Answer:

D. The new box plot will be positively skewed.

Step-by-step explanation:

We have been given a box plot which represents the the heights (in feet) of a sample of pine trees.

We are asked to determine that affect of adding a pine tree that is 140 feet tall to the sample.

We can see from our box plot that the tallest pine tree is 75 feet and 140 is approximately 2 times greater than 75.

After adding the a tree that is 140 feet tall, the maximum height will be 140 and our right whisker will be at point 140.

Since we know that for a positive skewed data, the tail of the distribution is longer on the right hand side.

As 140 is a extreme positive outlier for our given data set, therefore, after adding a tree that is 140 feet tall our box plot will be positively skewed and option D is the correct choice.

The ratio of youths to adults at a skating rink is 13:7. What percent of these people are youths?

lara31 [8.8K]

The percentage of people at the scathing ring that are Youth is 65%. You would have to add 13 + 7, to get 20. Then you do 100 percent divided by 20 to get 5. Finally, you would do 5 times 13 to reach 65%.

Hey there, Selenawebb0418!

If you look at the table, you can see that the plant grows 2 centimeters (I'm assuming it's centimeters) every 3 days.
So, the rate of the plant should be $\frac{2}{3}$ cm per day.

Thank you for using Brainly.
See you soon!

9.) Find the following antiderivative

IrinaVladis [17]

Let u = 5x+1. Then du = 5·dx, and your integral is

$\displaystyle\frac{1}{5}\int{\frac{5}{5x+1}}\, dx=\frac{1}{5}\int{\frac{1}{u}} \, du}\\\\ =\frac{1}{5}\ln(u)=\frac{1}{5}\ln(5x+1)$
