Quadrilateral ABCD is inscribed in a circle. Find the measure of each of the angles of the Quadrilateral. Show your work. ( Please do not recopy another students answers on Brainly Or Any Other Websites. You'll be reported if you do. (Will Mark Brainliest if answered correctly.
Answer:
Shown Below.Explanation:
opposite angles in a quadrilateral sum up to 180°
total interior angles in a quadrilateral is 360°
solve for x:
x - 2 + x + 2 = 180°
2x = 180°
x = 90°
solve for each angle:
1st
x + 2
90° + 2 = 92°
2nd
x - 2
90° - 2 = 88°
3rd
x - 10
90° - 10° = 80°
4th
360° - 80° - 88° - 92° = 100°
In the Country A legal system, a defendant is presumed innocent until proven guilty. Consider a nullhypothesis, H0, that the defendant is innocent, and an alternative hypothesis, H1, that the defendant is guilty. A jury has two possible decisions: Convict the defendant (i.e., reject the nullhypothesis) or do not convict the defendant (i.e., do not reject the null hypothesis). Explain the meaning of the risks of committing either a Type I or Type II error in this example.
Using error concepts, it is found that in this problem, a type I error would be finding an innocent person guilty, while a type II error would be finding a guilty person innocent.
What are Type I and Type II errors?Type I: Rejection of a true null hypothesis. The null hypothesis is true, but from a sample, you get enough evidence to reject.Type II: Non-rejection of a false null hypothesis. The null hypothesis is false, but from a sample, you do not get enough evidence to reject.Hence:
In this problem, a type I error would be finding an innocent person guilty, while a type II error would be finding a guilty person innocent.

How much did you deposit at the end of each month into an investment account to pay 6.5% compounded monthly to have $3 million when you retire and 37 years
Answer:
$272559.70
Step-by-step explanation:
So, let's start with what we know
This problem should be solved with the formula
A = P ( 1 + r/n)^nt
The variable A is the final amount
A = 3000000
This is the amount we want to achieve
The variable P is the principle, the amount of money you put in a bank to earn interest
We have to solve for this value
The variable r is the interest rate
r = 0.065
Note: I converted the percent to a decimal, so we can use it in the formula
The variable n is the amount of times interest is compounded
n = 12
The interest is compounded monthly in a year, so 12 times
The variable t is the amount of time you have to earn the interest
t = 37
So, let's solve for the value P with the values we know
3000000 = P ( 1 + 0.065/12)^(12x37)
3000000 = P(11.0067628047)
3000000 / 11.0067628047 = P(11.0067628047) / 11.0067628047
272559.702905 = P
P = 272559.70
Note: I rounded to the nearest cent, since there isn't a value of USD lower than 1 cent.
So, there you have it, a principle of 272559.70 will get you 3000000 in 37 years given that interest is compounded monthly at 6.5% interest rate

In a triangle ABC, the measure of angle B is 4 times the measure of angle A, and the measure of angle C is 17° less than 5 times the measure of angle A. Find the measure of the angles.
Answer:
A: 19.7º B: 78.8º C: 81.5º
Step-by-step explanation:
The trouble with problems like this is usually just getting started.
Hint: look at the descriptions of the angle measures and see if one of the angles is mentioned twice. It's angle A. Pick a variable for the measure of that angle, say a.
Angle B: "4 times the measure of angle A" becomes 4a
Angle C: "17 less than 5 times the measure of angle A" becomes 5a - 17
Now use the fact that relates all three angles: the sum of the measures of any triangle's angles is 180 degrees.
a + 4a + (5a - 17) = 180
Combine like terms.
10a - 17 = 180
Add 17.
10a = 197
Divide by 10.
a = 19.7 degrees
Try not to panic because the answer is not a whole number!
Plug this into the expressions for the other angles.
B: 4(19.7) = 78.8 degrees
C: 5(19.7) - 17 = 81.5 degrees
Check: 19.7 + 78.8 + 81.5 = 180

A troupe of 8 dancers is going to line up on stage. Of these dancers, 4 are wearing black and 4 are wearing red. A dancer wearing black must be in the first position and they must alternate between colors. In how many ways can the dancers line up?
Using the Fundamental Counting Theorem, it is found that there are 576 ways for the dancers to line up.
What is the Fundamental Counting Theorem?It is a theorem that states that if there are n things, each with [tex]n_1, n_2, \cdots, n_n[/tex] ways to be done, each thing independent of the other, the number of ways they can be done is:
[tex]N = n_1 \times n_2 \times \cdots \times n_n[/tex]
In this problem, considering the order:
Black - Red - Black - Red - Black - Red - Black - Red
The number of ways for each is given by:
4 - 4 - 3 - 3 - 2 - 2 - 1 - 2
Hence:
[tex]N = 4^2 \times 3^2 \times 2^2 = 576[/tex]
There are 576 ways for the dancers to line up.
