The arm lengths of people are normally distributed with a mean of 64 cm and standard deviation of 4 cm.

a) What is the probability that a chosen person has an arm length greater than 60 cm?

b) What is the probability that a chosen person has an arm length in the range 56 cm to 69 cm.

c) The arm length of 70% of the people are more than x cm. Find the value of x.

Represent the area which illustrates the probability!

$15 each

step-by-step explanation:

$45/3 children= $15 each

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180

40 x 50 = 2000
