Answer:
M = 5K/2G
Step-by-step explanation:
In order to solve for M, we'll need to cross-multiply. This means that we create an X looking figure. Leaving us with 5K = 2G(M). Next, in order to solve for M, we'll need to divide both sides by 2G. Therefore, M = 5K/2G.
The side length of the cube will only go up by a factor of 2.
Think about it like finding the volume of a cube in reverse:
If we multiply the left and right sides of this equation by 8:
And try to "distribute" the 8 by splitting it up into three 2's:
We can see the side length only doubles.
Answer:
Step-by-step explanation:
Let r = .25 probability of getting question right. and w = .75 prob getting it wrong.
since there are 10 questions, this will tell us what we want to know.
a) 1- doesn't get them all wrong.
1-
=1-.0563
=.9437
b) Probability of getting 6-10 answers right
=.0197
c)
This means 9 or 10 answer should be right
=.00003
d)
= 2.5 expected correct answers.
e)
Standard deviation for a binomial distribution is
=
=
=1.369
