Step-by-step explanation:
There are 12 games in the population. You need to use a random number generator to choose 2 of these games.
RandomSample[{1,2,3,4,5,6,7,8,9,10,11,12},2]
Let's say the first sample you get is {1,5}. That corresponds to game times of 8 minutes and 7 minutes. The mean game time for that sample is 7.5 minutes. So the first row in your table would be:
![\left[\begin{array}{ccc}Sample&List\ of\ Game\ Times&Mean\ Game\ Time\\1&8,7&7.5\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7DSample%26List%5C%20of%5C%20Game%5C%20Times%26Mean%5C%20Game%5C%20Time%5C%5C1%268%2C7%267.5%5Cend%7Barray%7D%5Cright%5D)
Answer:
23
Step-by-step explanation:
x+x+1=x+2=72
3x+3=72
3x=69
x=23
23+24+25=72
Answer:
y = -1/2x + 13/2
Step-by-step explanation:
The slope of a line that is perpendicular to a line will be a negative reciprocal. When you rewrite 2x-7=8 into slope-intercept form, you get y=2x-8. The negative reciprocal of the slope 2x is -1/2x. There is only one option with this slope. If you're still not sure then you can use a graphing calculator to check this. An online one would be desmos
Answer:
ans is C. 63 ft.
Step-by-step explanation:
u, tree base n tree top form a right-angle triangle w/
an angle of 49deg
adjacent side = 55'
opposite side = tree height
using trig fn tan(angle)=opposite/adjacent
tan(49deg)=tree height/55'
tree height=55'*tan(49deg)
=63.27' rounding to 63 ft.
The x is the diagonal side of the triangle. Y and z combine to make the whole bottom side of the whole triangle.
