============================================================

Explanation:

The info "5 months" is never used to compute the mean. We could easily replace it with "6 months" or "7 months" or any stretch of time, and still get the same answer. So we'll ignore this value.

What we'll do is add up the 21 items given to us, and then divide by 21.

Because there are so many values, and it's easy to get lost, I'm going to add up across the rows

Row One: 256,229+253,657+218,747+246,163+235,626+288,694 = 1,499,116
Row Two: 316,265+196,721+319,620+285,077+215,152+253,291 = 1,586,126
Row Three: 315,011+199,901+265,443+291,806+303,556+215,359 = 159,1076
Row Four: 258,554+293,658+289,935 = 842,147

Those subtotals then add up to this

1,499,116+1,586,126+1,591,076+842,147 = 5,518,465

This is the same as adding up all 21 values.

Finally, we divide that sum over 21 as there are 21 values in this list

(5,518,465)/21 = 262,784.047619048

That value then rounds up to 262,785

If your teacher just wanted things to the nearest whole number (without rounding up), then the answer would be 262,784

Side note: using a spreadsheet program would probably be the most efficient/fastest method for this type of problem.

each statement below describes the transformation of the graph f(x)=x square. which statement correctly describes the graph of g

Vitek1552 [10]

Answer:

The correct option is:

The graph of g(x) is the graph of f(x) translated 7 units up and 7 units right.

Option A is correct option.

Step-by-step explanation:

The parent function is: $f(x)=\sqrt{x}$

The transformed function is: $g(x)=\sqrt{x-7} +7$

We need to find the statement that best describes the transformed function.

We know the transformation rule:

If f(x) is transformed into f(x)+c, then the function is transformed vertically c units up.

If f(x) is transformed into f(x)-c, then the function is transformed vertically c units down.

If f(x) is transformed into f(x-c) then the function is transformed right c units.

If f(x) is transformed into f(x+c) then the function is transformed left c units.

So, In the given transformation:

The parent function is: $f(x)=x^2$

The transformed function is: $g(x)=\sqrt{x-7} +7$

The transformed function is shifted 7 units up $g(x)=\sqrt{x-7} \mathbf{ +7}$ and 7 units right $g(x)=\sqrt{x\mathbf{-7}} +7$

So, The correct option is:

The graph of g(x) is the graph of f(x) translated 7 units up and 7 units right.

Option A is correct option.
