Okay fire so the answer 14.6
Answer:
m=21 and n=21
Step-by-step explanation:
In order to maximize the area of the rectangle, you want the two side lengths to be as equal to each other as possible.
In this case, we get that 2m+2n=84, so m+n=42. In our case, m and n can equal each other, so that gives us the maximum area of 441
Proof that this works:
If we had other dimensions, like m=20 and n=22, the area would be 440, slightly less than 442. If m=19 and n=23, the area becomes 437, which is even further off from 441.
Answer: B. Population X will require a larger sample size
Step-by-step explanation:
- If a random variable say p has skewed distribution (whether right or left ) in a population then a bigger sample size is needed to make sure that the sampling distribution follows normal distribution.
Given : Two population distributions labeled X and Y.
Distribution X → highly skewed
Distribution Y → slightly skewed.
Since Distribution X more skewed so , we will need a larger sample size of population X as compared to Y.
Hence, the correct answer is B. Population X will require a larger sample size
We will consider the following possibilities:
Wins none, wins first only, wins second only, wins both
a) Wins none:
Chances are: 75% x 65% = 48.75%
Thus, there is a 48.75% chance that the horse will sell at $15,000
b) Wins first only:
Chances are: 25% x 65% = 16.25%
c) Wins second only:
Chances are: 75% x 35% = 26.25%
Thus, the chances of the horse selling at $60,000 are 16.25 + 26.25
= 42.5%
d) Wins both:
Chances are: 25% x 35% = 8.75%
The chances that the horse will sell at $100,000 are 8.75%
