Answer: x = 267
Step-by-step explanation: To find x, we need to subtract 500 - 233. This equals 267.
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
Answer:
8
Step-by-step explanation:
(24-12)/1.50=8
Hello, Briana so when dividing fractions, its best to put them in decimal form so that you can divide or multiply better. Now having this in mind, 4.25 divided by 1.5 becomes the new equation and using simple math on a calculator, we can conclude that the answer to this question is 1.7 in decimal form or 1 and 7 over 10 in fraction form. Hope this helped, if you have any questions, please ask!
Answer:
13 =x
z =88
Step-by-step explanation:
7x+1 is a vertical angle to 9x -25
That means they are equal
7x+1 = 9x-25
Subtract 7x from each side
7x-7x+1 = 9x-7x-25
1 = 2x-25
Add 25 to each side
1+25 =2x-25+25
26 = 2x
Divide by 2
26/2 = 2x/2
13 =x
7x+1 and z are supplementary angles, which means they add to 180
7x+1 +z = 180
We know x
7(13) +1 +z = 180
91 +1 +z = 180
92 +z = 180
Subtract 92 from each side
92-92 +z = 180-92
z =88
