Answer:
0.9 = 90% probability that it arrived during the last 30 seconds of the 5-minute period.
Step-by-step explanation:
The car is equally as likely to arrive during each second of the interval, which means that the uniform distribution is used to solve this question.
A distribution is called uniform if each outcome has the same probability of happening.
The uniform distribution has two bounds, a and b, and the probability of finding a value higher than x is given by:
5-minute period
This means that
Find the probability that it arrived during the last 30 seconds of the 5-minute period.
300 - 30 = 270. So
0.9 = 90% probability that it arrived during the last 30 seconds of the 5-minute period.
Answer:
8/9
Step-by-step explanation:
In the standard form of line y = mx + b
m is the slope and b is the y-intercept
so just compare these two equations and you will see that the slope here is just 8/9
Answer:
The last one
Step-by-step explanation:
Answer:
e, f
Step-by-step explanation:
A measurement of variability is an overview of the amount of dispersion in a dataset. The measures that can describe the variation on a data set are Range, Interquartile Range, Variance, and Standard Deviation.
So ,The among the given options the e. Interquartile range f. Range
Range of dataset is the difference between the larges and smallest elements in the dataset .
The middle of the data between the upper and lower quartiles are called the inter-quartile range. That means that 50 percent of data points between Q1 and Q3 are included within the interquartile range.
Answer:
y = 2
Step-by-step explanation:
use slope formula:
(4 - y) / (3 - 10) = -2/7
4-y / -7 = -2 /7
cross-multiply:
7(4 - y) = (-7)(-2)
28 - 7y = 14
-7y = -14
y = 2
