The lengths of a professor's classes has a continuous uniform distribution between 49.29 min and 55.55 min. If one such class is randomly selected, find P54
Answer:
52.6704
Step-by-step explanation:
The lengths of a professor's classes has a continuous uniform distribution between 49.29 min and 55.55 min
Let x = 49.29, y=55.55
Percentile(P) = 54/100 = 0.54
P54 = x+(y-x)p
P54 = 49.29 + (55.55-49.29)*0.54
P54 = 49.29 + 6.26*0.54
P54 = 49.29 + 3.3804
P54 = 52.6704

Faliha runs around a square field of side 70m, while Rameen runs around a rectangular field with length 90m and breadth 60m. Who covers more distance by how much?
[tex]\huge\sf\green{Answer :- }[/tex]
Given :- Side of the square field = 70mLength of the rectangular field = 90mBreadth of the rectangular field = 60mTo Find :-Perimeter of the square fieldPerimeter of the rectangular fieldSolution :-Perimeter of the square = 4 × side
By substituting values,
⇒ 4 × 70m
➥ 280m
Hence, Faliha runs 280m around a Square fieldPerimeter of the rectangle = 2( length + Breadth)
By substituting values,
⇒ 2( 90m + 60m )
⇒ 2( 150m)
➥ 300m
Hence, Rameen runs 300m around a rectangular fieldBy comparing perimeters, Rameen runs more than Faliha
Distance runs more by rameen = Distance covered by rameen - distance covered by faliha
By substituting values,
⇒ 300m - 280m
➠ 20m
Hence, Rameen runs more around a rectangular field by 20m[tex]\huge\sf\fcolorbox{red}{pink}{ItzDevilGirl}[/tex]

how to do 15 1/2 - 2 1/10 how to do it
First, you need to make the fractions have the same denominator:
15 1/2 ---> 15 + (1/2 x 5) = 15 5/10
2 1/10 ---> 2 1/10
Then you need to subtract them from each other:
15 5/10
- 2 1/10 (or) 15 5/10 - 2 1/10 = 13 4/10
13 4/10
This gets the answer: 13 4/10

To determine the average price of hotel rooms in Atlanta, a sample of 49 hotels was selected and the sample mean price of hotel rooms, top enclose y is $120. The population standard deviation was found to be $16. What is the standard error of top enclose y
Answer:
Standard error of top enclose y = 2.29
Step-by-step explanation:
The formula for Standard error = σ/√n
σ is the population standard deviation = $16
n is random number of samples = 49 hotels
Hence,
Standard error = 16/√49
= 16/7
= 2.2857142857
Approximately = 2.29
Therefore, the Standard error of top enclose y = 2.29

g How many hours would it take to read a book that you tend to read at a rate of 1.26 pages per minute, if it is 911 pages long
Answer: It will take about 19 hours to read the book.
Step-by-step explanation:
Given: Rate of reading = 1.26 pages per minute
Total pages = 911 pages
Time taken to read = (Rate of reading ) x (Total pages to read)
= 1.26 x 911 minutes
= 1147.86 minutes
[tex]=\dfrac{1147.86}{60}[/tex] hours [ 1 hour = 60 minutes]
= 19.131 hours
hence, it will take about 19 hours to read the book.

Oliver shot 8 free throws at practice, making 6 free throws and missing 2 free throws. If Oliver is equally likely to make a free throw as he is to miss a free throw, find the probability of this outcome by expanding (m+n)8.
Answer: Then you turn the 6 to a 4 and the 2 into a 4 also. Because Oliver wanted the free throw and the free throw he missed turn both equal so you divide 8 with 2 and get 4.

A baker has 12 pounds of almonds. She puts them in a bag so that each bag has the same weight. Clare and Tyler drew diagrams and wrote equations to show how they were thinking about 12 ÷ 6. How do you think Clare and Tyler thought about 12 divided 6? Explain what each diagram and each part of each equation (especially the missing number) of might mean in the context of the bags of almonds.
Answer:
12 is how many pound of almonds there are. 6 is how many bags. 2 is how many almons there are in one bag for Tyler. For Clare is 12 almonds when there are 2 bags and there are 6 almonds in each bag.
Step-by-step explanation:
For Clare there is 12 almonds, there are 2 bags and there are 6 almonds in each bag.
How can we interpret the division?When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division, thus, can be interpreted as equally dividing the number that is being divided in total x parts, where x is the number of parts the given number is divided.
We are given that baker has 12 pounds of almonds.
Since Clare and Tyler drew diagrams and wrote equations to show how they were thinking about 12 ÷ 6.
12 is the pound of almonds there and 6 is the bags.
We conclude that 2 is how many almonds there are in one bag for Tyler.
For Clare is 12 almonds, when there are 2 bags and there are 6 almonds in each bag.

Expression equivalent to 8p-3n+4q-9m
Answer:
4p-n+2q-3m is equivalent to 8p-3n+4q-9m
The expression 4(2p+ q) - 3(n+3m) is equivalent to the given expression. which is the correct answer would be an option (C).
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
The expression is given in the question following:
8p - 3n + 4q - 9m
We have to determine the equivalent expression to the given expression
As per option (C), we have
⇒ 4(2p+ q) - 3(n+3m)
Apply the distributive property of multiplication,
⇒ 4 × 2p+ 4 × q - 3 × n + 3 × m
⇒ 8p + 4q - 3n + 3m
Rearrange the terms in the above expression,
⇒ 8p - 3n + 4q - 9m
So this expression is the same as the given expression.
Therefore, the expression 4(2p+ q) - 3(n+3m) is equivalent to the given expression.

Outside a home, there is a 10-key keypad with the letters A, B, C, D, E, F, G, H, I, and J that can be used to open the garage if the correct ten-letter code is entered. Each key may only be used once. How many codes are possible? The number of possible codes is:_____
Answer:
3,628,800 (aka "10!")
Step-by-step explanation:
The first letter in the code can be 10 possible letters.
Since every letter can only be used once, the second letter can only be 9 possible letters.
E.G.: If the first letter is A, the second letter is B-J.
The third letter would be 8 possible letters, than the fourth would be 7, etc.
In math form, figuring out the possible combinations would be written out as so:
10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1
An easier way to write this out would be using "10!", which stands for "10 Factorial"
The result of the above equals 3,628,800.
