Answer:
80% Confidence interval: (0.4603,0.7397)
Step-by-step explanation:
We are given the following in the question:
Sample mean,
= MD = 0.60 points
Sample size, n = 9
Sample variance = 0.09
Sample standard Deviation =
![=\sqrt{\text{Sample Variance}} = \sqrt{0.09} = 0.3](https://tex.z-dn.net/?f=%3D%5Csqrt%7B%5Ctext%7BSample%20Variance%7D%7D%20%3D%20%5Csqrt%7B0.09%7D%20%3D%200.3)
80% Confidence interval:
Putting the values, we get,
Answer:
The answer to this is 3x+8
Answer:
a. 4 and 120. b. 260 miles. c. 140 miles.
Step-by-step explanation:
d(t) = 400-70t.
a. (4,120) refers that with t=4 (when the driver has driven 4 hours), he is incorrect: 120 miles from his destination. d(4) = 400-70(4) = 400-280 = 120.
b. After driving 2 hours, that is in t=2, he is d(2)= 400-70(2) = 400-140 = 260 miles from his destination.
c. In his second hour of driving, that is in t=2 he is 260 miles from his destination, so he has driven 140 miles.
