725/8 = 90.625 miles per hour
Answer:
$3.21
Step-by-step explanation:
This question asks for use of technology, so you can use a hand graphing calculator or the desmos website (which I used).
I have attached the screenshot of this graph. We want the maximum value on the y axis (the axis representing profit). We can see that the highest point is at (3.571, 548.214), so this is when she makes the most money.
This means that she makes the most profit at 3.571 50 cent decreases.
3.571×0.5 is a decrease by $1.7855.
This means the best price is 5-1.7855, which is 3.2145. This can be rounded to $3.21
Answer: D 1 and 5/72 sq ft
Answer: It is 0.73 my friend. Very good work.
Step-by-step explanation:
From the distribution, it seems as though the digits at fairly even frequencies, though we can test our intuition by doing a few calculations.
The mean (or average) frequency can tell us quite a bit here, and we can calculate it by adding together all of the frequencies and then dividing by the number of frequencies (in this case, 10, since we have 10 digits)
Doing that, we find
(1 + 4 + 5 + 7 + 4 + 5 + 2 + 3 + 5 + 5)/10 = 41/10 = 4.1
When we divide the number of digits (40) by 4.1, we find it equals roughly 10, which means that, *on average*, each of the 10 digits appeared about 4 times. With this knowledge in hand, it wouldn’t be too out-there to suggest that this distribution is going to tend to even out more and more as we continue to add further decimal approximations of π
