The ages of members of a bowling league are normally distributed with a mean of 43 years and a standard deviation of 4 years. there are 200 members in the league.

About how many members are expected to be between 35 years old and 51 years old?

136
160
183
190​

35  is  2 standard deviations BELOW the mean of 43

51  is  2 standard deviations ABOVE the mean of 43

find z - score for + 2 S.D.     then subtract the z-score for  - 2 S.D.    

  This is the percentage ( in decimal form)    of 200 members between the ages of 35 and 51        Can you finish?

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

step-by-step explanation:

divide, then simplify your answer.

1. make -15.66 ÷   5.8 a fraction. then divide.

2. simplify.  

3. final answer.
