By=x+2, as this is the only equation that shows the relation between 2 variables
Answer:
a
Step-by-step explanation:
The answer would be 61. First, if you are trying to figure out the pattern. You must subtract the
second number with the first then fourth number with the fifth and so
on, you get.
73 minus 66 equals 7.
21 minus 13 equals 8.
XX minus 52 equals x.
20 minus 10 equals 10.
Basing on the pattern of the set of numbers, x will equal 9, To get this you must do 52 and 9 which will equal 61.
Answer:
n = 100 scores from a population with σ = 20
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, the sample means with size n can be approximated to a normal distribution with mean and standard deviation, which is also called standard error, of 
n = 5 scores from a population with σ = 20
n = 5 scores from a population with σ = 80
n = 100 scores from a population with σ = 20
.
This one is the correct answer.
n = 100 scores from a population with σ = 40
.
