<h2>Answer</h2>
It will take Carl 1.76 minutes to run 1.5 laps
<h2>Explanation</h2>We know from our problem that Chris runs a lap in 1.17 minutes, so he will run half a lap in half the time: minutes.
We have the time it takes Chris to run 1 lap and the time it takes him to run half (0.5) laps, so, to find how long it takes him to run 1.5 laps, we just need to add the two times:
Total time = 1.17 minutes + 0.585 minutes
Total time= 1.755
Since we need to round to two places, we check if the number after the 2nd place is 5 or bigger; if it is, we add 1 to the number on the 2nd place. The number after the 2nd place is 5, so we add 1 to the 5 in the 2nd place to get:
Total time = 1.76 minutes
Carl will run 1.5 laps in 1.76 minutes

Answer: 0.022
Step-by-step explanation:
Let p be the population proportion of horses were fed mostly alfalfa.
We are given that :
, since alternative hypothesis (
) is right tailed , so the test is a right-tailed test.
Also, we have
Sample size= 62
Sample proportion=
Test statistic for population proportion:-
Substitute all values ,
P-value for right tailed test :
P(z>2.01)=1-P(z<2.01) [∵P(Z>z=1-P(Z<z))]
=1-0.9777844 [By using z-value table]
=0.0222156≈0.022
Hence, the P-value for this test is <u>0.022</u> .
