Answer:
25%
Step-by-step explanation:
There's a total of 5+8+7 = 20 marbles.
The chance of picking a blue marble is 
25%, as there's 5 blue marbles and a total of 20.
To get that number in the problem, you need to translate first the word problem into mathematical expression.
We will let x as the number.
six more than the product of a number and -2 is greater than 10 can be written as (-2x) + 6 > 10
We will now solve for x to get the number.
(-2x) + 6 > 10
Add -6 to both sides of the equation
-2x + 6 - 6 > 10 - 6
-2x > 4
Divide both sides of the equation with -2
Take note that if we divide a negative number in inequality, the inequality symbol will be change from greater than to less or from less than to greater than.
-2x / -2< 4 / -2
x < -2
Therefore, the number that we are looking for is less than -2.
Plug in what ever value is the function of g for x and solve:
g(3) = |3-3| = |0| = 0
g(-3) = |(-3)-3| = |(-6)| = 6

Answer:
Science students
When you find the average both plots using median, mean, or interquartile range, you will find that the score for the science students will always be greater than the score of the mathematics students. This is because none of the mathematics students scored higher than the science students, so the mean will always be greater.
MATHEMATICS :
Plot interval = 30 to 50
MEAN :
(34*2) + (40*2) + (32*1) + (33*1) + (35*1) + (37*1) + (39*1) = 324
Sample size, n = (2 + 2 + 1 + 1 + 1 + 1 + 1) = 9
Mean = 324 / 9 = 36
BOTTOM :
SCIENCE :
MEAN : (43*2)+(46*2)+(49*2)+(41*1)+(42*1)+(47*1) =
406
SAMPLE SIZE = (2 + 2 + 2 + 1 +1 +1) = 9
406 / 9 = 45.111
