Every morning, siblings Jack and Jill roll a regular six-sided die to determine who will get to ride in the front seat on the way to school. If the number is even, Jack gets to ride in the front. If the number is odd, Jill gets to ride in the front.
A. In the first 20 school days, how many times would you expect Jack to get to ride in the front seat?
B. In the first 100 school days, how many times would you expect Jill to get to ride in the front seat?
C. Which prediction (Jack or Jill's) do you think will be closer to the actual frequency? Use complete sentences to justify your answer.
Answer:
Step-by-step explanation:
A. It says he will get to sit in the front if the number is even
There are 6 sides, three of which are even numbers (2,4,6). So the probability of rolling an even number is 3/6 = 1/2.
Let's make p = 1/2
Jack will get his way half of the time, so we expect him to get the front seat half of the time
If we're talking about 20 days, then n = 20 and
n*p = 20*(1/2) = 20/2 = 10
meaning that Jack would, on average, get the front seat 10 times out of the 20 total.
B. Similar to A
n=100
The probability is still the same because rolling an odd number (1,3,5) is still going to happen 3/6 = 1/2 of the time.
so: n*p means 100 days*1/2 which is 100/2=50 days
Jill get to sit in the front 50 out of the 100 days.
C. For better accuracy, we can at least increase the number of trials so we have more data in able for better accuracy.
As Jill did 100 hundred, we think that she will get closer to the actual frequency. As larger the number of trials, the closer we'll get to the expected probability.
Answer:
A. Jack to get to ride in the front seat 10 times
B. In the first 100 school days, Jill will get to ride in the front seat 50 times.
C. As Jill did 100, I think that she will get closer to the actual frequency. As larger the number of trials, the closer we'll get to the expected probability.

The figure is the net for a rectangular prism.
What is the surface area of the rectangular prism represented by the net?
Surface area of rectangular prism is [tex]238\ mm^{2}[/tex] .
Step-by-step explanation:
We have net for a rectangular prism. Surface area of rectangular prism is given by:
Step 1:
We need to calculate area of material needed as shown in figure above, Let's first concentrate on vertical rectangle have width 11 mm and length ( 5 + 4 + 5 +4 ) mm = 18 mm. We know that ,
area of rectangle = length × width
⇒ [tex]area = length(width)\\area = 11(18)\\area = 198\ mm^{2}[/tex]
Step 2:
Now only two horizontal small rectangles are left with dimensions as length = 4 mm and width = 5 mm.
∴ area of rectangle = length × width
⇒ [tex]area = length(width)\\area = 4(5)\\area = 20\ mm^{2}[/tex]
Also there are Two rectangles , so
total area = [tex]2(area) = 2(20) = 40\ mm^{2}[/tex]
Step 3:
Adding area of step 1 and 2 we get : [tex]198\ mm^{2} + 40\ mm^{2} = 238\ mm^{2}[/tex]
∴ Surface area of rectangular prism is [tex]238\ mm^{2}[/tex].
what is 5/8 doubled as a fraction
Answer:
5/4
Step-by-step explanation:
doubled is basically multiplied by 2
so 5/8 *2
this would equal 5/8 *2/1
so we multiply the tops together and the bottoms together
so that would mean
10/8
we can divide both the top and bottom by 2 to simplify
this would be
5/4
This can be rewritten as
1 1/4 too.
The fraction 5/8 when doubled gives the fraction 5/4.
Given a fraction 5/8.
We have to find the fraction formed by doubling the fraction 5/8.
Doubling means multiplying by 2.
That is, some number is doubles or make it two times.
Here given fraction is 5/8.

