Answer:
x=9
Therefore angles 7x-4 = 6x-4 = 59 degree
Step-by-step explanation:
7x-4 = 6x-4 Findings; alternate angles
Although any coefficient angles can be set = to each other.
7x-6x-4 = +5 Subtract 6x from both sides
x -4 = 5
x = 5+4 Add 4 to each side
x = 9
Find the angle degree
6(x) + 5 = 7(x) - 4 Plug 9 in to x
6(9) + 5 = 7 (9) - 4
54 + 5 = 63-4
59 = 59
x = 59 degree.

The graph of this function is a parabola which opens upward.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.
We have been given the following function:
g(x) = (x + 4)(x − 9)
The graph of this function is a parabola which opens upward and whose x-intercepts are:
x + 4 = 0
x = -4
x - 9= 0
x = 9
On the other hand, the y-intercept will be:
g(x) = (x + 4)(x − 9)
g(x) = (0 + 4) (0 − 9)
g(x) = -36
Hence, the graph of this parabola is attached below.

if angle poa is a right angle and if measure of angle coa is three times as large as measure angle poc.
The angles COA and POC are 22.5 and 67.5 degrees respectively as POA is a right angled triangle.
POA is a right angle so it is 90 degrees.
POC +COA = 90 .....(1)
Also, POC is 3 times as large as COA.
Let's take COA, "x"
POC = 3x
Substituting the values in equation (1) as follows:
x + 3x = 90
4x = 90
x= 22.5
Therefore,
COA = 22.5°
POC = 22.5*3 = 67.5°

According to data released by FiveThirty Eight (data drawn on Monday, August 17th, 2020), Donald Trump wins an Electoral College majority in the 2020 US Presidential Election in 10,997 simulations out of a total of 40,000 simulations.
(a) I am interested in the probability that Donald Trump wins any one simulation from the Five Thirty Eight model. Write the parameter of interest. Write and calculate the estimate of your parameter using mathematical notation.
(b) Construct a 95% confidence interval for the parameter from (a), show at least 4 significant digits. I highly recommend using R, and only rounding at the end.
(c) TRUE or FALSE:
According to the FiveThirty Eight model, there is a 95% probability that the true parameter of interest from
(a) lies within your interval from (b).
(d) TRUE or FALSE:
If I were to repeat samples of 40,000 from the Five Thirty Eight model, I expect 95% of my sample statistics from (a) to lie within your interval from (b).
(e) TRUE or FALSE:
If I were to repeat samples of 40,000 from the FiveThirty Eight model, I expect 95% of samples to lead to 95% confidence intervals that cover the true parameter of interest from (a).
(f) People often misinterpret the FiveThirty Eight model to say that our previous results suggest that Donald Trump "shouldn't" or "won't" win the election. Explain why this is not a correct interpretation. Suggest, calculate, and explain an alternative conclusion from the simulation results that is more intuitive and interpretable.
Answer:
a) P = 0.274925
b) required confidence interval = (0.2705589, 0.2793344)
c) FALSE
d) FALSE
e) TRUE
f) There is still probability that he would win. And it would be highly unusual if he wins assuming that the true population proportion is 0.274925.
Step-by-step explanation:
a)
PROBABILITY
since total number of simulations is 40,000 and and number of times Donald Trump wins an Electoral College majority in the 2020 US Presidential Election is 10,997
so the required Probability will be 10,997 divided by 40,000
P = 10997 / 40000 = 0.274925
b)
To get 95% confidence interval for the parameter in question a
(using R)
>prop.test(10997,40000)
OUTPUT
1 - Sample proportion test with continuity correction
data: 10997 out of 40000, null probability 0.5
x-squared = 8104.5, df = 1, p-value < 2.23-16
alternative hypothesis : true p ≠ 0.5
0.2705589 0.2793344
sample estimate
p
0.274925
∴ required confidence interval = (0.2705589, 0.2793344)
c)
FALSE
This is a wrong interpretation of a confidence interval. It indicates that there is 95% chance that the confidence interval you calculated contains the true proportion. This is because when you perform several times, 95% of those intervals would contain the true proportion but as the confidence intervals will vary so you can't say that the true proportion is in any interval with 95% probability.
d)
FALSE
Once again, this is a wrong interpretation of a confidence interval. The confidence interval tells us about the population parameter and not the sample statistic.
e)
TRUE
This is a correct interpretation of a confidence interval. It indicates that if we perform sampling with same sample size (40000) several times and calculate the 95% confidence interval of population proportion for each of them, then 95% of these confidence interval should contain the population parameter.
f)
The simulation results obtained doesn't always comply with the true population. Also, result of one simulation can't be taken for granted. We need several simulations to come to a conclusion. So, we can never ever guarantee based on a simulation result to say that Donald Trump 'Won't' or 'Shouldn't' win.
There is still probability that he would win. And it would be highly unusual if he wins assuming that the true population proportion is 0.274925.
If AB = 58, and BC = 46, find the length of the radius to the nearest tenth. Assume BC is tangent to Circle A.
Applying the Pythagorean theorem, the length of the radius is: 35.3 units.
How to Apply the Pythagorean Theorem?According to the Pythagorean theorem, the sum of the squares of the shorter sides of a right triangle equals the square of the longest side. For example, if a and b are two smaller legs of a right triangle, and c is the longest leg (hypotenuse) of the right triangle, then the Pythagorean theorem states that:
a² + b² = c².
Given the following parameters of the right triangle:
Triangle ABC is a right triangle with angle ACB as the right angle according to the tangent theorem since segment BC is tangent to Circle A
Segment AB = 58 (hypotenuse of the right triangle)
Segment BC = 46 (small leg of the right triangle)
Radius = AC (small leg of the right triangle)
Using the Pythagorean theorem, we have:
AC = √(AB² - BC²)
AC = √(58² - 46²)
AC = 35.3 units (to the nearest tenth).
Therefore, by using the Pythagorean theorem, the length of the radius of the circle, which is segment AC, to the nearest tenth is: 35.5 units.

