First find the inverse function:
y = -x^2 + 2
y - 2 = -x^2
2 - y = x^2
x = (2 - y)^0.5
Therefore inverse: y = (2 - x)^0.5 [x < 2]
Then simply sub in four random values for x to give your answer (hint, for your x values, use 1, - 2, - 7 and - 14. These should yield nice integer values for y)

Answer:

c) skewed to the right.

Step-by-step explanation:

We need to remember that is a distribution is skewed to the right then we have the following condition satisfied:

$Mode< Median$

And if is skewed to the left then we have:

$Mean$

If the distribution is symmetric we need to satisfy:

$Mean = Median=Mode$

For this case since we have most of the values between 200000 and 500000 when we put atypical values like 15000000 that would affect the sample mean and on this case the sample mean would larger than the sample median because the median is a robust measure of central tendency not affected by outliers.

So for this special case we can say that the $Mean>Median$ . And probably the median would be higher than the mode so then we can conclude that the best answer for this case would be:

c) skewed to the right.

What is the answer for -7 +4

lianna [129]

Answer:

answer is -3

Step-by-step explanation:

we know -,+ is -. so minus, plus is minus(here minus and plus are the signs given. opposite signs give minus wheras same signs give plus)

so, first we should subtract 7 minus 4 is 3,.

then we should insert the minus because the greater number has the minus sign. ( you should always insert a sign of a greater number after substituting)