Step-by-step explanation: Just substitute the 'x' in y=3x+1 with the number in the table (i.e 0, y=3*0+1= 1) and so forth
The table in the image is a table for the equation y = 3x + 1. It shows the values of y for different values of x.
Here is the table in text format:
x y
0 1
1 4
2 7
We can check that the values in the table are correct by substituting the values of x into the equation y = 3x + 1.
For example, if we substitute x = 0, we get y = 3(0) + 1 = 1, which is the value in the table.
The table can be used to graph the equation y = 3x + 1.
To do this, we plot the points (x, y) in the table on a coordinate plane.
The points will form a straight line.
Here is a graph of the equation y = 3x + 1:
graph of y = 3x + 1
graph of y = 3x + 1
The y-intercept of the graph is 1.
This means that the line passes through the point (0, 1).
The slope of the graph is 3.
This means that for every 1 unit that x increases, y increases by 3 units.
The graph can be used to solve for y for any given value of x.
For example, if we want to solve for y when x = 3, we can find the point on the graph where x = 3 and read off the corresponding value of y.
The point is (3, 10), so y = 10 when x = 3.

The volume of the tent is 46.67 ft³
Explanation:
Given that the rectangular base is 35 square feet.
The height of the pyramid is 4 feet.
We need to determine the volume of the tent.
The volume of the tent can be determined using the formula,
[tex]Volume=\frac{1}{3} Bh[/tex]
where B = 25 and h = 4
Substituting these values in the above formula, we get,
[tex]Volume = \frac{1}{3} (35\times 4)[/tex]
Multiplying the numerator, we get,
[tex]Volume= \frac{140}{3}[/tex]
Dividing, we get,
[tex]Volume =46.6667 \ ft^3[/tex]
Rounding off the value to the nearest hundredth, we have,
Volume = 46.67 ft³
Therefore, the volume of the tent is 46.67 ft³

what is the remainder when 3x^3-14x^2-14x+3 is divided by 3x + 5
Using the Remainder Theorem, the remainder when the polynomial 3x³-14x²-14x+3 is divided by 3x + 5 is found to be 7 after evaluating the dividend at the root of the divisor, which is -5/3.
The question asks for the remainder when the polynomial 3x³-14x²-14x+3 is divided by 3x + 5. To find the remainder, you can perform polynomial long division or use the Remainder Theorem. Since the divisor is linear, the Remainder Theorem states that the remainder is equal to the value of the dividend evaluated at the root of the divisor. The root of 3x + 5 is -5/3. Plugging this value into the dividend:
(3×(-5/3)³ - 14×(-5/3)²- 14×(-5/3) + 3).
After calculating, we find that the remainder is 7. Thus, when the given polynomial is divided by 3x + 5, the remainder is 7.

The cost, C(x),for manufacturing x units of certain product Is given byC(x)=x^2-20x+35, find the units manufactured at a cost of $5560
Answer:
No units
Step-by-step explanation:
The cost function is given by;
[tex]C(x)=x^2-20x+35[/tex]
To find the units manufactured at a cost of $5,560
We equate the C(x) to 5560 and solve for x.
[tex]x^2-20x+35 = 5560[/tex]
[tex]x^2-20x+35 - 5560 = 0[/tex]
[tex]x^2-20x - 5525= 0[/tex]
The discriminant of this equation is negative.
That is,

Hence the equation has no real roots.
This means no units can be produced at $5,560

Find the solution of the system of equations.
-3x-2y=36
3x-5y=6
The solution to the system of equations -3x-2y=36 and 3x-5y=6 is x = -8 and y = -6. This was achieved by adding the equations together to eliminate x, then solving for y, and substituting y into the first equation to solve for x.
Explanation:To find a solution to the system of equations, you can use the method of addition (also known as elimination). In this case, these equations are designed in a way that allows you to simply add them together. Having the equations: -3x-2y=36 and 3x-5y=6, if you add these two equations together, the x variable will cancel out, leading to: -2y - 5y = 36 + 6, simplifying this yields -7y = 42. Finally, to solve for y, you divide both sides by -7, yielding y = -6. Now that we have the value for y, we can substitute it into the first equation to solve for x: -3x - 2(-6) = 36 --> -3x + 12 = 36 --> -3x = 24. Dividing both sides by -3, we get
x = -8. Therefore, the solution to the system of equations is x = -8 and y = -6.
