Answer:
10 in 60 chance, or simplified to 1 / 6
Step-by-step explanation:
1 in 6 chance of rolling a four in one roll
Multiply both sides by 10
10 in 60
The probability of rolling exactly 1 four is [tex]1.65\times10^{-8}[/tex].
Given that, a die is rolled 10 times.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favorable outcomes/Total number of outcomes
When throwing die once, we get
Probability of getting 4 = 1/6
Now, a die is rolled 10 times
= [tex](\frac{1}{6} )^{10}[/tex]
= 1/60466176
= [tex]1.65\times10^{-8}[/tex]
Hence, the probability of rolling exactly 1 four is [tex]1.65\times10^{-8}[/tex].

Mrs. Galicia sells online math and reading games. His revenue for each game (in dollars) is modeled by the given equations, where x is the number of days since the games went on sale.
Math Game: M(d)=2x^2+8x+2
Reading Game: R(d)=3x+5
Solve the system algebraically. After how many days is the revenue for each game the same? Show your work and explain your answer.
Graph this system to show the solutions. Label each axis appropriately.
Answer:
In the middle of a day
Step-by-step explanation:
1) Make it an actual equation
[tex]3x+5=2x^{2} +8x+2[/tex]
2) Cancel integers
[tex]3x + 3 = 2x^{2} + 8x[/tex]
3) Get rid of no exponent variables
[tex]0 = 2x^{2} + 5x - 3[/tex]
4) Factor :D

Joe runs 4 miles in 30 minutes. At the same rate, how many minutes would he take to run 10 miles?
Answer:
It would take him 75 minutes or one hour and 15 minutes
Step-by-step explanation:
[] We can set up a ratio and then cross multiply to find our answer
-> Let x be the minutes it takes him to run 10 miles
[] First, we will set up an equation
-> Keeping in mind that miles must be either on the top or the bottom, same goes for minutes, as units must be kept consistent.
[tex]\frac{4miles}{30minutes} =\frac{10miles}{x}[/tex]
[] Then, we will cross multiply
4x = 300
-> Divide both sides of the equation by 4
x = 75 minutes
Have a nice day!

Where's the expression?
Step-by-step explanation:
Without writing the equation (y-4)2 = 9(x-4) in the standard form, state whether the graph of this equation is a parabola,circle, ellipse, or hyperbola.
A. parabola
B. ellipse
C. hyperbola
D. circle
9514 1404 393
Answer:
A. parabola
Step-by-step explanation:
The curves ellipse, circle, and hyperbola are formed by a relation between the squares of the variables. Here, the y-variable is squared, but the x-variable is not. This equation describes a parabola.
_____
Additional comments
Its vertex is at (4, 4) and it is compressed horizontally by a factor of 9.
__
The hyperbola equation is the difference of squares; the circle and ellipse equations involve the sum of squares. If the variable coefficients are the same, then the sum of squares equation will describe a circle; an ellipse otherwise.

The graphs below have the same shape. What is the equation of the blue
graph?
G(= ?
F(x) = x2
G(x) =
O A. G(X) = (x - 3)2
O B. G(X) = (x + 3)2
O C. G(x) = x2 + 3
O D. G(x) = x2-3
Answer:
B. g(x) = (x +3)^2
Step-by-step explanation:
The graph of g(x) = f(x -h) will be a graph of f(x) shifted right h units. Here, the graph g(x) is the graph of f(x) shifted left 3 units. That means h = -3, and ...
g(x) = f(x -(-3)) = f(x +3)
g(x) = (x +3)^2

The vertex of g(x) is the point (-3, 0). You can use these (x, y) values in the offered choices, to see which equation will have that point on its graph.

explain how knowing that the sine of an angle is approximately 0.2588 enables you to find two possible values for the cosine of the angle. Find these values, and tell what information would be necessary to decide which of the two possible values is the correct cosine of the angle.
The required value is the angle theta and the value of the cosine of the angle is 0.9659
Given the expression of sine of an angle expressed as;
[tex]sin\theta = 0.2588[/tex]
For us to get the cosine of the angle, we need to get the value of theta first as shown:
[tex]\theta = sin^{-1}0.2588\\\theta = 14.99^0[/tex]
Next is to get the value of cos theta
[tex]cos \theta = cos 14.99 =0.9659[/tex]
The required value is the angle theta and the value of the cosine of the angle is 0.9659

What are the coordinates of the vertex of the graph of the function y=-3x2-12x +3?
Answer:
(-2, 15)
Step-by-step explanation:
y = -3x^2 - 12x + 3
a = -3
b = -12
c = 3
the formula for finding the x value of the vertex is -b/2a
so if we plug in the values into the equation we get
-(-12)/2(-3) = 12/-6 = -2
so our x value is -2
to find our y value we have to plug in -2 for every x we see in the original equation
so -3(-2)^2 - 12(-2) + 3 = -12 + 24 + 3 = 15
15 is our y value
so the vertex is (-2, 15)
