Answer:
B.
Step-by-step explanation:
Domain is the x-coordinate and the range is the y-coordinate.
B. Domain: {7}
Range: {-4, -2, 1, 4, 6}
The given numbers are 13, 27, 81, 21,43, 48,23,39,45.
Square number is that number which is a perfect square means if you multiply a number by itself the number you obtained is a perfect square i.e it's square root is a natural number.
√13=not a natural number
√27=√3×√3×√3=3√3=irrational number
√81=√9×√9=9=a natural number
√21=not a natural number
√43=not a natural number
√48=4√3=not a natural number
√23=not a natural number
√39=not a natural number
√45=3√5=not a natural number
So, out of following numbers 13 27 81 21 43 48 23 39 45→81 is the only square number.
The answer would be approximately 56.52 inches squared.
You are suppose to find the lateral surface area, since the label only go around the can, excluding the top and bottom.
To find the lateral surface area, you'd need to find the circumference of the circle, and then multiply that by the height.
Since C = πd, 3.14..*3 ≈ 9.42. And 9.42*6 = 56.52. Conclusively, the approximate amount of paper needed to make the can's label would be about 56.52 inches squared.
The absolute distance of the Evelyn scores from her mean score is greater than the absolute distance of Robin scores from his mean score.
<h3>What is Mean?</h3>
Mean is simply defined as the average of the given set of numbers. The mean is considered as one of the measures of central tendencies in statistics. The mean is said to be an arithmetic mean. It is the ratio of the sum of the observation to the total number of observations.
<h3>What is the mean absolute deviation?</h3>
Mean refers to the average of the observation and deviation means the variation from the present standard.
Given
Robin’s scores: 99, 108, 102, 107, 119
Mean = 107
MAD = 5.2
Evelyn’s scores: 125, 137, 138, 145, 145
Mean = 138
MAD = 5.6
The absolute distance of the Evelyn scores from her mean score is greater than the absolute distance of Robin scores from his mean score.
More about the mean and the mean absolute deviation link is given below.
