Answers
Answer:
It's A. The points all lie very close to the line of fit, and the line is decreasing.
Step-by-step explanation:
The points all lie very close to the line of fit, and the line is decreasing option (A) is correct.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
It is given that:
The value of the correlation coefficient r = -0.97
As we know,
If the value of the correlation coefficient is positive it represents the line of best-fit increasing.
If the value of the correlation coefficient is negative it represents the line of best fit decreasing.
If the value of r is close to 1 then we can say that the correlation between the two variables is very strong.
Thus, the points all lie very close to the line of fit, and the line is decreasing option (A) is correct.

Teresa purchased a prepaid phone card for $15 . Long distance calls cost 24 cents a minute using this card. Teresa used her card only once to make a long distance call. If the remaining credit on her card is $3.96 , how many minutes did her call last?
Answers
Answer:
46 minutes
Step-by-step explanation:
Teresa purchased a prepaid phone for $15
Long distance calls cost 24 cents a minute using this card
She used the card just once to make a long distance call
The remaining credit on her card was $3.96
Therefore the minutes in which her call lasted can be calculated as follows
Let x represent the minutes
15 - 24/100x= 3.96
15-0.24x= 3.96
-0.24x= 3.96-15
-0.24x= -11.04
x= 11.04/0.24
x = 46
Hence Teresa call lasted for 46 minutes

a line passing through the points (1, 1) and (3, 11)
a line passing through the points (2. -6) and (4, -16)
Answers
Answer:
a line passing through the points (2, -6) and (4, -16)
Step-by-step explanation:
y=-5x+4
you plug in the x value and put the y value on the left side of the equation
for example
-6 = -5(2) + 4
then solve to see if it works
-5(2) = -10 + 4 = -6
(2, -6) works
-16 = -5(4) +4
-5(4) = -20
-20 + 4 = -16
(4, -16) works

Please classify the following equations as parallel, perpendicular, intersecting, or coinciding (same line):
y = 3x + 2
9x - 3y = -6
Answers
Answer:
Intersecting
Step-by-step explanation:
Parallel lines means it will have the same slope, and perpendicular means the slope will be it's reciprocal, so the slope would be 1/3 x instead of 9x. Conciding means it's the exact same equation, so the answer has to be intersecting.

On her way to visit Horace Mann University, Casey stopped by Mount Rushmore in South Dakota. The park ranger gave a talk that described the history of the monument and provided some interesting facts. Casey could not believe that the carving of George Washington’s face is 60feet tall from his chin to the top of his head!
However, when a tourist asked about the length of Washington’s nose, the ranger was stumped! Casey came to her rescue by measuring, calculating and getting an answer.
How did Casey get an answer?
Answers
Answer:
using a proportion relating nose length to head height
Step-by-step explanation:
Casey measured the nose length, and found the fraction that was of the head height. Then Casey found the same fraction of 60 feet to find the actual nose length.
__
Casey could use a photograph, poster, postcard, or a ruler held at arm's length, to make the necessary measurements.

Which statement best describes the function?
Answers
example of absolute value
F( x )=| x |
Step-by-step explanation:
In mathematics, the absolute value or modulus of a real number x, denoted |x|, is the non-negative value of x without regard to its sign. Namely, |x| = x if x is positive, and |x| = −x if x is negative (in which case −x is positive), and |0| = 0. For example, the absolute value of 3 is 3, and the absolute value of −3 is also 3. The absolute value of a number may be thought of as its distance from zero.

Step-by-step explanation:
A rocket is launched from a tower. The height of the rocket, why in feet is related to the time after launch, X and seconds, by the given equation. Using this equation find out the time at which the rocket will reach its max, to the nearest 100th of a second y=-16x + 152x + 74
Answers
Given:
Consider the height of the rocket, in feet after x seconds of launch is
[tex]y=-16x^2+152x+74[/tex]
To find:
The time at which the rocket will reach its max, to the nearest 100th of a second.
Solution:
We have,
[tex]y=-16x^2+152x+74[/tex]
It is a quadratic polynomial with negative leading coefficient. So, it is a downward parabola.
Vertex of a downward parabola is the point of maxima.
To find the time at which the rocket will reach its max, we need to find the x-coordinate of the vertex.
If a quadratic function is [tex]f(x)=ax^2+bx+c[/tex], then the vertex is
[tex]Vertex=\left(-\dfrac{b}{2a},f\left(-\dfrac{b}{2a}\right)\right)[/tex]
Here, [tex]a=-16,b=152,c=74[/tex].
So,
[tex]-\dfrac{b}{2a}=-\dfrac{152}{2(-16)}[/tex]
[tex]-\dfrac{b}{2a}=-\dfrac{152}{-32}[/tex]
[tex]-\dfrac{b}{2a}=4.75[/tex]
So, x-coordinate of the vertex is 4.75.
Therefore, the rocket will reach its max at 4.75 second.
