7. The relation y = 7x + 35 represents the monthly cost y (in dollars) of a group of
x members joining the fitness club.
a. Identify the independent and dependent variables.
b. Your group has enough money for up to six members to join the fitness club.
Find the domain and range of the function.
c. Is the relation a function?
Answers and Step-by-step explanation:
a. The independent variable is the variable being manually changed by the experimenter. The dependent variable is the variable being affected by the independent variable. X (members joining the fitness club) is the independent variable. Y (total monthly cost) is the dependent variable.
b. The domain is 6, because x is always the domain. The range is 77, because Y is always the range. You plug in 6 (the domain which is x), and get 77.
c. Yes, this relation is a function. Relations are only not functions when one singular input (domain) goes to 2 outputs (range).
A domain can not have multiple ranges. A range can have multiple domains though.
The y is the dependent variable and the x is the independent variable, in the equation y = 7x + 35, The domain is 6 and the range is 77 for the given equation. Yes, it is a function.
What is an equation?In other terms, it is a mathematical statement stating that "this is equivalent to that." It appears to be a mathematical expression on the left, an equal sign in the center, and a mathematical expression on the right.
Given:
y = 7x + 35, x members joining the fitness club and y is cost.
(a) As you can see from the equation, y depends on the value of x,
(b) Calculate the amount of x = 6 (as given)
y = 7 × 6 + 35
y = 42 + 35
y = $77
The domain of the function is 6 and the range is 77.
(c) Yes, as we put the values in x, y also changes, so it is a function.

A meeting takes place between a diplomat
and fourteen government officials.
However, four of the officials are actually
spies. If the diplomat gives secret
information to ten of the attendees at
random, what is the probability that no
secret information was given to the spies?
Answer:
The number of ways to choose 10 people out of 14 people is given by 14C10 which is read "14 choose 10"
Only 1 of these combinations will result in no information being given to any of the 4 spies.
Can you figure out the probability from these 2 facts?

x ≈ 50.8°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin x = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{JK}{IK}[/tex] = [tex]\frac{6.2}{8}[/tex] , then
x = [tex]sin^{-1}[/tex] ([tex]\frac{6.2}{8}[/tex] ) ≈ 50.8° ( to the nearest tenth )
A contractor purchases 5 dozen pairs of padded work gloves for $70.80. she incorrectly calculates the unit price as $14.16 per pair for the expense report. What is the correct unit prise? What is the error?
Answer:
1 dozen = 12 units
7 dozen = 12 × 7 = 84 units
Correct unit price = 103.32 ÷ 84 = $1.23
The contractor's unit price incorrect because he did 103.32 ÷ 7 dozen.
The price he calculated is for the price for 1 dozen, not 1 unit

The product of three consecutive integers is 3360. What is the sum of the three integers?
Step-by-step explanation:
let the integer be x .
three consecutive integers : x, x+1, x+2.
according to the problem,.
Let the first of the 3 consecutive numbers be X.
Therefore the second number is (X + 1)
The third number is therefore (X + 2)
The product of the 3 consecutive numbers is:
( X )( X + 1 )( X + 2 ) = 3360 Equation( 1 )
Expanding Equation ( 1 ) gives
X³ + 3X² + 2X - 3360 = 0 Equation (2)
Solve Equation (2 ) which gives the following values for X
X1 = 14
X2 = - 8.5 + i (12.951834)
X3 = - 8.5 - i (12.951834).
the numbers are 14,15,16.
sum is 14+15+16 = 45.

The map shows the location of a mall, library, and school in a city:
Coordinate grid shown from negative 14 to positive 14 on x axis at intervals of 2, and negative 10 to positive 10 on y axis at intervals of 2. A triangle is shown with vertices labeled Library, Mall, and School. Library is the ordered pair negative 14, 6, Mall is the ordered pair 10, 6, and School is the ordered pair 10 and negative 4.
Britney traveled from the school to the mall and then from the mall to the library. Alice traveled directly from the school to the library. How many more miles did Britney travel than Alice? (1 point)
8 miles
9 miles
10 miles
12 miles
The direct distance from the school to the library, travelled by Alice can be
found using Pythagoras's theorem.
The number of miles Britney travelled more than Alice is; 8 miles
Reason:
The distance, d, between points given their coordinates, (x₁, y₁), (x₂, y₂) can
be found with the formula;
[tex]d = \sqrt{\left (x_{2}-x_{1} \right )^{2}+\left (y_{2}-y_{1} \right )^{2}}[/tex]
The above formula can be obtained using Pythagoras's theorem.
The distances travelled by Britney are;
Distance from the school to the mall = [tex]\sqrt{(10 - 10)^2 + (6 - (-4))^2}[/tex] = 10
Distance from the mall to the library = [tex]\sqrt{(-14 - 10)^2 + (6 - 6)^2}[/tex] = 24
Total distance travelled by Britney = 24 miles + 10 miles = 34 miles
The distance travelled by Alice is from the school to the library, which
gives; Alice's distance = [tex]\sqrt{(10 - (-14))^2 + (-4 - 6)^2}[/tex] = 26
Distance travelled by Alice from the school to the library is 26 miles
The number of miles more Britney traveled is 34 miles - 26 miles = 8 miles
Therefore;
Britney traveled 8 miles more than Alice
