So sin in math means:
In a right angled triangle, the sine of an angle is: The length of the side opposite the angle divided by the length of the hypotenuse. The abbreviation is sin.
Con in math means:
In a right angled triangle, the cosine of an angle is: The length of the adjacent side divided by the length of the hypotenuse. The abbreviation is cos. cos(θ) = adjacent / hypotenuse.
in this case it has to be a sin. So its either A, or B.

Answer:
no
Step-by-step explanation:
Because PEMDAS is something you MUST follow no matter WHAT!!!!!!!!
Period pooo
Side length z=20
angle d=53
since they are similar triangles, angles should be the same, therefore,
d=53
if we consider the ration between the sides of the first triangle, its,
6:8:10 = 3:4:5 (when divided by the least common factor; 2)
by applying the same ratio for the second triangle, we can get,
15:20:25 (u can first divide both 15 and 25 by 5 and then multiply each term in 3:4:5 by 5)
therefore, z=20
Answer:
1. P(X=0)=0.135
2. P(T>1)=0.271
Step-by-step explanation:
1. Let X be the number of accidents in the next year. Find the distribution of X and calculate P(X=0).
The rigth distribution to describe this type of event as number of accidents per unit of time is the Poisson distribution.
In this case k=0 accidents, parameter λ=2 events/year and t=1 year:
2. Let T be the amount of time until the next accident. Find the distribution of T and calculate P(T>1).
In this case, the time between events can be best described by an exponential distribution:
In this case parameter λ=2 events/year and t=1 year:
Speed = Distance / Time
Distance = 287 miles , Time = 3 hours and 30 minutes = 3.5 hours
Speed = 287 miles / 3.5 hours
= 82 miles/hour
