A spinner has 8 equal sectors with different letters for each sector, as shown below:
A spinner with 8 equal sectors is shown. The sectors are labeled B, Y, G, P, O, V, M, and R.
Hamlet spins the spinner 13 times, and it stops at the letter R 9 times. If he spins the spinner a 14th time, what is the theoretical probability that this time it will stop at the letter R?
Answer:
The theoretical probability of obtaining letter 'r' at the 14th spin is:
1/8
Step-by-step explanation:
It is given that:
A spinner has 8 equal sectors with different letters for each sector.
The sectors are labeled b, y, g, p, o, v, m, and r.
Hamlet spins the spinner 13 times, and it stops at the letter r 9 times.
We are asked to find the theoretical probability that we will get letter r at the 14th spin.
The theoretical Probability is given as the ratio of number of favorable outcomes to the total number of outcomes.
Hence, the theoretical probability of obtaining letter 'r' at the 14th spin is:
( As there are a total of 8 outcomes( or 8 sectors) out of which there is only one sector which is red)
Hope this helped

Find the exact value of cos(a+b) if cos a=-1/3 and cos b=-1/4 if the terminal side if a lies in quadrant 3 and the terminal side of b lies in quadrant 2
Answer:
cos(a + b) = [tex]\frac{1}{12}(1-2\sqrt{30})[/tex]
Step-by-step explanation:
cos(a + b) = cos(a).cos(b) - sin(a).sin(b) [Identity]
cos(a) = [tex]-\frac{1}{3}[/tex]
cos(b) = [tex]-\frac{1}{4}[/tex]
Since, terminal side of angle 'a' lies in quadrant 3, sine of angle 'a' will be negative.
sin(a) = [tex]-\sqrt{1-(-\frac{1}{3})^2}[/tex] [Since, sin(a) = [tex]\sqrt{(1-\text{cos}^2a)}[/tex]]
= [tex]-\sqrt{\frac{8}{9}}[/tex]
= [tex]-\frac{2\sqrt{2}}{3}[/tex]
Similarly, terminal side of angle 'b' lies in quadrant 2, sine of angle 'b' will be negative.
sin(b) = [tex]-\sqrt{1-(-\frac{1}{4})^2}[/tex]
= [tex]-\sqrt{\frac{15}{16}}[/tex]
= [tex]-\frac{\sqrt{15}}{4}[/tex]
By substituting these values in the identity,
cos(a + b) = [tex](-\frac{1}{3})(-\frac{1}{4})-(-\frac{2\sqrt{2}}{3})(-\frac{\sqrt{15}}{4})[/tex]
= [tex]\frac{1}{12}-\frac{\sqrt{120}}{12}[/tex]
= [tex]\frac{1}{12}(1-\sqrt{120})[/tex]
= [tex]\frac{1}{12}(1-2\sqrt{30})[/tex]
Therefore, cos(a + b) = [tex]\frac{1}{12}(1-2\sqrt{30})[/tex]

opens down refers to the value of a being negative or positive. If it opens down, then a is negative.
shifting left or right refers to the value of h
shifting up or down refers to the value of k
For the first one: y = -a (x+8)² + k
second one: y = -a(x+h)² + 7

1. Is Andres triangle congruent to the one on the data card?
2. What other information could Andre have asked for to be sure the triangle he drew is congruent?
Answer:
1. Yes, both of the triangles are congruent to each other
2. Are the sides on the triangles from AB∠, BC∠, and CA∠ the same length as Andres triangles?
Step-by-step explanation:
Congruent means the same so number one is asking if the triangles are the same and yes the are because they have the same angles

Mary takes a flight from Arizona to Alaska. In Arizona, the temperature is 101°F, while in Alaska, the temperature is – 11°F. What is the difference between the temperatures in Arizona and Alaska?
Answer: How to find the difference is you have to subtract them. So if you subtract the difference would be 112.
So your answer is 112

7. On Monday, Jeremiah had a debt of $92.80 after buying a pair of Jordan's. Jeremiah was
paid $126.42 from his job at Home Depot on Tuesday. After depositing his check from
Home Depot, what is the amount, in dollars, in Jeremiah's bank account?
A $33.62
B. $219.22
C. $174.42
D. $42.22
Answer:
A $33.62
Step-by-step explanation:
To figure this out you have to take -92.80 and add 126.42 to get $33.62. Have a great day and LEAVE ME ALONE PLZ! <3
Answer:
-92.80+126.42=33.62
Step-by-step explanation
Since you owe $92.80 it would be a negative. So it would be like this.
126.42-92.80= 33.62
Or
-92.80+126.42=33.62

Connor has hired two painters to paint his house. The first painter charges $12 an hour and the second painter charges $11 an hour. It will take 15 hours of labor to paint the house. A. Wrote a polynomial to represent the total cost of the job if the first painter does x hours of work. B. Write a polynomial to represent the total cost of the job if the second painter does y hours of labor.
Answer:
Cost = cost of first painter + cost of second painter
= $12/hr * hours worked + $11 * hours worked
where x is the hours the first painter works
C(x) = 12 x + 11 ( 15 - x)
= 12 x + 165 - 11x
= x + 165
C(x,y) = 12 x + 11 y
where y = 15 - x because the total hours is 15

Step 2:
8 = - 6 + 2m Add 6m on both sides
Step 3:
14 = 2m Add 6 on both sides
Step 4:
m = 14 ÷ 2 Divide
Answer:
m = 7
Hope This Helps :)
Answer:
8+6=6m-4m( because when 6goes to first its+ be- and -6m goes right it be 6m it has own and rule).
