Answer:
n = -2
Step-by-step explanation:
6(2n - 3) - 2(6n + 1) = 10n
multiply the brackets
6*2n - 6*3 - 2*6n - 2*1 = 10n
12n - 18 - 12n - 2 = 10n
add or subtract the like terms
0 - 20 = 10n
shift 10 to the right hand side .REmember when u shift multiplication changes to division.
-20 / 10 = n
-2 = n
The answer is 8x+2. i hope this was helpful
Answer:
chances chances of happening = 0.0119
Step-by-step explanation:
given data
bet = $5
independent fair games = 50
solution
we will think game as the normal distribution
so here mean is will be
mean =
mean = 25
and standard deviation will be
standard deviation =
standard deviation = 3.536
so
we have to lose 33 out of 50 time for lose more than $75
so as chance of doing things z score is
z score =
z score = 2.26
so from z table
chances chances of this happening = 0.0119

Answer: 2072.4 square cm</h3>
===============================================================
Explanation:
If you used scissors to cut a vertical slice down the lampshade, then it can be unrolled to form a rectangle.
The horizontal portion of this rectangle is the distance around the circle, which is the perimeter of the circle, or the circumference. That's C = 2pi*r. Check out the diagram below to see what I mean.
The diagram shows that the diameter is 20 cm, so the radius is half that at 20/2 = 10 cm.
The circumference is C = 2*pi*r = 2*pi*10 = 20pi cm exactly
The height of the rectangle is the height of the cylinder, which is h = 30 as shown in the diagram.
The area of the rectangle is length*height = (20pi)*(30) = 600pi square cm exactly.
If we were to use something like pi = 3.14, then its approximate area is 600*pi = 600*3.14 = 1884 square cm
Let's bump this up by 10%. To do so, we'll multiply by 1.10
1.10*1884 = 2072.4
I^22 equals to -1 since i^2 is negative one
