12 is 9.52380952381% of 126
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:
19 - 4.07
14.93

Hi there!
• Principle amount, P = $ 7, 250
• Rate of interest, r = 12 %
• No. of weeks in an year, n = 52
• Time period, t = 10 years
Aₜ = P [ 1 + (

) ] ᴺ ˣ ᵀ
A₁₀ = 7, 250 [ 1 + (

) ] ⁵² ˣ ¹⁰
Simplifying :-
A₁₀ = $ 24,037.59
Hence,
Option [ 1. ] - $ 24,037.59 is Correct
~ Hope it helps!
