Answer:
First in your head multiply 8 by 7. this equals 56. now multiply 8 by 9 twice since there is two 9's. now you have two 72's. Add the 2's together from both 72's. now your numbers are 70, 70, 56 and 4. Add the four to your 5 which is now 96. split 96 between the 70's. not dividing just the two numbers. now you have 79, and 76. put together your numbers and your answer is 7976.

Answer:
Third quartile (Q₃) = 46.75 minutes.
Therefore, Option (c) is the correct answer.
Step-by-step explanation:
Given: Mean (μ) = 40 minutes and S.D (σ) = 10 minutes
To find : Third quartile (Q₃) = ?
Sol: As the third quartile of normal distribution covers the 75% of the total area of the curve and first quartile covers the 25% of the total area of the curve. Then with the help of z score table, the value represented the third quartile of the normal distribution is:
Q₃ = μ + 0.675 σ
Now by substitution the value of mean and standard deviation,
Q₃ = 40 + 0.675 × (10)
Q₃ = 40 + 6.75
Q₃ = 46.75
Therefore, the third quartile (Q₃) = 46.75. So, option (c) is the correct answer.
