Answer:
4n-1
Step-by-step explanation:
Diffrence bweetween each number, 3 and -1, -1 and -5, -5 and -9 is 4
4n
find the closest numbers
4*1=4
4*0=0
4*-1=-4
4*-2=-8
now we figure out how to make these numbers into our terms of this sequence
4n-1
4*1-1=3
4*0-1=-1
4*-1-1=-3
4*-2-1=-9
so the nth term is 4n-1
35 dived by 4 = 8.75 and it's simple math, theres really no explaining i did it mainly in my head, but you can just do latis boxes
I believe it is D. Just ignore the 3 then subtract 2/7 from the 4/7, which is 2/7. Now put the 3 back and you'll have 3 4/7.
Answer:
the mean and standard deviation is 2300 and 100 respectively
Step-by-step explanation:
Given that
Mean = 2300
Standard deviation = 500
let us assume the x be the mean of living space
And, the sample is of 25 homes
We need to find out the mean and the standard deviation
So here mean = 2300
And, the standard deviation
= 500 ÷√25
= 500 ÷ 5
= 100
hence, the mean and standard deviation is 2300 and 100 respectively
