Answer:
Quinn can expect to pick blue 40 times
Step-by-step explanation:
the probability of picking blue is stated as 2/10 which can be reduced to 1/5
multiply the number of times they pick a marble ( shown as 200) by the probability of picking a blue one ( 1/5)
200 x 1/5 = 200 / 5 = 40
Quinn can expect to pick blue 40 times
The number of chairs that still need to be set up are 150.
You add up 1+1+1+1+2 and you get 6. You then subtract 6 by 200 and your answer is -194

<h2>
Why?</h2>
From the statement we know that the cheetah can reach a speed of 70 mph, but it can be maintained for no more than 1,640 feet.
The expression "no more than" means that at least it can be reached but never exceeded, it involves that the distance can be less or equal than 1,640 feet but never more than that.
So, the correct option is:
B. 
Have a nice day!
Less than. -20 is not the same as positive 20
