Answer:
Many solutions
Step-by-step explanation:
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>
Answer:
Step-by-step explanation:
5,9,11,(13,16),16,19,21
the mean(middle number) = (13 + 16) / 2 = 29/2 = 14.5
Q1 = (9 + 11) / 2 = 20/2 = 10
Q3 = (16 + 19) / 2 = 35/2 = 17.5
interquartile range (IQR) = Q3 - Q1 = 17.5 - 10 = 7.5 <==
Remember, mean is average. So first you add them all up, and then divide by the total number. All the dollars added up and then divided by 6 equals 59. So, working backwards, if you multiply 6 (the number of categories) by 59 you get the total of all money earned from every category. 6 times 59 equals 354. But if you add what you can see right now, it only equals 274. So the t-shirt total must be the difference between the two... 80 dollars.
