Answer:
4/6= 2/3
Step-by-step explanation:
5/6 - 1/6 = 4/6
lowest form : 2/3
Answer:
The possible X values are the natural numbers.
RRL: X=3
AARRL: X=5
AARL: X=4
RRAL: X=4
ARL: X=3
Step-by-step explanation:
Since we are going to observe the cars and the experiment will end when one of them turns left, and X is the number of cars observed, the possible X values will be the natural numbers (1,2,3....). Clearly we can observe any number of cars before one of them turns left. We cannot observe negative numbers of cars, or zero cars (We are going to observe at least one car), or fractions of cars.
Given the outcomes below, find their associated X values:
For this part of the problem, we are going to count how many cars we observed in total and that will be the X value.
RRL: X=3
AARRL: X=5
AARL: X=4
RRAL: X=4
ARL: X=3
We know that 1 cm = 400 km
Therefore, 22 cm = x
Cross multiply:
(1)x = (400×22)
x = 8800
Solve for x by simplifying both sides of the equation, the isolating the variable. x=-8
According to the given expected value, it is found that Marcos' statement is correct.
-
The interpretation of the <em>expected value</em> is that <u>over a large number of trials, the average value will be close to the expected value</u>.
In this problem:
- The expected value is of $25.
- Hence, if many of the plans are sold, the average profit per plan will be of $25, and Marcos' statement is correct.
About Amaya's statement, among groups of 1,000 customers there can be variations, hence, she is incorrect.
