feet as a single fraction greater than one. Then, complete the expression PLEASE HELP ASAP
The complete expression of given question is :
3 5/6 feet = 23/6 feet = 46 inches.
What do you mean by term Mixed Fraction ?A mixed fraction is a type of fraction that consists of a whole number and a proper fraction. For example, 3 1/2, 2 2/3, and 5 3/8 are all mixed fractions. The whole number part represents a number of whole units, while the fraction part represents a part of a unit.
To write 3 5/6 feet as a single fraction greater than one, we can convert the mixed number to an improper fraction. To do this, we multiply the whole number (3) by the denominator of the fraction (6), and add the numerator (5), then put the result over the denominator. Like this:
3 5/6 = (3 x 6 + 5)/6 = 23/6
Therefore, 3 5/6 feet can be written as the improper fraction 23/6 feet.
To complete the expression, we can use the fact that 1 foot is equal to 12 inches. Therefore, we can convert 23/6 feet to inches by multiplying it by 12:
23/6 feet × 12 inches/1 foot = 23/6 × 12 inches
Simplifying the fraction, we get:
23/6 × 12 inches = 276/6 inches = 46 inches
Therefore, the expression is:
3 5/6 feet = 23/6 feet = 46 inches.

Solve the systems by elimination.
10x + 10y = 40
5x + 3y = 8
Answer:
x = -2, y = 6
Step-by-step explanation:
First, find the opposite of 10 by multiplying 5x+3y=8 by -2 to eliminate 10x.
10x+10y=40
-2(5x+3y=8)
10x+10y=40
-10x-6y=-16 (Subtract 10y - 6y) (Subtract 40 - 16)
4y = 24 (Divide by 4 on both sides)
y = 6
Substitute 6 in the y value in any of the equations.
10x+10(6)=40 (Replaced 10y with 10(6) )
10x+60=40
-60 = -60 (Subtract 60 from both sides)
10x = -20 (Divide by 10 on both sides)

In a class of 20 children, 8 had one sister, 6 had 2 sisters. The mean number of children was 1. how many children had no sisters
There are no children in the class who have no sisters. This is because the mean number of children is 1, and some children have more than one sibling to Balance out those who have only one.
To solve this problem, we need to use some basic principles of statistics and probability. Let's start by identifying the key information provided in the problem. We know that there are 20 children in the class, and that some of them have sisters. Specifically, 8 children have one sister and 6 children have two sisters. We also know that the mean (average) number of children is 1, which means that on average, each child has one sibling.
To find out how many children had no sisters, we can use the following formula:
Total number of children - (number of children with one sister x 1) - (number of children with two sisters x 2) = number of children with no sisters
Using the values from the problem, we get:
20 - (8 x 1) - (6 x 2) = 0
This means that there are no children in the class who have no sisters. While this may seem counterintuitive, it's important to remember that the mean number of children is 1, which means that some children must have more than one sibling in order to balance out the others who have only one.
In summary, the answer to the question is that there are no children in the class who have no sisters. This is because the mean number of children is 1, and some children have more than one sibling to balance out those who have only one.

Tom and John are engaged in buying and selling certain products A and B. Tom BUYS 5 of product A but
SELLS twice as much of product B. John on the other hand SELLS three times what Tom BOUGHT of
product A and BUYS 13 of product B. At the end of the business day, John banks Ksh 110,000/- while
Tom banks Ksh 230,000.
Under the assumption that the sale prices for product A and B are the same for the two men, and the costs prices for the products A and B are also the same for the two men, obtain the following:
The price for product A which was determined as Ksh 42,727.27 and the price for product B as 44,363.63
Question: If there was a mark up of 25% on the cost price and a discount of 15% on the sale price, how
much would each of the partners have banked at the end of the business day?
Product A is priced at Ksh 55,000, while Product B is priced at Ksh 32,000.
How to calculate Product A and B?Assume that the selling price for both the two items A and B is "S" and the cost price for both is "C". Using this knowledge, we can create two equations that relate the costs and revenues of the two items, one for Tom and one for John:
Tom: 5C - 2(5S) = [tex]P_1[/tex]
John: 3(5C) - 13C = [tex]P_2[/tex]
where [tex]P_1[/tex] and [tex]P_2[/tex] represent Tom's and John's respective profits.
We are aware that John deposits Ksh. 110,000 while Tom deposits Ksh. 230,000 at the end of the business day. Thus, we can say:
[tex]P_1[/tex] = 230,000 - 5C
[tex]P_2[/tex] = 110,000 - 18C
These values are what we obtain when we enter them into the equations for Tom and John:
5C - 2(5S) = 230.000 - 5C
When we simplify these equations, we obtain:
10C - 10S = 230,000
2C = 110,000
Solving for C, we get:
C = 55,000
We may determine S by adding this value back into the original equation:
10(55,000) - 10S = 230,000
Simplifying this equation, we get:
S = 32,000
Therefore, the price for product A is Ksh 55,000 and the price for product B is Ksh 32,000.

