It’s 20% because 10/10 would be 100% and 1/10 would be 10%
Answer:
<em>x ∈ ( - ∞ , - 8 ) ∪ ( - 8 , 0 ) ∪ ( 0 , 8 ) ∪ ( 8 , ∞ ) </em>
Step-by-step explanation:
x³ - 64x = x( x² - 64 ) ≠ 0 ⇒ x ≠ 0 and x ≠ ± 8
<em>x ∈ ( - ∞ , - 8 ) ∪ ( - 8 , 0 ) ∪ ( 0 , 8 ) ∪ ( 8 , ∞ )</em>
A is true, b is true, but c d aren’t and e is
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
