A particular fruit's weights are normally distributed, with a mean of 405 grams and a standard deviation of 19 grams. If a fruit
cluponka [151]

Answer:

413.126

Step-by-step explanation:

Given a normal distribution :

Mean (m) = 405

Standard deviation (s) = 19

Weight of fruit will be greater than how many grams (x) if picked 17% of the time:

P(Z > x) = 0.17 ;

The Zscore for P(Z > x) = 0.17 equals 0.954 (Z probability calculator)

Zscore = (x - m) / s

0.954 = (x - 405) / 19

0.954 * 19 = x - 405

18.126 = x - 405

x = 18.126 + 405

x = 423.126

Weight will be greater than 423.126

Find the area of a regular hexagon with a said length of 10 centimeters and a apothem of 5 spuare root 3
erma4kov [3.2K]

Answer:

C

Step-by-step explanation:

the area (A) of the hexagon can be calculated as

A = \frac{1}{2} pa ( p is the perimeter and a the apothem )

p = 6 × 10 = 60 and a = 5\sqrt{3} , then

A = \frac{1}{2} × 60 × 5\sqrt{3}

   = 30 × 5\sqrt{3}

   = 150\sqrt{3}

   ≈ 259.8 cm² ( to the nearest tenth )
