Answer:
Probability that Caroline buys fruit, a CD or both is 0.76.
Step-by-step explanation:
Let event A = Caroline buys fruit, event B = Caroline buys CD, Ac and Bc are complementary events.
Events AB, ABc, AcB and AcBc are jointly exhaustive and disjoint, hence P(AB) + P(ABc) + P(AcB) +P(AcBc) =1.
Events A and B independent, hence Ac and Bc independent too and probability P(AcBc) = P(Ac)*P(Bc) = (1 - P(A))(1-P(B)) = 0.6*0.4 = 0.24.
Required probability P(AB + ABc + AcB ) = P(AB) + P(ABc) + P(AcB) = 1- P(AcBc) = 1 - 0.24 = 0.76.
Answer:
What grade of math is this?
Step-by-step explanation:
Answer: option d is correct .
Step-by-step explanation:
In order to find the same attendance we set both equation equal
8x+191 = -x^2+26x+126
simplifying equation ,we get
x^2 -18x+65=0
(x-5) (x-13) = 0
x =5 or x =13
therefore on 5th day and 13th day both plays attendance is same
and it is obtained by plugging x = 5 in and x =13 in either of the equation.
for x = 5 ,
y = 8(5) +191 = 40+191 = 231
for x = 13
y = 8(13)+191
= 104+191
= 295
therefore option d is correct
Answer:
linear
Step-by-step explanation:
The graph would be linear since it's .05 every minute, which would mean that every minute it would cost .05 --> adding up minutes. The flat fee at the beginning is trying to trick you up, don't get fooled ;)
