Joseph has a bag of 4 marbles. There are 2 green marbles, 1 yellow marble, and 1 purple marble.
Which list gives the sample space for pulling 2 marbles from the bag with replacement?
List 1
List 2
List 3
List 4
Answers
The list that gives the sample space for pulling 2 marbles from the bag with replacement is given as follows:
List 4.
What is a sample space?A sample space is a set that contains all possible outcomes in the context of an experiment.
The fact that the experiment is with replacement means that for each of the two marbles, there are two possible outcomes.
Then, applying the Fundamental Counting Theorem, the total number of outcomes is given as follows:
4 x 4 = 16.
This means that the correct list is either the list 3 or the list 4.
As there is replacement, it is possible to take two purple marbles, even though there is only one purple marble, as the same can be taken with replacement, and thus the correct list is given by list 4.

What is the approximate number of minutes that avery spends in extra circular activities
Answers
The approximate number of minutes that Avery spends on the extra curricular activities are 122 minutes.
Given that Avery spent 10 minutes outside, 64 minutes in riding her bike, 48 minutes on the trampoline.
We have to calculate the approximate time that Avery spends on extra curricular activities.
Time spent by Avery outside=10 minutes
Time spent by Avery in riding her bike=64 minutes
Time spent by Avery on trampoline=48 minutes
Total time spent by Avery on extra curricular activities is equal to 10+64+48

Answer:
y-intercept at (0,3)horizontal asymptote of y=0no x-interceptStep-by-step explanation:
The y-intercept of f(x) is (0,1), so the y-intercept of g(x) is (0,3).
f(x) has a horizontal asymptote at y=0. and so does g(x).
f(x) does not have an x-intercept, and neither does g(x).
Answer:
y-intercept at (0, 3)
horizontal asymptote of y = 0
no x-intercept
Step-by-step explanation:

y-intercept: the point(s) at which the curve crosses the y-axis (when x=0).
x-intercept: the point(s) at which the curve crosses the x-axis (when y=0).
Asymptote: a line that the curve gets infinitely close to, but never touches.

Explanation:
Triangle ABC is similar to triangle DEF. The order of the lettering is important because it tells us how the letters pair up.
A and D are the 1st letters, so they pair upB and E are the 2ndletters, so that's another pairC and F are the 3rd letters, which is the final pair of pointsBased on that, we can determine how the segments pair up
AB and DE correspond to each other. The segments are composed of the 1st and 2nd points.BC and EF correspond as well. The segments use the 2nd and 3rd points.AC and DF correspond also. They use the 1st and 3rd points.We want to find how long EF is, which means we'll involve BC = 17 since it is paired with it.
The diagram shows that AC = 14 and DF = 3, which is another pair we'll use
--------------------------
The key takeaway is that
AC = 14 and DF = 3 pair up togetherBC = 17 and EF also pair up togetherThose two facts lead to the steps below
[tex]\frac{AC}{DF} = \frac{BC}{EF}\\\\\frac{14}{3} = \frac{17}{EF}\\\\14*EF = 3*17\\\\14*EF = 51\\\\EF = \frac{51}{14}\\\\EF \approx 3.642857\\\\EF \approx 3.6\\\\[/tex]

