Step-by-step explanation:
In a sale, the football club shop reduced the price of the football shirts to $23.80.
An error was made when working out this sale price.
The price was reduced by 30% instead of 20%.
Calculate the correct sale price for the football shirt.
The correct sales price for the football shirt is $24.75.
What is the correct sales price?The first step is to determine the initial price of the shirt before the 30% discount was applied:
(1 + 0.3) x 23.80 = $30.94
The second step is to now apply the appropriate discount rate:
(1 - 0.2) x 30.94 = $24.75

If a researcher is using a t statistic to test a null hypothesis about a population, what information is needed from the population to calculate the t statistic?.
The T statistic does not require any information about the population.
The T - statistic is the ratio of the predictable value of a parameter from its hypothesized value to its standard disputable values.
The T statistic uses the sample variance instead of the population variance.
Since, the T statistic depends on the hypothesized population mean. So in place of the standard deviation of population, size or mean of the population, T-statistic depends on the sample mean, the sample standard deviation and the sample size .
Thus, The T-statistic does not require any information about the population

If f(x) = 3x-2 and g(x) = x +1, find (f+g)(x).
Answer:
[tex]\huge\boxed{\sf (f+g)(x) = 4x - 1}[/tex]
Step-by-step explanation:
Given functions:f(x) = 3x - 2g(x) = x + 1Solution:Add both functions
(f+g)(x) = 3x - 2 + x + 1
Combine like terms
(f+g)(x) = 3x + x - 2 + 1
(f+g)(x) = 4x - 1
[tex]\rule[225]{225}{2}[/tex]
Answer:
[tex](f+g)(x)=4x-1[/tex]
Step-by-step explanation:
FunctionsFunctions written in equation form usually have several parts:
nameinputMathematical rule/expression that tells what the function does to the input to give an output.So, for instance, [tex]g(x)=x+1[/tex] has a name of "g", has an input of "x", and has a rule that it adds 1 to the input to get the output.
The name of the function should tell what rule to follow (look for the equation with that function name), or it may give some details on what the function does.
Dealing with so many different problems, functions often get a default name of "f", "g", or "h".
If a function is special and/or used commonly, it will sometimes get a special name (like the natural logarithm function "ln").
This functionIn this case, the function is (f+g)(x). The function name means that the result of each function, f and g, will be added together, while using the same input "x" for both functions.
[tex](f+g)(x)=f(x)+g(x)\\=(3x-2)+(x+1)\\=3x+(-2)+x+1\\=4x+(-1)\\=4x-1[/tex]
So, given these two functions for "f" and "g", [tex](f+g)(x)=4x-1[/tex]

To gauge how strongly two variables are related to one another, correlation coefficients are used.
A statistical indicator of the strength of the association between the relative movements of two variables is the correlation coefficient. The values are in the -1.0 to 1.0 range. There was a measurement error in the correlation if the estimated value was larger than 1.0 or lower than -1.0. Perfect negative correlation is shown by a correlation of -1.0, and perfect positive correlation is shown by a correlation of 1.0. A correlation of 0.0 indicates that there is no linear link between the two variables' movements. Finance and investing can benefit from the usage of correlation statistics.

A) 6+1.5π
B) 6+2π
C) 12+ 1.5π
D) 12+2π
The perimeter of each region is 12 + 1.5π if a circle with an area of 36π is divided into 8 congruent regions
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
Let r represent the area of the circle, hence:
Area = πr²
36π = πr²
r = 6 units
Perimeter = 2πr = 2π(6) = 12π
The circle has 8 congruent regions, hence:
Perimeter of each region = 6 + 6 + 12π/8 = 12 + 1.5π
The perimeter of each region is 12 + 1.5π if a circle with an area of 36π is divided into 8 congruent regions

One side of a triangle has length $10$, and the triangle has integer perimeter. What is the smallest possible perimeter of the triangle
The smallest possible perimeter of the triangle is 21.
The third important property of triangles is the triangle inequality rule, which states: that the length of a side of a triangle is less than the sum of the lengths of the other two sides and greater than the difference between the lengths of the other two sides.
so let 10 = a
10 < b+c
So a good integer value for b+c would be 11
10 > b-c
If we let b be the bigger of the two 10 and 1 would work for b and c respectively or 7 and 4 or 6 and 5 or 6.5 4.5, etc

(x-5y,-3):(1,3y-x) find value of x and y
Please help me to solve thiss!!
Answer:
x=11, y=2
Step-by-step explanation:
We can set 1 equal to x-5y and then solve for x. and y.
x = 5y+1
y = x-1/5
We can use this information and plug back in the values for 3y-x or x-5y.
We can set -3 = 3y-x or 1 = x-5y.
To solve for x using -3 = 3y-x we can swap the values of x and y which would make it -3 = 3(x-1/5)-5(x-1/5)+1.
We can do a bit of algebra which would get us x = 11.
Knowing that y = x-1/5 we can plug in 11 for x. y = 11-1/5.
y=2
x=11, y=2

How many solutions exist for the given equation?
3(x – 2) = 22 – x
zero
one
two
infinitely many
Answer:
C. Infinitely many
Step-by-step explanation:
First, find x.
3(x-2)=22-x
Use distributive property.
3x-6=22-x
Add x to both sides.
4x-6=22
Add 6 to both sides.
4x=28
Divide 4 from both sides.
x=7
Plug in 7 for x into the original equation.
3(7-2)=22-7
3(5)=22-7
15=15
Since 15 does equal 15, the answer has infinitely many solutions.

A bike store marks up the wholesale cost of all bikes they sell by 30%. calvin wants to buy a bike that has a price log of 123.50. what was the wholesale cost of the bike?
The wholesale cost of the bike is 95.
Wholesale price is the price charged for a product as sold in bulk to large trade or distributor groups as opposed to what is charged to consumers.
The selling price is how much a buyer pays for a product or service.
The profit formula is used to calculate the amount of gain that has been made in a transaction
Profit = Selling Price (S.P.) - Cost Price (C.P.)(here it is the wholesale price)
Given =
Selling Price = 123.50Wholesale price = ?Profit = 30% of wholesale priceSubstituting it in the profit formula we get
0.3 x wholesale price = 123.50 + wholesale price
1.3 x wholesale price = 123.50
Wholesale price = [tex]\frac{123.50}{1.3}[/tex] = 95

Answer:
The given relation {(5,2),(6,1),(6,2),(4,8)} is not a function.
Step-by-step explanation:
The relation {(5,2),(6,1),(6,2),(4,8)} is given.
It is required to determine whether the given relation is a function.
To determine whether the given function is a relation, identify the domain and range and then check whether the given relation is a function.
Step 1 of 1
The given relation is {(5,2),(6,1),(6,2),(4,8)}.
The set of the first components of each ordered pair is called the domain.
From the relation, the domain is {5,6,6,4}.
The set of the second components of each ordered pair is called the range.
From the relation, the range is {2,1,2,8}.
The domain of the function does not have a unique range. So, the given relation is not a function.
