The two dot plots below compare the forearm lengths of two groups of schoolchildren:
Based on the visual inspection of the dot plots, which group appears to have the longer average forearm length?
Group X, because no child in the group has a forearm length longer than 12 inches
Group X, because four children in the group have the least forearm length of 10 inches
Group Y, because a child in the group has the least forearm length of 10 inches
Group Y, because six children have a forearm length longer than 12 inches

A or group X

- anonymous

B sorry

- anonymous

Group X, because four children in the group have the least forearm length of 10 inches is answer

What is the initial value of the function represented by this table?
x y
0 3

oh i got it, hope this help:
0 + 3 =3
1+ 4 =5
2+5 =7
3+6=9
5+7=12

- anonymous

so B

@_greatmath7 I have to disagree with your answer on "The two dot plots below compare the forearm lengths of two groups of schoolchildren:
Based on the visual inspection of the dot plots, which group appears to have the longer average forearm length?"

- muscrat123

yea actually now i think it is d. thx for the catch! @heretohelpalways

There is a 90% chance of rain tomorrow and a 30% chance that the baseball game will be postponed. What is the probability that it will rain tomorrow and the baseball game will be postponed?
3%
6%
27%
60%

- anonymous

P(A & B) = P(A) * P(B)
= .90 * .30 = .27

- anonymous

So C

- muscrat123

positive?

- anonymous

Yes

I am great at percents and fractions

Function "P" represents a line, you can determine what geometric body it forms by looking at the variable with the highest exponent, and since both x and y have an exponent of "1" we can conclude that funciton "P" represents a line.
A line is all the set of points that form a colineal vector with \(\vec u\) which is called the "director vector" of the line, and the line is composed by all the points that form a colineal vector with \(\vec u \) on the axis defined by the direction of the vector and any given point.
That+s pretty much all there is to "lines", but what is most important is that lines can be respresented with equation that follow a certain structure, there are a total of 8 forms to express the equation of a line, but you only need to worry about two of them; The general form of the line : \(ax+by+c=0\) and the "point-slope form": \(y=mx+c\)
You can see that the line represented by the function "P" follows the structure of the second structure: \(y=mx+c\) where "m" is the slope and "c" is the y-interception.
This means, that only observing the equation of the function you can pull out the slope and the y-interception of the function "P".
\[y=5x+3\]
We can see that it follows the structure \(y=mx+c\) so therefore, we can see that the slope of function "P" is 5 and the y-intercept being "3".
