Answer:
C
Step-by-step explanation:
If the average wasn't shifted at all, that means the third value must've been the same as the average to not shift it.
<h3>
Answer: 15 years old</h3>
=============================================
Explanation:
m = Maggie's age (some positive whole number)
4m = four times her age
4m-7 = seven years younger than 4m = brother's age
Add up her age (m) and her brother's age (4m-7) to get a sum of 68.
m+(4m-7) = 68
5m-7 = 68
5m = 68+7
5m = 75
m = 75/5
m = 15
Maggie is currently 15 years old.
Her brother is currently 4m-7 = 4*15-7 = 60-7 = 53 years old.
Their current year ages add to: 15+53 = 68 which confirms the answer.
Answer:
I believe the answer would be 50.714 degrees, I'm not sure how they want you to round that though.
Let x be the time she ran and y be the time she walked
then distance ran = 25x and distance walked = 5y
so 15x + 5y = 42
and x + y = 4
* second equn. by -5:-
-5x - 5y = -20
add this to the first equn:0
10x = 22
x = 2.2
distance she ran = 2.2 * 15 = 33 km
Answer:
<h3>
The Option B) Multiple regression is correct</h3><h3>Regression analysis involving one dependent variable and more than one independent variable is known as <u>multiple regression.</u></h3>
Step-by-step explanation:
Given that regression analysis involving one dependent variable and more than one independent variable
For : Regression analysis involving one dependent variable and more than one independent variable is known as <u>multiple regression</u>
- In statistics, a linear regression is a linear relationship between a dependent variable and one or more independent variables.
- In statistics for more than one independent variable and with one dependent variable in regression analysis , then the regression is called as multiple regression.
- Therefore Option B) Multiple regression is correct
<h3>Regression analysis involving one dependent variable and more than one independent variable is known as <u>
multiple regression</u>.</h3>
