Answer:
(8,-2)
Explanation:
you reflect it over the x-axis
95÷100of the time
if he ran 20 races rhus month
95÷100×20 =19
Notice that 56° = 45° + 11°. Then
tan(56°) = sin(56°) / cos(56°)
… = sin(45° + 11°) / cos(45° + 11°)
… = (sin(45°) cos(11°) + cos(45°) sin(11°)) / (cos(45°) cos(11°) - sin(45°) sin(11°))
Recall that sin(45°) = cos(45°) = 1/√2, so we can cancel each term involving 45° :
tan(56°) = (cos(11°) + sin(11°)) / (cos(11°) - sin(11°))
Answer:
It is not ''significant''
Step-by-step explanation:
Let's call the event
A : ''Answer a question correctly if a random guess is made''
Now we calculate the probability for the event A
In the exercise A occurs in only one way and the total cases are the number of possible answers
An event B is ''significant'' if
⇒A it is not a ''significant'' event
In an hour the distance will be 27+3=30 miles
27*x+3*x=41
30*x= 41
x= 41/30 hours
x= 1,3(6) hours
