The area of a triangular sign is 96 ft^2 (96 ft squared). if the base of the sign is 16 feet, what is the height of the sign?

The height of the triangle is 12 feet.

Step-by-step explanation:

The area of a triangle is A = 1/2(b * h).

1/2(b * h) = A

b * h = 2A

h = 2A/b

Now substitute in the variables.

h = 2(96)/(16)

h = 192/16

h = 12

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