Answer:
$1.53
Step-by-step explanation:
You want to know the total tax on purchases of $4.56, 12.45, and 2.13 if the tax rate is the sum of 6.5% and 1.5%.
TaxThe tax is the product of the tax rate and the total of purchases. The tax rate will be the sum of the state and county tax rates:
6.5% +1.5% = 8% = 8/100
The attached calculation shows the tax is $1.53 after rounding to cents.
The tax rate on Mary Lou Mason's purchases is $1.53.
What is meant by rate?
In mathematics, rate usually refers to the ratio of two quantities that have different units of measurement.
To calculate the total tax on Mary Lou Mason's purchases, we need to first calculate the total cost of her purchases, including both the prices of the items and the sales tax.
The total cost of Mary Lou Mason's purchases before taxes is:
$4.56 + $12.45 + $2.13 = $19.14
To calculate the sales tax, we need to multiply the total cost of the purchases by the sum of the state and county tax rates:
6.5% + 1.5% = 8%
So the sales tax rate is 8%.
To calculate the total tax on Mary Lou Mason's purchases, we multiply the total cost of the purchases by the sales tax rate:
$19.14 x 8% = $1.53
Therefore, the tax on Mary Lou Mason's purchases is $1.53.

Hamilton had a 21-man company in its first (currently only ongoing) production. There are 720 ways that can play as cast.
Hamilton had a 21-man company in its first (currently only ongoing) production, so we really know a little about our army of volunteers (all of which I think are good enough to hold the show to a high standard), but that's not necessarily the case. The problem - Thomas Kail and Andy Blanken buehler use their team of 11 in their Broadway productions to great effect, but a team of the same size. It's an art choice.
When it comes to the main body, there are actually 14 named locations, with a lot of work through singing and/or dialogue, in addition to the many things the members use from Kail products. This prevents all volunteers from being an essential part because that leaves us only 3 people in total which seems a bit lackluster in some big productions.
One solution is to have some minor roles played by the band members - for example James Madison, King George III, Peggy Schuyler and Maria Reynolds - so now we have 9 key characters and 8 groups that we need to succeed. compact performance.
My preference is to follow a Broadway production, so we have 10 main actors, so the ensemble is 7 people. If necessary, with the help of a small part of the main cast, we can expand the group in many performances.
Therefore, there are 10!/7! = 720 ways .

Task 1: What is and what is ?
Task 2: What are the mean and standard deviation?
Task 3: What are the conditions that must be met to use the normal approximation to the binomial
distribution? Are they met?
Thus, the mean and standard deviation for the randomly selected individuals is found as: mean = 80.1 and standard derivation = 7.66.
Explain about the standard deviation:The standard deviation is a measurement of how widely spaced out a set of data is from the mean. The bigger the dispersion or variability, the higher the standard deviation and the greater the magnitude of the value's divergence from its mean. It represents the absolute variability of a distribution.
Given data:
Number of population n = 300
probability p = 0.267
Mean is given as np:
np = 300*0.267
np = 80.1
standard derivation: √np(1 - p)
√np(1 - p) = √80.1(1 - 0.267)
√np(1 - p) = √58.7133
√np(1 - p) = 7.66
