Choose exactly two answers that are correct.

A.linear association
B.negative association
C.nonlinear association
D.positive association
(please help.. it's urgent. thanks <3)

Answers

The higher value of X is associated with a lower value of Y so this is a negative association. It is also a nonlinear association because the ratio of change is not constant. For example X changes from 1 to 2, Y changes from 120 to 115 opposed to X changes from 5 to 6 while Y changes from 89 to 40.

Given f (x) and g(x)+k look at the graph below and determine the value of K

Answers

Answer:

k=5

Step-by-step explanation:

Let's find the equation for both lines. For the line in blue we know that passes through points (0,-2) and (3,-1) with this information we can use the formula of the line:

$y-y_1=(y_2-y_1)/(x_2-x_1) (x-x_1)$

so making the susbtitution we get:

$y-(-2)=(-1-(-2))/(3-0)(x-0)$

$y=(1)/(3)x-2$

For the red line we know that passes through points (0,3) and (3,4) doing the same steps as above we get that

$y-(3)=(4-3)/(3-0)(x-0)$

$y=(1)/(3)x+3$

the value of k is 5 that's why because we need to move 5 units along the y axis to reach the 3 in the red line

The value of K is 5 because its going up 5 from the f(x) graph

The volume of a right cone is 3975pi units^3. f its radius measures 15 units, find its height.

Answers

Answer:

Step-by-step explanation:

right cone equation: $V=\pi r^(2) (h)/(3)$ where V is volume, r is radius, and h is height.

Solve this equation
2^(x+3) = 512

Answers

2^(x + 3) = 512
ln(2^(x + 3)) = ln(512)
(x + 3)ln(2) = ln(512)
ln(2) ln(2)
(x + 3)ln(2) = ln(2^9)
ln(2) ln(2)
(x + 3)ln(2) = 9ln(2)
ln(2) ln(2)
x + 3 = 9
- 3 - 3
x = 6

x=1,the equation=16 ; x=2,the equation=32; by such analogy,when x=6,the equation=512. so the answer is x=6.

How do you convert 2 1/7 to a improper fraction

Answers

2 1/7 is converted toan improper fraction as 15/7.

What are improper fractions?

A fraction that has the numerator higher than or equal to the denominator is said to be inappropriate.
A fraction, such as 5/4, is when the numerator exceeds the denominator.
Examples are 9/2, 8/5, 10/3, etc.
Multiply the denominator by the full number to find the improper fraction's numerator.
Add this to the numerator after that.
The same will apply to the denominator.

So, the given fraction is:

2 1/7

Now, convert it to an improper fraction as follows:

2 1/7
14+1/7
15/7

Therefore, 2 1/7 is converted to an improper fraction as 15/7.
