I think 3.323 units would be the correct answer. Are you asking what the length of a single side is?
Answer: So the number of outcomes with exactly 4 tails is 720/2/24 = 15. Finally we can now calculate the probability of getting exactly 4 tails in 6 coin tosses as 15/64 = 0.234 to 3 decimal places.
D'(p) = -8p + 160
<span>-8p + 160 = 0 </span>
<span>-8p = -160 </span>
<span>p = 20 </span>
<span>~~~ </span>
<span>B) Number of drills sold when p = 20 is </span>
<span>D(20) = [ -4(20)^2 + 160(20) - 270 ] = 1,130 drills </span>
I think this is right, i tried.
The correct answer is a.
Inside the function it says x+2, and a +2 means it is to the left (direction is opposite of the sign)
The 3 on the outside of the function shows how the steepness, or slope will change. The first is correct because slope is rise over run, and if you go from one point to another, you'll see that it is up 3 and over 1, or 3/1, or 3.
