Answer:
∠p= 15° , ∠q = 108° , ∠r = 57° Is the Answer
Step-by-step explanation:
, (x -12)° + (5x-27)° + (2x + 3)° = 180°
or, 8x° -36° = 180°
Or x =
So, x = 27°
∴ ∠P = 27° -12° = 15°
∠q = (5 × 27)° -27° = 108°
∠r = (2 × 27)° + 3° = 57°
1. A plumber charges $50 for a house call in addition to $80
per hour worked. Which equation represents y, the total cost
for x, hours worked?
Answer:
Step-by-step explanation:
Since the plumber charges $50 regardless of how many hours he works, then the equation must be 50 + ....
Since the plumber charges $80 for each hour, then the equation will be y = 50 + 80x.

Answer: We all hate it when we are stuck! The slope is -1/2.
Step-by-step explanation: To find the slope, figure out the change of x divided by the change of y. The change of y is -1, and the change of x is 2. Therefore, the slope of the line is -1/2.
An airline claims that there is a 0.10 probability that a coach-class ticket holder who flies frequently will be upgraded to first class on any flight. This outcome is independent from flight to flight. Sam is a frequent flier who always purchases coach-class tickets.
For the following questions, pick the correct value rounded to the nearest hundredth.
What is the probability that Sam will be upgraded exactly 3 times in his next 20 flights?
What is the probability that Sam will be upgraded at most 4 times in his next 20 flights?
What is the probability that Sam’s first upgrade will occur on the third flight?
Answer:
b
Step-by-step explanation:
a) The probability that Sam will be upgraded exactly 3 times in his next 20 flights is 19.01 %
b) The probability that Sam will be upgraded at most 4 times in his next 20 flights is 95.68 %
c) The probability that Sam’s first upgrade will occur on the third flight is 0.0729
What is a Binomial Distribution?
The binomial distribution is a type of probability distribution that predicts the likelihood of obtaining one of two outcomes given a set of inputs. It summarizes the number of tries where each trial has the equal chance of producing the same result.
The formula for Binomial Distribution is given by
P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ
where
n = number of trials
x = number of successes
p = probability of getting a success in one trial
q = probability of getting a failure in one trial
q = 1 - p
Given data ,
Let the probability of getting a coach-class ticket be p
The value of p = 0.10
a)
The probability that Sam will be upgraded exactly 3 times in his next 20 flights
The number of trials = 20
The probability of success p = 0.10
The probability of failure q = 1 - p
The probability of failure q = 0.90
x = 3
Substituting the values in the equation , we get
P ( 3 ) = [ 20! / ( 17 )! 3! ] ( 0.10 )³ ( 0.90 )¹⁷
P ( 3 ) = 0.1901
P ( 3 ) = 19.01 %
b)
The probability that Sam will be upgraded at most 4 times in his next 20 flights
The number of trials = 20
The probability of success p = 0.10
The probability of failure q = 1 - p
The probability of failure q = 0.90
x ≤ 4
Substituting the values in the equation , we get
P ( x ≤ 4 ) = [ 20! / ( 16 )! 4! ] ( 0.10 )⁴ ( 0.90 )¹⁶
P ( x ≤ 4 ) = 0.9568
P ( x ≤ 4 ) = 95.68 %
c)
The probability that Sam’s first upgrade will occur on the third flight
A = ( 0.9 ) ( 0.9 ) ( 0.9 ) ( 0.1 )
A = 0.0729
A = 7.29 %
Hence , the solution is calculated by binomial distribution

3x - 5 = 7x + 11
Answer:
x=-4
Step-by-step explanation:
3x-5=7x+11 Add like terms
+5 +5
3x=7x+16 Do it again...
-7x -7x
-4x=16 Now divide
x=-4
Answer:
The answer is x=-4
Step-by-step explanation:
3x-5=7x+11
1) you have to move the number that has a variable with it onto one side(3x and +7x) and the numbers that do not have a variable move them onto the other side (-5 and +11),but if you move them you have to change the sign like the underlined numbers below
3x-7x=5+11
2) you have to subtract 3x and-7x which it equals -4x and then you have to add 5 and 11 which it equals 16
Equation now -4x=16
3) you have to divide -4x into -4x and also divide -4x into 16 which you will get x=-4

Cada dimensión será de 8,75 porque si la longitud es de 25 m de largo y el ancho es 10, si los sumamos y obtendremos 35. Así que 35 dividido entre 4 es 8,75

In a recent year, there were 15,900,000 high school
students in the United States. Suppose 250,000 of a
random sample of 500,000 high school students
during that year played on a sports team. Estimate
the total number of U.S. High school students that
played on a sports team that year.
Answer:
The total number of U.S. high school students that played on a sports team that year can be estimated to be 7,950,000.
Step-by-step explanation:
From the random sample, we can expect that [tex]\frac{250000}{500000}=\frac{1}{2}[/tex] of all students played on a sports team that year. So in the bigger sample of 15900000 high school students, we can expect [tex]15900000 \cdot \frac{1}{2} = 7950000[/tex] students to have played on a sports team that year.

Answer: (2, 19)
Step-by-step explanation:
There are three general ways to solve a system of equations:
- Substitution
- Elimination
- Augmented Matric
Since both given equations all have y isolated, substituting the value of y will be the most appropriate way here.
--------------------------------------------------------------------------------------------------------
Given
y=7x+5
y=x+17
Substitute y into the equations
7x+5=x+17
Subtract 17 on both sides
7x+5-17=x+17-17
7x-12=x
Subtract 7x on both sides
7x-12-7x=x-7x
-12=-6x
Divide -6 on both sides
-12/-6=-6x/-6
x=2
Substitute value into one of the equations
y=x+17
y=2+17
y=19

What is the measure of angle N?
=========================================================
Work Shown:
Apply the law of sines
sin(N)/MO = sin(O)/MN
sin(N)/18 = sin(17)/6
sin(N) = 18*sin(17)/6
sin(N) = 0.87711511416821 ................. which is approximate
N = arcsin(0.87711511416821)
N = 61.296295678111
N = 61 degrees approximately
----------------------
Notes:
Arcsine is the same as inverse sine. Your calculator is likely to have a button labeled [tex]\sin^{-1}[/tex] to indicate inverse sine.There are two solutions to sin(N) = 0.877; however, the other solution for N is larger than 90. This triangle your teacher is showing appears to be an acute triangle where every angle is less than 90 degrees. Technically two triangles are possible with these current given sides and angle.
