162 = never use a credit card
1223 = use credit card sometimes
2831 = use a credit card frequently
Probability that a randomly selected person uses a credit card frequently:
1223 / 162 + 1223 + 2831
1223 / 4216
As a percentage, this is about a 29 percent chance. I guess you could say it's unlikely, because the probability is only 29 percent.
The fact that the survey was taken on the internet means it's not really a reliable survey, because only those who have access to the internet would be able to take the survey, which rules out a good group of people.
To make this a bit easier we can convert the fractions to decimals, then add them up to find out how much flour they originally had. Rashan bought 3 7/10 pounds of flour, which becomes 3.7 pounds. Diego bought 2 3/4 pounds of flour, which becomes 2.75 pounds of flour. In total they both had 3.7 + 2.75 = 6.45 pounds of flour.
Now they used 4 3/5 pounds to bake some bread, which becomes 4.6 pounds. To find out how much flour they have left, we subtract the 4.6 from 6.45, which equals 1.85 pounds of flour left.
Answer:
e.29 d.1
Step-by-step explanation:
we will replace with the values we have :
- 300 that's a big number . Obviously it isn't a solution
- 50 : 30+50 = 80>60 so no
- 45: 30+45= 75 >60 so no
- 30+30 = 60 we have < not ≤ so no
- 1 yes . it's obvious
- 29 +30 = 59<60 so yes !
