Answer:
C/8
Step-by-step explanation:
Because the range is the biggest number subtracted by the lowest number and in our data sat 7,15,and 12 15 is the biggest number and 7 is the smallest so what's 15-7?
8 so C
Have a great day.
Answer:
the third angle= 180-x-(4x+15)
Step-by-step explanation:
if we subtract the two other angles the result will be the measure of the last one
Answer:
The answer is A, -4.
Step-by-step explanation:
For solving the parenthesis, 2/3 + 2 = 8/3, Since 2 is equivalent to 6/3.
-4 + 8/3 = -4/3. n = 1/3, so the equation would be -4/3 divided by 1/3. that would equal to -4.
Hello from MrBillDoesMath!
Answer: 500
Discussion:
The idea is to represent p(x) with a squared component...
3 + 4x - 4x^2 =
3 - ( 4x^2 - 4x) =
Add and subtract 1:
(3+1) - (4x^2-4x +1) =
4 - (2x-1)^2
To maximize profit we need to minimize the term (2x-1)^2 as it is always positive (or zero) and subtracts from the number 4. The minimum of (2x -1)^2 occurs when 2x -1 = 0 or x = 1/2. Since x is the number of speakers in thousands, (1/2)x = 500 speakers.
Note: this problem can be more easily addressed in a Calculus course by taking the first derivative of p(x), setting it to zero, and solving for x (which yields x = 1/2 too)
Thank you,
MrB
