Suppose that shoe sizes of American women have a bell-shaped distribution with a mean of 8.33 and a standard deviation of 1.5. U

never [62]

"97.5" will be the American women's % having their shoe sizes that are no more than 11.33.

Given values are:

Mean = 8.33
Standard deviation = 1.5

Now,

= $8.33 + 2\times 1.5$

= $11.33$ (2 above Standard deviation)

→ The data values are between 8.33 and 11.33,

= $\frac{95}{2}$

= $47.5$ (%)

→ The data value below 11.33,

= $50$ (%)

hence,

→ The percentage of American women will be:

= $50+47.5$

= $97.5$ (%)

Thus the above answer is appropriate.

5 x 2 x (-4) + 6 divided by 2 43 -37 -23 -17

Eva8 [605]

There is a certain order that we follow in doing any mathematical operation:
First we get rid of any operation within brackets, then we do multiplication and divisions and finally we do additions and subtractions.

We need to evaluate: 5x2x(-4) + 6:
So since we have no operations within brackets, then we will do the multiplications first (in their order) then the addition:
5x2x(-4)+6 = 10x(-4)+6 = -40+6 = -34

Now, we need to divide -34 by 2:
-34/2 = -17

The answer is: -17
