Answer:
4 sophomore girls .
Step-by-step explanation:
If a student's gender and class are to be independent when a student is selected at random, two conditions must be met:
n° boys = n° girls
n° freshmen = n° sophomore
Currently, there are 10 boys and 6 girls, thus 4 girls must join.
Currently, there are 10 freshmen and 6 sophomores, thus 4 sophomores must join.
Therefore, 4 sophomore girls must join.
rewrite the equation set = to 0.
x^2 + 5x - 8 = 0
The quadratic will not factor so you have to use the quadratic formula.
x = (-b + - sqrt(b^2 - 4ac))/2a
x = (5 + - sqrt(25 - 4* 1* -8))/2
x = (5 + - sqrt 57)/2
The x2is not the same as 2x. It is x^2. X tot he second power which makes the problem a quadratic equation. You cannot combine the terms x^2 and -5x because they so not have the same power.
Answer:
For me
Step-by-step explanation:
I think it's part to whole because you are comparing holiday celebrated to total students
Answer: If the box holds all the sugar cubes and only the sugar cubes it has a volume of 24 cubic units. the units will be the side measurement of one of the sides of the sugar cube. The smallest zero is x = -10 as its the left-most value on a number line.
Step-by-step explanation:
Answer:
1 (the answer will always be 1)
Step-by-step explanation:
Let's forget about the absolute value signs for a second and just look at what's inside
This can be rewritten as
When you have the same numerator and denominator, it will always come out to 1, so we can just say that this is saying
Now, back to the absolute value signs
This comes out to negative 1, but the absolute value signs means to always change the negative to a positive (but if it's a positive, it stays positive!)
So that means:
and 1 is your answer
