Answer:
Option B is correct.
Miguel should study for the Science quiz as he will do worse in that quiz by guessing.
Step-by-step explanation:
Miguel has to take two quizzes
1) 4 true or false questions on History with a 0.5 chance of acing the quiz
Expected number of correct questions = np
n = number of questions
p = probability of acing the test
Expected number of correct questions = 4 × 0.5 = 2
2) 3 multiple choice questions on Science with a 0.2 chance of acing the quiz.
Expected number of correct questions = 0.2 × 3 = 0.6
It is evident that guessing would yield a worse result in the Science quiz with less than 1 question expected to be correct than history, where he is still expected to get 2 questions correctly by guessing.
Hope this Helps!!!
Answer: 504.91 miles
Step-by-step explanation:
From the question, we are told that Trevon and his friends are going on a road trip that is 594 7/25 miles long and that they have 89 37/100 miles to reach their destination. To know how far that they've already traveled, we subtract 89 37/100 from 594 7/25.
= 594 7/25 - 89 37/100
Since the answer should be in decimal, we can change the fractions to decimal.
= 594 7/25 - 89 37/100
= [594 +(7/25 × 100)] - [89 + (37/100 × 100)]
= (594 + 0.28) - (89 + 0.37)
= 594.28 - 89.37
= 504.91 miles
They've already travelled 504.91 miles
