Integers can only be whole numbers, so she should have said that negative WHOLE numbers are integers.
Answer:
A. f(x) = 26 + 0.05x
B. f(x) = 26 * (1.5)x
c. f(x) = 2(1.05)*
D. f(x) = 26 * (0.95).*
Step-by-step explanation:
If you change the fraction to decimals that will make it easier to compare
A. There are 24 hours in a day, so we have to divide the speed by 24, so we get 166.67
b. Now, to get it in metres per minute, we have to multiply by 1000 (to convert kilometres to metres), and divide by 60 (to convert hours to minutes)
So, we get 2777.78 metres/minute
If we ask 500 individuals whether they have credit card and if we consider the probability of people having a credit card being normally distributed, then we assume that, considering 30% do not have a credit card, everyone who is within 1SD of the mean will have a credit card, while the remaining ~15% on either tail of the distribution do not.
