Gerard concluded that the triangle with sides StartRoot 95 EndRoot feet, 8 feet, and StartRoot 150 EndRoot cannot be used as a building frame support on the house because it is not a right triangle. How did Gerard come to that conclusion? Explain. ANSWER: Gerard came to that conclusion because 95 + 8 equals 159. In order for the triangle to be a right triangle the sum of the two shorter lengths must equal the length of the hypotenuse. 150 does not equal 159.

Step-by-step e150 - 95 = 55 - 8 = 47 + 95 = 142 + 8 = 150xplanation:

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.