x intercept:-

option C
Question 1: Given a(x) = x + 5, what are the x-intercepts and y-intercepts of a?
a. x-intercept at (-5,0), y-intercept at (0,5)
b. x-intercept at (5,0), y-intercept at (0,-5)
c. x-intercept at (0,5), y-intercept at (5,0)
Answer: a
The x-intercept is the place where the graph touches the x-axis. Since the equation for the x-axis is just y=0, we can put in 0 for y to get it.
0 = x + 5
x = -5
Since x is -5 and y is 0, the x-intercept is at (-5,0).
The y-intercept is the place where the graph touches the y-axis. Since the equation for the y-axis is just x=0, we can put in 0 for x to get it.
y = 0 + 5
y = 5
Since x is 0 and y is 5, the y-intercept is at (0,5).
Question 2: Given b(x) = 2x + 1, what are the x-intercepts and y-intercepts of b?
a. x-intercept at (0.5, 0), y-intercept at (0, 2)
b. x-intercept at (-0.5,0), y-intercept at (0, 1)
c. x-intercept at (0, -0.5), y-intercept at (1,0)
Answer: b
The x-intercept is the place where the graph touches the x-axis. Since the equation for the x-axis is just y=0, we can put in 0 for y to get it.
0 = 2x + 1
x = -0.5
Since x is -0.5 and y is 0, the x-intercept is at (-0.5,0).
The y-intercept is the place where the graph touches the y-axis. Since the equation for the y-axis is just x=0, we can put in 0 for x to get it.
y = 2(0) + 1
y = 1
Since x is 0 and y is 1, the y-intercept is at (0,1).
Question 3: Given c(x) = 3x - 2, what are the x-intercepts and y-intercepts of c?
a. x-intercept at (-2,0), y-intercept at (0,2/3)
b. x-intercept at (0, 2), y-intercept at (3/2, 0)
c. x-intercept at (2/3, 0), y-intercept at (0, -2)
Answer: c
The x-intercept is the place where the graph touches the x-axis. Since the equation for the x-axis is just y=0, we can put in 0 for y to get it.
0 = 3x - 2
x = [tex]\frac{2}{3}[/tex]
Since x is 2/3 and y is 0, the x-intercept is at (2/3,0).
If the equation is in the form y = mx + b, the y-intercept will be b. The y-intercept also crosses the graph x = 0, so the y-intercept is (0, -2).
Question 4: Given d(x) = -x + 1, find the x-intercepts and y-intercepts of d.
a. x-intercept at (0, 1), y-intercept at (1,0)
b. x-intercept at (1, 0), y-intercept at (0, -1)
c. x-intercept at (1,0), y-intercept at (0,1)
Answer: c
The x-intercept is the place where the graph touches the x-axis. Since the equation for the x-axis is just y=0, we can put in 0 for y to get it.
0 = -x+1
x = -(-1) = 1
Since x is 1 and y is 0, the x-intercept is at (1,0).
If the equation is in the form y = mx + b, the y-intercept will be b. The y-intercept also crosses the graph x = 0, so the y-intercept is (0, 1).
Question 5: Given f(x) = -7x+5, find the x-intercepts and y-intercepts of f.
a. x-intercept at (-5/7, 0), y-intercept at (0, -7/5)
b. x-intercept at (5, 0), y-intercept at (0, 5/7)
c. x-intercept at (5/7, 0), y-intercept at (0, 5)
Answer: c
The x-intercept is the place where the graph touches the x-axis. Since the equation for the x-axis is just y=0, we can put in 0 for y to get it.
0 = -7x+5
x = -5/-7= 5/7
Since x is 5/7 and y is 0, the x-intercept is at (5/7,0).
If the equation is in the form y = mx + b, the y-intercept will be b. The y-intercept also crosses the graph x = 0, so the y-intercept is (0, 5).

Answer:
The slope of the line segment CD is ( - [tex]\frac{8}{9}[/tex] )
Step-by-step explanation:
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )
Coordinates of the midpoint are
( [tex]\frac{x_{1} +x_{2} }{2}[/tex] , [tex]\frac{y_{1} +y_{2} }{2}[/tex] )
The slope of a line segment with coordinates of the ends
( [tex]x_{1}[/tex] , [tex]y_{1}[/tex] )
( [tex]x_{2}[/tex] , [tex]y_{2}[/tex] )
is m = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
~~~~~~~~~~~~~
Point D is the midpoint of a segment AB
A ( 4 , 12 )
B ( - 6 , - 8 )
( [tex]\frac{-6+4}{2}[/tex] , [tex]\frac{-8+12}{2}[/tex] ) = ( - 1 , 2 )
D ( - 1 , 2 )
C ( 8 , - 6 )
[tex]m_{CD}[/tex] = [tex]\frac{-6-2}{8-(-1)}[/tex] = - [tex]\frac{8}{9}[/tex]
