answer:
the mean for this is 27
step-by-step explanation:
all you have to do is add up all of the times
15, 18, 20, 22, 28, 37, 49
which would have given you
189
then you divide that number by how much times were written down
7 would be that number so
189/7 = 27
and this is what it is written in one equation
(15+18+20+22+28+37+49)/7
hope this helps you! :)
Answer:
5002
Step-by-step explanation:
The given series is an arithmetic progression with
a = the first term
d = common difference
n = number of terms
S = the sum of the nth term
Recall that
S = n/2(2a + (n-1)d)
As such,
a = 2
d = 8 -2 = 14 - 8 = 6
n = 41
Hence
S = 41/2(2*2 + (41 - 1)6)
= 41/2 ( 4+ 240)
= 41 * 244/2
= 5002
Answer:
496.631579
Step-by-step explanation:
Make a proportion
We know that a 377.44 over a number must equal 76%
377.44/x=76/100
Cross multiply
76x=37,744
Divide by 76 on both sides
x=496.631579
So, 76% of 496.631579 is 377.44
Hope this helps!
