Answer:
5/6 chance
Step-by-step explanation:
If we were to look as 1 hour as a 2 halves, and we have 3 hours, from 9 to 12, we can do 2 halves x 3 hours to equal 6, thus have a probablity out of 6. If you were to be there without leaving, there would be 6/6 times, meaning you wouldn't miss him, but since there is a half hour you are gone, the fraction then becomes 5/6 instead of 6/6. In this case, there is a 5/6 chance that you will be home the same time the repair person comes.
The equation for the determination of the z-score is shown below.
z-score = (x - μ) / σ
where x is the value in which we need to determine the z-score, μ is the mean or the average, and σ is the standard deviation.
Substituting the known values,
z-score = (1,030.00 - 1,200) / 100 = -1.7
Therefore, the z-score of 1,030 is -1.7.
Answer:
Option B. Amplitude =3 midline is y =2.
Step-by-step explanation:
In the graph attached we have to find the amplitude and midline of the periodic function.
Amplitude of the periodic function = (Distance between two extreme points on y asxis)/2
= (5-(-1))/2 = (5+1)/2 =6/2 =3.
Since amplitude of this function is 3 and by definition amplitude of any periodic function is the distance between the midline and the extreme point of wave on one side.
Therefore midline of the wave function is y=2 from which measurement of the amplitude is 3.
Answer:
19.8
Step-by-step explanation:
You have to first put the numbers into ascending order:
8.4, 9.3, 11.4, 18.5, 19.6, 20, 26.1, 32.3, 44.1, 46.41.
Because there is an even amount of numbers, you end up with 19.6 and 20.
The in between of 19.6 and 20 is 19.8.
(You can work this out by adding the two numbers together and then dividing by two if you have to.)
