Nitella [24]4 years ago

6 0

Answer:

534

Step-by-step explanation:

Given : 6 x 89.

To find: Use properties to find the sum or product

Solution : We have given 6 x 89.

We can write 89 as ( 100 - 11)

So , 6 x ( 100 - 11) .

Using distributive property. a ( b - c ) = a *b - a *c .

6 x 100 - 6 x 11.

600 - 66 .

534

Therefore, 534.

vredina [299]

Answer:

$\bar X= \frac{\sum_{i=1}^n X_i}{n}$

The reason is because we assume that each week have the same weight and replacing we got:

$\bar X= \frac{190+163+327+205}{4}= 221.25$

And the best option would be:

D. 221.25

Step-by-step explanation:

For this case we have the following data given

Week 1 2 3 4

Minutes 190 163 327 205

For this case we can find the mean with the following formula:

$\bar X= \frac{\sum_{i=1}^n X_i}{n}$

The reason is because we assume that each week have the same weight and replacing we got:

$\bar X= \frac{190+163+327+205}{4}= 221.25$

And the best option would be:

D. 221.25
