Firstly you know that 7-3 is 4 so that is your whole number. next fro the fractions you have to create a common denominator.In this case both denominators can be. so 1 times 2 is 2 and 4 times 2 is 8.so 7/8 minus 2/8 is 5/8. your answer will be 4 and 5/8
Answer: 11/243
Step-by-step explanation:
Each question has 3 options: 2 incorrect and 1 correct
Probability P(correct guessing) = 1/3
P(wrong guessing) = 2/3
Probability P(4 answers correct) = 5C4 × (1/3)^4 ×(2/3)^1
Probability P(5 answers guessed correctly) =5C5 ×( 1/3)5
Therefore Probability P(4 or more answers correct) = P(4) + P(5) = (10/3^5) +( 1/3^5)
P(4 or more correct answers) = 11/243
Answer:
The installations at the Maumee branch would you expect to take more than 30 minutes is 10.
Step-by-step explanation:
Consider the provided information.
Let x is the installations at the Maumee branch take more than 30 minutes.
The work standards department at corporate headquarters recently conducted a study and found that 20% of the mufflers were not installed in 30 minutes or less.
Therefore, π=0.20
The Maumee branch installed 50 mufflers last month.
Thus, n=50
Mean of the distribution: μ=nπ
Substitute the respective values in the above formula.
μ=(50)(0.20)
μ=10
Hence, the installations at the Maumee branch would you expect to take more than 30 minutes is 10.
Answer:
The formula for volume is l x w x h.
Step-by-step explanation
To find the missing link, we do the equation backwards.
l x 2.5 x 5 = 75
If we divide 75 by 5 then by 2.5, we get 6 which becomes our length.
To check, do 5 x 2.5 x 6 which should equal 75
6 is your length
