B I’m pretty sure I think or 826
The answer is 2.7
I’m not an expert at this but i did some research so I hope I can help
It’s 2.7 because the formula for calculating density is to divide the mass by the volume and in you do that for each of them you get 2.7 every time
Let a,b,c,d and e are five numbers
mean = (a +b+ c+ d+e)/5 = 30
⇒ (a +b+ c+ d+e) = 150_______(1)
now, Let the number excluded be a
then, new mean = (b+ c+ d+e)/4 = 28
⇒ (b+ c+ d+e)= 112
putting this value in (1),
⇒a + 112 = 150
⇒a = 150 -112 = 38
excluded number = 38
Answer:
Step-by-step explanation:
Let us represent:
Apple pie = a
Cherry pie = c
Peach pie = p
A bakery has three types of pie: apple, cherry, and peach.
There are four times as many apple pies as peach pies.
a = 4p
