A) the median is the middle measurement. Their ages could be 13, 14 and 15.
B) 2 students must be younger than 13
C) Like I said, the median is the middle measurement. If you have a list of numbers, you have to order them and take the middle number.
:) Have a nice day and maybe consider grading this answer brainliest? <3
Answer:

Step-by-step explanation:
Answer:
$19.07
Step-by-step explanation:
First off we need to find the discounted price of the jeans that Jessica bought.
We find the discount by multiplying the original price by 25% or 0.25
Discount Price = 23.98 x 0.25
Discount Price = 5.99
Now we subtract the discount from the original price.
Discounted Price = 23.98 -5.99
Discounted Price = 17.99
Now that we have the discounted price, we then compute for the sales tax.
Sales Tax = 17.99 x 0.06
Sales Tax = 1.08
Then we add the sales tax to the discounted price.
Total Price = 17.99 + 1.08
Total Price = $19.07
Jessica spent $19.07 on the jeans.
Part (a)
P(A) = 0.5
P(B) = 0.4
P(B/A) = 0.6
P(A and B) = P(A)*P(B/A)
P(A and B) = 0.5*0.6
P(A and B) = 0.3
<h3>Answer: 0.3</h3>
==========================================
Part (b)
We'll use the result from part (a)
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.5 + 0.4 - 0.3
P(A or B) = 0.6
<h3>Answer: 0.6</h3>
===========================================
Part (c)
A and B are not independent since P(B) does not equal P(B/A). The fact that event A happens changes the probability P(B). Recall that P(B/A) means "probability P(B) based on event A already happened". A and B are independent if P(B) = P(B/A).
Events A and B are not mutually exclusive since P(A or B) is not zero.
<h3>Answer: Neither</h3>
C.
