I will tell you the answer if you put brainliet
Looks like it should be D since they spent 0.08 on tickets and get 1.92. Then shirts are $55 so we subtract this from the profit.
Fg(x) = 7(3x+1)
= 21x + 7
Answer:
99% CI for the intercept (b₀) [173.29; 1172.01]dollars
Step-by-step explanation:
Hello!
You have the information of two variables
Y: price of a bycicle (dollars)
X: Weight of a bycicle (kilograms)
The estimated regression equation is
^Y= 672.65 - 1.56X
(191.4) (0.28)
Assuming that 191.4 is the estimated standard deviation of the intercept and 0.28 corresponds to the estimated standard deviation of the slope. The statistic you can use to estimate the intercept is a student's t.
99% CI for the intercept (b₀):
b₀ ± tₙ₋₂;1-α * Sb₀
tₙ₋₂;1-α= t₁₄₈;₀.₉₉₅= 2.609
672.65 ± (2.609*191.4)
[173.2874; 1172.0126]dollars
I hope it helps!
Answer: 2h
Explanation:
1) Given: g (x) = 2x + 2, find g (a + h) - g (a)
2) First, replace x by a + h:
g(a + h) = 2 (a + h) + 2 = 2a + 2h + 2
3) Second, replace x by a:
g(a) = 2a + 2
4) Subtract g(a+h) - g(a)
2a + 2h + 2 - (2a + 2) = 2a + 2h + 2 - 2a - 2 = 2h
Answer: 2a
Additional explanation:
This operation is the first step the function known as derivative, since derivative is defined as:
g'(x) = limit when h → 0 of [g( x + h) - g(h)] / h
Since, you have shown that the numerator is 2h, the limit is 2h/h = 2.
And now you know that the derivative of g(x) = 2x + 2 is 2.
