I think correct answer if d
I think it is 8/17...
hope this helps!
The LinReg line of best fit for this data set is ŷ = -1.24X + 0.66
<h3>What is regression line?</h3>
A linear regression line has an equation of the form Y = a + bX, where X is the explanatory variable and Y is the dependent variable.
Given:
(−5, 6.3),
(−4, 5.6),
(−3, 4.8),
(−2, 3.1),
(−1, 2.5),
(0, 1.0),
(1, −1.4)
Sum of X = -14
Sum of Y = 21.9
Mean X = -2
Mean Y = 3.1286
Sum of squares (SSX) = 28
Sum of products (SP) = -34.6
Regression Equation,
ŷ = bX + a
b = SP/SSX = -34.6/28 = -1.23571
a = MY - bMX = 3.13 - (-1.24*-2) = 0.65714
ŷ = -1.23571X + 0.65714
ŷ = -1.24X + 0.66

Answer:
185 miles
Step-by-step explanation:
We are given that
Both Kyle and Tyler traveled total distance to the beach=425 miles
Kyle traveled distance to the beach=240 miles.
We have to find the distance traveled by Tyler.
To find the distance traveled by Tyler we will subtract distance traveled by Kyle form total distance traveled by together Kyle and Tyler.
Let x be the distance traveled by Tyler.
According to question

miles
Hence, Tyler travels distance to the beach=185 miles
A = 1/2 h(b + x)
2a = h(b + x)
2a/h = b + x
x = 2a/h - b
