Answer:
We get that the heaviest of fruits weigh 766.84 grams.
Step-by-step explanation:
We know that a particular fruit's weights are normally distributed, with a mean of 738 grams and a standard deviation of 14 grams.
We have:

We calculate x:

We use the standard normal table and we get: Z=2.06.
So, we get

Answer:
11 meters is her approximate reaction distance.
Step-by-step explanation:
Speed of the car of Mindy = 32 mile/hour = 
1 mile = 1609.34 m
1 hour = 3600 seconds
Duration for her reaction last after student runs into street in front of her = 
Distance covered three -quarters of a second = d

d = 10.73 m ≈ 11 m
11 meters is her approximate reaction distance.
