Exams are approaching and Helen is allocating time to studying for exams. She feels that with the appropriate amount of studying

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

Carlie runs two different business. She needs to pay $100 for materials, and pay her associates $12 per hour for

Marrrta [24]

Answer:

$375+12ct_c+10lt_l$

Step-by-step explanation:

Carlie is running two different business.

She needs to pay:

- For the childcare business,

100$ for the materials

12$ per hour for each associate for her childcare business, so if we call:

$t_c$ = the number of hours worked by each associate

$c$ = the number of associates

The total cost for the childcare business is:

$C=100+12ct_c$ (1)

- For the lawn care business,

275$ for the materials

10$ per hour for each associate for her lawn care business, so if we call:

$t_l$ = the number of hours worked by each associate

$l$ = the number of associates

The total cost for the lawn care business is:

$L=275+10lt_l$ (2)

Therefore, the total expenses from both businesses is the sum of (1) and (2):

$T=C+L=100+12ct_c+275+10lt_l = 375+12ct_c+10lt_l$

rjkz [21]

<span>An oblong box has a volume equal to lwh, where l is the length, w is the width, and h is the height. If the volume is 24 cubic feet, solve for the height in terms of the other sides.

Given:
volume of 24 cubic feet

Required:
height

Solution:
V = 24 cubic feet
assume that the length, weight and height of the box are all equal
so l = w = h

24 = l^3
l = 2.88 feet</span>
