Teri and Lee are playing a game that consists of consists of spinning a spinner with eight equal spaces numbered 1 through 8, and then flipping two coins at the same time.
Terri wins 10 points if the spin is greater than 5 and the coins are different (one head and one tail).
Lee wins 15 points if the spin is an even number and the coins are both tails.
Is the game is fair or unfair? Why?
A.The game is not fair, because Terri’s expected value is 10(4/8)(2/4)=2.5 and Lee’s expected value is 15(4/8)(1/4)=1.875.
B.The game is fair, because Terri’s expected value is 10(3/8)(2/4)=1.875 and Lee’s expected value is 15(4/8)(1/4)=1.875.
C.The game is not fair, because Terri’s expected value is 10(38)(13)=1.25 and Lee’s expected value is 15(4/8)(1/3)=2.5.
Answer:
B. The game is fair, because Terri’s expected value is 10(3/8)(2/4)=1.875 and Lee’s expected value is 15(4/8)(1/4)=1.875.Step-by-step explanation:

-2x - 3(2x - 4) = 4(x – 6)
3(x - 2) = x + 2x - 5
Answer:
x = 3
No Solution
Step-by-step explanation:
-2x - 3(2x - 4) = 4(x – 6) this means x would equal 3 because if you isolate the variable by dividing each side by factors that don't contain the variable.
3(x - 2) = x + 2x - 5 would have no solution because there are no values of x that make the equation true.

6. A set of data points has a correlation coefficient r = -0.86. Your friend claims
that because the correlation coefficient is close to -1, it is reasonable to use the
line of best fit to make predictions. Is your friend correct? Explain your reasoning.
Answer:
Yes
Step-by-step explanation:
The line of best fit is used in linear regression models to make predictions, the line of best fit gives the relationship between the dependent and independent variables by obtaining the Coefficient of correlation. The Coefficient of correlation is a value which ranges from - 1 to 1. With values close to either - 1 or 1 depicting a strong negative and positive relationship respectively. Hence, with a correlation Coefficient of - 0.86, which signifies a strong negative relationship, then we can go ahead and make prediction using the model.

A weather balloon is launched in Texas from an altitude of 240 feet above sea level. If the balloon rises at a constant rate of 65 feet per

First off there is not any choices, second off the answer is it would take
165.5 minutes
It will take the balloon 165 minutes 30 seconds to reach an altitude of 11,000
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, A weather balloon is launched in Texas from an altitude of 240 feet above sea level, and the balloon rises at a constant rate of 65 feet per minute.
Let the height of the balloon is h(t) where t represents time in minutes.
∴ The function that represents the height of the balloon at any point of time is h(t) = 65t + 240.
So, time required to reach the balloon an altitude of 11,000 feet is,
11000 = 65t + 240.
65t = 11000 = 240.
65t = 10760.
t = 10760/65.
t = 165.5 minutes or 165 minutes 30 seconds.

1. Brand A scooter has a top speed that goes 2 miles per hour faster than Brand B. If after 3 hours, Brand A scooter traveled 24 miles at its top speed, at what rate did Brand B scooter travel at its top speed if it traveled the same distance? Write an equation to determine the solution. Identify the if-then moves used in your solution.
Answer:
6 miles/hr
Step-by-step explanation:
Given:
Top speed of Brand A scooter goes 2 miles per hour faster than Brand B.
Distance traveled by brand A scooter on its top speed in 3 hours = 24 miles
To find:
The rate at which brand B traveled the same distance at its top speed ?
Solution:
Let the top speed/rate of brand B scooter = [tex]x[/tex] miles/hr
According to question:
Top speed/rate of brand A scooter = [tex]x+2[/tex] miles/hr
Formula:
[tex]Distance = Speed \times Time[/tex]
Distance is given to be equal to 24 miles:
24 = ([tex]x+2[/tex]) [tex]\times 3[/tex] ...... (1)
Solving the above equation by first dividing the equation on both sides with 3:
[tex]\dfrac{24}{3} = \dfrac{(x+2)\times 3}{3}\\\Rightarrow 8 = (x+2)[/tex]
Now subtracting 2 from both the sides:
[tex]\Rightarrow 8-2=x+2-2\\\Rightarrow x=6\ miles/hr[/tex]
Therefore, the answer is:
Top speed of scooter B is 6 miles/hr.
The if-then moves used to solve the equation (1) are:
Dividing by a non zero number on both sides, then subtracting a number on both sides.
Forty Percent of the thirty students in the class are boys. How many girls are in the class? PLEASE EXPLAIN!!!
Answer:
18
Step-by-step explanation:
If forty percent of the class is boys, then sixty percent of the class is girls. So that means you must multiply .6 by 30 which will give you your answer of 18. .6 is a decimal form of 60%
The number of girls in the class is 60% or 18 girls
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
