1000 miles per month.
12 months in a year.
1000 × 12 = 12000 miles per year
Oil change every 4000 miles.
12000 ÷ 4000 = 3
Therefore 3 oil changes per year.
Answer:
Second option: (-2,-3) and (1,0)
Step-by-step explanation:
Given the system of equations 
, you can rewrite them in this form:
Simplify:
Factor the quadratic equation. Choose two number whose sum be 1 and whose product be -2. These are: 2 and -1, then:
Substitute each value of "x" into any of the original equation to find the values of "y":
Then, the solutions are:
(-2,-3) and (1,0)
Answer:
Unpredictable
Step-by-step explanation:
Cuz if u look at it it is also random and u cant predict a random thing, so its quite simply unpredictable
Considering a discrete distribution, it is found that the expected number of new employees to be hired by the airline is of 446.16.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
In this problem, considering the situation described in the text, the distribution is given by:
Hence, the expected value is given by:
E(X) = 0.37(867) + 0.63(199) = 446.16.
