Find the height of a triangle with area = 110 ft squared and base = 10ft
maria [59]
Well to find the are of a triangle is like finding the are of a rectangle but in half so multiply 110 by 2 to get the original answer before it was divided by 2:

110×2=220

now we need to find out how many 10 are in 220:

220÷10=22

so the height of the triangle would be 22 ft

hope this helped

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
