<u>35.12 miles </u><u>is the total number of minutes that it took krissy to run these three miles.</u>
What is a simple definition of time?
The measured or measurable period during which an action, process, or condition exists or continues : duration. b : a nonspatial continuum that is measured in terms of events which succeed one another from past through present to future.
Krissy ran three miles one morning she ran the first mile in time 1 = 11.74
Krissy ran three miles one morning she ran the first mile in time 2 = 11.26
Krissy ran three miles one morning she ran the first mile in time 3 = 12.12
To get total time , we have to add all the time 1,2,3
Total time = Time1 + Time2 + Time3
= 11.74 + 11.26 + 12.12
Total Time = 35.12 <u>miles</u>

Answer:
a.) 0.1685
b.) 0.7922
Step-by-step explanation:
This question is solved by the probability distribution formula for selection which uses the combination formula to derive the answer.
If 7 out of 12 cases Of refrigerators are said to have compressor problem, then the success rate to be used in the probability distribution formula = p = 7/12 = 0.583
Probability of failure = q = 0.417
When choosing r samples from a possible n sample, then probability distribution formula is denoted by :
P(X=r) = nCr × p^n × q^n-r
a.) From possible 6 samples, if P(X=5)
P(X=5) = 6C5 × 0.583^5 × 0.417¹
P(X=5) = 0.1685
b.) P(X≤4) =1 -P(X>4) = 1 - P(X=5) - P(X=6)
P(X=5) as calculated earlier = 0.1685
P(X=6) = 6C6 × 0.583^6 × 0.417^0
P(X=6) = 0.0393.
Hence, P(X≤4) = 1- 0.1685 - 0.0393
P(X≤4) = 0.7922
The mean could be used to describe a data set by itself, while interquartile range would almost never be used to describe a data set by itself.
<h3>What is Descriptive statistics?</h3>
These are operations which are used to summarize certain characteristics a set of data has.
Mean and range deals with the full set of data while interquartile range measures just the middle half of the data and is denoted as option A.
