Answer: 1.6 is the answer :)
Step-by-step explanation:
12:18 is a 2:3 ratio of pink to blue
If this ratio continues for the population of the box;
the ratio has 5 parts. 100/5 = 20. Each part is 20.
2 * 20 = 40
3 * 20 = 60
P:B = 40:60
40 pink chips and 60 blue chips
Just add:
3 3/4+4 5/8=3 6/8+4 5/8= 8 3/8
then subtract:
11 1/8 - 8 3/8= 2 3/4
so she had 2 3/4 more that the other two

Can a function be concave down and positive everywhere?can be a semicircle
example, y=4+

attachment 1
Can a function be increasing and be concave down everywhere?no, concave down means increase slope then decrease slope
Can a function have two local extrema and three inflection points?inflection points are where the concavity changes
it can be at the ends, the middle and the other end
like in atachment 2, the circles are inflection points
Can a function have 4 zeros and two local extrema?
no, as you can see in attachment 3, there can be 3 zeroes at most for 2 local extrema

If he's average speed per minute is 1,448 meters per minute, and there are 60 minutes in a single hour. You would multiply 1,448 by 60 to get the answer of 86,880 meters per hour.
