Rosa throws a ball. The equation d = −t^2 + 4t + 5 represents the path taken by Rosa's ball where d is the height of the ball (in feet) after t seconds. How long was the ball in the air?
A. 1 second
B. 4 seconds
C. 5 seconds
D. 9 seconds
Answers
Answer:
B
Step-by-step explanation:
-t²+4t+5=0
t²-4t-5=0
t²-5t+t-5=0
t(t-5)+1(t-5)=0
(t-5)(t+1)=0
t=5,-1
when t=0,d=5
actual time it it is in air=5-1=4 seconds.

What is the best way of choosing a sample to statistically represent a population? Why? What is a biased sample? How can biased sampling affect the statistical study of a population?
Search the Internet and give two or more real-world examples of biased sampling leading to unexpected or unfavorable outcomes. In each case, how could the sample have been improved to make a more accurate inference about the population?
Answers
Answer: In random sampling, the whole population should have an equal chance of being chosen.
Step-by-step explanation:
In a simple random sample, every member of the population has an equal chance of being selected.
Your sampling frame should include the whole population. To conduct this type of sampling, you can use tools like random number generators or other techniques that are based entirely on chance.
Biased sample
A sample is biased if individuals or groups from the population are not represented in the sample.
In statistics, sampling bias is a bias in which a sample is collected in such a way that some members of the intended population have a lower or higher sampling probability than others.
Affects
It affects the internal validity of an analysis by leading to inaccurate estimation of relationships between variables. It also can affect the external validity of an analysis because the results from a biased sample may not generalize to the population.
Sampling is one of the procedure to get information about population. The best way to choose a sample representing a population is simple random sampling.
Why do we do sampling?We do sampling so that we don't have to work on entire population of items but only on that sample in a way that we can predict information about population.
Most of the times, it isn't possible in real world to work on entire populations. Samples come out for rescue by assumptions that they will have some properties of the population pertained in them.
Thus, the sample should be taken out such that it includes data of the population as much as it can in unbiased way so as to imitate population. (assuming that we want the sample to contain the summary of the population).
What is simple random sampling?If the sampling is done from the population randomly, without any other rule, then such sampling is called simple random sampling. Items are selected in a fixed size, all randomly.
What is stratified sampling?Sampling which is done by taking the main population divided in categories(called strata), then such sampling from stratas (sub-parts of the population) is called stratified sampling.
What is systematic random sampling?In this type of sampling, starting of the sampling is done randomly, but then rest of the samples are collected by an order. Like for example, first point is selected randomly, then all points are selected that they are equidistant from each other in the population.
What is convenience sampling?The word "convenience" summarizes this sampling. It is done in a way that those values from population are sampled which are in convenience with the researcher. Like if some random picking is to be done from beads spread on the ground, then the researcher picking those beads which are closer to him.
Convenience sampling and stratified sampling are biased, as convenience sampling is leaving a good amount of population untouched, and stratified sampling is taking about sub-parts of the population.
The systematic random sampling is not good in those cases where population doesn't contain variation equally, and we might end up doing systematic sampling in that region which is biased than other regions.
The best sampling is simple random sampling, as it is randomly picking data values from the population, so is most probable to get the properties of the population(the more you're lost, the more probable you're to get to new paths). If sample size is large enough, this sampling comes out as best sampling method, in context of summarizing the information of the population, as almost all of the properties of the population is covered by values obtained during simple random sampling.
Thus, the best way to choose a sample representing a population is simple random sampling. (assuming that we want to summarize the population).

Answer:
The mode cannot be determined.
Step-by-step explanation:
The reason it cannot be determined is because there is no common value since they all appear just once.
Answer:
J. The mode cannot be determined.
Step-by-step explanation:
Mode cannot be directly examined with a box & whisker plot such as this. The nature of this sort of representation just doesn't make it possible.
To find mode, the ideal way is to set the data of numbers from least to greatest (in order), then examine which numbers shows up the most.
Fun fact: Another great way to represent the mode is by using a DOT Plot; this is where you plot each number based on how many times it shows up on a graph. The number with the most marks is the mode because that number is what shows up most in the data.
Provided in the attachment is an example of a box plot; of which the mode is 100 as it has the most marks.
which vaule is farthest away form 0 on the number line -16, 15.5, |15|, |16.5|

EXPLANATION.
the farthest away number on the number line is the greatest number. (don’t worry about - its the same distance on left and right of the number line)
So if we look at the numbers it is clear that 16.5 is the greatest number. meaning it is the farthest from 0.
What is the value of _a_ in the equation below?
2a + 3 = 4a + 5
Answers
Step-by-step explanation:
hope it is helpful to you
Step-by-step
Simplifying 2a + 3 = 4a + 5
Reorder the terms: 3 + 2a = 4a + 5
Reorder the terms: 3 + 2a = 5 + 4a
Solving 3 + 2a = 5 + 4a
Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right.
Add '-4a' to each side of the equation. 3 + 2a + -4a = 5 + 4a + -4a
Combine like terms: 2a + -4a = -2a 3 + -2a = 5 + 4a + -4a Combine like terms: 4a + -4a = 0 3 + -2a = 5 + 0 3 + -2a = 5 Add '-3' to each side of the equation. 3 + -3 + -2a = 5 + -3 Combine like terms: 3 + -3 = 0 0 + -2a = 5 + -3 -2a = 5 + -3 Combine like terms: 5 + -3 = 2 -2a = 2 Divide each side by '-2'. a = -1 Simplifying a = -1
Which statement about the net is true?
A. The net can be folded to form a pyramid because at least one of the faces is a triangle.
B. The net can be folded to form a pyramid because more than one of the faces is a triangle.
C. The net cannot be folded to form a pyramid because one of the faces is a rectangle.
D. The net cannot be folded to form a pyramid because the faces that are not a base are not all triangles.
Answers
The statement A is true. The net can be folded to form a pyramid because at least one of the faces is a triangle.
In this problem, the net consists of four rectangles and two triangles, which can be folded to form a pyramid. The two triangles and one pair of adjacent rectangles form the lateral faces of the pyramid,while the other pair of adjacent rectangles form the base.
however, at least one of the faces of the pyramid must be a triangle,which is true for the lateral faces in this case. Therefore, statement A is true and the net can be folded to form a pyramid.

At a school, each class period is 3/4 hour long. If there are 6 hours of class time in a school day, how many class periods are there?
Answers
Answer:
2 im thinking this so tell me if i got it wrong
Step-by-step explanation:
There are 8 class periods in total in the entire school day.
According to the question,
each class takes 3/4 hrs i.e., 3/4 hrs per class
and total hours of class in a day = 6 hrs
Therefore, to identify the number of classes in a day we divide the total hours of class in a day with the time of each class. These can be shown as follows
= 6 hrs / (3/4) hrs/class
= 6 ×4/3 hrs×class/hrs (units)
= 2 × 4 class
= 8 class periods
Therefore, the total no. of class periods are 8.
