Answer:
See below
Step-by-step explanation:
P stands for probability that ( what ever is in the parentheses)
Total Number of Items In Box 1: 3+5= 8
P(picking a plain pencil given you are in box 1)= 3/8
Total Number of Items in Box 2: 9+3= 12
P(picking a color pencil given you are in box 2)= 9/12= 3/4
Because he could only cover 50% of the price 25 by the coupon and 25 which he had.
The answer is true because 18 is bigger then 15
To get the mean, you add all of the numbers, and then divide the answer by the number of numbers.
15+(-6)= 9
9+12= 21
(21+x= q )⬅️ignore this for now, that's where the unknown number would have been
The mean = 5, and the number of numbers is 4, so basically, you find 5•4=20
So take the 21 from before, and if you add -1, you get 20!
So, x= ➖1⃣!!!!!!! (That's a -1)
