You paint 13 1 3 of a wall in 14 1 4 hour. At that rate, how long will it take you to paint one wall?
Lady bird [3.3K]

Find the rate at which you work, that is, the # of walls painted per hour:

13 1/3 walls          40/3

------------------  = ---------- wall per hour

14 1/4 hr              57/4

Keep 40/3 as it is; invert the divisor (57/4) and then multiply the result by 40/3:

40        4        160 wall

------ * ------  = --------------- = approx. 0.94 wall in one hour, or 160/171 wall / hr

  3       57        171 hr

Mr. Clark claims that he has a coin that is weighted so that the probability of heads is 40%. To test this, his students flip th
Brrunno [24]
While I'm unsure what the word choices were, his claim is likely to be true. 

Since he claims the probability of heads is 40%, that should be what we see in an experiment.  0.38 is very close to 0.40, or 40%, so this is true.  Therefore his claim is likely to be true, and the probability of tails should be about 60%.

Calculate the average rate of change for the function f(x)=x^4+3x^3-5x^2-2, from x=-1 to x=1
PSYCHO15rus [73]

1

∫ f(x) dx = x⁵/5 + 3x⁴/4 - 5x³/3

-1

[1⁵/5 + 3⁴/4 - 5³/3] - [ -1⁵/5 -3⁴/4 +5³/3]

plug that into your calculator and that's your rate of change
