Answer:
Step-by-step explanation:
(x-3)/2 = 9
x - 3 = 18
x = 21
(y-5)/2= 6
y - 5 = 12
y = 17
(21, 17)
Using it's concept, it is found that there is a 0.8 = 80% probability that the learner is a senior or a male.
<h3>What is a probability?</h3>
A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.
In this problem, there is a total of 6 + 4 + 5 = 15 students. Of those, there are 6 seniors, and 6 male non-seniors, hence there are 12 desired outcomes, and the probability is given by:
p = 12/15 = 0.8 = 80%.

Answer: y = -1/2 x + 3
Step-by-step explanation:
x + 2y= 6 subtract x from both sides
-x -x
2y = 6 - x Divide both sides by 2
y = 3 - 1/2x or y = -1/2x + 3
The volume would be V = (side of base)^2 * (height). The height would be 3. To see this, make yourself a model if need be. Assuming that the dimensions of the "square piece of cardboard" are x by x, then the length (or the width) of a side of the square bottom would be x-3-3, or x - 6.
So: V = (x-6)^2*3 = (area of base)*(depth of box)
= 3(x-6)^2 (answer)
