Answers
Answer:
C and D
Step-by-step explanation:
The Middles were the same length and the side of the alligator are slightly longer.
The correct options are:
C. Center-- The crocodiles have a greater median length than the alligators.
D. Spreads-- The lengths of the alligators are more spread out.
Step-by-step explanation:Median of the data--
The median is the central tendency of the data and it always exist in the middle of the data.
By looking at the data.
We observe that the Median of the data :
Crocodile lie at : 17
and that of the alligator lie at : 9
Hence, the median for the crocodile is more than for the alligators.
Spread--
The spread in the data means how far the data points are from the center of the data i.e. mean or median.
By looking at the data crocodile we observe that all the data points are close to the median.
whereas in the data alligator one of the data point is far from the median.
Hence, the spread in case of alligator is more as compared to that of crocodiles.

Based on the latest census there are 9860 students in a population of 62400 people. What percent of the total population is students?
Answers
Answer: 15.80%
Step-by-step explanation:
Given: Total population=62400
The total number of students=9860
To find the percent of the total population is students, we need to divide total population by total number of students and then multiply with 100, we get
The percent of the total population is students=[tex]\frac{9860}{62400}\times100[/tex]
[tex]=\frac{9860}{624}\\=15.80\%[/tex]
Hence, the percent of the total population is students is 15.80%.
Final answer:
To calculate the percentage of the total population that are students, divide the number of students (9860) by the total population (62400) and multiply by 100, resulting in approximately 15.8%.
Explanation:
To find the percentage of the population that are students, we use a simple formula where we divide the number of students by the total population and then multiply the result by 100. Applying this to the given numbers:
Percentage of students = (Number of Students / Total Population) × 100
Using the numbers provided:
Percentage of students = (9860 / 62400) × 100
Percentage of students = 0.15801282 × 100
Percentage of students = 15.801282%
Therefore, approximately 15.8% of the total population is students.

733.32 x .03 = 21.9996 (round up to 22.00)
If you apply the changes below to the linear parent function, F(x)=x, what is the equation of the new function? vertically compress by 1/4 flip over the y-axis
Answers
Final answer:
The new function after applying the given transformations to the linear parent function f(x) = x, results in f(x) = -1/4x, representing a combined vertical compression and reflection about the y-axis.
Explanation:
Starting with the linear parent function f(x) = x, we need to apply two transformations: a vertical compression by 1/4 and then a reflection over the y-axis. Applying a vertical compression by 1/4 means we multiply the output by 1/4, resulting in f(x) = (1/4)x.
To reflect the function across the y-axis, we replace x with -x, which gives us the new function f(x) = (1/4)(-x) or, simplified, f(x) = -1/4x. Therefore, the equation of the transformed function is f(x) = -1/4x.
One characteristic of all linear functions is that they change by
1) equal factors over equal intervals
2) unequal factors over equal intervals
3) equal differences over equal intervals
4) unequal differences over equal intervals
Answers
The correct answer is:
3) equal differences over equal intervals
Linear functions exhibit a consistent rate of change over equal intervals, leading to equal differences between successive values of the function. This characteristic is fundamental to understanding linearity.
When graphed, linear functions form straight lines, and the slope of the line represents the rate of change or the coefficient of the independent variable. Regardless of the specific values of the function, the change in output over any fixed change in input (interval) remains constant.
This property is referred to as having equal differences over equal intervals. It contrasts with non-linear functions, where the rate of change varies across the function's domain, resulting in unequal differences over equal intervals.
Identifying and understanding this characteristic helps in recognizing linear relationships and interpreting their behavior in various contexts, from mathematics to real-world applications.
HELP ASAP!!! WILL GIVE BRAINLIEST!!!!!The equation y = mx + b is used to express the equation of a line. Which solution is a correct way to solve this equation for x in terms of y?
Answers
To solve the equation y = mx + b for x, subtract b from both sides and then divide by m, resulting in x = (y - b) / m.
Explanation:To solve the equation y = mx + b for x in terms of y, you need to isolate x on one side of the equation. Here’s how you can do it step by step:
Start with the original equation y = mx + b.Subtract b from both sides of the equation to get y - b = mx.Divide both sides by m (assuming m ≠ 0) to solve for x which gives us (y - b) / m = x.Therefore, the equation solved for x in terms of y is x = (y - b) / m.

Robin is standing on the top of a 40-foot flagpole at 1 p.m. At the same time, a 4-foot child on the ground casts a shadow of length 0.8 feet. If Robin is 6 feet tall, how much longer is the shadow of the flagpole and Robin together than the shadow of the flagpole alone? Specify your answer as a decimal to the nearest tenth.
Answers
Answer:
1.2 ft
Step-by-step explanation:
We can use ratio's to solve this problem. Put the item on top, and the shadow on the bottom
40 ft flagpole 4 ft child
--------------------- = --------------------
x ft shadow .8 ft shadow
Using cross products
40 * .8 = 4x
32 = 4x
Divide each side by 4
32/4 = 4x/4
8 = x
The flag pole casts an 8 ft shadow
The question asks how much longer is the shadow of the flagpole and Robin than the flagpole? In other words, how long is Robins shadow
40 ft flagpole 6ft Robin
--------------------- = --------------------
8 ft shadow x ft shadow
Using cross products
40 *x = 6*8
40x = 48
Divide by 40
40x/40 = 48/40
x = 1.2
Answer:
1.2
Step-by-step explanation:
The height of an object and the length of its shadow are directly proportional. Let h be the height of an object and s be the length of its shadow. From the information about the child, we have h/s = 4/(0.8) = 5. The flagpole with Robin on top has a height of 46 feet. Suppose its shadow has length x. Solving the equation 46/x = 5 for x gives us x = 46/5 = 9.2 feet. The flagpole alone is 40 feet tall. Suppose its shadow has length $y.$ Then, we must have 40/y = 5. Solving this equation gives y=8 feet. So, the difference in shadow lengths is 9.2 -8= 1.2
Solve for x. Please show work.

