Answer:
P(more than 2 don't show up)=0.2031
Step-by-step explanation:
Multiplication rule for independent events:
If two events A and B are independent then the multiplication rule state that:
P(A and B)= P(A) x P(B)
Find the probability that more than two do not show up:
The probability that the reservations at the restaurant do not show up is 0.20 (=20%) and there were 8 reservations.
P(more than 2 don't show up)= 1- P(less than or equal to 2 don't show up)
= 1-( P(none show up) +P(one don't show up)+P(two don't show up)
=1- ((0.8⁸) +₈ C₁ (0.2¹)x(0.8⁷) +₈ C₂ (0.2²)x(0.8⁶)
=1- (0.1678 +0.3355+0.2936)= 1-0.7969
P(more than 2 don't show up)=0.2031
Answer:
17b = w
Step-by-step explanation:
17 times the number of bottles = the number of ounces of water
Then you just plug in the numbers you are given
17(51) = w
17 x 51 = 867
<u>51 bottles of water holds 867 ounces</u>
<u />
17b = (51)
divide both sides by 17
51/17 = 3
b = 3
<u>It would take 3 bottles of water to hold 51 ounces</u>

Answer:
(4.5,-6)
Step-by-step explanation:
6x = 27
x = 27/6=4.5
9-3y = 27
-3y = 18
y = -6
