Answer: 28
Step-by-step explanation:
Number of cases= 33
Percentage increase= 14.6%
To get the number of cases the previous year, we find the increase from last year and subtract.
= 14.6% of 33
= 14.6/100 × 33
= 4.82
So, the increase was 4.82
To get last year number, we subtract 4.82 from 33.
33 - 4.82 = 28.18 which is approximately 28.

The answer is 15.
S - small jar
M - medium jar
L - large jar
In all Amanda has 22 jars: S + M + L = 22
She has three time as many small jars as large: S = 3L
She has three fewer mediums than large: M = L -3
Now, we can use the method of substitution:
S = 3L
M = L - 3
_______________
S + M + L = 22
3L + L - 3 + L = 22
3L + L + L = 22 + 3
5L = 25
L = 25 ÷ 5 = 5
Since S = 3L, then:
S = 3 · 5 = 15
Amanda has 15 small jars.
i would say independent since the problem doesn't state any relation between disease X and disease Y. Also I beleive if it were dependent the probability of getting both wouldn't be .494 (which is .65 *.76). It would have to be probability of event A and event B, and then divided by probability of just B
