the variable that is being predicted is the <u>dependent variable</u>.
First, you must add the total of Monday amd Tuesday
4.32+6.86=11.18
Then you subtract the totals from this week and last week
11.18-7.89=3.29
3.29 rounds to 3.30 aka 3.3 so your answer is C
7x+8 is the equivalent equation
If you graph the equation then one of the point should be on (5,1)
