The mean number of words spoken per day by the women was 14,297 with a standard deviation of 6441. Use the 68-95-99.7 rule to describe the distribution of the sample mean number of words spoken per day by women. (Find values between which 68% of the distribution falls, 95% like we’ve done in class)i.1st Deviation- Between 7856 and 20738 (68%) ii.2nd Deviation- Between 1415 and 27179 (95%) iii.3rd Deviation- Between -5026 and 33620 (99.7%)

step-by-step explanation:

5 x 14?

im new, sorry if this is wrong.

step-by-step explanation:

-3

step-by-step explanation:

a drawing really does here:

so i draw the horizontal line y=2 and the vertical line x=-2 at this intersection i put b (this is where my right angle is going to be).   so point b is at (-2,2).   point a is 5 units long and is also on y=2 so this point has to be (3,2) or (-7,2) -doesn't matter i will go with (3,2).

now we know c is at (-2,y) we don't know the y yet bet we know that c is on x=-2.

we have the area of the triangle is .5bh=12.5

we know the base length is 5 (ab)

we have the height is (2-y) if you look at your

plug in

.5(5)(2-y)=12.5

solve for y to get the y-coordinate for c

2.5(2-y)=12.5

divide both sides by 2.5 giving:

2-y=5

now subtract 2 on both sides

-y=3

y=-3

stops on an even number.
