Answer:
20%
Step-by-step explanation:
14/70x100=20%
He was there for 3 hours cause 3 x 35 = 105 but 105 + 55 = 160
Consider such events:
A - slip with number 3 is chosen;
B - the sum of numbers is 4.
You have to count
Use formula for conditional probability:
1. The event consists in selecting two slips, first is 3 and second should be 1, because the sum is 4. The number of favorable outcomes is exactly 1 and the number of all possible outcomes is 5·4=20 (you have 5 ways to select 1st slip and 4 ways to select 2nd slip). Then the probability of event is
2. The event consists in selecting two slips with the sum 4. The number of favorable outcomes is exactly 2 (1st slip 3 and 2nd slip 1 or 1st slip 1 and 2nd slip 3) and the number of all possible outcomes is 5·4=20 (you have 5 ways to select 1st slip and 4 ways to select 2nd slip). Then the probability of event is
3. Then
Answer:
Answer:
sin(T)
cos(C)
Step-by-step explanation:
sine goes up or down for angles in the circle.
cosine goes left or right for angles in the circle.
consider a circle with is center at T, and it goes through C (so, the radius is 25 = TC).
then 7 = sin(T)×25
24 = cos(T)×25
so, sin(T) = 7/25
then, sin(T) = cos(90-T)
and the angle at C = 90-T.
therefore, cos(C)=sin(T)=7/25
tan(x) = sin(x)/cos(x)
and that would lead here always to a 7/24 or 24/7 ratio.
so, no tan function is right.
