It has to be A because its the only one that makes sense
Step-by-step explanation:
Three hundred- fifty- five
Reason; number words refer to the alphabetical form of numbers.
Please send more context as of the "green numbers".
For the multiplication,
i 49 x 10 = 490
490 ÷ 10 = 49
ii 2.3 <span>÷ 10 = 0.23
0.23 x 10 = 2.3
iii 0.034 x 1000 = 34
34 </span><span>÷ 1000 = 0.034
iv 876 </span><span>÷ 100 = 8.76
8.76 x 100 = 876
Hope this helps :)</span>
The Arithmetic Mean and Median of the given set of data ( 2, 5, 13, 15, 19, 21 ) are 12.5 and 14 respectively.
<h3>What is Arithmetic mean?</h3>
Arithmetic mean is simply the average of a given set numbers. It is determined by dividing the sum of a given set number by their number of appearance.
Mean = Sum total of the number ÷ n
Where n is number of numbers
Median is the middle number in the data set.
Given the sets;
Mean = Sum total of the number ÷ n
Mean = (2 + 5 + 13 + 15 + 19 + 21) ÷ 6
Mean = 75 ÷ 6
Mean = 12.5
Median is the middle number in the data set.
Median = ( 13 + 15 ) ÷ 2
Median = 14
Therefore, the Arithmetic Mean and Median of the given set of data ( 2, 5, 13, 15, 19, 21 ) are 12.5 and 14 respectively.

Answer:
First, make the double negative a positive.
So, (-6/13) + (7/15)
Then multiply the numerator, 6×7=42
And denominator 13×15=195
42/195 simplify by dividing both by 3 so 14/65
