Answer:
B and C
When you divide 64000 by 2 and 480000 by 15, they all equal 32000.
Adding up all 6 probabilities gives a total of 1, which means that this is a valid distribution function. Observing that P(0) = P(5), P(1) = P(4), and P(2) = P(3), this is a symmetric distribution.
Its mean will be in the middle, which is at x = 2.5.
The standard deviation is calculated by multiplying each P(x) by the square of deviation (x - average)^2: (0.032)(0 - 2.5)^2 + (0.152)(1 - 2.5)^2 + (0.316)(2 - 2.5)^2 + (0.316)(3 - 2.5)^2 + (0.152)(4 - 2.5)^2 + (0.032)(5 - 2.5)^2 = 1.242, then taking the square root: sqrt(1.242) = 1.1145.
Hello!
First of all, let's undo the square roots by squaring both sides.
6x+2=9x-8
We subtract 9x from both sides.
-3x+2=-8
We subtract 2 from both sides.
-3x= -10
We divide both sides by -3.
x=10/3
I hope this helps!
Answer:300
Step-by-step explanation:
50+5x=?
Literally just multiply it by 50 by 5 which would be 250 plus what she already had in her account 250+50= 300
