Suppose X has a continuous uniform distribution over the interval [2.2, 5.3]. Round your answers to 3 decimal places. (a) Determine the mean of X. 6.4 (b) Determine the variance of X. .801 (c) What is P(X < 4.0)?

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

x = 12

y = 1

for the points!

2 1/2 feet

step-by-step explanation:

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
