4!= 4*3*2*1
Therefore,
2x0+x!= 0+x! = 0+4!
4*3*2*1 = 24 (#1)
Answer:
Option C) a positive correlation.
Step-by-step explanation:
We are given the following in the question:
" People who tend to score low on one variable tend to score low on another variable."
Correlation:
- Correlation is a technique that help us to find or define a linear relationship between two variables.
- It is a measure of linear relationship between two quantities.
- A positive correlation means that an increase in one quantity leads to an increase in another quantity or decrease in one quantity leads to decrease in another quantity.
- A negative correlation means with increase in one quantity the other quantity decreases.
- +1 tells about a a perfect positive linear relationship and −1 indicates a perfect negative linear relationship.
Since, for the given case with decrease in one variable other also decreases, thus, it is an example of positive correlation. Thus, the correlation coefficient cannot be less than or equal to zero.
Thus, the correct answer is
Option C) a positive correlation.
Given a variable, x, the compound ineaquality representing the range from a to b inclusive of the variable is given by
where a is the least value and b is the greatest value.
Thus, given a variable f, representing the frequencies for the three octaves of a <span>typical acoustic guitar.
</span>
Where the range of the frequencies is between 82.4 Hertz and 659.2 Hertz inclusive.
The complex inequality, representing <span>the range of frequencies for a guitar tuned to "concert pitch"</span> is given by
It’s going to be north in the east
Answer:
The correct answer is option c) y = 6
Step-by-step explanation:
It is given that|10-5y| =20
<u>Check each option</u>
a) y = 2
|10 - 5y| = |10 - 5 * 2| = | 10 - 10 | = 0 ≠ 20
b) y = 4
|10 - 5y| = |10 - 5 * 4| = | 10 - 20 | = |-10| = 10 ≠ 20
c) y = 6
|10 - 5y| = |10 - 5 * 6| = | 10 - 30 | = |-20| = 20
d) y = 10
|10 - 5y| = |10 - 5 * 10| = | 10 - 50 | = |-40| ≠ 20
From the above result we get the correct answer is option c) y = 6
