Hello!
To find the dilation factor you find what figure 1 was multiplied by to get figure 2
Hope this helps!
Answer:
The coefficient of variation is 72.66%
Step-by-step explanation:
Data : 3 , 5 , 12 , 3 , 2
We are given that The mean of the sample is 5.
Formula of standard deviation =
Substitute the values :
Coefficient of variation=
Hence The coefficient of variation is 72.66%
Answer: Factorization of 6x + 120 = 6(x+20)
Factors = 6 and x+20
Step-by-step explanation:
Given: The expression 6x + 120 represents the total amount in the account after 6 months.
We need to factor the expression 6x + 120
We can write this as
6 x + 6 (20)
Common factor = 6 in both terms
So, 6 x + 6 (20) = 6(x+20)
Hence, Factorization of 6x + 120 = 6(x+20)
Since it's a sample size, we use x, as the mean and s= standard deviation

Given: x =27, s = 2 and total sample = 32.
Probability that a recruit is at least 31 years old?
Let's calculate the Z score :
_
X - x 31 - 27
Z = ----------- → Z = -------- → Z = 2 (now look up in the Z score table,
s 2
Area (Z=2) =0.9772 , but Z ≥ 2 (at least) , then :
Area (Z≥2) = Area (Z≤ - 2) = 0.0228
P(≥31)= 0.0228
