Answer:
Step-by-step explanation:
Approximately 95% of the population has IQ scores between 70 and 130. Approximately 99.7% of the population has IQ scores between 55 and 145. Only approximately 0.3% of the population has IQ scores outside of this interval (less than 55 or higher than 145).
Answer: A.Median; because the data is not symmetric and there are outliers
Step-by-step explanation:
From the given dot plot , we can see that the data plot is skewed not symmetric .
Aldo there are outliers at 9 since most of the dots are between 0 to 4.
We know that the median provides better description of the center of the data then mean when the data is skewed.
Therefore , the median is a better center for this data because the data is not symmetric and there are outliers.
Answer:
There is no option in the question given.
However, In logic and probability theory, two events are mutually exclusive or disjoint if they cannot both occur at the same time. A clear example is the set of outcomes of a single coin toss, which can result in either heads or tails, but not both.
You should draw a diagram
And it should make a triangle and solve using SOH-CAH-TOA (sin cos tan) relative to your angle of 69 degrees
4.25(15)+4.25(1.5)(7)+0.21(1345)=
63.75+44.625+282.45=$390.825
=$390.83
