Scatterplot 2
Step-by-step explanation:
SP1: All a straight line with equation of y=3 except for 1 point.
SP2: All points are on the line of y=2x-1
SP3: The trend line is y=2x-1, however, a lot of points aren't on it
SP4: Same as SP3, but there is an additional outlier at x=1.8
SP2 looks to be the strongest correlation based on these descriptions.

If a point in the figure below is chosen at random, what is the probability that it is in the shaded region?
Answers
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]

u = 9
Step-by-step explanation:
5u + 11 = 56
Subtract 11 from each side.
5u + 11 - 11 = 56 - 11

Tara uses 8.8 pints of white paint and blue paint to paint her bedroom walls. 4 5 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?
Answers
Answer:
the blue paints of 1.76 pints is used to paint her bedroom walls
Step-by-step explanation:
Given that
Tara uses 8.8 pints of white paint
And, the 4 by 5 of this amount represent the white paint
We need to find out the number of paint used by the blue paint
So,
= 8.8 - (8.8 × 4 ÷ 5)
= 8.8 - 7.04
= 1.76 pints
Hence, the blue paints of 1.76 pints is used to paint her bedroom walls

A middle school took all of its 6th grade students on a field trip to see a ballet at a theater that has 1300 seats. The students filled 1001 of the seats in the theater. What percentage of the seats in the theater were filled by the 6th graders on the trip?
Answers
I like to use ratios and cross multiply for problems like this. Take the part (1001) over the whole (1300), and that equals x percent of 100 percent.
1001/1300 = x/100
100100 = 1300x

Answers
Answer: 20 boxes of chocolates
Step-by-step explanation:
First find out the total number of chocolates he has:
= 25 boxes * 24 chocolates per box
= 600 pieces of chocolate
The number of boxes needed if the chocolates are packed 30 in a box is:
= Total number of chocolates / Number of chocolates per box
= 600 / 30
= 20 boxes of chocolates

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.
Answers
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.
The parabola in the image has its focus at (4,3). Its directrix is the line y=1. The point (8,6) is on the parabola.

The length and width of the original drawing are 11 inches and 7 inches respectively.
So, the intended drawing is obtained by multiplying the original dimensions by [tex]\frac{1}{2}[/tex]
The length of barry's drawing is
[tex]\Rightarrow 11\times \frac{1}{2}\\\\\Rightarrow 5.5\ \text{inches}[/tex]
