I know it’s either a or b so I would choose A but it’s up to you
The mean is 85.2
Explanation:
Add all the numbers together
98+78+84+75+91=426
Divide the sum by the amount of numbers you added together
426/5= 85.2
375.5x2, 375.5/4 = 93.875, so the answer is 844.875
Since
7 * 8 = 56
a good place to start could be
70 * 80 = 5,600
Then
72 * 80 = (70 + 2) * 80 = (70 * 80) + (2 * 80)
= 5,600 + 160 = 5,760
This number is larger than 5,590, so let's pick another factor smaller than 80 by subtracting away as many 72s as we need:
5,760 - 72 = 5,688 = 72 * 79
5,688 - 72 = 5,616 = 72 * 78
5,616 - 72 = 5,544 = 72 * 77
So the quotient is 77, and we have
5,590 = (72 * 77) + 46
Since there are 180 yellow beads already, you have to double that number, which gives you 360 yellow beads. Now you need to add all the beads together since the question specifically asks h<span>ow many packets she will make if she fills each packet with 60 beads, meaning all the beads. Adding all of the beads together gets you 895 beads. Divide this number by 60, which gets you 14.916 (This number has a repeating decimal, 6). Since the number is a decimal, we can only say that she will make 14 packets.</span>
