The slope of the line is 2.
We are given a graph with coordinate axes, namely, the x-axis and the y-axis.The intersection of the coordinate axes is called the origin with coordinates (0, 0).The line is drawn in blue.The line passes through two dots, whose coordinates can be found using the graph.The coordinates of the points are (1, 1) and (-1, -3).The slope "m" of a line passing through points (x1, y1) and (x2, y2) is calculated as :m = (y2-y1)/(x2-x1)The slope of the line shown in the graph is :m = (-3-1)/(-1-1)m = -4/-2m = 2Thus, the slope of the line is 2.To learn more about slope, visit :

The answer in simplest form is [tex]20\frac{30}{11}[/tex] .
What is fraction in simplest form?When the numerator (top) and denominator (bottom) of the fraction do not have any common factors, the fraction is said to be in its simplest form. When the top and bottom of a fraction are whole numbers that are coprime to one another, the fraction is said to be in its simplest form.Any fraction can be easily found in its simplest form. By dividing both the numerator and denominator by the greatest common factor that entirely divides them, we need to simplify the fraction's numerator and denominator. Both the numerator and the denominator should still be whole numbers after division. Reducing fractions is another name for this process of simplifying fractions.Given fraction is [tex]5*4\frac{6}{11}[/tex].
So we convert the mixed fraction into an improper fraction to calculate further.
[tex]4\frac{6}{11} =\frac{50}{11}[/tex]
Next, we calculate the above fraction given in the question
[tex]5*\frac{50}{11}[/tex] = [tex]\frac{250}{11}[/tex]
So now we convert obtained improper fraction to mixed fraction which is its simplest form,
[tex]\frac{250}{11} = 20\frac{30}{11}[/tex]

every tuesday joe has a beer with 2 friends. they each have a unique token and every tuesday, they each put their token in a hat and ask the bartender to draw one token out. the person whose token is drawn pays the tab. over the next 3 weeks, what is the chance that joe has to pay the tab at least once? fill in the answer as a percent carried to one decimal place, but without the percent sign.
Answers
0.384 is the chance that joe has to pay the tab at least once by probability.
What is a math illustration of probability?
The likelihood or chance of an event happening is known as probability. For instance, there is only one way to receive a head and there are a total of two possible outcomes, hence the probability of flipping a coin and getting heads is 1 in 2. (a head or tail). P(heads) = 12 is what we write.The four most popular approaches to probability are classical, empirical, subjective, and axiomatic.Every tuesday Joe has beer with 4 friends .
Each have unique token , and the person whose token is drawn pays the tab.
Since , there are Joe and 4 friends , so we have total of 5 persons.
Now, probability that Joe token will be drawn is = 1 / 5 { 1 (Favourable Outcome) \small / 5 (Total Outcome) }
i.e there is 1/5 = 0.20 probability that Joe token will be drawn and he will pay the tab.
Over the next 3 weeks , we need to find the change that Joe pays the tab exactly one time.
Here we have n = 3 ( weeks ) , and probability of success is p = 0.20
i.e probability that Joe will pay tab (Success) is p = 0.20 and probability that Joe will not pay tab ( failure ) is 1-p = 0.80.
So we can model it by binomial distribution , as we have only two outcome which are i) Joe pays the tab , ii) Joe do not pay tab.
X ~ B(n=3 , p =0.20)
We need to find P(X=1) , i.e exactly one time Joe pays the tab .
Since, we have approximate that X follows binomial distribution , so we have
f(x) = P(X=x) = \small \binom{n}{x}p^x(1-p)^{n-x}
Hence
P(X=1) = ( n 1 ) p¹ ( 1 - p)ⁿ⁻¹
= ( 3 1 ) 0.2¹ ( 1 - 0.2)³⁻¹
= 3 * 0.2 * 0.8²
= 0.384

The graph of y = 2x^2 - 8x + 7 is identical to the graph of y = a(x-h)^2 + k$ for some real numbers $a, h, k$.
What is the value of $k$?
Answers
The form:
y = a(x-h)^2 + k
Is the vertex form of the quadratic equation, by finding the vertex, we conclude that k = -1.
How to get the value of k?For any quadratic equation of the form:
y = a*x^2 + b*x + c
With a vertex (h, k), we can rewrite the equation as:
y = a*(x - h)^2 + k
And the value h of the vertex is given by:
h = -b/(2a)
In this case, the quadratic equation is:
y = 2x^2 - 8x + 7
Then the value h of the vertex is:
h = -(-8)/(2*2) = 2
Evaluating the quadratic equation in x = 2 we will get the value of k, so we have.
y = 2*(2)^2 - 8*2 + 7 = -1
Then the vertex is (2, -1), which means that the value of K is -1.

