Step-by-step explanation:
A solution to a system of equations is the point where the 2 lines meet.
I think it's B and D because both of them will give you the same answer which is 2.71 but turn it into fraction.
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.
Answer:
Step-by-step explanation:
perimeter = sum of the sides = (3y+5) + (y-4) + (6y) = 10y + 1
Answer:
The answer is C. A triangle has a total angle of 180°, therefore C. is more than 180°
