There are a total of 5+8+2=15 marbles. There's a 5/15 chance of drawing a red marble in the first trial. Then, there are 4 red marbles and 14 total marbles left, so afterwards, there's a probability of 4/14 that the second marble is red. The probability overall is found by multiplying these together, so the first answer is the best.
There are 2+6+7=15 cakes. There's a 6/15 chance that the first cake selected will be a pineapple cake, and then a 2/14 chance that the second cake selected will be a strawberry cake, by the same logic as above. This is equal to 12/210. The first answer is the best option.
The value of 4 in 34,258 is 4,000 times the value of 4 in 47,163 is 40,000
40,000*4,000 is 160000000
Here're the answers!!! Good luck!!
1) a = -7 (The first picture -Left to right)
2) x = -39
3) a = -2.1 (The last picture left to right)

Answer:
It's about 6,111 kids per second.
Step-by-step explanation:
1 hour = 60 minutes
1 minute = 60 seconds
60*60=3600
1 hour = 3600
hourly rate -> 22,000,000 kids/hr
secondly rate -> 22,000,000/3600 ≈ 6,111
secondly rate -> 6,111 kids/second
