The r-value is that represents the weakest correlation is D. -0.05
What is linear regression line?The connection between the independent (x) and dependent (y) variables in the graph can be graphically represented using regression lines.
In a linear model, the terms are added rather than multiplied, divided, or provided as a non-algebraic function, as has been the case thus far in this section. Analysis of experimental, monetary, and biological data as well as complex system prediction are both possible using linear modelling.
A statistical technique used to build a linear model is called linear regression. The model explains how one or more independent variables Xi relate to a dependent variable y (also known as the response) (called the predictors). The distance between each data point and the regression line is called a residual.
Given data ,
The r-value is a measure of the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, where -1 indicates a perfect negative correlation, 0 indicates no correlation, and 1 indicates a perfect positive correlation.
Among the given options, the r-value that represents the weakest correlation is D. -0.05. This is because the absolute value of -0.05 is small compared to the other options, indicating a weaker linear relationship between the variables.

Answer:
x = 29
Step-by-step explanation:
Given:
m<PQS = 107°
m<RQS = 49°
m<PQR = (2x)°
Required:
Value of x
Solution:
m<RQS + m<PQR = m<PQS (angle addition postulate)
Plug in the values
49 + 2x = 107
Subtract 49 from each side
2x = 107 - 49
2x = 58
Divide both sides by 2
x = 58/2
x = 29

Answer:
42.5 units²
Step-by-step explanation:
Total height of rectangle = 3.5 + 2 = 5.5 units
Total area (without triangles removed) = 5.5 x 9.0 = 49.5 units²
The measurements and area of the triangles removed are equal to those on the diagram, so calculate the area of the triangles and subtract them from the total area.
Left: (0.5)(2)(2) = 2 units²
Right: (0.5)(5)(2) = 5 units²
Area: 49.5 - 2 - 5 = 42.5 units²

Find the area of the figure. (Sides meet at right angles.)
Answer:
56m²
Step-by-step explanation:
separate shape into 2 shapes (i did 1 rectangle at top and 1 square at bottom.
find area separately so for rectangle, it would be 4x10 = 40m²
square = 4x4 = 16m²
then add together areas
16 + 40 = 56m²
Answer:
The total area is 56m²
Step-by-step explanation:
First divide the figure into two different parts; now we have a square and a rectangle. The square has a height of 4 and width of 4 so multiply both numbers to get your area. The rectangle has a height of 4 and an unknown width, with the information we have we know the width of the rectangle has at least 3m² on one side and 3m² on the other. Where we divided the figures we see the bottom width of the square is 4 which is the missing length to complete the rectangles width. Add 3 plus 3 plus 4 and you have your width. Since now we know that the width of the rectangle is 10 we can use the formula to get the area: 10 times 4 equals 40 the area of the rectangle is 40m².
Area of square: 16m²
Area of rectangle: 40m²
Add the areas of both shapes and that makes the area of the shape previously shown.
The total area is 56m²

Tanya wants to test the theory that the exterior angles of a
triangle add up to 360°. She draws triangle ABC and finds all
the angles in the triangle.
PLEASE HELP!!
Answer:
[tex]f + e + d = 360^o[/tex]
Step-by-step explanation:
The question is incomplete, as what is required is not stated and the triangle is not given.
So, I will solve generally.
The proof is as follows (see attachment for triangle)
From the attachment, we have:
[tex]a + f = 180[/tex]
[tex]b + e = 180[/tex]
[tex]c + d = 180[/tex]
Make f, e and d the subject
[tex]f = 180 - a[/tex]
[tex]e = 180 - b[/tex]
[tex]d = 180 - c[/tex]
Add up the equations
[tex]f + e + d = 180 -a + 180 - b + 180- c[/tex]
Collect like terms
[tex]f + e + d = 180 + 180+ 180-a- b - c[/tex]
[tex]f + e + d = 540-a- b - c[/tex]
We have:
[tex]f + e + d = 540-(a+ b + c)[/tex]
[tex]a + b + c \to 180[/tex] --- angles in a triangle
So, we have:
[tex]f + e + d = 540-180[/tex]
[tex]f + e + d = 360^o[/tex] --- proved

