Answer:
The separated values of x and y from the given equation is
Step-by-step explanation:
Given equation is
Now to find the separated values of x and y with the given equation.
Now find the value of x and so we have to separate the value x from the given equation
Therfore
Now find the value of y and so we have to separate the value y from the given equation
Therefore
The separated values of x and y from the given equation is
Step-by-step explanation:
p=2L+2w
factorise
p=2(L+w)
p=2(20+14)
p=2(34)
p=68
This is also a perimeter of a rectangle
Answer:
a) 0.194
b) $440.8
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = $9.40
Standard Deviation, σ = $4.40
Formula:
Standard error due to sampling =
a) P(tips from 40 parties > $400)
Thus, the average pay is
P(x > 10)
Calculation the value from standard normal z table, we have,
b) We have to find the value of x such that the probability is 0.01
Calculation the value from standard normal z table, we have,
Thus, the mean tip is $11.02
Tip for 40 parties =
Thus, he earns $440.8 on the best 1% of such weekends.
