A piece of fabric is in the shape of a square. The area measures 50 square inches. Find the length of one side of the piece of fabric. Write your answer in the form A√B

The answer to your question is 5

Step-by-step explanation:

Data

Area = 50 in²

Length = ?

- Formula

Area of a square = L x L or Area = L²

- Substitution

                 50 = L²

- Simplification

                 L = -

- Find the prime factors of 50

                 50  2

                 25  5

                    5 5

                     1

          50 = 2 x 5²

- Express the result as A√B.

                 = 5     Only 5 can be out of the square root.

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.
