Answer:
0.000221
Step-by-step explanation:
Using the z score formula when a random number of samples is given =
z = (x-μ)/σ/√n, where
x is the raw score
μ is the population mean
σ is the population standard deviation = 7
n is random number of samples = 83
Note that:2.2 dollars = x-μ
z = 2.2/7/√8.3
z = 3.51402
Probability value from Z-Table:
P(x<27.7) = 0.99978
P(x>27.7) = 1 - P(x<27.7) = 0.00022069
Approximately = 0.000221
Hence, the probability that the sample mean would differ from the true mean by greater than 2.2 dollars if a sample of 83 5-gallon pails is randomly selected is 0.000221
Given:
The function is
Consider the given domain of g is {-2,0,2}.
To find:
The solution set if the domain of g for the given domain.
Solution:
Domain is the set of input values and range is the set of output value.
We have,
Domain of g is {-2,0,2}.
For x=-2,
For x=0,
For x=2,
Now, the solution set of the given domain of g is
Therefore, the solution set is {18,12,6}.
X = 2
y = 3
You can simply set these two equal to each other and solve for x. Then plug in to find y.
Answer:
x = 31
Step-by-step explanation:
The sides of an isosceles trapezoid are the same length, so ...
5x -32 = 2x +61
3x = 93 . . . . . . . . add 32-2x
x = 31 . . . . . . . . . . divide by 3
