The range of a data set is the difference between the largest and the smallest value in the set.
Here the range is: r = 62 - 25 = 35
Answer:
Step-by-step explanation: 1/4 is 0.25 so 0.25 X 18 = 4.5 so then 18X 5.15 = 81
Answer:

Step-by-step explanation:
(3x² + 4x + 4)(2x - 4)
The easiest method is probably to use long multiplication.
3x² + 4x + 4
<u>2x - 4 </u>
6x³ + 8x² + 8x
<u> - 12x² - 16x - 16</u>
6x³ - 4x² - 8x -16

The function is odd if you can replace every x with -x and get the oposite equation
example
if you replace x with -x in y=x^3, then you get -x^3, so therefor the functin is odd
so
replace x with -x
a. we get x^3+4, nope
b. we get -2x^3, yep
c. we get x^4-9, nope
d. we get x^4-4x, nope
answer is B
