i need the answer to question 2, 3, and 4. question 1's answer is 9/28 & 32.1%.
Answers
The probability that a person wins the game is 32.1%
How to illustrate the probability?Based on the information given, the following can be depicted. It should be noted that there are 6 sides as well as 4 cards.
Therefore, the numbers on the dice i.e from 1 - 6 will be represented 4 times each. This gives a total of (4 × 6) = 24. There are also 4 cards. The total in sample space will now be:
= 24 + 4 = 28
The frequency table will be such that 28 or more has a relative frequency of 9. Therefore, the probability that a person wins the game will be:
= 9/28 = 32.1%
When you win 25% of the time, this illustrates that the number of products picked will be:
= 25% × 28
= 7 products.
The probability of participants achieving a winning score of 36 or higher in four consecutive attempts will be:
= 1/6⁴
= 1/1296

Limit of x approaches two from the left of f of x: 3. Limit of x approaches two from the right of f of x: - 1 (negative 1)
How to find the value of the function as x approaches infinity (+ve or -ve)?If limits exist, we can take limits of the function, where x tends to -∞ or ∞, and that limiting value will be the value the function will approach.
In order to find the limit as x approaches two from the left of f of x:
Lim x→2- f(x) = ?
According to the graph, when x approaches two from the left (x<2), the function approaches 3:
Lim x→2- f(x) = 3
IN order to find the limit as x approaches two from the right of f of x:
Lim x→2+ f(x) = ?
According to the graph, when x approaches two from the right (x>3), the function approaches -1:

The equation representing the cost in The Free Press is 12 + 5d.

The table of value for Free Press will be:
1st day = 12
2nd day = 17
3rd day = 22
4th day = 27
5th day = 32
The table of value for the Banner will be:
1st day = 8
2nd day = 16
3rd day = 24
4th day = 32
5th day = 40
The newspaper that will be used to run the advertisement for the first day is Free Press since it's cheaper.
The newspaper that will be used to run the advertisement for twelve days will be:
Free press = 12 + 5d

Answer:
y = (-3/2)x
Step-by-step explanation:
I am going to answer this question in slope-intercept form, which is y = mx + b (m is the slope, b is the y-intercept). The question already gives us the y-intercept, or the point at which the graph crosses the y-axis. It is (0, 0). Now, all we have to do is find the slope, which we can do using the following formula:
[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
In this formula, (x1, y1) and (x2, y2) are two points that are given to us [the first point is (0,0) and the second point is (2,-3). We can solve for the slope by plugging in:
[tex]m=\frac{-3-0}{2-0}=\frac{-3}{2}[/tex]
Now that we have m and b, we can plug into slope-intercept form to get our equation: y = (-3/2)x + 0 or y = (-3/2)x

5x + 2y = 3

Answers
The solution to the system of equations is x = -1 and y = 4
How to solve the system of equations?The system of equations is given as:
5x + 2y = 3
2x + 3y = 10
Multiply the first equation by 2 and the second by 5.
10x + 4y = 6
10x + 15y= 50
Subtract the above equations
10x - 10x + 4y - 15y = 6 - 50
This gives
-11y = -44
Divide by -11
y = 4
Substitute y = 4 in 5x + 2y = 3
5x + 2 * 4 = 3
This gives
5x + 8 = 3
Subtract 8 from both sides
5x = -5
Divide by 5
x = -1
Hence, the solution to the system of equations is x = -1 and y = 4

(2πr)
{note: "d" is diameter; "r" is radius; "π" is pi}
we know our diameter (d) to be 1.8
let's plug this into our cicumference formula! :

Step-by-step explanation:
Recall a probability: [tex]P=\frac{F}{T}[/tex] , where F is a number of favorable outcomes and T is a number of total outcomes.
The probability to get tail is [tex]\frac{1}{2}[/tex] as well as probability to get head.
The probability to choose number 7 of 8 numbers at total is equal to [tex]\frac{1}{8}[/tex].
Therefore, the probability to get number 7 and a tail is:
[tex]\frac{1}{8}\cdot \frac{1}{2}=\frac{1}{16}[/tex]
Prime numbers from 1 to 8 are: 2, 3, 5 and 7, so there are 4 numbers of 8 numbers in total, so the probability to get a prime number is [tex]\frac{4}{8}=\frac{1}{2}[/tex].
The second probability is equal to [tex]\frac{1}{2}\cdot \frac{1}{2}=\frac{1}{4}[/tex].
The numbers greater than 5 are: 6,7,8, so there are 3 numbers of 8 in total, so the probability to get a number greater than 5 is [tex]\frac{3}{8}[/tex].

Eric's: 1/x.Drew's: 2/x.Together: 1/6.Hence:
[tex]\frac{1}{x} + \frac{2}{x} = \frac{1}{6}[/tex]
[tex]\frac{3}{x} = \frac{1}{6}[/tex]
x = 18.
Hence, it will take 18 hours for Erick to build the garden box himself.

Answer:
(x + 4)(x - 2) = x · x
(option L)
Step-by-step explanation:
we know that area = length × width
So, can write out the lengths and widths that we know:
(note: I will use the square as the reference point, because we can simply say "x" for both of its side lengths--you'll see why this is easier later)
Rug A:
length = x
width = x
Rug B:
length: x + 4
(4 feet greater than rug A length)
width: x - 2
(2 feet less than rug A width)
we can now set these areas to be equal to each other:
(rug A) = (rug B)
(length · width of A) = (length · width of B)
(x · x) = [ (x + 4)(x - 2) ]
So, the equation:
(x + 4)(x - 2) = x · x
can be used to find x (the length in feet) of rug A
hope this helps!! have a lovely day :)
