Six sided dice is rolled 60 times what is the theoretical probability of rolling a three or four?
Answer:
10
Step-by-step explanation:
It is much easier to do this for one die. There is a 1/6 chance that a 3 occurs on a six-sided die. Another way to say that is that the expected number of 3’s that occur on a roll of a six sided die is 1/6. If we let X be 1 if a 3 occurs on the roll and 0.
Now, if the die is rolled 60 times, then we have 60 different values X1, X2,…,X60
Of course, this shouldn’t be all that surprising. After all, we threw the die 60 times, and there are 6 faces, so it seems reasonable that for a fair die, each face should come up about 10 times.

List at least 3 ways you can use a table or a graph to determine if a function is linear or nonlinear.
Answer:
1) if you use the graph, it should go in a straight line, if it does, it’s linear.
2) if you use a table, you can see to make sure the numbers go up/down at the same rate
3) if you have a graph and a table, you could always compare both, and make sure they’re both linear
A high school track is shaped as a rectangle with a half circle on either side. Jasmine plans on running three laps. How many yards will Jasmine run? Use 3.14 for Pi.
A. 248.5 yd
B. 490.5 yd
C. 725.5 yd
D. 745.5 yd
Step-by-step explanation:
= 25 yards ; r = 25/2 = 12.5 yards
circumference of two semicircle = circumference of circle
= 2πr = 2*3.14*12.5 = 78.5 yards
Perimeter of school truck = 78.5 + 85 + 85 = 248.5 yards
Distance traveled by Jasmine = 3* 248.5 = 745.5 yards

Write a quadratic function whose graph has a vertex of (3,2) and passes through the point (4,7). f(x)=
Answer:
y=5(x-3)^2+2
Step-by-step explanation:
You plug the point into f(x)=a(x-3)^2+2... that already has already been solved for the vertex that you want. Then you swap it out for the solution you have solved for.
The required function is [tex]f(x)=5(x-3)^2+2[/tex].
Important information:
Vertex of a quadratic function is (3,2).The graph passes through the point (4,7).Quadratic function:The vertex form of a quadratic function is:
[tex]f(x)=a(x-h)^2+k[/tex]
Where, [tex]a[/tex] is a constant and [tex](h,k)[/tex] is vertex.
Substitute [tex]h=3,k=2[/tex].
[tex]f(x)=a(x-3)^2+2[/tex] ...(i)
The graph passes through the point (4,7). Substitute [tex]x=4, f(x)=7[/tex] in (i).
[tex]7=a(4-3)^2+2[/tex]
[tex]7=a+2[/tex]
[tex]7-2=a[/tex]
[tex]5=a[/tex]
Substitute [tex]a=5[/tex] in (i).
[tex]f(x)=5(x-3)^2+2[/tex]
Therefore, the required function is [tex]f(x)=5(x-3)^2+2[/tex].