A recipe for beef stew requires 1 and 3/4th pounds of meat.You are making 6 and 1/2 batches of the recipe. how much meat do you need?
Answers
Answer:
11.375 pounds
Step-by-step explanation:
1.75 * 6.5 = 11.375
11 and 3/8 pounds of meat are required in total.
The student is asking a multiplication problem that involves fractions. To find the amount of meat needed, we multiply the amount of meat required for one batch by the number of batches.
Step-by-Step Calculation
First, we must convert the fractions into improper fractions to simplify calculation. The recipe requires 1 and 3/4 pounds of meat, which is
7/4 pounds (since 1 pound is 4/4 pounds, we add 3/4 pounds to get 7/4 pounds).
Next, the number of batches is 6 and 1/2, which as an improper fraction is 13/2 batches.
To find the total amount of meat required, we multiply the pounds per batch by the number of batches: (7/4) pounds x (13/2) batches = (7/4) x (13/2) = (7 x 13) / (4 x 2) = 91/8 pounds.
Finally, convert 91/8 pounds to a mixed number: 11 and 3/8 pounds of meat are required in total.

The box plots below show distribution of grades in one class on two tests.
Which measures of center and variability would be best to use when making comparisons of the two data sets?
Answers
For comparing two data sets using box plots, 'median and IQR' is the best choice as they describe the center and variability effectively, especially for skewed data. Therefore, option d is the correct answer.
When comparing two data sets using box plots, the best measures of center and variability to use are often the median and interquartile range (IQR).
The median best describes the center of a skewed distribution, as it is not affected by extreme scores, and the IQR describes the variability by measuring the spread of the middle 50 percent of the data.
Therefore, between the options provided, 'median and IQR' would be the best measures to compare the two data sets of Test 1 Grades and Test 2 Grades.
A box plot displays the minimum value, the first quartile (Q1), the median, the third quartile (Q3), and the maximum value.
The IQR is calculated by subtracting Q1 from Q3, giving us the spread for the middle 50 percent of the data. This is helpful when assessing how close the data values are to the center and how they are distributed within that range.
Therefore, option d is the correct answer.

If the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs” what is the alternate hypothesis?
Answers
Answer:
“The true mean weight of the piglets is at most 39lbs”would be the alternate hypothesis.
Step-by-step explanation:
Given that the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs”
We have to find the alternate hypothesis.
In hypothesis testing, alternate is the opposite of null hypothesis. If null hypothesis supports one statement alternate hypothesis opposes it. In other words, alternate hypothesis would be the negative of the claim of null hypothesis.
Here the null hypothesis of an experiment is “The true mean weight of the piglets is at least 39lbs”
i.e H0: [tex]x bar\geq 39 lbs[/tex]
So alternate hypothesis

Complete the point slope equation of the line through (-2,6) and (1,1)
Answers
Answer:
y-1 =( -5/3) (x-1)
Step-by-step explanation:
The point slope equation for a line is
y-y1 = m(x-x1)
where m is the slope and (x1, y1) is a point
We need to determine the slope
The formula for slope is
m = (y2-y1)/(x2-x1)
where (x1,y1) and (x2,y2) are points
m = (1-6)/(1--2)
= (1-6)/(1+2)
=-5/3
The slope is -5/3
Now we can substitute the slope into the equation for a line. We can use either point. I will use (1,1)
y-y1 = m(x-x1)
y-1 =( -5/3) (x-1)
Answer:
y-1 =( -5/3) (x-1)
Step-by-step explanation:
The point slope equation for a line is
y-y1 = m(x-x1)

We need to determine the slope
The formula for slope is
m = (y2-y1)/(x2-x1)
where (x1,y1) and (x2,y2) are points
m = (1-6)/(1--2)

=-5/3
The slope is -5/3
Now we can substitute the slope into the equation for a line. We can use either point. I will use (1,1)
y-y1 = m(x-x1)

It takes 10 people 5 days to complete a piece of work at a factory when working 2 hours a day. Working at the same pace, how many days will it take 2 people to do the same work, if they are working 5 hours a day?
Answers
Answer:
It will take 2 people 10 days to complete the task.
Step-by-step explanation:
It takes 10 people 5 days to complete a piece of work at a factory when working 2 hours a day, i.e., 10 people take 10 working hours to complete a task.
When number of people is decreased by 5 times, i.e., 10÷5=2, then the amount of working hours are increased by 5, i.e., 10×5= 50 hours.
If the 2 workers work 5 hours per day then they will require 10 days to complete the task of 50 hours.
