If f(x) = -x +6 and the domain of f is { 3, 7 , 11}, what is the range of f(x)?
Answer:
The domain of a function f(x) is the set of all values for which the function is defined, and the range of the function is the set of all values that f takes. (In grammar school, you probably called the domain the replacement set and the range the solution set.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the total number of girls in the class be = G
Now , let the total number of boys in the class be = B
The total number of students in the class = S
The value of S = 30 students
The percentage of boys in the class = 40 %
So , the equation will be
The number of boys in the class = percentage of boys in the class x total number of students in the class
Substituting the values in the equation , we get
The number of boys in the class = ( 40/100 ) x 30
The number of boys in the class = 30 x 0.4
The number of boys in the class = 12 boys
So , the number of girls in the class = total number of students in the class - number of boys in the class
Substituting the values in the equation , we get
The number of girls in the class = 30 - 12
The number of girls in the class = 18 girls
Therefore , the value of G is 18 girls
Hence , The number of girls in the class is 60% or 18 girls

Answer:
Shirts : $24
Pants : $23.80
Shoes : $21
Ties : $30.60
Step-by-step explanation:
For the shirt : Price = $15 Discount = 20% 2 shirts are bought
Price after the discount = (100% - 20%) x (2 x $15) = $24
For the pair of pants : Price = $28 ; Discount = 15% ; 1 pair of pants is bought
Price after the discount = (100% - 15%) x $28 = $23.80
For the shoes : Price = $35 Discount = 40% 1 pair of shoes are bought
Price after the discount = (100% - 40%) x $35 = $21
For the tie: Price = $12 Discount = 15% 3 ties are bought
Price after the discount = (100% - 15%) x ( 3 x $12) = $30.60
Answer:
Shirts : $24
Pants : $23.80
Shoes : $21
Ties : $30.60
Step-by-step explanation:
For the shirt : Price = $15 Discount = 20% 2 shirts are bought
Price after the discount = (100% - 20%) x (2 x $15) = $24
For the pair of pants : Price = $28 ; Discount = 15% ; 1 pair of pants is bought
Price after the discount = (100% - 15%) x $28 = $23.80
For the shoes : Price = $35 Discount = 40% 1 pair of shoes are bought
Price after the discount = (100% - 40%) x $35 = $21
For the tie: Price = $12 Discount = 15% 3 ties are bought
Price after the discount = (100% - 15%) x ( 3 x $12) = $30.60

Answer:
a = 14.73
Step-by-step explanation:
This ratio can also be written like this:
[tex]\frac{a}{27} = \frac{6}{11}[/tex]
Then you can cross multiply to get
11a = 6 x 27
11a = 162
Divide both sides by 11
11a / 11 = 162 / 11
a = 14.73

Oil is spilled onto a kitchen floor. The area covered by the oil at time t is given by the function A, where A(t) is measured in square centimeters and t
is measured in seconds. Which of the following gives the rate at which the area covered by the oil is changing at time t=10?
Answer:
did you ever fine out the answer to this lol
Step-by-step explanation:
Oil is spilled onto a kitchen floor. The area covered by the oil at time t is given by the function A, where A(t) is measured in square centimeters and t
is measured in seconds. The rate at which the area covered by the oil is changing at time t = 10 is A'(10).
Given that:
The area covered by the oil at time t = A(t)To determine the rate at which the area covered by the oil is changing with time, we need to differentiate A(t) with respect to time t.
∴
By differentiation:
[tex]\mathbf{\dfrac{dA}{dt} =A'(t)}[/tex]
The rate at which the area covered with oil is changing is t = 10∴
[tex]\mathbf{\dfrac{dA}{dt} \Big| _{t=10}=A'(t)\Big|_{t=10}}[/tex]
[tex]\mathbf{\dfrac{dA}{dt} =A'(10)}[/tex]
Therefore, we can conclude that the rate at which the area covered by the oil is changing at time t=10 is A'(10).

You have $5.50 in your pocket and then you receive $5.50 for doing your chores.You have $5.50 in your pocket and then you receive $5.50 for doing your chores.
Answer:
For the first three situations, the sum is zero.
Step-by-step explanation:
As the expenses are negative of earnings, so assuming the earning amount is positive while the spending amount is negative.
Shawna spends $20 and she earns $20,
So, the sum of the total amount is
-20+20=0
A diver dove down 20.14 feet under-water and then descended 20.14 feet.
First, the diver ascends 20.14 feet then descends the same.
As the ascending and the descending are opposite to each other.
The sum of both is
+20.14-20.14=0
So, in this case, the diver has a sum of zero.
For shooting over par the golfer have +2 points while for shooting under par the golfer have -2 points,
So, the total points are
+2-2=0
So, in this case, the golfer has a sum of zero points.
In the last case, you already have $5.50 in your pocket and then you receive $5.50 for doing your chore.
This time, there is an addition of $5.50 to the money you already have.
So, the total money, after receiving the $5.50 is
$5.50+$5.50=$11
In this case, the sum of the total amount is not zero.
Hence, for the first three situations, the sum is zero.

What distribution of clothing should Nancy have for German males and females? Should she produce more small or large sizes, or should she have an even distribution of all sizes?
Answer: I sacrificed my answer for yours here u go love
Step-by-step explanation:
Nancy should produce more large sizes of the male clothing for German men since the data is skewed left, meaning there are more data values that lie on the right side, representing taller males. For women, she can have a roughly even distribution of sizes since the data set is symmetric.
Nancy should produce more large sizes of the male clothing for German men and for women, she can have a roughly even distribution of sizes since the data set is symmetric.
What is skewness in histogram?Skewness is the tendency for the values to be more frequent around the high or low ends of the x-axis.Skewness is the measure of the asymmetry of a histogram (frequency distribution). A histogram with normal distribution is symmetrical.Given is to find what distribution of clothing should Nancy have for German males and females.
The shape of the data for German male adult heights is skewed left, but the shape of the data for female adult heights is close to symmetric. So, the distribution of the data is not the same. Each data set has the same minimum height of 145 centimeters. However, the maximum male adult height is 220 centimeters and the maximum female height is 185 centimeters. So, the range of values is not the same. The data for male adult heights has an outlier, but the data for female adult heights doesn't have any outliers.Nancy should produce more large sizes of the male clothing for German men since the data is skewed left, meaning there are more data values that lie on the right side, representing taller males. For women, she can have a roughly even distribution of sizes since the data set is symmetric.
Therefore, Nancy should produce more large sizes of the male clothing for German men and for women, she can have a roughly even distribution of sizes since the data set is symmetric.
