Answer:
A.
Step-by-step explanation:
<u>Conditional probability</u>:-
If E and F are two events in a sample space S and P( F) ≠ 0 , then the probability of 'F' after the event 'E' has occurred, is called the conditional probability of the event of F given E and is denoted by
P(E/F) =
"Police report that 78% of drivers are given a breath test
36% a blood test and 22% both tests
let 'B' be the event of blood test and 'Br' be the event of breath test
0.9874 the greatest non zero place is 9 but the nearest digit is 8 when you round it off to 0.9 the answer becomes 1.0
0.9874~1.0
The triangle is merely rotated. No other changes have been done to it whatsoever. Therefore, the measure of the angle should still be the same. Since angle KLM is equal to 30 degrees, then the measure of angle BCD should also be equal to 30 degrees.
Answer: <span>m∠BCD=30°</span>
Answer:
Xavier will not be able to qualify because the speed required for him to qualify is greater than the speed at which he runs
Step-by-step explanation:
Here, we want to know if Xavier will be able to qualify or not
His constant speed is 5/3 m/s
Now to win , he needs a speed of 100 m/55 sec = 20/11 m/s
So now, we need to know the bigger fraction between the two
Mathematically, that will be
5/3 - 20/11 = (55-60)/11 = -5/11
As we can see, the required speed is greater than what he can run
So this means that he will not be able to qualify
