Which relationships describe angles 1 and 2?
Select each correct answer.
O vertical angles
O complementary angles
O adjacent angles
O supplementary angles
Since the sum of angles 1 and 2 equals 90°, and they also share same side and same vertex, then, the relationships that describe both angles would be:
B. Complementary angles
C. Adjacent angles
What are Complementary Angles?Complementary angles are two angles whose sum equals 90 degrees (right angle).
Thus:
m∠1 + m∠2 + 90° = 180° (straight line angle)
m∠1 + m∠2 = 180° - 90°
m∠1 + m∠2 = 90°
Therefore, since the sum of angles 1 and 2 equals 90°, and they also share same side and same vertex, then, the relationships that describe both angles would be:
B. Complementary angles
C. Adjacent angles

Individual A has a circle of five close friends (B, C, D, E, and F). A has heard a certain rumor from outside the circle and has invited the five friends to a party to circulate the rumor. To begin, A selects one of the five at random and tells the rumor to the chosen individual. That individual then selects at random one of the four remaining individuals and repeats the rumor. Continuing, a new individual is selected from those not already having heard the rumor by the individual who has just heard it, until everyone has been told.
a. What is the probability that the rumor is repeated in the order B, C, D, E, and F?
b. What is the probability that F is the third person at the party to be told the rumor?
c. What is the probability that F is the last person to hear the rumor?
d. If at each stage the person who currently "has" the rumor does not know who has already heard it and selects the next recipient at random from all five possible individuals, what is the probability that F has still not heard the rumor after it has been told ten times at the party?
Answer:
Step-by-step explanation:
From the given information;
The possible number of ways to select these people in order B, C, D, E, and F is:
= 5 × 4 × 3 × 2 × 1
= 120
However, using the order B, C, D, E, and F; The probability that the rumor is repeated is:
= 1/120
= 0.0083
b)
If we make F the subject here by selecting it such that F has not been selected in the first and second draw;
Then:
The possible numbers of ways to select F as third = 4 × 3 × 2 × 1
= 24
Now;
the required probability of F is the third person: = 24/120
= 0.2
c)
Suppose F is selected as the last person to hear the rumor;
Then, the selection of F in the last row = 4 × 3 × 2 × 1
Recall that; the total possible number of ways to select the person is B, C, D,E, and F which is = 120
Then, the required probability of F as the last person to hear the rumor is:
= 24/120
= 0.2
d)
Here, the required probability of F since F has not heard the rumor after it has been told tren times is:
= 4¹⁰
Let's no forget that the total number of possible ways to select the persons using the above criteria is = 5¹⁰
Thus, the required probability of F = 4¹⁰/5¹⁰
= 0.1074

Can someone explain how to find
Answer:
155°
Step-by-step explanation:
<O=24
<P=2x+9
<N=180-(3x-28) (It’s the supplement of 3x-28)
Add them together to equal 180. (180 is the sum of the 3 interior angles of a triangle.)
24+2x+9+180-(3x-28)=180
24+2x+9+180-3x+28=180
-1x+241=180
-1x=-61
x=61
Now that we’ve solved for x, plug it back into <MNO
<MNO=3x-28=3(61)-28=183-28=155°
What is the length of the missing leg? If necessary, round to the nearest tenth.
I need help please
Answer:
b=8.28
Step-by-step explanation:
using pythagorean theorem:
a^2+b^2=c^2
5.62^2 +b^2= 10^2
31.36 + b^2 = 100
b^2= 68.64
b=8.28
The length of the missing leg will be;
⇒ b = 8.28 km
What is Pythagoras theorem?
The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.
Given that;
The triangle is shown in figure.
Here,
The length of perpendicular = 5.6 km
And, The length of hypotenuse = 10 km
Since, The triangle is a right triangle.
Hence, We can apply the Pythagoras theorem as;
⇒ Hypotenuse² = Base² + Perpendicular²
⇒ 10² = b² = 5.6²
⇒ 100 = b² + 31.36
⇒ b² = 100 - 31.36
⇒ b = √68.64
⇒ b = 8.28 km
Thus, The value of missing length = 8.28 km

