Answer:
=−2xy+3x+2y
Step-by-step explanation:
this is what i get in calculating
We are given
(a, b) ---------------> (a, −b)
we can see that
x-values of both points are 'a'
which is same
while y-value of first =b
y-value of second =-b
so, y becomes as -y
and we know that
when a function is reflected about x-axis
then y becomes -y
so, option-C.................Answer
Answer:
a) -0.5
Step-by-step explanation:
Correlation
- Correlation is a technique that help us to find or define a 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
- A negative correlation means with increase in one quantity the other quantity decreases.
- Values between 0 and -0.3 tells about a weak negative linear relationship, values between -0.3 and -0.7 shows a moderate negative correlation and a correlation value of of -0.7 and -1.0 states a strong negative linear relationship.
Anxiety symptoms and life satisfaction are negatively correlated. As life satisfaction increases the anxiety symptoms decreases.
Thus, a moderate correlation between them can be expressed by a correlation coefficient of -0.5
Answer:
The total number of books is 1020.
Step-by-step explanation:
Denote the books by their first letter.
From the provided information:
Compute the expression of <em>T</em> as follows:
Compute the value of <em>C</em> in terms of <em>A</em>:
Compute the value of <em>A</em> as follows:
Use expressions (i) and (ii):
Compute the value of <em>T</em> as follows:
Thus, the total number of books is 1020.
Answer:
y=12
Step-by-step explanation:
Lets write out the equation so it easy to work with.
7y=84
Divide both sides by 7
7y/7=84/7
Divide
y=12
