Answer:
12
Step-by-step explanation:
All you is divisions as followed:
100 ÷ 8 = 12
A = event that you select a black sweater
P(A) = 2/5 since there are 2 black out of 2+3 = 5 total
After you make a selection, we have the event
B = event that you select another black sweater assuming event A has happened already
P(B) = 1/4 because there's 1 black sweater left out of 5-1 = 4 left over
Multiply the probabilities
P(A and B) = P(A)*P(B)
P(A and B) = (2/5)*(1/4)
P(A and B) = 2/20
P(A and B) = 1/10
The answer as a fraction is 1/10
In decimal form, it is 0.1
As a percent, the answer is 10%
Answer:
x=3/7
Step-by-step explanation:
6-2x=3+5x
subtract 5x from both sides
6-2x-5x=3
subtract 6 from both sides
-2x-5x=3-6
add like terms
-7x=-3
divide both sides by -7
x=3/7
4• y because since the brackets are multiplying the dot represents the x
