100 multiplied by two equal 200.
The mean is 12.1 and the median is 9.
To find the mean you add together all the values (8,8,9,9,9,9,9,10,10,40) and divide the sum (121) by the number of values there are (10). Thus making the mean 12.1.
To find the median, you sort the values numerically, and find the middle-most number. When doing so, you find that there are 2 numbers in the middle of this value set (since there are an even number of values). Since the 2 left-over values are 9, the median is 9.
I hope this helps!
Wouldnt it be 21 idk dont pay attention to me lol
Answer: 30 + 45 = 15(2 + 3)
Step-by-step explanation:
The greatest common factor for 30 and 45 will be gotten as follows:
Factor of 30 = 2 × 3 × 5
Factor of 45 = 3 × 3 × 5.
GCF = 3× 5 = 15
Therefore, the equation that shows how to rewrite the sum of 30 and 45 using their greatest common factor will be:
30 + 45 = 15(2 + 3)
