Answer:
p = £7.00
Step-by-step explanation:
Represent the original price by p. Then 0.80p = £5.60, or p = £7.00.
If a price is discounted by 20%, the discounted price is (1 - 0.20), or 0.80, times the original price.

Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this firm use the method of completing the square
Factor out - 1 from each term
y = - (x² - 9x + 12)
To complete the square
add/subtract (half the coefficient of the x- term )² to x² - 9x
y = - (x² + 2( - 
)x + 
- + 12 )
= - ( (x - )² - )
y = - (x - )² + ← in vertex form
Hello,
(x/ay)/b =1==>bx=ay==>y=b/a*x
If y=0 then x=0
x-intercept is 0
The total population given is 5
The number of possible samples of size 2 that can be made from these 5 values are 10
The means of these 10 values will represent the mean of the sampling distribution.
Hence the given statement is correct
Answer:
1947.78 inches or 162.31 feet.
Step-by-step explanation:
the circumference of any given circle is its diameter times pi. So, if you multiply the diameter times pi and then the circumference by 10 you get the number of inches traveled, if you divide that by 12 you get the number of feet traveled.
