Answer:

7

Step-by-step explanation:

Given : Numbers : 2.81 and 3.72

To Find : to estimate 2.81+3.72

Solution :

If the value after decimal is 5 or more than round off it to successive whole number other wise round off it to preceding whole number

So, estimate of 2.81 is 3

Estimate of 3.72 = 4

Now =3+4

=7

Hence 2.81+3.72=7

MakcuM [25]

The ages of the Stars are the most dispersed from the team’s mean

<h3> Which statement is right?</h3>

Standard deviation is one way to measure the average of the data by determining the spread of the data. It actually explains how much the observation points are further away from the mean of the data.

Higher the standard deviation, higher the spread of the data and higher is the uncertainty. This means that the team with the highest standard deviation will have the most dispersion.

In this case, the standard deviation of 4.1 is the largest number, therefore, the statement "The ages of the Stars are the most dispersed from the team’s mean." is true

To know more about standard deviation follow

C(x) = mx + 500
grin007 [14]

Total cost as the function of shirts is :

C(x) = mx + 500 .

It is given that , The total cost to produce 100 shirts is $800.

800 = 100m + 500

m = 3

So , cost is given by :

C(x) = 3x + 500 .

Now , putting x = 1000 .

We get :

C(x) = 3x + 500

C(x) = 3(1000) + 500

C(x) = $3500

Therefore , cost of producing 1000 shirts is $3500 .

Hence, this is the required solution .

Yes: the variable K would equal "6"

Step-by-step explanation:

After you set you equation up, you have to isolate the given variable. To do that you have to do the recipriocal (6k-multiplying) which would be division. You would divide k = 36 ÷ 6 . that isolates the variable ,which you would then solve. k = 6 .
