Answer:
The answer is 170
Step-by-step explanation:
Because 8 + 9 = 17, if we multiply all of these values by ten or add a zero to the end of each number, we should get
80 + 90 = 170
Answer:
143
Step-by-step explanation:
Your equation to find x is:
140+146/2 = 143
Composing function is applying one function to the result of another and an arithmetic operation is when you add, subtract, multiply, or divide two functions.
-45 + 150 = 105
Carol has $105 in her account after receiving her paycheck.
To approximate the P(x<27) we need to find the z-score of the data, this will be given by:
z=(x-μ)/σ
where:
μ-mean
σ-standard deviation
x=27, μ=32, σ=4
z=(27-32)/4
z=-5/4
z=-1.25
thus
P(x<27)=P(z<-1.25)
=0.1056
=10.56%
Answer: 10.56%
