Drupady [299]3 years ago

Step-by-step explanation:

I am not allowed to answer more than 3 questions. So I will do the first 3.

15a. i) (2/3) = 4/9

ii) (2/3) = 8/27

iii) (2/3) = 16/81

b. The product is small because you are finding the fraction of a fraction.

16. Compared to the factors, the product is less than each fraction. This is because, as stated above, you are trying to find a fraction (a part of the whole) of another fraction. When you multiply a whole number by a fraction, the whole number decreases. The same applies to a fraction.

17a. 0.4 × 0.3 = 0.12

b. 0.4 = 4/10 = 2/5

0.3 = 3/10

3/10 × 2/5 = 6/50

Tresset [83]

Answer:

They went over their goal for the last six months by 34 minutes per month.

Step-by-step explanation:

Mean of a data-set:

The mean of a data-set is the sum of all values in the data-set divided by the size of the data-set.

529, 499, 651, 652, 1,163, and 310 minutes on their cell phone plan.

The mean is:

$M = \frac{529+499+651+652+1163+310}{6} = 634$

By how many minutes did they go over their goal in the last six months?

The mean was of 634 minutes, and they wanted to keep it below 600. So

634 - 600 = 34

They went over their goal for the last six months by 34 minutes per month.

The midpoint formula is:
(point1 + point2)/2

1) (-2 + 12)/2 = 5

2) (-1 +5)/2 = 2
    (0+2)/2 = 1
     (2,1)

3) Sqrt of (x2-x1)^2 + (y2 - y1)^2
     sqrt of (7 -1)^2 + (-7 - 1)^2
     sqrt of (6)^2 + (-8)^2
     sqrt of 36 + 64
     sqrt of 100
     10

Hope this helps!
