Answer: Stephen's net income is $921.71
Step-by-step explanation:
Hi, to answer this question, first, we have to multiply the amount of hours worked (112) by 11 (because he earns $11 per hour)
Mathematically speaking:
112 x 11 = $1,232
Now we have to sum the federal income tax ($216.05),Social Security ($76.38), and Medicare ($17.86) to obtain the total expenditures:
Total expenditures: $216.05 +$76.38 +$17.86 = $310.29
Finally we subtract the total expenditures ($310.29) to Stephen's revenue ($1,232) to obtain Stephen's net income.
Net income = 1,232 - 310.29 =921.71
Stephen's net income is $921.71
Answer: Distributive property of the multiplication.
Step-by-step explanation:
You did not post Gretchen's expression, but i gues that it is 3*(x + y)
I guess that it is the distributive property of the multiplication.
For 3 numbers, A, B and C, we have that:
A*(B + C) = A*B + A*C
here we have:
3*x + 3*y
We can do the inverse process to the distributive property, and get:
3*x + 3*y = 3*(x + y)
which i guess is Gretchen's expression.
Answer: 2. 1/8
1/4+1/8=3/8
3/8+1/8=4/8=1/2
Answer:
25/784
Step-by-step explanation:
Answer: 8/9
Step-by-step explanation:
Taking the probability as
AA = 4/9 AB = 2/9 BA = 2/9 BB = 1/9
These spaces AA,AB,BA,BB is indicates who wins each game.
There is a 2/3 probability that A will win any particular game.
But considering that these events are independent events, the probability that A wins both games is 2/3 and 2/3 which equals to 4/9.
Therefore the probability that A wins at least one match would be 1 − P(BB).
And this gives 1 - (1/9) =
8/9
