  <span>Note that the mean (78 +90 +456 +676 + 111+ 381+ 21)/7 = 259 
The differences (in absolute value - we're going to square later so it doesn't matter) between each piece of data and the mean are 
181, 169, 197, 417, 148, 122, 238 
Square each of these and add the results together to obtain 367452 
Now your question depends on whether you want the sample standard deviation or population standard deviation - which you have not specified. In the first case divide by 6. In the second case divide by 7. We get roughly 61242 or 52493. The square root of each yields 247.47 or 229.11 depending on whether you want the sample sd or pop sd. The 4 choices imply you are looking for the latter, so the answer is A.i think</span>

Is the equation below a function? explain<br>d) y2 = x2 + 5​
RoseWind [281]

Answer:

No

Step-by-step explanation:

y^2 = x^2 + 5​

Rewriting

y^2 - x^2 = 5

This is a hyperbola

We can use the vertical line test to show that it is not a function since a vertical line passes through more than one point.

Kaira's gross pay is $4,633. Her deductions total $1,009.13. What percent of hergross pay is take-home pay?Round to the nearest
Delvig [45]

Answer:

\text{ 78\%}

Explanation:

Here, we want to get the percentage of the gross pay is the take-home pay

Mathematically, we have to divide the take-home pay by the gross pay and multiply it by 100%

Her take-home pay is the difference between her gross pay and her deductions

We have this as:

\text{ 4633 - 1009.13 = \$3,623.87}

We have this as:

\frac{3623.87}{4633}\text{ }\times\text{ 100 \% = 78\%}
