Answer:

5

Step-by-step explanation:

  1. (4n+5)-n/20=1
  2. cross multiply:(4n+5)-n=20
  3. 4n+5=20+n
  4. 4n-n=20-5
  5. 3n=15
  6. Divide both sides by coefficient of n
  7. n=5

A numerical data set has 9 values. How many of these values does the data
Paraphin [41]
I think it’s D) 9 because when you find the mean of a set of values you are taking into account and adding all of the numbers, and then dividing them by how many numbers there is, so the mean would be summarizing all of them, hope this helps

Can you please help me? Keep it a little basic. (no decimals) Thanks for the help!
Delvig [45]
When you are dividing fractions you just flip the second fraction upside down and multiply the two fractions
So the first is
½ x 6/1 = 6/2 = 3

For the second you write them as improper fractions then do the same
So it is
3/2 / 1/8 = 3/2 x 8/1 = 24/2 = 12

So the answer to the first question is 3 and the second is 12
