Answer:
The answer is 48a-6b-14
Step-by-step explantion:
simplify by combining liketerms:
-6- 2b•3 -6a+ 10a• 3-16÷ 2- 4 • -6a
-6-6b-6a+30a -8+24a
48a-6b-14
Good luck!
Answer:
The answer is Diameter.
Step-by-step explanation:
A Diameter is a straight line passing through a point of a circle.
The confidence interval is
. This means that we can be 99% confident that the mean number of books people read lies between 9.15 and 11.85.
To find the confidence interval, we first find the z-score associated with it:
Convert 99% to a decimal: 0.99
Subtract from 1: 1-0.99=0.01
Divide by 2: 0.01/2 = 0.005
Subtract from 1: 1-0.005 = 0.995
Using a z-table (http://www.z-table.com) we see that this is associated with a z-score between 2.57 and 2.58. Since both are equally far from this value we will use 2.575.
We calculate the margin of error using
This means that the confidence interval is
The lower limit is given by 10.5-1.35 = 9.15.
The upper limit is given by 10.5+1.35 = 11.85
There is a total of 24 students in the class.
The probability of choosing a girl is 16/24. Which reduces down to 2/3 or 66%.
The probability of choosing a boy is 8/24. Which reduces to 1/3 or 33%.
So the student has a 66% chance of choosing a girl and 33% chance for a boy.
Answer:
The volume of cone z has the same base area as cylinder y but its height is 3 times the height of cylinder y have the same volume.
Step-by-step explanation:
The volume of a cylinder having base area 'A' and height 'H' is given by V = AH, and the volume of a cone having the same base area as the cylinder i.e. A and height 3 times the height of the cylinder i.e. 3H is given by .
So, V = V'
Hence, the volume of cone z has the same base area as cylinder y but its height is 3 times the height of cylinder y have the same volume. (Answer)
