Find the distance between the points (4,0) and (0, 3).
Step-by-step explanation:
Given points are (4,0) and (0,3)
The distance between these two points =√(0-4)^2+(3-0)^2
=√16+9
=√25
=5 units
Answer:
(4,0) = ([tex]x_{1}[/tex],[tex]y_{1}[/tex])
(0,3)=([tex]x_{2} ,y_{2}[/tex])
distance between the points = [tex]\sqrt{(x_{1}-x_{2})^2 + (y_{1}-y_2 )^2 }[/tex]
distance=5

TRUE or FALSE
(a) In a scatterplot, the response is shown on the horizontal axis with the explanatory variable
on the vertical axis.
(b) If all of the data lie along a single line with nonzero slope, then the r
2 of the regression is
1. (Assume the values of the explanatory variable are not identical).
(c) If the correlation between the explanatory variable and the response is zero, then the slope
will also be zero.
(d) The use of a linear equation to describe the assocation between price and sales implies
that we expect equal differences in sales when comparing periods with prices $10 and $11
and periods with prices $20 and $21.
(e) The linear equation (estimated from a sequence of daily observerations):
Estimated shipments = b0 + 0.9*(Orders Processed) implies that we expect twice as many
shipments when the number of orders processed doubles only if b0 = 0.
(f) The intercept estimates how much the response changes on average with changes in the
predictor.
I'll do parts (a) through (c) to get you started
(a) False. The explanatory variable is always along the x axis, and the response variable is along the y axis. The response variable reacts to whatever the input explanatory variable is, hence the name "response".
---------
(b) True. If all data lie along a single straight line with nonzero slope, then either r = -1 or r = 1. If we have all data points on a line with some negative slope, then r = -1. If the regression slope is positive, then r = 1. Either way, it will lead to r^2 = 1 because (1)^2 = 1 and (-1)^2 = 1. In other words, there are two solutions to r^2 = 1 and they are r = -1 or r = 1. In the case of r = -1, we say the data has perfect negative linear correlation. With r = 1, the data has perfect positive linear correlation.
---------
(c) True. If r > 0, then we have some level of positive correlation which means the regression slope is positive in some way. If r < 0, then the regression slope is negative in some way. That must mean r = 0 leads to the regression slope having a flat horizontal line. This could mean one of two things: i) The points are all on or near the same curve such as a parabola, ii) The points are completely randomly scattered about. If case (i) happens, then it's better to use nonlinear regression instead of linear regression.

• El comedor del piso piloto tiene un área de 0,6 dam2 . En él se pondrán dos sofás que ocuparán 2,5 m2 de área cada uno, seis sillas de 2.500 cm2 de área cada una y una mesa de 360 dm2 . ¿Cuántos metros cuadrados libres tendrá el comedor?
Answer:
Quedan libres 49.9 metros cuadrados en el comedor.
Step-by-step explanation:
Un decámetro cuadrado ([tex]dam^{2}[/tex], antiguamente [tex]Dm^{2}[/tex]) equivale a 100 metros cuadrados, un metro cuadrado ([tex]m^{2}[/tex]) equivale a 10000 centímetros cuadrados ([tex]cm^{2}[/tex]) y 100 decímetros cuadrados ([tex]dm^{2}[/tex]). El área libre del comedor se obtiene al sustraer las áreas cubiertas de los muebles del área total del comedor:
[tex]x = 0.6\,dam^{2}\times \frac{100\,m^{2}}{1\,dam^{2}}- 2\times 2.5\,m^{2} - 6\times 2500\,cm^{2}\times \frac{1\,m^{2}}{10000\,cm^{2}} - 360\,dm^{2}\times \frac{1\,m^{2}}{100\,dm^{2}}[/tex]
[tex]x = 49.9\,m^{2}[/tex]
Quedan libres 49.9 metros cuadrados en el comedor.

Answer:
C
Step-by-step explanation:
Formula for Surface Area of cube :
6 x [tex]a^{2}[/tex]
In our case, the edges are 8, meaning would we would subsuite a with 8 in the equation. We would do 6 x 64, since [tex]8^{2}[/tex] is 64. 6 x 64 is 384, hence our answer is 384.
The Surface Area of the cube is 384 unit².
What is surface Area?Surface area is the amount of space covering the outside of a three-dimensional shape.
Given: the edge of the cube, l= 8 units
Surface area of the cube = 6*l²
= 6*8*8
= 6*64
= 384 unit²
Hence, the surface area of the cube is 384 unit².

Barry wants to make a drawling this is 1/2 the size of the original. If a tree in the original drawling is 11 inches tall and 7 inches wide, what will be the length and width of the tree in Barry's drawling?
Answer: 5.5 inches, 3.5 inches
Step-by-step explanation:
Given
Barry wants to make a drawing i.e. half the size of original

Triangle FCD is cut from parallelogram ABCD moved with left-hand side. What are the dimensions of the resulting triangle AEFD?
Answer:
The answer is below
Step-by-step explanation:
Triangle FCD is cut from parallelogram ABCD moved with left-hand side. What are the dimensions of the resulting rectangle AEFD?
A parallelogram is a quadrilateral (has four sides and four angles) in which opposite sides are parallel to each other.
A rectangle is a quadrilateral with opposite sides which are parallel and equal to each other. All the angles in a rectangle are at 90 degrees.
From the image, AD = z, FC = x, BF = w and BC = y. Hence:
EB = FC = x.
EF = AD = length = z; AE = FD = height = w
Therefore the dimensions of rectangle AEFD is length z and height w

If a point in the figure below is chosen at random, what is the probability that it is in the shaded region?
Answer:
254/324 which is about 78.4%
Step-by-step explanation:
found area of entire square to be 18² or 324
found area of 4-quarter circles - which equals one circle with radius of 9
A = 81π which is about 70
subtracted 324 and 70 to get 254
ratio of shaded to unshaded is 254 : 324
The Probability of point to lie is in the shaded region= [tex]\frac{254.34}{324}[/tex]
What is probability ?Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.
Area of square= side x side
= 18 x 18
= 324 sq. cm.
Area of 4 quadrant =4 x [tex]\frac{\pi r^{2} }{4}[/tex]
= [tex]3.14 * 9 * 9}[/tex]
= 254.34 sq. cm.
So, probability that it is in the shaded region= [tex]\frac{254.34}{324}[/tex]
