Given data, first determine which is the independent variable, x, and which is the dependent variable, y. Enter the data pairs into the regression calculator. Substitute the value for one variable into the equation for the regression line produced by the calculator, and then predict the value of the other variable.

Step-by-step explanation:
Enter data into the regression calculator.
Determine the regression equation.
Substitute the correct value for x or y into the equation.
Simplify to find the value of the other variable.

Find the value of ln(-7).

const2013 [10]

Answer:

Step-by-step explanation:

Here, we want to find the value of ln (-7)

ln is same as Log to base e and mathematically , we have it for positive numbers only

For that of negative numbers, we get undefined results

However, by the use of special mathematical

methods, we have the answer for ln (-7) as;

1.94591015 + 3.14159265 i

As we can see, for the second part, the value for the coefficient of the complex number is pi and thus, we have the correct option as A

Is y varies directly as x, and y is 18 when x is 5 witch expression can be used to find the value of y when x is 11?

Svet_ta [14]

As the variation is direct we have:
$y = k * x
$
Where,
k: proportionality constant
We must find the value of k.
For this we use the following data:
y is 18 when x is 5.
Substituting values we have:
$18 = k * 5
$
From here, let's clear k:
$k = 18/5

k = 3.6
$
Then, replacing values we have:
$y = 3.6 * x
$
For x = 11 we have:
$y = 3.6 * 11

y = 39.6$
Answer:
An expression that can be used to find the value of y when x is 11 is:
$y = 3.6 * x
$
When x = 11 we have:
$y = 39.6$
