Opposite number or additive inverse of any number (n) is a number which, if added to n, results in 0, the identity element of addition. You can say that the opposite number of a number, is the negative version of the positive number. This is what the opposite of 4 is or the opposite of -4
13, 17, 15, 18, 21, 13, 20;(the add 3.7 has no place in this data set .Ignore it)
1) arrange the data from smaller to greater: 13 13 15 17 18 20 21
2) mean: Add up all data & divide by the number of data
that is 7==> (117/)/7 so the mean = 16.71
3) Median is the central value of the data point that is in the middle of the sequence, so the median is 18
4) Mode the number that is most repeated & it's 13 (repeated twice)
5) The range is the difference between the largest & the smallest
Range = 21-13 ==> Range = 8
There is a problem in answers you have written: Either you mistyped or omitted something or the answer are false. With the data you gave me, my methodology is 100% right
Step-by-step explanation:
73% to make a percent into a decimal move it two places to the left
Answer: 0.73
Answer:
Yes, Jean is correct
Step-by-step explanation:
Given
Required
Determine the value of the result
<em>When a positive integer is multiplied by a fraction, the result is always less than the integer</em>
<em>Solving further</em>
<em>The result of the expression shows that the resulting value is less than 73.</em>
<em>Hence, Jean is correct</em>
