Answer: y = 1.8
Step-by-step explanation:
xy = 12.6 If x is 7 but 7 in the equation for x
7y = 12.6 Divide both sides by 7
y = 1.8
Y=1 because if you remove the y’s, you see 1.4+0.09=1.49
The cumcutative property of addition
23 is the minimum because 155 does not go into evenly and you have to have enough room for everybody, and make sure not to leave anybody out. 155 divided by 7 is 22.1428571429, you have to round it up to 23 so that everybody has a seat. Hope it helps!!
Answer:
The expected value of one draw is the average value of these 10 slips of paper which is:
24 / 10 = 2.4
Step-by-step explanation:
We have a bag with 10 slips of paper in it. 8 slips of paper each has a 2 on them; 2 slips of paper each has a 4 on them.
The total value of all the slips when added together is:
= (8)(2) + (2)(4)
= 16 + 8 = 24
The expected value of one draw is the average value of these 10 slips of paper which is:
24 / 10 = 2.4 ....
