Answer:
d. 8 units
Step-by-step explanation:
If AC = 16 units then the length of CB is 8 units because DB is perpendicular bisector from the centre of circle.
Answer:
C. (-3, 2, -1)
Step-by-step explanation:
There are two types of matrices. One is REF and the other is what makes REF simpler--RREF. We use RREF to solve for REF because it makes the solution easy to find. RREF is displayed in your problem... it means that it's already solved, so the answers are already given on the right side, which is -3,2,-1. This only works with the combination provided (with the 0s and 1s). Otherwise, you'd have to solve.
Answer:
The z score for the airplane arriving 13 minutes after arrival time is 0.33
Step-by-step explanation:
Using normal distribution,
The average lateness for one of the top airline companies is 10 minutes. So our mean, u = 10
The variance, s of the lateness measure is calculated as 9.
x =13 which stands for arrival time.
Using normal distribution,
z = (x - u)/s
z = (13 - 10)/9 = 3/9 = 0.33
The z score for the airplane arriving 13 minutes after arrival time is 0.33. The probability value of the z score can be found by looking at the Normal distribution table
