svp [43]

Answer: 0.05

Step-by-step explanation:

Let M = Event of getting an A in Marketing class.

S = Event of getting an A in Spanish class,

i.e. P(M) = 0.80 , P(S) = 0.60 and P(M∩S)=0.45

Required probability = P(neither M nor S)

= P(M'∩S')

= P(M∪S)'                                 [∵P(A'∩B')=P(A∪B)']

=1- P(M∪S)                               [∵P(A')=1-P(A)]

= 1- (P(M)+P(S)- P(M∩S))   [∵P(A∪B)=P(A)+P(B)-P(A∩B)]

= 1- (0.80+0.60-0.45)

= 1- 0.95

= 0.05

hence, the probability that Helen does not get an A in either class= 0.05

Given f(x) = 70 + 11x, find x when f(x) =158
Mumz [18]

Answer:

\huge  \boxed{x = 8}

Step-by-step explanation:

f(x) = 70 + 11x

To find the value of x when f(x) =158 , equate f(x) to 158

We have

70 + 11x = 158 \\ 11x = 158 - 70 \\ 11x = 88

Divide both sides by 11

\frac{11x}{11}  =  \frac{88}{11}  \\

We have the final answer as

<h3>x = 8</h3>

Hope this helps you
