Step-by-step explanation:
Answer:
b. {-9, 3}.
Step-by-step explanation:
x^2 + 6x - 27 = 0
We need 2 numbers whose product is -27 and whose sum is + 6.
These are + 9 and - 3. So the factors are:
(x - 3)(x + 9) = 0
(x - 3) = 0 or (x + 9) = 0
x = 3 or -9.
(A) Mean best describes the amount of water in each bucket.
<h3>
What is mean?</h3>
- A dataset's mean (also known as the arithmetic mean, as opposed to the geometric mean) is the sum of all values divided by the total number of values.
- It is the most widely used measure of central tendency and is frequently referred to as the "average."
- In mathematics, particularly statistics, there are several types of means.
- Each mean is used to summarize a specific set of data, often in order to better understand the overall value (magnitude and sign) of a given data set.
- In two simple steps, we can calculate the mean or average of a data set: add up all of the values to find the sum.
- Subtract the sum from the total number of values in the data set.
Therefore, (A) mean best describes the amount of water in each bucket.

The correct question is given below:

B. range
C. outlier
D. mean absolute deviation
Using the <u>arrangements and the probability concept</u>, it is found that there is a 0.75 = 75% probability that the number formed is not divisible by 4.
- A probability is the <u>number of desired outcomes divided by the number of total outcomes</u>.
- The number of possible arrangements of n elements is given by
In this problem, there are 4 elements, hence 
.
A number is a multiple of 4 if the <u>number composed by it's last 2 digits are multiples of 4</u>.
- Hence, the possible options for the last 2 digits are: 56, 68, 76.
- For each of them, there are
options for the first 2 digits, hence, there will be 2 x 3 = 6 multiples of 4.
The other 18 numbers formed are not divisible by 4, hence:
0.75 = 75% probability that the number formed is not divisible by 4.
