Sav [38]

Answer:

The correct answer is - 3, 4, and 5.

Step-by-step explanation:

Given:

distance = 5 miles

time to cover 5 miles = 10 minutes

If his claim is true then,

additional Distance = 15 miles

total distance will be = 15+5 = 20 miles

additional time = 30 minutes

total time = 10+30 = 40 minutes

Solution:

The speed of the vehicle can be calculated by the formula:

V = d/t

where V is speed or velocity

d = distance

t = time

Putting the final or total values in formula =

V = 20/40

= 1/2 (5th statement is true)

In an hour where 60 minutes are there, 1/2 = 30 miles per hour.

Thus, 3rd and 4th statement are true.

laila [671]

Answer: 756

Step-by-step explanation:

Given : The proportion of adults over 50 never graduated from high school.  = 0.23

Margin of error : E=0.03

Significance level : \alpha=1-0.95=0.05

Critical value : z_{\alpha/2}=1.96

The formula to find the sample size is given by:_

n=p(1-p)(\dfrac{z_{\alpha/2}\ }{E})^2

i.e. n=(0.23)(0.77)(\dfrac{(1.96)}{0.03})^2=755.941511111approx756

Hence, the required minimum sample size = 756
