Answer:-2(2x + 5)2 i think
Step-by-step explanation:(8+4x)/4x= 4(2 + x)/4x= (2 + x)/x
Answer:
This is an inverse variation, and the constant of variation is k = 2.
Step-by-step explanation:
Direct variation is something like:
y = k*x
Where k is the constant of variation.
So as x increases also increases y.
Inverse variation is something like:
y = k/x
k is the constant of variation.
In this case, if x increases, y decreases.
Now let's look at the equation:
-10 + 15*x*y = 20
Let's isolate y in one side of the equation:
15*x*y = 20 + 10 = 30
15*x*y = 30
y = 30/(15*x) = (30/15)/x = 2/x
y = 2/x
Then we can conclude that this is an inverse variation, with a constant of variation equal to 2.
Answer:
Step-by-step explanation:
Given
Let
A = Event of being a universal donor.
So:
Solving (a): Mean and Standard deviation.
The mean is:
The standard deviation is:
Solving (b): P(x = 3)
The event is a binomial event an dthe probability is calculated as:
So, we have:
The mode is the score that occurs the most often and the median is the middle number when arranged in order.
120 inches.
This is because to find the scale factor, you have to take the square root of the area scale. This will give you 30-1 ratio. Then multiply the 4 by that number.
