Answer:
0.688 or 68.8%
Step-by-step explanation:
Percentage of high school dropouts = P(D) = 9.3% = 0.093
Percentage of high school dropouts who are white = = 6.4% = 0.064
We need to find the probability that a randomly selected dropout is white, given that he or she is 16 to 17 years old. This is conditional probability which can be expressed as: P(W | D)
Using the formula of conditional probability, we ca write:
Using the values, we get:
P( W | D) =
Therefore, the probability that a randomly selected dropout is white, given that he or she is 16 to 17 years old is 0.688 or 68.8%
Answer:
A) Tan 60° = 1.732
B) H = 12 unit
C) Area of triangle = 41.569 unit²
Step-by-step explanation:
As shown in figure, the triangle with cone angle of 60° and base value 4 unit
A) Now, Tan 60° =
Or, Tan 60° = 1.732
B) To find value of h
since TanФ =
So, Tan 60° =
=
∴() × ( = h
∴ h = 12 unit
C) Area of this triangle = × Perpendicular × Base
= × h ×
∵ Perpendicular h = 12 unit
So, Area = × 12 ×
Hence Area of triangle = 41.569 unit²
ANSWER
Answer:
The probability of a bulb lasting for between 480 and 526 hours=0.74454
Step-by-step explanation:
We are given that
Standard deviation of the lifetime,hours
Mean, hours
We have to find the probability of a bulb lasting for between 480 and 526 hours.
Hence, the probability of a bulb lasting for between 480 and 526 hours=0.74454
Answer: C
Step-by-step explanation:
You would work backwards. So it would be 1:00-2 hours so the answer would be 11:00 A.M
