The ages of the patients in a doctor's surgery are: 27, 13, 16, 20, 41 and 9. Find the mean of this set of data. Another patient has just walked in and their age is 84. What is the mean of the patients now? How many patients are now over this mean age?

The mean is 30 and there are 2 patients over this age.

Step-by-step explanation:

Add up 27+13+16+20+41+9+84=210

Then divide by the amount of numbers "7" so

210/7 is 30.

There are 2 patients over the age of 30.

Make sure that you are correct and do the problem twice.

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