Have a great day :)
Answer:
Hey:) Answer is below!
Step-by-step explanation:
Okay so the easiest thing I would do for each of these would be first to simplify them. So for the first one, 73 divided by 20, you could either do it on a calculator or just by long division. As a result, 73 divided by 20 is 3.65. The next two numbers, 2.638 and 3.16 are simplified, so you're good! Now lastly we got a mixed fraction. What you would do first, would be to multiply the left farmost number (in this case, 3) by the bottom number (which is 11). After that you would add the product of 3 and 11 (that would be 33) by 7. 33 plus 7 is 40. Finally, your number would be 40 over 11. Divide 40 by 11 (on a calculator or by long division) and you get 3.63. Now look at all your numbers, it should look like this: 3.65, 2.638, 3.16, 3.63
After that look at the number before the point (that would be 3 in the first one, 2 in the second, 3 in the third, and 3 in the fourth number). You see which one would be the smallest, and in this case it would be the second number, 2.638. So 2.638 goes first. Then look at the first number after the point for the last three numbers (that would be 6 for the first, 1 for the third, and 6 for the fourth). 1 in the third number is the smallest, so next goes 3.16. (This is the order for now: 2.638, 3.16)
Finally look at the second number after the point for the last two numbers (that would be 5 for the first and 3 for the fourth) 3 in the fourth number is the smallest, so next goes 3.63
As a result, you get this order from smallest to largest:
2.638,3.16, 3 7/11, 73/20
Good luck:))

Answer:
10152
Step-by-step explanation:
Common difference:
18-9=9
27-18=9
d=9
Explicit formula:
an = a1 +(n-1)d
a47 = 9+ (46)(9)
a47 = 423
Find sum: Sn = n(a1+an)/2
47(9+423)/2
47(423)/2 = 20304/2 = 10152

Suppose that a company wishes to predict sales volume based on the amount of advertising expenditures. The sales manager thinks that sales volume and advertising expenditures are modeled according to the following linear equation. Both sales volume and advertising expenditures are in thousands of dollars.
Estimated Sales Volume =46.63+0.47(Advertising Expenditures)
If the company has a target sales volume of $275,000, how much should the sales manager allocate for advertising in the budget?
Answer:
$485890
Step-by-step explanation:
Given
Estimated Sales Volume =46.63+0.47(Advertising Expenditures)
Required
Find the allocated amount for advertising expenditure when target sales is $275000
Represent the sales volume with V and The advertising expenditure with a.
So, the expression is:
[tex]V = 46.63 + 0.47A[/tex]
Since the expression is in thousands, substitute 275 for V
[tex]275 = 46.63 + 0.47A[/tex]
Collect Like Terms
[tex]275 - 46.63 = 0.47A[/tex]
[tex]228.37= 0.47A[/tex]
Make A the subject
[tex]A = \frac{228.37}{0.47}[/tex]
[tex]A = 485.89[/tex]
Hence, $485890 should be allocated for advertising

Suppose that IQ scores have a bell-shaped distribution with a mean of 104
104 and a standard deviation of 17.Using the empirical rule, what percentage of IQ scores are between 70 and 138?
Answer:
68%
Step-by-step explanation:
The empirical rule basically states that 68% of the data falls within one standard deviation from the mean, 95% of the data falls within two standard deviations from the mean, and 99.7% of the data falls within three standard deviations from the mean.
So to find the percentage of IQ scores between 70 and 138, you need to find how far each of these numbers is from the mean in terms of the standard deviation.
If you subtract the standard deviation from the mean, you receive 87, and if you add the standard deviation to the mean, you receive 121.
This means that both of these numbers are within one standard deviation from the mean meaning according to the empirical rule, that means 68% of the IQ scores are between 70 and 138.
good luck, i hope this helps :)
Answer:
99.7%
Step-by-step explanation:
According to the empirical rule, approximately 99.7% of data values lie within 3 standard deviations of the mean.
