A random group of 5 boys and a random group of 5 girls were selected to determine whether boys or girls text more. The table sho

ws the number of texts sent by each person during one day. Comparing the data sets, which inference can be made?
A) The number of texts sent by boys varies greatly.

B) The median is the best measure to use to compare the sets.

C) The outlier of 168 does not affect either the mean or median.

D) The median for the number of texts sent by boys is less than the median for the girls.

Boys: 19, 23, 26, 27, 30
Girls: 14, 17, 21, 25, 168

<h2>Answer:</h2>

The inference that can be made by the given data sets is: Option: B

B) The median is the best measure to use to compare the sets.

<h2>Step-by-step explanation:</h2>

We are given a data set for Boys and Girls as:

Boys: 19, 23, 26, 27, 30

Girls: 14, 17, 21, 25, 168

clearly we could see that there is a outlier in the data of girls i.e. 168 as it is a too high value as compared to other data values in the set.

This means that there is a greater spread in the number of texts sent by girls as compared to boys.

and data for girls have a greater variance as compared to boys.

Hence, option: A is discarded.

Also,

Median of Boys= 26

and Median for Girls = 21

This means that Median for the number of texts sent by boys is more than those by girls.

Hence, option: D is discarded.

Also we know that an outlier affect the mean and median of the data.

Hence, option: C is discarded.

We know that median of the data is the central tendency of the data and best compare the set of data.

Hence, Option: B) is the correct answer.

The cost of renting an apartment can be modeled by the function C(m)=900m+1400, where C(m) is the cost in dollars for m months o

Ahat [919]

Answer:

On the context of the problem, the slope means the total paid for every month that the apartment is rented, 900 per month in this case, while the y-intercept means the initial cost for renting the apartment, 1400 upfront in this case.

Step-by-step explanation:

This function is linear, which means that it increases at a steady rate and has the following form:

$y(x) = a*x + b$

Where "a" is the slope or the rate at which "y" changes for every change in "x". While "b" is the number at which the function crosses the "y" axis.

On the context of the problem, the slope means the total paid for every month that the apartment is rented, 900 per month in this case, while the y-intercept means the initial cost for renting the apartment, 1400 upfront in this case.

Determine whether the improper integral converges or diverges, and find the value of each that converges.

Ksju [112]

Answer:converge at $I=\frac{1}{3}$

Step-by-step explanation:

Given

Improper Integral I is given as

$I=\int^{\infty}_{3}\frac{1}{x^2}dx$

integration of $\frac{1}{x^2}$ is - $\frac{1}{x}$

$I=\left [ -\frac{1}{x}\right ]^{\infty}_3$

substituting value

$I=-\left [ \frac{1}{\infty }-\frac{1}{3}\right ]$

$I=-\left [ 0-\frac{1}{3}\right ]$

$I=\frac{1}{3}$

so the value of integral converges at $\frac{1}{3}$
