Answer:
25 dimes & 12 nickels
Step-by-step explanation:
Let there be "n" nickels and "d" dimes
Total, there are 37 of them, so we can write:
n + d = 37
Also, valueof nickel is 0.05 and value of dime is 0.10 (in dollars) and total value of these 37 coins is 3.10, so we can write:
0.05n + 0.10d = 3.10
Now we can write first equation as:
n + d = 37
n = 37 - d
Replace this into equation 2 and solve for d:
0.05n + 0.10d = 3.10
0.05(37 - d) + 0.10d = 3.10
1.85 - 0.05d + 0.10d = 3.10
0.05d = 3.10 - 1.85
0.05d = 1.25
d = 1.25/0.05
d = 25
Now, n = 37 - d, n = 37 - 25 = 12
So,
There are 25 dimes & 12 nickels
Given:
Gross income : 215
FICA tax : 29.33
Income tax : 29.33
State tax : 2%
City tax : 1%
Retirement fund : 3%
State tax = 215 * 2% = 4.30
City tax = 215 * 1% = 2.15
Retirement Fund: 215 * 3% = 6.45
Net Income = 215 - (15.16 + 29.33 + 4.30 + 2.15 + 6.45)
N.I. = 215 - 59.39
N.I = 157.61 Choice D.
<span>First we calculate z using the formula:
z = (x - μ)/σ</span>
Where:
x = our variable, 10
μ = mean, 8
σ = standard dev, 2
Substituting known
values:<span>
z = (10 - 8)/2
z = 2/2
z = 1
Using the tables of
the normal distribution to find the p-value with z = 1
p = 0.8413
Since we want
"greater than 10”, we need to subtract the probability from 1
therefore
p* = 1 - 0.8413 = <span>0.1587</span></span>
Answer:
n = 23
23 minutes to walk to his friends house
Step-by-step explanation:
If Walter walks there 8 times, and it takes him 184 minutes, you have to divide 184 by 8. You will get 23 which is your answer.
