Answer:
Regression Line is given by,
y = 22.909 + 0.209 x
The course grade of a student in the course who spent an average of 103 minutes in the course each week is: 22.909 + 0.209 × 103 = 44.436
Step-by-step explanation:
The equation of Regression equation is of the form of:
y = a + bx
where, a is intercept and b is slope
The formula for a and b is given by,
Here, ∑X = 1149.8, ∑Y = 377.2, ∑XY = 93115.95, ∑X² = 320246.72
Thus, a = 22.909
and b = 0.209
Thus, Regression Line is given by,
y = 22.909 + 0.209 x
Thus, The course grade of a student in the course who spent an average of 103 minutes in the course each week is: 22.909 + 0.209 × 103 = 44.436
Now plotting these line:
Answer:
{-1, -2, -3, -4}
Step-by-step explanation:
The domain is the set of all x-values.
Answer:
b = -1
Step-by-step explanation:
7(3b-1): 7 goes into the numbers by multiplying. This will give you 21b-7.
So now the equation should be like 21b-7=2b-26.
-7 and 2b swap places, making 21b-2b=7-26. It will give you 19b= -19.
Finally divide the two numbers (-19 / 19) and the solution will be b= -1.

Answer:
Bachelor's Degree in writing
Step-by-step explanation:
Two ways to find.
1. Find n Natural numbers that 136/n gives reminder 8. and check with 200. Bad Way.
2. Logic way. ... Find Greatest common divisor of 200+8 and 136+8. GCD(208;144)=(64;144)=(64;80)=(64;16). 64 is divisible by 16 so 16 is the answer . check 200/16 reminder 8 so 136/8
