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
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.

Solve the equation F= 9/5C + 32 for c
Put the steps in correct order
5(F-32) = 9C
F-32 = 9/5C
5/9(F-32)=C
Answer:
1. [tex] F - 32 = \frac{9}{5}C [/tex]
2. [tex] 5(F - 32) = 9C [/tex]
3. [tex] \frac{5}{9}(F - 32) = C [/tex]
Step-by-step explanation:
Given:
[tex] F = \frac{9}{5}C + 32 [/tex]
Required:
Solve for C
Solution:
In order to solve C, we need to isolate C in[ tex] F = \frac{9}{5}C + 32 [/tex] by following the steps below:
Step 1: subtract 32 from each side
[tex] F - 32 = \frac{9}{5}C [/tex]
Step 2: Multiply both sides of the equation by 5
[tex] 5(F - 32) = 9C [/tex]
Step 3: Divide both sides by 9
[tex] \frac{5}{9}(F - 32) = C [/tex]
1. Solve the equation. (1 point)

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.

TRUE OR FALSE: When working with y=mx+b, m stands for the slope and b 1 poir
stands for the y-intercept.
O True
False
Answer:
True
Step-by-step explanation:
y= mx + b
y= slopex + y intercept
slope would be the rise and run with x, then you'd add the y intercept
ex: y= 3x + 7

Step-by-step explanation:
The Farmers Market sells apples by the bushel, and each bushel of apples weighs 42 lbs. A bushel of large apples contains 84 apples. If a bushel of small apples contains twice as many apples as a bushel of large apples, how many small apples are in 1 lb of apples?
Megan purchased a bushel of apples from the Farmers Market that contained only large and small apples. There were exactly 129 apples in the bushel Megan purchased. Based on this and information from the previous problem, what is the positive difference between the number of large apples and the number of small apples in the bushel of apples Megan purchased?

5 1/5 - 5/12 ÷ (1/6 × 2/3)=
Answer:
47.8
Step-by-step explanation:
What you want to do first is 5 1/5 - 5/12 which is 4.78,
then 1/6 x 2/3, which is 0.1,
then you do 4.78 divided by 0.1, which is 47.8
Find the number of five-digit numbers less than 40 000 in which the three-digit numbers formed by a consecutive digits are all divisible by either 17 or 23. Remember, zero cannot be the first digit in a three-digit number.
Please show grade 7 math work
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.What is an equation of the line with slope 5 and y-intercept 8?
Answer:
y=5x+8
Step-by-step explanation:
You need have the slope-intercept formula:
y=mx+b
m=slope
b=y-intercept
You replace the m and b with the slope and y-intercept which is 8
y=5x+8

How would you write a phrase that represents the expression 7(n - 12)?
The perimeter of a triangle is 24 cm. The shortest side is one-fourth of the longest side. The other side of the triangle is three-fourths of the longest side. What is the length of the shortest side?
Answer:
12cm
Step-by-step explanation:
Shortest side = [tex]\frac{1}{4}x[/tex]
Other side = [tex]\frac{3}{4}x[/tex]
Longest side = [tex]x[/tex]
[tex]24 = x + \frac{1}{4}x + \frac{3}{4}x\\24 = 2x\\12 = x[/tex]
Therefore, longest side is equal to 12cm.
