Answer:
I b3live it is 50 miles/hour
Step-by-step explanation:
We need to know how many miles he drove from 9:00 to 10:30 so you do 150-75 which is 75. Then, you do 75÷1.5 because 9:00 and 10:30 are an hour and a half apart and then you get 50 mph.
Answer:
L(w) = 8 mm + (2 mm/wk)(wk)
Step-by-step explanation:
L(w) = length of beard as a function of time in weeks
L(w) = 8 mm + (2 mm/wk)(wk)
(1) it can be both exterior of vertex or base. 180-130=50°
vertex is 50°: base=(180-50)/2=65°
base is 50°: vertex= 180-2*50=80°
vertex 50 base 65; vertex 80, base 50
(2)base=180-130=50°
vertex=180-2*50=80°
base 50 vertex 80
Answer:
a) 95% confidence interval for the population proportion of all young adults in Kentucky who received help from their parents.
( 0.0761 , 0.3239)
b) Margin of error = 0.1264.
Step-by-step explanation:
<u>Explanation</u>:-
Given '8' persons in a random sample of 40 young adults who recently purchased a home in Kentucky received help from their parents.
sample proportion of success 
q = 1=p
q = 1-0.2 = 0.8
a)
95% confidence interval for the population proportion of all young adults in Kentucky who received help from their parents.


(0.2 - 0.1239,0.2+0.1239)
( 0.0761 , 0.3239)
b) the margin of error for a 95% confidence interval for the population proportion.
For the 95% confidence interval ∝= 0.05 and zₐ = 1.96≅2.


Margin of error for a 95% confidence interval for the population proportion.
Margin of error = 0.1264.