Assume that when human resource managers are randomly selected, % say job applicants should follow up within two weeks. If human resource managers are randomly selected, find the probability that exactly of them say job applicants should follow up within two weeks.
Answers
The probability that exactly of them say job applicants should follow up within two weeks is 0.2291
Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.
The binary probability distribution can be used to model the given issue.
Assume that X is a binomial random variable with the values n and p, where n is the total number of human resource managers that were randomly chosen and p is the likelihood that the chosen manager will advise job seekers to follow up within two weeks.
total human resource managers were chosen at random, n = 9
The likelihood that the chosen human resources manager will advise job seekers to follow up within two weeks = 57 (0.57)
As we are aware, the probability of "m" successes for a binomial distribution is calculated as -
[tex]P(X=m) = ^{n}C_{m} (p)^{m}(1-p)^{n-m} = \frac{n!}{m! (n-m)!}(p)^{m}(1-p)^{n-m}[/tex]
Using the aforementioned data, we can now calculate the likelihood that exactly 6 of the 9 applications who were chosen will advise job seekers to follow up within two weeks as follows:
n = 9
p = 0.57
m = 6
[tex]P(X=m) = \frac{n!}{m! (n-m)!}(p)^{m}(1-p)^{n-m}[/tex]
[tex]P(X=6) = \frac{9!}{6! (9-6)!}(0.57)^{6}(1-0.57)^{9-6}[/tex]
[tex]= \frac{9!}{6! 3!} (0.57)^{6} (0.43)^{3}[/tex] = 0.2291 (rounded to 4 decimal places)
Therefore, the probability that exactly of them say job applicants should follow up within two weeks is 0.2291

six tickets to a movie cost $76.50. What constant of proportionality relates the number of tickets and total cost?
Answers
The constant of proportionality is 12.75
The constant of proportionality is the ratio of the constant values of two proportional quantities.
Two changing values are said to be in proportion when either their ratio or product results in a constant. The proportionality constant's value is determined by the Direct Variation and Inverse Variation types of proportions between the two supplied values.The direct proportionality equation, y = kx, shows that when x increases, y increases at the same rate. As an illustration, y x stands for the cost per item(y), which is inversely related to the quantity of items(x) bought.The indirect proportionality equation, y = k/x, shows that when y increases, x decreases, and vice versa.The direct variation is given by y = k x where k is the constant of proportionality.
Now the cost of 6 tickets is $76.50
76.50 = k × 6
or, k = 12.75
Therefore the constant of proportionality is 12.75

Answer:
x= 8
Step-by-step explanation:
So this is not as hard as it looks
the aim of this question is to work out what x is
so we need to find x on it's own
therefore we must work on removing the number on the right and to do this we first of all have to get a number that is divisible by 3.
now this is not always the case but I think you can tell from this question that it is obvious.
so what you do first is reverse the -1.5 into a positive and if it was the other way round so positive to a negative
so we do 1.5 + 22.5 which equals to 24
now this is simple division so 24 ÷ 3 = 8

Step-by-step explanation:
first you need to find common denominators. To find it, you would multiply the denominator of the 1 2/3 and the 2 3/8.8*3=24, which means the denominator is 24. For 1 2/3, we multiplied 3*8 so we also have to do it for 2. The new equation is x+1 16/24=2 3/8. But remember, we still have to multiply 8*3, which means we have to multiply 3*3 too.
New equation:x+1 16/24=2 9/24

where:
y = The height of the penny (in feet).x = The time since the penny was dropped (in seconds).The penny reaches the ground when the height is zero, so when y = 0.
Substitute y = 0 into the given equation and solve for x:
