The answer is 1A definitely
Answer:
It's like solving a quadratic, but in reverse, and in this case you'll arrive at x2+x−12=0
Explanation:
We're going to go "backwards" with this problem - normally we're asked to take a quadratic equation and find the roots. So we'll do what we normally do, but in reverse:
Let's start with the roots:
x=3, x=−4
So let's move the constants over with the x terms to have equations equal to 0:
x−3=0, x+4=0
Now we can set up the equation, as:
(x−3)(x+4)=0
We can now distribute out the 2 quantities:
x2+x−12=0
Answer:
9.09090909091% decrease
Step-by-step explanation:
1 - 10/11 = 1/11 = 9.09090909091%
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
