1. Let X be a binomial random variable with n = 20 and p = .3. A. Write the expression for P(x = 6) in terms of the formula
, then
evaluate it using your calculator. (1 point)
B. Using probability notation, P(X = x), write out all the probabilities you'd need to add
up in order to calculate P(X < 6), and then evaluate it using your calculator. (1 point)
C. For part B, why did you choose the upper bound that you did? If you were using the
normal approximation could you choose a different upper bound? Why or why not?
(1 point)

e) none of the above because the measure of angle cba is 101°

x = 23.78

step-by-step explanation:

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

the answer would be d.

step-by-step explanation:

move all variables to the left side and all constants to the right side

(x−3)^2+(y−1)^2=16

this is the form of a circle. use this form to determine the center and radius of the circle.

( x − h ) 2 + ( y − k ) 2 = r 2

match the values in this circle to those of the standard form. the variable   r   represents the radius of the circle,   h   represents the x-offset from the origin, and   k   represents the y-offset from origin.

r = 4

h = 3

k = 1

the center of the circle is found at   ( h , k ) .

center:   ( 3 , 1 )

these values represent the important values for graphing and analyzing a circle.

center:   ( 3 , 1 ).

radius:   4
