Answer:
95% Confidence interval for taxi fare: ($20.5,$24.2)
Step-by-step explanation:
We are given the following data set: for fares:
$22.10, $23.25, $21.35, $24.50, $21.90, $20.75, and $22.65
Formula:
95% Confidence interval:
Putting the values, we get,
![22.35 \pm 1.96(\frac{2.5}{\sqrt{7}} ) = 22.35 \pm 1.85 = (20.5,24.2)](https://tex.z-dn.net/?f=22.35%20%5Cpm%201.96%28%5Cfrac%7B2.5%7D%7B%5Csqrt%7B7%7D%7D%20%29%20%3D%2022.35%20%5Cpm%201.85%20%3D%20%2820.5%2C24.2%29)
I think the answer is D, 28*11=308 plus the 12*14 equals 476. The answer is D
Answer:
A) B is greater
B) when C = 21, A = 5 and B = 15
C) A must be 0, 5, or 12 for C to be greater than B
Step-by-step explanation:
A) when a = -3, c = -20 and b = 4(-3)-5 so B = -17
B) when c = 21, a = 5 and b = 4(5)-5 so B = 15
C) C is greater than B when a = 0, 5, and 12
when a = 0, b = 4(0)-5 or -5
when a = 5, b = 4(5)-5 or 15
when a = 12, b = 4(12)-5 or 43
Answer:
5.45 hours.
Step-by-step explanation:
The formula =
P = P0(10)t
In this circumstance, P0 = 275, P = 15,000 and t = ?
Applying the values into the formula:
P = P0(10)t
15,000 = 275 × (10) × t
15,000 = 2750t
t = 15,000/2750
t = 5.45 hours
