y=
Identify the correlation coefficient. Round your answer to the nearest thousandths.
Interpret the correlation coefficient.
b. Interpret the slope of the line of best fit.
c. A patient who weighs 140 pounds is prescribed 135 milligrams of medicine. How does this affect the line of best fit? Explain.
The equation of the line of best fit in the table given regarding the weights will be y = 0.77x - 1.1
How to illustrate the table?From the information given, the equation of the line of best fit in the table given regarding the weights is given and the correlation coefficient is 0.99.
The relationship is strongly positive as it's close to 1. The slope of the best fit gives the change in dosage for for an increase in the weight of the patient.
When a patient who weighs 140 pounds is prescribed 135 milligrams of medicine, it affects the line of best fit as it increases the intercept but decreases the slope.

A room is 3m high and has a volume of 60m3 calculate area of floor of the room
[tex]height = 3m[/tex]
[tex]volume = 60 {m}^{3} [/tex]
to find:the area of the room.
solution:[tex]l \times w \times h = 60[/tex]
[tex]l \times w \times 3 = 60[/tex]
[tex]l \times w = 20 {m}^{2} [/tex]
therefore, the area of the room is 20 square meters.
Quadrilateral QRST is dilated by a factor of 2 with the center of dilation at the origin. What are the coordinates of quadrilateral Q'R'S'T'?
A) Q' (4, 4), R' (-4, 4), S' (-4, -4), T' (4, -4)
B) Q' (-1, 1), R' (1, 1), S' (1, -1), T' (-1, -1)
C) Q' (-4, 4), R' (4, 4), S' (4, -4), T' (-4, -4)
D) Q' (-3, 3), R' (3, 3), S' (3, -3), T' (-3, -3)
Answer:
C) Q' (-4, 4), R' (4, 4), S' (4, -4), T' (-4, -4)
Step-by-step explanation:
Original:
Q = (-2, 2)
R = (2, 2)
S = (2, -2)
T = (-2, -2)
After multiplying each coordinate by 2:
Q' = (-4, 4)
R' = (4, 4)
S' = (4, -4)
T' = (-4, -4)

which function corresponds to the graph below? help pleaseee!
Answer:
A
Step-by-step explanation:
It is A because the negative in front of the 4 shows the curve was REFLECTED over the x-axis. The +1/2 in the parenthesis with the x shows the curve was translated (shifted or slid) to the LEFT 1/2 unit and the +3 at the end of the equation shows the whole thing was translated/shifted/slid UP 3 units. These transformations all together make the equation in A match the curve given.

How do we find coterminal angles for
degrees? Radians?
Answer:
To find coterminal angles, add or subtract 360 degrees of the terminal angle as many times possible.
To find radians, use this formula:
Degrees × π/180°
Coterminal angles point in the same exact direction.
In degree mode, you can add on 360 degrees to get a coterminal angle.
Example: 90 degrees is coterminal to 450 degrees because 90+360 = 450. Both angles 90 and 450 point directly north.
You can also subtract 360 from the angle to get a coterminal counterpart.
Example: Given the angle 700, it is coterminal to 340 since 700-360 = 340
This process of adding or subtracting 360 can be done as many times as you like.
------------------------------
For radian mode, you'll add or subtract 2pi radians to get a coterminal angle. This is because 2pi radians = 360 degrees by definition.
Examples:
pi is coterminal to 3pi because pi+2pi = 3pi, both point directly westpi/4 is coterminal to 9pi/4 because pi/4 + 2pi = pi/4 + 8pi/4 = 9pi/421pi/4 is coterminal to 13pi/4 because 21pi/4 - 2pi = 21pi/4 - 8pi/4 = 13pi/4How do you find A to C?

[tex]AC = 12.12[/tex]
Step-by-step explanation:
Step 1: Determine side AC
[tex]Pythagorean\ theorem[/tex] → [tex]a^2 + b^2 = c^2[/tex]
[tex](AC)^2 + (CB)^2 = (AB)^2[/tex]
[tex](AC)^2 + (7)^2 = (14)^2[/tex]
[tex](AC)^2 + 49 = 196[/tex]
Step 2: Subtract 49 from both sides
[tex](AC)^2 + 49 - 49 = 196- 49[/tex]
[tex](AC)^2 = 147[/tex]
Step 3: Square root both sides
[tex]\sqrt{(AC)^2} = \sqrt{147}[/tex]

every subsequent day. Find the total number of bags sold in seven days.
48
84
65,532
65,535
The total number of the bags sold by the shopkeeper will be 65532.
What is number series?The sequence formed by using the numbers is termed as the number series.So in this question from day one to day seven each day the sold items are multiplied by 4.
So the mathematical expression will be given as:
[tex]=(12\times 4^0)+(12\times 4^1)+(12\times 4^2)+(12\times 4^3)+(12\times 4^4)+(12\times 4^5)+(12\times 4^6)[/tex]

A table has a length of 9 and a width of 4. What is the perimeter?
Answer:
26
Step-by-step explanation:
Assume the table is a rectangle.
A rectangle has 2 sides with the length of the length and 2 sides with the length of the width.
perimeter = sum of the lengths of the sides
perimeter = 9 + 9 + 4 + 4
perimeter = 26
Answer:
26
Step-by-step explanation:
Assuming the table is rectangular...
Rectangles = 4 sides
2 sides = 9
Other 2 sides = 4
Perimeter = adding up the sides
9+9+4+4=26
