Answer = c

Step-by-step explanation:Since the medians are approximately the same they lost on average around the same amount regardless of exercise. Notice that the range of those with exercise is smaller though so they were more consistent in the amount of weight lost.

Estimate the sum by rounding to the nearest whole number 18.74+41.49
satela [25.4K]
Hello!

I'll start w/ 18.74 to round. To round 18.74, the 4 wouldn't have any effect raising the 7's value, since anything 4 and below won't increase the number's value. Now you just have 18.7. The 7 will increase the 8's value to a 9, since anything 5 and up will increase the rounded number's value. So 18.74 is now rounded up to 19.

For 41.49, you'll round the 4 to a 5, since 9 will increase the value of the 4. Now you have 41.5. The newly rounded 5 will then increase the 1's value, making it a 2. So now 41.49 is now rounded up to 42.

You can now estimate the sum by adding 19 w/ 42 to get an estimate of 61!

I hope this helps!!!

A sales person in a stereo store is given a choice of two different compensation plans. One plan offers a weekly salary of $250
snow_tiger [21]

Answer:

<em>The salesperson needs to sell 10 stereos to make the same money on both plans</em>

Step-by-step explanation:

We'll analyze both choices for the compensation plans of a salesperson.

One plan offers a fixed weekly salary of $250 plus a $25 commission for each stereo sold. The function than models this plan is:

P1=250+25x

Where x is the number of stereos sold.

The other plan offers no fixed salary but a $50 commission on each stereo sold. The function of this plan is:

P2=50x

To find the equilibrium point for both plans, we make P1=P2:

250+25x=50x

Simplifying:

25x=250

Solving:

x = 250 / 25 = 10

The salesperson needs to sell 10 stereos to make the same money on both plans
