Congratulations, CPhill!!
36+27 = 63
63-20 = 43
60-43 = 17.
17 people took neither.
To figure out this problem, do this...
Look at the number of outcomes for each possibility.
Multiply the numbers.
2*2*2*4 = 32
There are 32 kids lunches possible.
You're welcome, Guest!!
296 = .4n
148 = .2n
Multiply both sides by 5.
740 = n.
There are 740 students in the middle school.
To solve this problem, do this...
Multiply the probabilities of the outcomes. 4/10*6/10 = 24/100 = 12/50 = 6/25.
The answer is 6/25.
The commutative property of multiplication says that a*b = b*a.
Because of this, the answer is the 2nd one.
To simplify this expression, first expand the four terms(in total) in the parantheses. When expanded, you get 14b - 12 - 10b + 15. Simplify this to get 4b + 3.
The simplified expression is 4b+3.
For the first one...
To calculate the first problem, first find the probability of getting one right. That is 1/2. Then, getting three right is the same as 1/8 probability. Likewise, getting three wrong is 1/8 probability. Multiplying these two fractions gets us 1/64 probability.
The probability of Karen getting three questions right and three questions wrong is 1/64.
