Answer: -0.5
Step-by-step explanation:
5 + (-5.5) = -0.5 dollars
The expected return of placing this bet is -0.5 dollars.
What is probability?Probability is a number that indicates the likelihood of an event occurring. Probability is defined as the ratio of favorable outcomes to all outcomes.
To calculate the expected return of this bet, we need to consider the possible outcomes and their probabilities. There are two possible outcomes:
The Denver Dragons win with a probability of 0.5. In this case, Ivy will win 10 dollars.
The Seattle Sea Turtles win with a probability of 0.5. In this case, Ivy will lose 11 dollars.
To calculate the expected return, we multiply each outcome by its probability and sum the results.
Expected return = (0.5 x 10) + (0.5 x -11)
Expected return = 5 - 5.5
Expected return = -0.5
Therefore, the expected return of placing this bet is -0.5 dollars, which means that over the long run, Ivy can expect to lose an average of 50 cents every time she places this bet.

One shirt is represented as “y”
He ordered four shirts totaling $44
y+y+y+y =$44
Answer:
1. x = 462.30m
2. c
Step-by-step explanation:
1. Let "x" represent how much Samantha earns, and "m" represent how many months she has worked.
Because she makes $462.30 per month, if we multiply that by "m" then we will get x.
2. Kyle spend $44 on four sweaters total, which would make the total cost be evenly distributed into 4 sections.

What is a function rule?The function rule is the relationship between the input or domain and the output or range. A relation is a function if and only if there exists one value in the range for every domain value.
A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given data ,
Let the function be represented as f ( x )
Now , the value of f ( x ) is
f ( x ) = 2x + 1
The inverse of the function is calculated by taking the x coordinate and replacing it with y
So , the function now becomes
x = 2y + 1
On simplifying , we get
Subtracting 1 on both sides , we get
2y = x - 1
Divide by 2 on both sides , we get
y = ( x - 1 ) / 2
Now , replacing y with x , we get
h ( x ) = ( x - 1 ) / 2
h ( x ) = ( 1/2 )x - ( 1/2 )
Hence , the inverse of the function is h ( x ) = ( x - 1 ) / 2

Need help ASAP please--about estimate. which answer is correct. Please give me an opinion. Three students were asked to use estimation strategies to find a reasonable solution to this question: Ricky had 26 stickers before buying 7 from the store. Then he gave 8 to his sister. Estimate how many stickers he has left. From the choices below, select the student with the most reasonable solution.
a) Student A: Ricky has around 45 stickers left. Round 26 stickers to 40, 7 bought to 10, and 8 given to 5. Add 40 + 10 to get 50. Then subtract 50 − 5 to get the estimated answer of 45.
b) Student B: Ricky has around 30 stickers left. Estimate the sum of 6 from the 26 stickers plus 7 bought to be about 20. Add the 20 to the leftover 20 to get 40. Round 8 given to 10. Then subtract 40 − 10 to get the estimated answer of 30.
c) Student C: Ricky has around 10 stickers left. Estimate the sum of 6 from the 26 stickers plus 7 bought to be about 10. Add the 10 to the leftover 10 to get 20. Round 8 given to 10. Then subtract 20 − 10 to get the estimated answer of 10.

1. Forty randomly-selected members of a high school music program were asked to report the number of hours they spend practicing each week. If you were to compute the mean number of hours, would you answer be a parameter or a statistic? Explain.
===========================================================
Explanation:
The fact that we have the phrasing "randomly-selected" in there is a big clue that we are working with a sample, and not a population. If 40 people represented the population, then we wouldn't be randomly selecting anyone. Everyone would be surveyed. No random process needed. We don't need to worry about the order of those surveyed.
However, we are applying a random selection process to form this sample. A statistic is some value that measures a sample. For instance, xbar is the sample mean which is a sample statistic. The xbar value estimates mu, which is a greek letter. Mu is the population mean and a population parameter.
To remember the difference between the two terms parameter and statistic, one useful memory trick is to think of it like this:
Statistic and sample both start with sPopulation and parameter both start with pAs the name "statistics" implies, it is the study of how to estimate a population based on a sample. After gathering the sample, we compute a statistic, which in turn estimates a parameter. So that explains why your math course and textbook has that label.

Suppose one of your friends was absent from school on the day your math class learned about graphing rational numbers on the number line. Using complete sentences, explain to your friend how to graph the opposite of 6.2 on the number line.
Answer:
So i would ask this friend to draw a number line and label 6.2 on the number line. Then i would ask her if she knew what the opposite number of 6.2 is.
Yes- The number line will always continue, its indefinite. This means it can go forward or backwards. Make sure that your friend wrote 0. You always need a starting point. Then tell her to draw the tally marks forward the same way she did backwards. Locate the 6.2 and make all of the numbers negative.
