PLEASE ANSWER FAST ITS DUE IN 25 The hair length of students in a class are normal distributed with a
mean of 7 inches and standard deviation of 1.5 inches.
5) What is the probability that a random student will have hair longer than 8.5 inches?
6) What is the probability that their hair will be longer than 2.5 inches?
7) If there are 35 students in class, about how many have hair length longer than 4 inches? (Round
down to the nearest person)
8) Using the same amount of students, about how many have hair lengths between 5.5 and 11.5
inches? (Round down to the nearest person)

answer:  

step-by-step explanation:

odd numbers are only divisible by 1 and itself.

even numbers are divisible by more than 1 and itself.

for example 6 is even because it is divisible by more than 1 and its self. 1 x 6= 6 ; 2 x 3= 6

and 7 is odd because only 7 x 1 equals seveb

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
