Answer:
A. He has $22 because he spends $2 on snacks each day.
B. He spends $2 a day, in the table we can see it decreases by $2 each day, so he spends $2 every day.
C. Yes because the cost evenly decreases by $2, therefore it is a linear relationship.
D. ?
E. X ÷ Y = Z
X being the money, $22
Y being the days, 6
Z being the leftover money, $8
Problem 1
Answer: Closer to 1
Explanation:
There are 20 gumballs total. Half of this is 20/2 = 10 gumballs. If there's more than 10 of one color, then the probability of getting that color is closer to 1, than it is to 0. Here we have 12 pink which is greater than 10, so that's why the answer is closer to 1.
================================================
Problem 2
Answer: Closer to 0
Explanation:
The amount of green (3) is less than 10, so that's why the probability is closer to 0 than it is to 1. We can see that 3/20 = 0.15 is less than 0.50
================================================
Problem 3
Answer: Closer to 0
Explanation:
We have a similar situation compared to problem 2. This time we have 5/20 = 0.25 which is less than 0.50
================================================
Problem 4
Answer: 48% chance; fairly likely
Explanation:
We have 12 green out of 25 total, so the probability of choosing green is 12/25 = 0.48 = 48%. While this probability is not over 50%, I still say it's fairly likely considering the other colors lead to smaller probabilities. For instance, purple has a chance of 6/25 = 0.24 = 24% and orange has a probability of 2/25 = 0.04 = 4%, both of which are smaller than 48%
Answer: 20,000
Step-by-step explanation:
We can estimate the product of 5 and 4,257 by multiplying 5 by 4,000
5 * 4,000 = 20,000
The product of 5 and 4,257 is about 20,000
The real answer (not an estimate)
21,285
That is around 20,000 so we are correct
