= $ 36 for 1 week
$ 288 for x weeks
x = 288 divide 36
x = 8 weeks

For a data set, the mean is 3.17 and the range is 1.4. The data set is transformed by adding 0.5 to each data value. What are the mean and range of the new data set?
a. mean: 3.67; range: 1.9
b. mean: 3.67; range: 1.4
c. mean: 3.17; range: 1.9
d. mean: 3.17; range: 1.4
Adding 0.5 to each value in the data set increases the mean to 3.67 while the range remains at 1.4. Hence, the correct answer is option b.
When a constant is added to each data value in a data set, the mean of the data set increases by that constant, while the range remains unchanged. In this case, adding 0.5 to each data value will increase the mean by 0.5 but the range will stay the same.
Given the original mean: 3.17 and original range: 1.4:
New mean = 3.17 + 0.5 = 3.67
New range = 1.4
Therefore, the correct answer is option b: mean: 3.67; range: 1.4.

q-r=r solve for r
Please can someone explain this to me
To solve the equation q-r=r for r, add r to both sides to isolate the variable r. Then, divide both sides by the coefficient of r to find the value of r.
Explanation:To solve the equation q-r=r for r, we want to isolate the variable r on one side of the equation. To do this, we can add r to both sides of the equation:
q - r + r = r + r
This simplifies to:
q = 2r
Next, we can divide both sides of the equation by 2 to solve for r:
q/2 = r
Therefore, the solution is r = q/2.

Uta invests $345 into a simple interest investment account that pays interest at a rate of 9% a year. After several years, she withdraws her balance of $531.30. Using the formula l=Prt, how many years was her money invested? 4 years 5 years 6 years 7 years
Answer:
[tex]6\ years[/tex]
Step-by-step explanation:
we know that
The simple interest formula is equal to
[tex]I=P(rt)[/tex]
where
I is the interest amount
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have
[tex]t=?\ years\\ I=\$531.30-\$345=\$186.3\\ P=\$345\\r=0.09[/tex]
substitute in the formula above
[tex]\$186.3=\$345(0.09t)[/tex]
[tex]t=186.3/(345*0.09)=6\ years[/tex]
Triangle XYZ is shown on the coordinate plane below:
Triangle XYZ on the coordinate plane with ordered pairs at X 3, negative 1, at Y 4, negative 4, at Z 1, negative 2
If triangle XYZ is reflected across the line y = 1 to create triangle X'Y'Z', what is the ordered pair of X'?
The ordered pair of [tex]X'[/tex] is [tex](3,3)[/tex]
Explanation
According to the below diagram, the co ordinates of [tex]\triangle XYZ[/tex] are: [tex]X(3, -1), Y(4,-4)[/tex] and [tex]Z(1,-2)[/tex]
The triangle [tex]XYZ[/tex] is reflected across the line [tex]y=1[/tex] to create triangle [tex]X'Y'Z'[/tex]
Distance of the point [tex]X[/tex] from the line [tex]y=1[/tex] is 2 units.
So, the point [tex]X'[/tex] will be also 2 units above the line [tex]y=1[/tex]. As the triangle is reflected across a horizontal line, so the [tex]x[/tex] co-ordinate of the point will remain same.
[tex]y[/tex] co-ordinate of the point [tex]X'[/tex] will be: [tex]y=1+2 =3[/tex]
So, the ordered pair of [tex]X'[/tex] is [tex](3,3)[/tex]
Solve v=1/3bh for b, the base of the cone
Answer:
The base of cone is [tex]b= \frac{3V}{h} [/tex]
Step-by-step explanation:
Given :-
[tex]V =\frac{1}{3} \times b \times h[/tex] .............(1)
we need to solve for the base of cone
Divide both the side by ' h ' in equation (1)
[tex]\frac{V}{h} =\frac{1}{3} \times b[/tex]
Multiply both the sides by 3, in above expression
[tex]3\times \frac{V}{h} = b[/tex]
[tex]b= \frac{3V}{h} [/tex]
Hence, the base of cone is [tex]b= \frac{3V}{h} [/tex]
The Base of the cone whose volume is given is b = 3V/h.
Hence option D.
Since we know that,
A cone is a three-dimensional solid geometric shape having a circular base and a pointed edge at the top.
Here given that,
Base of cone = b
Height of cone = h
Since we also know that,
Volume of Cone = base X height / 3
⇒ V = b X h/3
⇒ 3V = b X h
⇒ b = 3V/h
Thus, the Base of the cone whose volume is given is b = 3V/h.