Lalasa and Yasmin are designing a triangular banner to hang in the school gymnasium. They first draw the design on paper. The triangle has a base of 5 inches and a height of 7 inches. If 1 inch on the drawing Is equivalent to 1.5 feet on the actual banner, what will the area of the actual banner be? A 52.5 ft2 B 17.5 ft2 39.375 ft2 D 78.75 ft2
Find the actual Dimensions of the triangle.
Multiply the size of the triangle on paper by 1.5 feet per inch:
Width = 5 x 1.5 = 7.5 feet.
Height= 7 x 1.5 =10.5 feet
Area of a triangle is 1/2 x base x height:
Area = 1/2 x 7.5 x 10.5 = 39.375 square feet.
Answer: 39.375 square feet.
The area of the actual banner is 39.375 feet²
What is scaling?
Scaling is used to increase or decrease the size of a figure so as to create an image.
Given that 1 inch on the drawing Is equivalent to 1.5 feet on the actual banner, hence:
Base = 5 in * 1.5 feet per in = 7.5 feet
Height = 7 in * 1.5 feet per in = 10.5 feet
Area of the actual banner = (1/2) * 7.5 * 10.5 = 39.375 feet²
The area of the actual banner is 39.375 feet²

Samantha is selling raffle tickets for $1.50 each. At the end of the night she knows that she has made at most $84 in sales. If n represents the number of tickets Samantha sold, then which inequality below models the information given?
Answers
1.50n>84
1.50n<84
1.50n≥84
1.50n≤84
Answer:
1.50n≤84
Step-by-step explanation:
The statement indicates that Samantha knows that she has made at most $84 in sales and this means that that is the higher amount she thinks she can have. So, the total amount could be less than that or equal to that. Also, the total amount she has would be the result of multiplying the price per ticket for the number of tickets sold. Moreover, this amount would be less than or equal to 84 and the symbol that represents less than or equal to is ≤. According to this, the inequality that would model the information is: 1.50n≤84.

The volume of both of these trapezoidal prisms is 24 cubic units. Their heights are 6 and 8 units, as labeled. What is the area of a trapezoidal base of the prism with a height of 6 units?
Answer:
area of a trapezoidal base of each prism with heights 6 and 8 units are 4 square units and 3 square units respectively
Step-by-step explanation:
Let us first be aware of formula of volume for any regular geometrical figure.
Fundamental formula for volume for any regular geometrical figure is.
volume = area of cross section of object* height of object (A)
In the problem stated area of cross section of object will be area of a trapezoidal base.
Given in the question is
Volume of both the trapezoidal prisms = 24 cubic units
*************************************************************************************
For prism with height 6 unit
Substituting the value of height and volume in formula for trapezoidal prisms
24 = 6 * area of a trapezoidal base
=> area of a trapezoidal base = 24/6 = 4 square units
*************************************************************************************
For prism with height 8 unit
Substituting the value of height and volume in formula for trapezoidal prisms
24 = 8 * area of a trapezoidal base
=> area of a trapezoidal base = 24/8 = 3 square units
*************************************************************************************
Therefore area of a trapezoidal base of each prism with heights 6 and 8 units are 4 square units and 3 square units respectively.
A person invested $440 in an account growing at a rate allowing the money to double every 8 years. How long, to the nearest tenth of a year would it take for the value of the account to reach $2,860?
9514 1404 393
Answer:
21.6 years
Step-by-step explanation:
The first statement tells you the account balance can be modeled by ...
A = 440(2)^(t/8) . . . . . where t is in years
We want to find t when A = 2860
2860 = 440(2^(t/8))
6.5 = 2^(t/8) . . . . . . . . . . divide by 440
log(6.5) = (t/8)log(2) . . . . take logarithms
t = 8·log(6.5)/log(2) ≈ 21.604 . . . . . . divide by the coefficient of t; evaluate
It would take about 21.6 years for the value to reach $2,860.
