The answer is 16.

First of all, you need to divide 4 by 1/4.

4/1 / 1/4 = 1.

15 - 1 + 2

Next, you go from left to right with addition and subtraction, so subtract 1 from 15 first.

15 - 1 = 14

14 + 2

Finally, add 14 and 2.

14 + 2 = 16.

Which answers I should have to answer

Given:

The table of point scored in 5 games.

After game 6, the mean number of points scored per game is 9.

To find:

The points scored by Maya in game 6.

Solution:

Let x be the points scored by Maya in game 6. Then sum of scores in all 6 games is:

$Sum=8+12+10+6+14+x$

$Sum=50+x$

We know that, the formula for mean is:

$\text{Mean}=\dfrac{\text{Sum of all observations}}{\text{Total number of observations}}$

So, the mean number of points scored per game is:

$\text{Mean}=\dfrac{50+x}{6}$

It is given that the mean number of points scored per game is 9.

$\dfrac{50+x}{6}=9$

$50+x=9\times 6$

$x=54-50$

$x=4$

Therefore, the correct option is A.

What is one-fourth of four sevenths

AlekseyPX

1/4 x 4/7
do the top numbers first. 1 x 4 is 4do bottom numbers next 4 x 7 is 28

that leaves you with 4/28. But you have to reduce.

4/28 = 2/14 = 1/7 (notice I just cut both the top and bottom numbers in half each time I reduced until I couldn't reduce any more).
So, final answer is 1/7
