Answer:

348 out of 725

Step-by-step explanation:

This is a ratio question, giving us a sample that we can use to extend the number to all students.

12/25 students play a sport so we want the value of x in x/725

So:

12/25 = x/725

Cross-Multiply:

25x = 8700

Divide by 25 to get x:

348

You can also check by dividing these ratios to see if you get the same number. In this case, you do (.48).

Answer:

The measure of center would this student want his teacher to use is the

median $= {\bf 75}$

Mean $= {\bf 5}$ , Mode $={\bf 82}$ , Range $={\bf40}$ and Interquartile Range $= {\bf 32}$

Step-by-step explanation:

Given Data set $= 50,55,70,75,82,82,90$

Number of elements in data set $= 7$

To find Mean

The ‘Mean” is the average of a set of numbers.

The "Mean" is computed by adding all of the numbers in the data together and dividing by the number of elements contained in the data set.

Mean $= \frac{50 +55 +70 + 75 + 82 + 82 + 90} {7 }$

Mean $= \frac{504}{7}$

Mean $= 5$

Median

The “Median” is the middle value of a set of ordered numbers.

Therefore Median $=75$

Mode

The "Mode" for a set of data is the value that occurs most often.

It is not uncommon for a data set to have more than one mode. This happens when two or more elements occur with equal frequency in the data set.

Therefore Mode $=82$

Range

The "Range" is the difference between the largest value and smallest value in a set of data.

Range $= 90-50$

Range $= 40$

Interquartile Range

The “Interquartile Range” is the difference between smallest value and the largest value of the middle 50% of a set of data.

The "Interquartile Range" is from Q1 to Q3:

To find the interquartile range of a set of data:

The cut the list into four equal parts

. The quartiles are the “cuts”

The interquartile range is the distance between the two middle sets of data

Interquartile Range $= Q_3-Q_1$

Interquartile Range $= 82-50$

Interquartile Range $= 32$

Suppose that the weights of 5400 registered female Labrador retrievers in the United States are distributed normally with a mean

kherson [118]

I believe the normal distribution is symmetrical above and below

the mean. That tells us that in this kind of distribution, the mean

and the median are the same number ... 50% of the population

is below it, and 50% is above it.

So if the female Labs' weight actually follows a 'normal' distribution

with a mean of 62.5 lbs, then 2,700 of them weigh more than 62.5 lbs

and 2,700 of them weigh less than that.

The standard deviation doesn't matter.

A health club manager wants to determine whether the members would prefer a new sauna or a new steam room. The club surveys 50 o

Arlecino [84]

Answer:

The population is all 600 members of the health club

Explanation:

50 members were chosen out of all 600 members thereby telling us that the sample of the study/survey is 50 members while the population is all 600 members. A sample represents the population and is collected from the population to make it less tedious to study and make conclusions on the population. For example, given that the population of a study are individuals or objects of common characteristics, 50 members tell the needed story and relays the characteristics and/or definition of the whole population, thereby forming a basis to make a conclusion on the population.

Which facts are true for the graph of the function below check all that apply F(x)=log6x

REY [17]

Based on the graph of the function (F(x) = log6x), the following facts are true:

It is increasing.

The x-intercept is (1, 0).

<h3>What is a graph?</h3>

A graph is a type of chart that is used to graphically represent data on both the horizontal and vertical lines of a Cartesian coordinate i.e x-axis and y-axis.

By critically observing the graph of the function (F(x) = log6x) attached in the image below, we can infer and logically deduce that its domain and range include all real numbers that are greater than 0 (x > 0).

This ultimately implies that, the following facts are true:

It is increasing.

The x-intercept is (1, 0).
