637 is the answer because our value is 980 we all know the unknown value with x for the step above 980 and 100% and 65% is the result in a pair of a simple equations
Answer:
13) 10b^2a^4
14) -5y^3+35y^2-10y
Answer:
Option A is correct.
The value of r = -0.7 represents the strongest negative correlation.
Step-by-step explanation:
A correlation is a value that describes a relationship between two things or variables.
Strongest Negative Correlation says that closer a negative correlation to -1, the stronger the relationship between the two variables.
From the options, we have only two negative values i.e, r= -0.7 and r= -0.22.
We have to find the strongest negative correlation r-value.
By the definition, you can see that -0.7 is very closer to -1 ,
therefore, the value of r = -0.7 represents the strongest negative correlation.
B IS THE ANSEWER TO THE PROBLEM
<h2>'
' in the form of
- b.</h2>
Step-by-step explanation:
We have,
+ 8x + 15
To express
+ 8x + 15 in the form of
- b = ?
∴
+ 8x + 15
Adding and subtracting 1, we get
=
+ 8x + 15 + 1 - 1
=
+ 8x + 16 - 1
=
+ 2(x)(4) +
- 1
Using the algebraic identity,

= 
Thus,
in the form of
- b.
