Answer:
7.8
Step-by-step explanation:
distance formula : 
where the x and y values are derived from the given points
here the given points are (11,3) and (6,9)
<u>assigning variables</u>
(x1,y1) = (11,3) so x1 = 11 and y1 = 3
(x2,y2) = (6,9) so x2 = 6 and y2 = 9
<u>plugging in values into formula</u>
recall formula
==> plug in x1 = 11 , y1 = 3 , x2 = 6 and y2 = 9
==> subtract values in parenthesis
==> evaluate exponents
==> add 25 and 36
( approximately )
Here we are going to use the equation y=15x2+3x+56.
x=0 in 2,000 so x=10 in 2010.
Substitute 10 for x.
After this we have the answer: D. $1,586
The best measure of center for a set of data is the median value.
To find the median list the values from
Smallest to largest:
0, 0, 1, 1, 2,2, 2, 14
Since there is an even number of values, find the middle two numbers, add them together and divide by 2:
1+2 = 3
3/2 = 1.5
The answer is median 1.5
Answer:
the number 2 for area is 27 cm3 (cubic centimeters) then number 3 for area is 6.25 cm3 (cubic centimeters)
Step-by-step explanation:
pretty sure sorry if wrong!
Answer: b
Step-by-step explanation:
Radius = 9 inches, Pi= 3.14
Circumference = 2 x pi x radius = 2 x (3.14) x 9 = 56.52
Area = pi x radius x radius = (3.14) x 9 x 9 = 254.34
