Answer:
750kmph
Step-by-step explanation:
Average is sum of all parts divided by the number of parts.
Let Stot be average speed for total trip (800kmph).
Let S1 be speed for first quarter of trip (950kmph).
Let S2, S3, and S4 be the speeds of each of the remaining quarters respectively.
Let Sans be the average speed for the remaining three quarters of the trip (a.k.a. The Answer!).
Stot = (S1 + S2 + S3 + S4) / 4
800kmph = (950kmph + S2 + S3 + S4) / 4
3200kmph = 950kmph + S2 + S3 + S4
3200kmph - 950kmph = 2250kmph = S2 + S3 + S4
Divide both sides by 3.
2250kmph / 3 = (S2 + S3 + S4) / 3 = Sans
Sans = 750kmph
Answer:
2c+5
Step-by-step explanation:
Answer:
10
Step-by-step explanation:
Answer:
No.
Step-by-step explanation:
Note that the point:
(x , y) = (2 , 4) -> In which x = 2, and y = 4. Plug in the corresponding numbers to the corresponding variables:
y = 3x
(4) = 3(2)
4 = 3 * 2
4 ≠ 6
Point (2 , 4) does NOT satisfy the equation.

Answer:
Dependent variable
Step-by-step explanation:
The outcome variable (usually Y) in a regression analysis is called the ________.
c) dependent variable
If there are two variables and there is a linear correlation between them we try to find the regression line by using least squares method.
X the variable which is input or which is first found out is called independent variable.
The outcome variable is the dependent variable
Dummy variable is one which takes only values 0 or 1 depending on whether not present or present.
