Answer:
1, 27, 3, 9,
Step-by-step explanation:
To find the factors of 27 you need to find which whole number times another whole number = 27
We know that 1*27 = 27
We also know that 3*9 = 27
The factors are all the numbers that are used in the multiplication.
In this example the numbers are: 1, 3, 9 and 27
Let X be the normal variable with mean μ =50 and standard deviation σ =2
We have to find probability that x is between 47 and 54
P(47 < X < 54) = P(X < 54) - P(X < 47)
=
- 
= P(Z < 2) - P(Z < -1.5)
Using standard normal z score table to find probabilities we get
P(Z < 2) = 0.9772
P(Z < -1.5) = 0.0668
P(47 < X < 54) = P(Z < 2) - P(Z < -1.5)
= 0.9772 - 0.0668
P(47 < X < 54) = 0.9104
The probability that x is between 47 and 54 is 0.9104
Answer: (4, -2)
<u>Step-by-step explanation:</u>
Inverse is when you swap the x's and y's: (-2, 4) --> (4, -2)
