Answer:
0.6125
Step-by-step explanation:
We have,
P(ripe avocados) = 0.45 , n = 5
by binomial distribution,
P(x=k) = 
P(2 ≤ x ≤ 3) = P(x=2) + P(x=3)
P(x=2) = 
= 10 x (0.45)² x (0.55)³
= 0.3369
P(x=3) = 
= 10 x (0.45)³ x (0.55)²
= 0.2756
So, P(2 ≤ x ≤ 3 ) = 0.3369 + 0.2756
= 0.6125
Answer:
I know this! It's 36,000.
Step-by-step explanation:
40+3.50x5=57.50 so you purchased 5 movies for the total of 57.50 at the end of the month
Answer:
x = 6, y = -5.
Step-by-step explanation:
6x + 8y = -4
-6x - 10y = 14 Adding will eliminate the terms in x:
0 - 2y = 10
y = 10/-2 = -5,
Plug this into the second equation:
-6x - 10(-5) = 14
-6x = 14 - 50 = -36
x = -36/-6
x = 6.
