Suppose that you roll two dice. You will be paid $20 if you roll a double. You will not receive anything
for any other outcome. How much should you be willing to pay for the privilege of rolling the dice?
Please round your answer to the nearest cent.
Answers
There are 36 possible outcomes when rolling two dice, and only 1 of those outcomes results in a double. Therefore, the probability of rolling a double is 1/36, or approximately 0.028.
If you are willing to pay $20 to roll the dice, then you are effectively paying a premium of $20 for a probability of 0.028 of winning. This means that the expected value of rolling the dice is 0.028 * $20 = $0.56.
Therefore, you should be willing to pay up to $0.56 for the privilege of rolling the dice. Rounded to the nearest cent, this is $0.56.
Dominique throws a softball from the outfield. After 1 second, the ball is 15 feet high. After 4 seconds, the ball reaches its maximum height of 42 feet. After 7 seconds, it returns to a height of 15 feet.

Answers
The equation of the quadratic function that models the height of the ball h(t) at time t is h(t) = −3(t − 4)² + 42
How to determine the equation of the height function?From the question, we have the following parameters that can be used in our computation:
Height after 1 second = 15 feetHeight after 7 seconds = 15 feetMaximum height = 42 feetThe above parameters mean that
h(1) = 15
h(7) = 15
h max = 42
This also means that the leading coefficient of the function is negative
So, the possible equations from the options are
h(t) = −2(t − 4)² + 42
h(t) = −3(t − 4)² + 42
Calculate h(1) and h(7)
h(t) = −2(t − 4)² + 42
h(1) = −2(1 − 4)² + 42 = 24
h(7) = −2(7 − 4)² + 42 = 24
h(t) = −3(t − 4)² + 42
h(1) = −3(1 − 4)² + 42 = 15
h(7) = −3(7 − 4)² + 42 = 15
Hence, the function is h(t) = −3(t − 4)² + 42

Answers
The equation of certain hyperbola with center ( -2,0) is (x+ 2)²/25 - (y)²/ 9 = 1
According to the question,
Equation of hyperbola is given : (x-h)²/a² - (y-k)²/b² = 1
Center of hyperbola = (-2,0)
Focus = (-2√34 , 0)
vertex = (-5,0)
This hyperbola is from left to right
As center is (-2,0) means h = -2 and k = 0
Hyperbola are symmetric ,
Second focus = (-2√34 , 0)
Second vertex = ( 5,0)
Vertex are (a,b) => a = 5
Foci of general hyperbola are ( h ± ck)
=> ( h ± c, k) = (-2√34 , 0)
=> -2 ± c = -2√34
=> c = ± √34
Also , c^2 = a^2 + b^2
=> 34 = 25 + b^2

What is Taylor polynomial?
The Taylor series or Taylor expansion of a function in mathematics is the infinite sum of terms expressed in terms of the function's derivatives at one particular point. The function and the sum of its Taylor series are roughly equal for the majority of common functions at this point.
Given:
[tex]f(x) = e^x[/tex] centered at 2.
[tex]f(2) = e^2[/tex]
[tex]f'(x) = \frac{d}{dx}e^x = e^x , f'(2) = e^2\\f"(x) = \frac{d^2}{dx}(e^x) = e^x, f"(2) = e^2\\ f^3(x) = \frac{d^3}{dx}(e^x) = e^x, f^3(2) = e^2\\ f^4(x) = \frac{d^4}{dx}(e^x) = e^x, f^4(2) = e^2[/tex]
Therefore,
[tex]T_4(x) = f(2) + \frac{f'(2)(x-2)}{1!} + \frac{f"(2)(x-2)^2}{2!} + \frac{f^3(2)(x-2)^3}{3!} + \frac{f^4(2)(x-2)^4}{4!} \\T_4(x) = e^2 [1 + (x - 2) + \frac{(x-2)^2}{2}+\frac{(x-2)^3}{6}+ \frac{(x-2)^4}{24} \\ T_4(2.4) = e^2[1 + (2.4-2) + \frac{(2.4-2)^2}{2}+ \frac{(2.4-2)^3}{6}+\frac{(2.4-2)^4}{24}]\\ T_4(2.4) = 11.0225[/tex]

Answers
The statement "Δ ABD = Δ ACB by SSS" is true about the diagram.
The statement "Δ ABD = Δ ACB by SSS" is true about the diagram. SSS stands for Side-Side-Side, which is a congruence postulate stating that if three sides of one triangle are congruent to the corresponding sides of another triangle, then the triangles are congruent. In the given diagram, Δ ABD and Δ ACB are congruent because their corresponding sides AB, BD, and AC are equal in length.
This means that the triangles have the same shape and size, but they may be oriented differently. The SSS congruence allows us to conclude that all corresponding angles and other corresponding sides of the two triangles are also congruent.

