Answer:
answer is a,b,c
Step-by-step explanation:
Subtract 3 from 28 to get 75. Then since 2w symbolizes multiplication you do the opposite, you divide 75 by 2 to get 37.5. So w=37.5
69 cm is one standard deviation below the mean
<span>for a normally distributed (bell curve) population </span>
<span>___ about 68% lie within one standard deviation of the mean ___ 34% above and 34% below </span>
<span>in this case , the 34% below the mean is added to the 50% above the mean (the 1/2 of the population equal to or longer than 79 cm) </span>
<span>so 84% of the population is longer than 69 cm</span>
