Multiply the bracket by -2
Whenever multiplying a -negative number with a -negative number= + positive number.
(-2)(2b)(-2)(-3)
-4b+6
Answer: -4b+6
Answer:
a. P=0.04
b. P=0.54
c. P=0.96
Step-by-step explanation:
If half of the college graduates are married, then we have:
- 21% are college graduates and married.
- 21% are college graduates and not married.
If 75% of the workers are married, and 21% of the workers are college graduates and married, then (75%-21%)=54% of the workers are not college graduates that are married.
If 25% of the workers are married, and 21% of the workers are college graduates and not married, then (25%-21%)=4% of the workers are not college graduates that are not married.
a) P=0.04 (explanation above)
b) P=0.54
c) In this case, the probability is the complement of point "a". Then we can calculate it by substracting the probability of not being married and not being a college graduate.
P=1-0.04=0.96
Answer:
w = 18
Step-by-step explanation:
6(33 - w) = 90
33 - w = 15
-w = -18
w = 18
Answer:
-12x+16=y
Step-by-step explanation:
Subtract 3 from 11: 8-0.5y=6x
Move 0.5y to the right side: 8=6x+0.5y
Move 6x to the left side: -6x+8=0.5y
Divide both sides by 0.5: -12x+16=y
