Answer:
The answer is below
Step-by-step explanation:
The mean (μ) = 3.7 m, standard deviation (σ) = 1.17 m, confidence (C) = 95% = 0.95, sample size (n) = 50
a) α = 1 - C = 1 - 0.95 = 0.05
α/2 = 0.05/2 = 0.025
The z score of α/2 is the same as the z score of 0.475 (0.5 - 0.025) which is 1.96. Hence:
The margin of error (E) = 
The confidence interval = μ ± E = 3.7 ± 0.32 = (3.38, 4.02)
b) This means that we are 95% sure that any distance between the taxi and the lead car is between 3.38 m and 4.02 m
Answer:
18
Step-by-step explanation:
f(x) is the ultimate base of all function notation forms
f(h) is the addition of 4(Vertical Shift of 4)
f(h)=2x+10
If f(4), then 2(4)+10
f(4)=18
Answer:
I think its D
Step-by-step explanation:
I said this because 410/8 equals 51.25 and if you multiply that by x (8) you will get 410. Hopefully i got this correct.
1/4 mile in 1/32 hr
unit rate would be x miles in 1 hour.
A complex fraction is a fraction that has a fraction in the numerator OR denominator OR both.
(1/4) / (1/32) =(1/4) * (32/1) = 8 miles in 1 hour
