The cost of 5 gallons of ice cream has a standard deviation of 7 dollars with a mean of 25 dollars during the summer. What is 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?
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

Answer:
Following are the code to this questiuon:
def fiv(y):#defining a method fiv that hold a parameter
x = str(y) #defining a variable x that convert the value y in string
return three(x[0:3]) and three(x[1:4]) and three(x[2:5])#use return keyword to call the method three
def three(x): #defining a method three that hold x variable as a parameter
y = int(x) #use y to convert x in integer
return y>=100 and (y%17==0 or y%23==0) #use return that gives a value which is divisiable by 17 or 23
print([y for y in range(10000,40000) if fiv(y)])#use print method to print value
Output:
Please find the attached file.
Step-by-step explanation:
In the above code, two methods "fiv and three" is declared that accepts one variable as a parameter, which can be defined as follows:
In the fiv method, an "x" variable is defined that covert the value into a string and use to call the three methods.Inside the three methods, a y variable is declared, that convert the value into integer and use return keyword, that checks value is divisible by 17 or 23. In the print method, it accepts the given value, which is passed in the loop to print the value.Which car will travel the greatest distance (in miles) per gallon?

(a) Find the p - value for the test statistic =1.34
z=1.34 for the following null and alternative hypotheses:
0:=50
HA:μ>50
The p - value is
Look at a z table and look up z = 1.34.
The number associated with z = 1.34 is 0.9099
The p value is that value subtracted from 1.
P value = 1 − 0.9099 = 0. 0901
The p - value for the test statistic should be considered as the 0.0901.
Calculation of the p-value:Since there is null and alternative hypotheses
so here we look at the z table and then the value should be 1.34
So, the value of z in 1.34 should be 0.9099
So, here the p-value should be
= 1 - 0.9099
= 0.0901
hence, The p - value for the test statistic should be considered as the 0.0901.

Find the value of x.
Answer:
The answer is 109 degrees.
Step-by-step explanation:
Any triangle's angles add up to 180 in total, so we can create the equation 64+45+__=180. Using some simple algebra we can change this equation into the equation 180-109=71. This solves the inner triangle, and the outside angle, x is supplementary (meaning it adds up to 180) to 71. 180-71 = 109.

if angle 3 and angle 4 are corresponding angles, then their vertical angles are also corresponding angles
always sometimes or never
Explanation:
Drawing out a diagram usually helps with these types of problem. See the diagram below.
We have angle 3 and angle 4 as corresponding angles (since they are both in the north east corner of each four-corner configuration). Angle 1 = angle 3 is one pair of vertical angles and angle 2 = angle 4 is another pair of vertical angles. We see that angles 1 and 2 are corresponding angles in the south west corners of each four-corner configuration. That's why the original statement is always true.

A rectangular garden must have a perimeter of 155 feet and an area of at least 1400 square feet. Describe the possible lengths of the garden. Round your answers to the nearest foot. The approximate length of the garden is at least feet and at most feet.
Answer:
Step-by-step explanation:
Perimeter of a garden = 2(L+W)
Area of the gerden = LW
L is the length
W is the width
Given
Perimeter = 155ft
Area = 1400ft²
Substitute
1400 = LW
155 = 2L+2W
from 1;
W = 1400/L
Substitute into 2;
155 = 2L + 2(1400/L)
155 = 2L + 2800/L
155L = 2L² + 2800
2L²-155L + 2800 = 0
Factorize
L = 155±√155²-4(2)(2800)/4
L = 155±√24025-22400/4
L = 155±√1625/4
L = L = 155±40.31/4
L = 194.31/4
L = 48.82 feet and;
L = 155-40.31/4
L = 28.67ft
Hence the approximate length of the garden is at least 28.67 feet and at most 48.82 feet.
The possible lengths of the garden are:
The least approximate length = 29 feet
The most approximate length = 49 feet
The area of the rectangle is at least 1400 square feet
That is:
Area ≤ 1400
Let the length be represented by L
Let the width be represented by W
Let the area be represented by A
The area of a rectangle is:
Area = Length x Width
A = LW
LW ≥ 1400....................(1)
The perimeter of the rectangle is 155 feet
P = 2(L + W)
2(L + W) = 155............(2)
Make W the subject of the formula
L + W = 155/2
L + W = 77.5
W = 77.5 - L.............(3)
Substitute W = 77.5 - L into equation (1)
L(77.5 - L) ≥ 1400
77.5L - L² ≥ 1400
-L² ≥ 1400 - 77.5L
0 ≥ L² - 77.5L + 1400
L² - 77.5L + 1400 ≤ 0
Solving the quadratic inequality above
29 ≤ L ≤ 49
The least approximate length of the garden = 29 feet
The most approximate length of the garden = 49 feet

We want to compare the quality of three Tablet products: Tablet Product A has a Mean Time Between Failures (MTBF) 10,000 hours, and a Mean Time To Repair (MTTR) or 10 hours. Product B has a MTBF of 11,000 hours and a MTTR of 11 hours. Product C has a MTBF of 12,000 hours and MTTR of 12 hours. Which tablet has better Availability
Answer:
The Availability of tablets A,B and C are equal
Step-by-step explanation:
Computation for Which tablet has better Availability
Using this formula
Availability of Tablet=MTBF/ ( MTBF + MTTR)
Where,
MTBF represent Mean Time Between Failures
MTTR represent Mean Time To Repair
Let plug in the formula
Availability of Tablet A = 10,000hrs/(10,000hrs + 10hrs)
Availability of Tablet A= 0.999
Availability of tablet B = 11,000hrs/( 11,000hrs + 11hrs )
Availability of Tablet B= 0.999
Availability of Tablet C = 12,000hrs/ ( 12,000hrs + 12hrs)
Availability of Tablet C= 0.999
Based on the above calculation the Availability of all the 3 tablets are equal
Therefore the Availability of tablets A,B and C are equal.
