Answer:
35 red marbles
Step-by-step explanation:
So we can put the different color marbles in a ratio. So 7:2:11. If we add all of those up we get 20. We do 100/20 to get 5. Each number in the ratio is equivalent to 5 marbles. Then we do 7*5 to get 35. We can check our work by doing, (7*5) + (2*5) + (11*5) = 100. And it does equal 100 so the answer is correct.
15.6 in 13 minutes? are you asking how it got to 15.6 in 13 minutes?
15u + 11u - 9d - 19d = -2d
It went up 26, down 28, a net change of down 2.
Answer:
first blank: mean
second blank: greater than
third blank: increased
fourth blank: greater than
Step-by-step explanation:
I can't see the options in each blank, even though I completed them with reasonable options.
The MAD of a set of data is the average distance between each data value and the mean. 400 is further than the mean than the MAD. This, increases the variability of the originally data set. As a consequence, the inclusion of 400 will result in a greater MAD
