What specific question do you need help with?
Remark
A function is defined as 1 y value per x value. The y values can be the same for 2 x values, but the x values must have just 1 value associated with it. I am describing a vertical line test for a function. This is a function.
A 1 to 1 function means that the function obeys the horizontal line test. That means that for every x there is only 1 y value.
A
This graph is both a function and a 1 to 1 function. So the answer is A.
None of the other answers are this complete and one of them is wrong.
B
B is wrong. It is a 1 to 1 function.
C
C is wrong. The graph is a function.
D
D is wrong. No y values are duplicated.
Answer:
CORRECT OPTION is (C) The flight will be late on one of the three days.
Step-by-step explanation:
The 7am flight from Dallas to Chicago is on time 75% of the time.
A spinner with four sections was created by Fran to simulate this scenario.
Since the 4 sections were equal, it means each section was 25% of the spinner.
3 sections were shaded. That implies 25 × 3 = 75% of the spinner was shaded area.
This coincides with the 75% probability that the flight is on time on a given day.
In other words, if the spinner's pointer lands on shaded area, the flight will be on time. If the pointer lands on an unshaded portion, the flight will be late.
Now Fran spun the spinner 3 times so she has 3 outcomes. The outcomes are:
- Shaded - Shaded - Unshaded
CORRECT OPTION is (C) The flight will be late on one of the three days.
To begin you have to find a common denominator between the two fractions. In this case that number is 8 because 4 is a factor of 8.
2/4 * 2 is basically 2*2 over 4*2 = 4/8
From there simply subtract the numerators
5/8 - 4/8 = 1/8
So 1/8 will your final answer.
A. The multiplier is (1 +.055/12)^12 ≈ 1.0564079
b. The multiplier is (1 +.054/365)^365 ≈ 1.0554804
c. The multiplier is e^.045 ≈ 1.0460279
The rate 5.5% compounded monthly is the better choice.
