Answer: 1 11/16
Step-by-step explanation:
5 divided by 5 is 1 so that’s a whole number and 11 is left 16-5=11 so the fraction will be the mixed number as 1 11/16. And also if you can, can you plz help me on my science hw it’s due tomorrow and I don’t know what to do!
Answer: 125
Step-by-step explanation:
4/25 = 20/Y
Cross multiply to get the equation
4Y = 500
Divide both sides by 4
Y=125
Answer: d=5
Step-by-step explanation:
Arithmetic progression
An=a1+d(n-1)
An= nth term
A1= first term
D= common difference
N= nth position
We are given the 4th and 7th terms
For 4th term,n=4
A4=a1+d(4-1)
A4= 16
16= a1+d(4-1)
16= a1+3d........equation 1
For the 7th term,n=7
A7=a1+d(7-1)
A7= 31
31=a1+6d......equation 2
Bring them together
16=a1+3d
31=a1+6d
Subtract equation 1 from 2
So we have
15=3d
D=15/3
D=5
Therefore, the common difference is 5
_____ is a measure of dispersion that indicates how much scores in a sample vary around the mean of the sample.
Answer: Standard deviation is a measure of dispersion that indicates how much scores in a sample vary around the mean of the sample.
