Answer:
<u>The correct answer is C. 20.33%</u>
Step-by-step explanation:
1. Let's review all the information given to us to answer the question correctly.
Mean of time of adults walking a mile = 22 minutes
Standard deviation = 6 minutes
Normal distribution for the walking times
2. What percentage of adults take longer than 27 minutes to walk a mile?
27 minutes = Mean + 5 minutes
27 minutes = Mean + 0.83 * Standard deviation
Using the z table for z = 0.83, we have that:
P (z) = 0.7967
Therefore the probability of adults that take longer than 27 minutes walking a mile is:
1 - 0.7967 = 0.2033
<u>The correct answer is C. 20.33%</u>
Answer:
17
Step-by-step explanation:
Add (4 + 5) = 9 then multiply by 3 = 27 - 12 = 15 +2 = 17
(fog)(4)=f(g(4))= f(4^2 -5)= f(16-5)= f(11)=4•11+1= 44+1=45
Answer:
Step-by-step explanation:
3 red, 1 blue, and 4 yellow...thats a total of 8 marbles
so a red was drawn and not replaced....means we now have 7 marbles.
P(yellow) : since we still have 4 yellow and there are a total of 7 marbles, the probability of drawing a yellow is : 4/7 <==
