Let x represent the time it takes from when someone enters the line for a roller coaster until they exit on the other side. consider the probability model defined by the cumulative distribution function given below.
0 x < 3
f(x) = (x-3)/1.13 3 < x < 4.13
1 x > 4.13
what is e(x)? give your answer to three decimal places.
what is the value c such that p(x < c) = 0.75? give your answer to four decimal places.
what is the probability that x falls within 0.28 minutes of its mean? give your answer to four decimal places.

22.83 repeating

step-by-step explanation:

137 ÷ 6 is 22.8333333 therefore we understand that 3 is repeating.

think about the doctor who treated the major and the speaker in the short story "in another country." put yourself in the shoes of the doctor, and based on what you read in the story, write what you think his thoughts about the major and the speaker would be. use the following vocabulary in your response and change the form of these words as needed: detached resign withered

hmu if ur willing to do a algebra a online class i’ll pay 600 hmu on the gram profitpreme

step-by-step explanation:

to determine whether a given function is even, we simply substitute x with -x in the expression. if the result after simplification is identical to the original equation, then the function is said to be even other wise odd.

f(-x) = (-x)^2 - (-x) + 8

      = x^2 + x +8

the resulting function is not identical to the original one;

f(-x) ≠ f(x)

therefore, f(x) is not an even function
