The leg of a right triangle is 3 units and the hypotenuse is 11 units. what is the length, in units, of the other leg of the triangle? (4 points)

ANSWER:

Length of the third side of right triangle is

SOLUTION:

Given, two sides of a right triangle is 3 units and 11 units.

We need to find the length of third side.

Let, length of first side be “a”  i.e. a = 3

Length of hypotenuse be “h” i.e. h = 11

Length of second side be “b” and b =?

We know that, for a right angle triangle,  

hence, length of the third side of right triangle is

the 3rd on is correct

step-by-step explanation:

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.
