The simplified expression of your question is

Answer:
about 465 students do not prefer non-fiction
Step-by-step explanation:
first I labeled each section on the pie the
the blue area looks like the smallest so that's most likely 60 students
then orange is 75 students
dark blue is the biggest so its 180 students
gray and yellow are the last ones left and gray is bigger than yellow so gray is 150
the number of students that prefer non-fiction is 100 so you add all the other number to get how many students don't prefer non-fiction=465
I hope this helps and makes sense ;D
No solutions. Since when you solve for the variable in this case it would be x. x will equal 0. when you solve for variables. If the final answer is a variable that equals zero then there is no solution.
The midline of the sine function is 0. The +3 added to the sine function moves the midline of f(x) to f(x) = 3.

You may be expected to write the equation as y = 3.
Answer: the probability that the tires will fail within three years of the date of purchase is 0.12
Step-by-step explanation:
The average lifetime of a set of tires is 3.4 years. It means that μ = 3.4
Decay parameter, m = 1/3.4 = 0.294
The probability density function is
f(x) = me^-mx
Where x is a continuous random variable representing the time interval of interest(the reliability period that we are testing)
Since x = 3 years,
Therefore, the probability that the tires will fail within three years of the date of purchase is
f(3) = 0.294e^-(0.294 × 3)
f(3) = 0.294e^- 0.882
f(3) = 0.12