Prove that if a transversal is perpendicular to one of the two parallel lines, it it parallel to the other line
If a transversal is perpendicular to one of the two parallel lines, it is parallel to the other line.
Given:
Parallel lines: AB and CD
Transversal: EF
EF is perpendicular to AB
To prove: EF is parallel to CD
Since EF is perpendicular to AB, ∠AFE = 90°.
Since AB and CD are parallel, corresponding angles are equal: ∠AFE = ∠CFE.
Now, ∠CFE = 90° (since ∠AFE = 90°).
This means EF is perpendicular to CD.
By the converse of the perpendicular transversal theorem, EF is parallel to CD.

The sum of two numbers is 64 . the larger number is 18 more than the smaller number. what are the numbers?
Final answer:
To solve the problem, we use a system of equations: x + y = 64 and y = x + 18. The smaller number is found to be x = 23, and the larger number is y = 41.
Explanation:
To find the two numbers where their sum is 64 and the larger number is 18 more than the smaller number, we can set up a system of equations. Let x represent the smaller number and y represent the larger number. We have the following equations:
x + y = 64
y = x + 18
We can substitute the second equation into the first one to solve for x:
x + (x + 18) = 64
2x + 18 = 64
2x = 64 - 18
2x = 46
x = 23
Therefore, the smaller number is 23, and the larger number is:
y = x + 18
y = 23 + 18
y = 41
Hence, the two numbers are 23 and 41.
What are four different ways of representing functions? how can you tell if a relationship is a function?
Functions can be represented verbally, algebraically, graphically, and numerically. A relationship is a function when for every input, there is exactly one output which is described by the vertical line test. Graphs for different types of functions vary in shape.
Explanation:Functions can be represented in four various ways: verbally, algebraically, graphically, and numerically. For instance, verbal representation uses words to describe the function. Algebraically, we express the function via an equation. Graphically, we visually represent the function through graphs. Numerically, we represent the function using a table.
A relationship is a function if for every input, there is exactly one output. In a graph, this corresponds to an instance where a vertical line drawn anywhere on the graph would intersect it at only one point. This is also known as the vertical line test.
Examples of different types of functions graphically could include (a) a linear graph, showing a straight line, (b) a quadratic graph, parabolic in shape, (c) an inverse graph, where y decreases as x increases, and (d) an exponential graph, where the rate of growth is proportional to the function's current value.

Michael breeds chickens and ducks. Last month, he sold 505050 chickens and 303030 ducks for \$550$550dollar sign, 550. This month, he sold 444444 chickens and 363636 ducks for \$532$532dollar sign, 532. How much does a chicken cost, and how much does a duck cost?
The price of a single chicken is $8 and the price of a single duck is $5 and this can be determine by forming the linear equation in two variables.
Given :
Michael sold last month, 50 chickens and 30 ducks for $550.This month, he sold 44 chickens and 36 ducks for $532.Let the price of single chicken be 'a' and the price of single duck be 'b'. Then the linear equation will be:
[tex]50a + 30b = 550[/tex] --- (1)
[tex]44a + 36b = 532[/tex] --- (2)
Now, solve the equation (1) for 'b'.
[tex]b = \dfrac{550-50a}{30}[/tex]
[tex]b = \dfrac{55}{3}-\dfrac{5a}{3}[/tex] ---- (3)
Now, put the value of 'b' in equation (2).
[tex]44a+36\left(\dfrac{55}{3}-\dfrac{5a}{3}\right) = 532[/tex]
[tex]44a+660-60a=532[/tex]
128 = 16a
a = 8
Now, put the value of a in equation (3).
[tex]b = \dfrac{55}{3}-\dfrac{5\times 8}{3}[/tex]
b = 5
The price of a single chicken is $8 and the price of a single duck is $5.

What does h(40)=1820 mean it terms of problem?!!! HELPP
Answer:
D is the correct option.
Step-by-step explanation:
In the given table, the first column is for "hours of training" and the second column is for "Monthly pay".
Now, we have to state the meaning of the term h(40)=1820.
In coordinate system we can write this as (40,1820).
Since, the first column represents "hours of training" and second column is for "Monthly pay". Hence, we can say that for 40 hours of training the monthly payment is $1820.
In other words, if the training attended by the worker is 40 hours, h/she would pay $1820.
Therefore, D is the correct option.
