Answer: The correct answer would be 0.58.
The value of r of a set of data tells us how close the values are to the line of regression of the data. If you add in an outlier, it would make the overall r value of the points further from the line. In other words, it would go further from 1.
In this case, our initial r value was positive, so it makes sense to keep it positive. 0.58 would be the best choice.
e is a special number, so you would need to use a calculator to solve this.
a) replace t in the equation with 5 ( 2005 - 2000 = 5 years)
A = 16.6e^0.0457*5 = 20.86 million Round to nearest tenth = 20.9 million.
b) replace A with 23.3 and solve for t:
23.3 = 16.6e^0.0457*t
Divide both sides by 16.6:
1.4036 = e^0.0457t
Take the natural logarithm of both sides:
0.0457t = LN(1.4036)
Divide both sides by 0.457:
t = LN(1.4036)/0.0457
t = 7.419 years, rounded to nearest tenth = 7.4 years.
I need points can you give me some of your points
Answer:
There are 1,037,158,320 ways to choose a committee of 18 among 33 students.
There are 4,939,200 ways to choose 5 freshmen from 7, 6 sophomores from 8, 4 juniors from 8, and 3 seniors from 10.
Step-by-step explanation:
33!/18!15! = 1,037,158,320
7!/5!2! * 8!/6!2! * 8!/4!4! * 10!/7!3!
= 7*3 * 7*4 * 7*5*2 * 10*4*3 = 4,939,200
