If 2/5 are apples, 2/5 x 8.9 kilos = 0.4 x 8.9 = 3.56 kilos of apples
pears = 8.9 - 3.56 = 5.34 kilos
if apples are 2/5, then pears are 3/5. 3/5 x 8.9 = .6 x 8.9 = 5.34 kilos of pears
9 cuz 4 times 1/2 is 2 and 2+7=9
Answer:


And the answer for this case would be :
after round the value
Step-by-step explanation:
We have the following data set given:
31, 33, 36, 41, 34
If we want to find the standard deviation we need to find first the sample mean with this formula:

And replacing we got:

Now we can find the sampel deviation with this formula:

And replacing we got:

And the answer for this case would be :
after round the value
You are wrong.
