Answer:
(x - 4)² + (y + 6)² = 5²
Step-by-step explanation:
rearrange the general equation as follows
collect the terms in x and y together and place the constant on the right side
x² - 8x + y² + 12y = - 27
add (half the coefficient of the x/y term)² to both sides
x² + 2(- 4)x + y² + 2(6)y = - 27
(x - 4)² + 16 + (y + 6)² + 36 = - 27 + 16 + 36
(x - 4)² + (y + 6)² = 25
(x - 4)² + (y + 6)² = 5² ← in standard form
P(compact car) = number of compact cars / total number of cars = 4/25 = 16%
Answer: 0.28
Step-by-step explanation:
Let´s name the proportion of orders
- with no optional features: "N"
- with one optional feature: "O"
- and the proportion of orders with more than one optional feature: "M"
<em>The sum of all of these proportions is equal to the total quantity of orders.</em>
Therefore,
N + O + M = 1
Then, substracting N and O on each side of that equation,
the proportion of orders with more than one optional feature (M) is:
M = 1 - N - O
M = 1 - 0.38 - 0,34
M = 0.28
