X² + c is actually a quadratic function.
And x² + c = 0, it usually has two zeros which are solutions.
But for when c = 0,
x² + c = 0
x² + 0 = 0
x² = 0
Taking the square root of both sides.
x = 0. Here it only has one zero.
So the function x² + c, only has one root for c = 0.
Answer:
6
Step-by-step explanation:
30-6=24
(6 people walked which means they are not included in the people fitting on the busses)
24/4=6
(from there you need to divide by 4 to tell how many were on each bus.)
First, determine the weight of 330 cans with the given conditions,
(330 cans) x (4 lbs / 100 cans) = 13.2 lbs
Then, the price is determined by multiplying this weight to the price that the recycling center is paying,
(13.2 lbs) x (25 cents / lb) = 330 cents = $3.3
Thus, Robert will be paid $3.3.
The correct answer is 25%
<h3>
What is Relative Frequency?</h3>
- The number of times an event occurs divided by the total number of events occurring in a given data.
<h3>How to solve the problem?</h3>
- This problem can be solved by following steps.
- The data of color and frequency is given in table.
- We need find the relative frequency for Purple
First calculate the the total number of frequency
18+20+10+16
= 64
The total number of frequency is 64
Hence the relative frequency of purple is 16/64
Therefore , relative frequency of purple is 1/4 = 0.25
Therefore 25% of purple candies are there
