Answer:
b = 
Step-by-step explanation:
To clear the radicals square both sides
= 
( cross- multiply )
(6 - a)(8 + b) = b - 7 ← expand factors on left using FOIL
48 + 6b - 8a - ab = b - 7 ( subtract 48 from both sides )
6b - 8a - ab = b - 55 ( add 8a to both sides )
6b - ab = b - 55 + 8a ( subtract b from both sides )
6b - ab - b = 8a - 55, that is
5b - ab = 8a - 55 ← factor out b from each term on the left side )
b(5 - a) = 8a - 55 ← divide both sides by (5 - a)
b =
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.
