A particular fruit's weights are normally distributed, with a mean of 738 grams and a standard deviation of 14 grams. The heavie

posledela

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:

$\mu=738\\\\\sigma=14$

We calculate x:

$P(X$

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

So, we get

$2.06=\frac{x-738}{14}\\\\x-738=28.84\\\\x=766.84$

We get that the heaviest of fruits weigh 766.84 grams.

Mindy is driving 32mi / h as she nears an elementary school. A first grade student runs into the street after a soccer ball, and

kifflom [539]

Answer:

11 meters is her approximate reaction distance.

Step-by-step explanation:

Speed of the car of Mindy = 32 mile/hour = $\frac{32\times 1609.34 m}{3600 s}$

1 mile = 1609.34 m

1 hour = 3600 seconds

Duration for her reaction last after student runs into street in front of her = $\frac{3}{4} seconds$

Distance covered three -quarters of a second = d

$d=\frac{32\times 1609.34 m}{3600 s}\times \frac{3}{4} s$

d = 10.73 m ≈ 11 m

11 meters is her approximate reaction distance.
