Step-by-step explanation:
Let Y represent the profit per day, and x represent the number of bar sold per day. Hence:
Y = 0.25x - 2
a) The mean is given as:
b) The standard deviation of y is:
Answer: C. 0.8p
Step-by-step explanation:
Since Darien is discounting the prices by 20%, the new price will be 80% of the original price, or 0.8 times the original price
Answer:
n = -4
Step-by-step explanation:
You must write and solve a symbolic equation.
n - 6 = 5(n + 2), or
n - 6 = 5n + 10
Combining like terms, we get:
-16 = 4n,
and so n = -4
To add fractions, find the LCD - lowest common denominater, and then Combine. answer is 8/9. Decimal form = 0.888888..........
For LCD find where both bottom numbers equal the same so in this case you would have to multiply 3 times 3 to equal 9. Once you do that the 2 thats on top of the 3 will also have to be multiplied by 3 so it could make sense. Now you must Combine - it would be 6/9 +2/9. you only add the top numbers and leave the bottom number.(that is what its out of). Thus the answer is 8/9.

The formula for a circle is:
(x-p)^2+(y-q)^2=r^2
The radius is given (r=6), as well as the centre of the circle (-2;3).
"p" and "q" represent the coordinates of the centre of the circle.
So it would look like this -
(x-p)^2+(y-q)^2=r^2
p=x-coordinate (-2)
q=y-coordinate (3)
r=6
(x-(-2))^2+(y-(3))^2 =6^2
(x+2)^2 + (y-3)^2 = 36
***"^" means "to the power of"
Hope this helped~
