Answer:
X^2
Step-by-step explanation:
First, we should divide 282 by 3.75, because this will give us how many minutes it would take to fill the hot-tub.
This yields a result of 75.2. Now, we should convert that to hours by dividing it by 60 (to represent minutes).
When we do this, we will see that it takes 1.2533... hours to fill up, or easier represented as 1.25 hours. It could also be represented as 1 hour and 15 minutes.
Answer: 0.8572.
Step-by-step explanation:
Using trigonometric identities, we can write cos 59° in terms of sin 59° as, cos(59°) = √(1 - sin²(59°)). Here, the value of sin 59° is equal to 0.8572.
Length of one piece = 3 1/5 = 3.2 inches
Total length = 20 × 3.2 = 64 inches
The sample statistic that must have changed after the correction was made is mean. Because mean is based on all the observation in the data. So changing any value in the data will impact mean.
Changing the highest salary in the data will have no impact on median because median lies at the center of data.
Changing the highest salary in the data will have no impact on mode because mode is the most frequently occurring value in the data.
Changing the highest salary in the data will have no impact on minimum because minimum is the smallest value in the data.
Hence the only statistic which will change is mean.
