Answer:
The median of the data set:
6, 15, 30, 45, 47, 49
The middle numbers are 30 and 45 so
You have to do 30 + 45
= 75
Then do 75 ÷ 2
= 37.5
The mean of the data set:
47, 15, 6, 49, 45, 30 (add them all)
= 192
Then divide 192 by 6 (because there are 6 numbers)
192 ÷ 6
= 32
So the median is 37.5 and the mean is 32.

Answer:
86,164.2 seconds
Step-by-step explanation:
There are 60 seconds in a minute, 60 minutes in an hour. Every hour has 3600 seconds. Multiply that by 23.
23×3600=82,800
multiply 60 by 56 for the seconds in the 56 minutes.
60×56=3360
add 82800+3360+4.2= 86,164.2
<span>Simplifying
f(x) = 3x + -14
Multiply f * x
fx = 3x + -14
Reorder the terms:
fx = -14 + 3x
Solving
fx = -14 + 3x
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Divide each side by 'x'.
f = -14x-1 + 3
Simplifying
f = -14x-1 + 3
Reorder the terms:
f = 3 + -14x<span>-1</span></span>
Answer:
x > 64
therefore, 65 and 66 both apply
Step-by-step explanation:
> 8
square each side to get:
x > 64
I first found the slope of the line graphed. So i took 2 points and found the slope. They were (2,0) and (0,-3). The slope was 3/2. I then flipped it and added a negative because your looking for the perpendicular line. That was -2/3.
I took the formula y1-y=m(x1-x) and put in -2/3 as m and y1 as 2 and x1 as -1. You plug those into the equation and solve for y.
I got B for the answer
Hope this helps!
