Answer: 0.07
Step-by-step explanation: Since it is a binomial experiment , we will use the formula:
n C r 

p = 0.35
q = 1 - 0.35 = 0.65
n is the number of trials = 7
r = 3
substituting into the formula, we have
7 C 3 (

= 35(

=0.0736
to the nearest tenth
= 0.07
Answer:
Step-by-step explanation:
- x( x² - 12x + 21 )
Y - ( - 2) = - 3 ( x - ( - 3 )
This equation can also be simplified to
y + 2 = - 3 ( x + 3 )
