Chuck has a gross pay of $815.70. His gross pay will be reduced by:
- Federal tax of $56;
- Social Security tax that is 6.2% of his gross pay;
- Medicare tax that is 1.45% of his gross pay;
- State tax that is 19% of his federal tax.
Let's count:
1. gross pay of $815.70 - 100%,
Social Security tax of $x - 6.2%.
Then
2. gross pay of $815.70 - 100%,
Medicare tax of $y - 1.45%.
Then
3. Federal tax of $56 - 100%,
State tax $z - 19%.
Then
4. Chuck’s gross pay will be reduced by
Partial derivative is derivative over only 1 variable.
here we have 2 variables so it depends on which variable you want to make partial derivative.
case 1.
df/dx = -3y
case 2
df/dy = 5y^4 - 3x
Answer:
The salmon size is less than equal to 10.28 inches represent bottom 25% of all salmon.
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 12.5 inches
Standard Deviation, σ = 3.3
We are given that the distribution of salmon size is a bell shaped distribution that is a normal distribution.
Formula:
We have to find the value of x such that the probability is 0.25
Calculation the value from standard normal z table, we have,
Thus, the salmon size is equal to or less than 10.28 inches, they are considered small and young and represent bottom 25% of all salmon.
In order to find the number of hats, multiply all the choices together, disregarding size:
4 * 4 * 7 <-- 4 styles * 4 stitches * 7 yarns
= 16 * 7 = 112
112 different hats can be made.
