In the following problems, you will make an inference, or prediction, based on the sample from a population. Write two to three complete sentences.
1. There are 200 students in the 7th grade. The students were asked to sign up for their favorite field day activity in gym class. A sample showed that 45 students signed up for tug of war, 15 students signed up for the relay race, and five students signed up for the hula hoop contest. What can you predict about field day?
Answer:
Hope it helps
Step-by-step explanation:
I predict that most of the students that didn't sign up yet, are going to play tug of war. The 45 student that sign up for tug of war are at 22.5%, then for the relay race( 7.5 %) and hula hoop contest is 10 %. But it could change because only 65 sign up, and there 155 students left that has not sign up.

Answer:
Part A is 6, and Part B is 1-4
Step-by-step explanation:
the function F is defined by F(x) 12/x+1/2. use this formula to find the following values of the function. F(a/2)
Answer:
F([tex]\frac{a}{2}[/tex]) = [tex]\frac{24}{a} +\frac{1}{2}\\[/tex]
Step-by-step explanation:
so basically what you want to do is insert the f(x) value into the equation. What I mean by that is in this equation, since f(x) = f(a/2), you want to substitute A/2 into the equation, so you'll have [tex]\frac{12}{\frac{a}{2} }[/tex], if you can't see that, its 12/a/2. In other words, this is 12 ÷ [tex]\frac{a}{2}[/tex] , which you can also format as 12 ·[tex]\frac{2}{a}[/tex], because of the "keep, change, flip" thing. Well, you know that equation is equal to 24/a so you just have to add back the 1/2, and you have your answer!
Side Note:
I know the format is terrible, but the answer is right so please bear with me :)I know the person asking this question asked it a year ago so i'm just answering it for future usersIf i'm guessing correctly, this question originated from RSM, and I found it googling rsm problems, and my answer is correct in RSM, so if you have this same question on your RSM homework, I promise you it's rightIf you got this from RSM homework, and you have other questions about the same types, like 7abcdegi, comment, because I have those answers tooIf you have any questions about this answer, also comment, I would love to helpIf the user who asked this question is still active, I would really appreciate brainliest if you think this deserves itHope this helps!!

Can someone answer this its just boxplots :)))
Explanation:
The boxplot, aka box-and-whisker plot, is a visual way to represent summary data. Each piece of the boxplot visually tells us one of the five items of a five number summary, which are:
Min = smallest valueQ1 = first quartileMedian = middle most valueQ3 = third quartileMax = largest valueThe median is the vertical line inside the box of the boxplot. The diagram shows that the median is 25. Exactly half of the distribution is below the median, and the other half is above the median. So that means that 50% of the cars get at least 25 mpg.
The price of a cell phone model was tracked over a ten-month period. The graph shows the relationship between the price of the phone and the time.
How does part E of the graph relate to the situation?
A.
Part E represents a period when the price was not tracked.
B.
Part E represents a period when the price remained the same.
C.
Part E represents a period when the price decreased at the fastest rate.
D.
Part E represents a period when the price decreased at a slower rate than in part C.
Answer:
D
Step-by-step explanation:
Part E represents a period when the price decreased, but slower than C. C is a very steep line which means it decreased faster.
Which of these statements best describes a biased sample?
A. it is very small.
B. It is not randomly chosen.
C. It results in incorrect predictions.
D. It does not accurately represent the population.
Answer:
i think it is B
Step-by-step explanation:
bias means you have an opinion on something and you make choices on it so a biased sample would not randomly chosen
The correct option is:
D.) It does not accurately represent the population.
What is sampling?In statistical analysis, sampling is the procedure by which researchers select a specific number of observations from a larger population. The sample strategy will depend on the sort of study being done, although it may involve systematic sampling or just plain random sampling.
It is a common statistics practice, when we want to study something from a population, we find a sample, which is a group of members of this population. The sample has to be representative of the population, that is, it has to involve all of its groups. If it does not involve all the groups, it is not an accurate representation of the population, and is called biased.
Hence, option C is correct.

Answer:
C, 8.5
Step-by-step explanation:
The area of a rectangular prism is Length times Width times Height. If the volume of the tank (which is a rectangular prism) is 1360, then the L x W x H is 1360. The area of the base of the tank is determined by multiplying the Length and the Width together, so that means that L x W = 160.
Our first equation
L x W x H = 1360
Our second equation
L x W = 160
We see that 1360 divided by 160 gets us the height of the prism.
1360 / 160 = 8.5, so the answer is C
