Answer:
2.75 miles jogged on the fourth day
Step-by-step explanation:
Justin jogged 2 miles on the first day.
On the second day he jogged 75% of 2 miles. To find 75% of 2 miles we need to divide by 100 and multiply by 75.
2 / 100 = 0.02 x 75 = 1.5 miles jogged on the second day. (3.5 miles jogged in total so far)
On the third day he jogged 1.5 miles more than the last day:
1.5 + 1.5 = 3 (6.5 miles jogged so far)
9.25 total miles were jogged, meaning that we will need to subtract 6.5 from 9.25 to get the answer:
9.25 - 6.5 = 2.75 miles jogged on the fourth day

= 4.47 + 4.47 + 6.32 + 6.32
= 21.58 units

Answer: The answer is multiple choice questions.
Step-by-step explanation: Given that Mrs. Myles wants to know if her students prefer multiple choice or short answer tests.
According to me, Mrs. Myles should ask her students multiple choice questions, because in these type of questions, we get information not only about the correct option but it also reminds us what the incorrect options are related to.
So, these questions are better than short answers which are related to only one topic rather than three or four in the queue for multiple choice questions.
Thus, Mrs. Myles should ask her students multiple choice questions.
