Suppose you were looking at the histogram of the incomes of all of the households in the United States. Do you think that the histogram would be bell shaped? Skewed to the left or right?

The histogram is right-skewed.

Step-by-step explanation:

The income of all households in the United States can be categorized as low, medium and high.

Not many people earn a high income. So the proportions of people decreases as the income increases.

Most of the people earn a medium income. So the mode of the data would be somewhere in the start of the the distribution.

There are many households that earn a low income. But this proportion is not more than the proportion of people earning low income.

So the histogram for income distribution will have a long right tail with maximum data at the starting point.

This implies that the histogram is right-skewed.

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