We have to fill the blank.
We know that,
90% of the time, the real population mean will fall in the range of $1,500 and $2,100.
The genuine population mean will therefore most likely fall between $1,500 and $2,100, with a 90% probability.
So, the probability that it will fall outside of this range (i.e., be either less than $1,500 or beyond $2,100) is 100-90, or 10%.

The vertex (3, -16) is the maximum point on our quadratic equation.
Maximum and minimum values of the function:When we compare the given Quadratic function with the general form
ax² +bx +c,
If the value of a is positive then the Quadratic function will have a minimum value, and the graph of the function opens up.
If the value of a is negative then the Quadratic function will have a maximum value, and the graph of the function opens downwards.
Here we have
f(x) = -2(x - 5)(x-7)
f(x) = -2 [x²-7x - 5x + 35 ]
f(x) = -2 [x²-12x + 35 ]
f(x) = -2x² + 12x - 35
Compare f(x) with ax²+ bx + c
=> a = -2, b = 12, and c = - 35
Here,
a = -2 is a negative value then the function f(x) will have maximum value
And the graph of the function opens down.
The formula for the x coordinate of the vertex = -b/2a
The coordinate of x = -(12)/2(-2) = 3
Now substitute x = 3 in f(x) to find y-coordinate
=> f(3) = - 2(3)² +12(3) - 35
=> f(3) = -2(9) + 36 - 35
=> f(3) = - 16

The expressions that could represent how much snowfall Delphine had at her house in March will be:
1.4f
f + 0.4f
How to illustrate the expression?Expression simply refers to the mathematical statements which have at least two terms which are related by an operator and contain either numbers, variables, or both. Addition, subtraction, multiplication, and division are all possible mathematical operations.
Since Delphine's house had 40 percent more snowfall than in February. Delphine's house had f centimeters of snowfall in February.
The expression will be:
f + (40% × f)
f + 0.4f
= 1.4f

As part of the training for the cross-country team, you must run a total of 20 miles per week. You ran 5.6 miles in the first two days of the week. If you run the same amount each day for the remaining five days, how many miles must you run per day to complete the 20 miles?
Write and solve an equation to determine the number of miles, m, you must run per day.
5m + 2(5.6) = 20; m = 1.76
5m + 5.6 = 20; m = 2.88
5m − 5.6 = 20; m = 5.12
m + 5(5.6) = 20; m = 8

The equation to determine the number of miles, m, you must run per day is B. 5m + 5.6 = 20; m = 2.88
How to illustrate the equation?An equation is the statement that illustrates the variables given. In this case, two or more components are taken into consideration to describe the scenario. An equation is not the same as a mathematical expression. The equal (=) operator is always used to join two mathematical expressions in an equation.
In mathematics, an equation is a relationship between two expressions that is expressed as an equality on either side of the equal to sign. An equation would be 3y = 16, for instance. Equations can be categorized into one of the following three categories depending on their degree:
linear formulaquadratic formulaCubic problemIn this scenario, the person must run a total of 20 miles per week and ran 5.6 miles in the first two days of the week.
Let the number of miles for the remaining 5 days be m.
This will be:
5m + 5.6 = 20;
Solving for m = will give 2.88.
In conclusion, the correct option is B.

there is a line that includes the point (11,5) and has a slope of 8/11. what is its equation in slope intercept form?
Answers
Answer:
[tex]y=\frac{8}{11} x-3[/tex]
Step-by-step explanation:
Plug in the slope and point into the equation y=mx+b to solve for the y-value of the y-intercept. Plug in the x value for x, the y value for y, and the slope for m.
[tex]5=\frac{8}{11} (11)+b[/tex]
[tex]5=8+b[/tex]
[tex]-3=b[/tex]
After solving that, you can plug the slope and y-intercept back into the equation to solve for y.
[tex]y=\frac{8}{11} x+(-3)[/tex]
[tex]y=\frac{8}{11} x-3[/tex]
Answer:
Step-by-step explanation:
Slope-intercept form is y=mx+b where m is the slope and b is the y-intercept. We have all the information we need except for the y-intercept, so we can plug in our point to solve for the y-intercept.
------------------------------------Solving for y-intercept------------------------------------
Plugging in the point gives us [tex]5=8/11*11+b[/tex]. Simplifying this equation results in [tex]5=8+b[/tex]. To solve for b, we subtract 8 from both sides, giving us that [tex]b=-3[/tex]. We now have both the slope and the y-intercept, so our equation is y = 8/11x -3.
