Answer:
Step-by-step explanation:
tan Ф = opposite side divided by the adjacent side
tan Ф = opp/adj in your problem Ф is x
tan x = 4/9
x = arctan (4/9) on your calculator arctan is might look like inverse tan
or you might have to use the 2nd (second) button and then tan
x = inverse tan (0.44444 repeating) try it on your own calculator
= 23.962488974578183 rounds up to 24.0
= 24.0

Answer:
Step-by-step explanation:
a. #We notice this is a Poisson probability function expressed as:
x-number of occurrences in a given interval.
-mean occurrences of the event
-The mean is calculated as:
#the probability of no accidents in a 15-minute period is :
Hence, the probability of no accident in a 15-min period is
b. The the probability of at least one accident in a 15-minute period. is calculated as:
Hence, the probability of at least one accident in a 15-minute period is
c. The probability of four or more accidents in a 15-minute period is calculated as:
Hence,the probability of four or more accidents in a 15-minute period. is 0.9997
Answer:
18c-30d+36
Step-by-step explanation:
The slope is the factor a in front of the x after rewriting in y = ax + b form.
Your equation becomes:
3y = 4x - 1 - 5
3y = 4x - 6
y = 4/3 x - 2
now you can see the slope is 4/3