https://brainly.com/question/28276953
Answer:
Step-by-step explanation
1. The total cost of the trip for all 16 families is Rs 2,16,352.
2. To find out how much each family paid, we need to divide the total cost by the number of families: Rs 2,16,352 ÷ 16.
3. When we do the division, we get the result: Rs 13,522.
Now let's check if this result is correct:
1. If each family paid Rs 13,522 for the trip, then the total cost for all 16 families would be: 16 × Rs 13,522 = Rs 2,16,352.
2. This is exactly the same as the total cost given in the problem statement.
So we have shown that each family paid **Rs 13,522** for the trip

them?
The required it will take 2 hours for the friends to put 7 km between them.
What are equation models?The equation model is defined as the model of the given situation in the form of an equation using variables and constants.
Let's call the number of hours it takes the friends to be "x". During that time, Rae will have traveled 2x km. And Dana will have traveled 3(x-1) km (since she left an hour later).
We can now set up an equation:
2x + 3(x-1) = 7
Expanding the second term:
2x + 3x - 3 = 7
Combining like terms:
5x - 3 = 7
Adding 3 to both sides:
5x = 10
Finally, dividing both sides by 5:
x = 2
So it will take 2 hours for the friends to put 7 km between them.

Is the given number a solution of the equation? Which value of d is a solution to the equation 13 – d = 8? 7 5 4 2
Answer:
d = 5 is a solution to the equation 13 - d = 8

We have to solve 13 - d = 8
Now,
13 - d = 8,
We add d on both sides,
13 - d + d = 8 + d
13 = 8 + d
we subtract 8 from both sides,
13 - 8 = 8 - 8 + d
5 = d
d = 5
Hence the answer is 5

Find the inverse of the following function. gx= 1/x-2
In order to find the inverse function of g(x) = 1/x - 2, we just need to switch g(x) for x and x for g-1(x), then we isolate the inverse function g-1(x):
\(\begin{gathered} g(x)=\frac{1}{x}-2 \\ x=\frac{1}{g^{-1}(x)}-2 \\ \frac{1}{g^{-1}(x)}=x+2 \\ g^{-1}(x)=\frac{1}{x+2} \end{gathered}\)So the inverse function is g-1(x) = 1/(x+2)
