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

Round 576.558 to the nearest tenths place
Answer:
576.6
(look at the number by the 10th place and round)
The value of 576.558 after rounding to the nearest tenth-place value is
576.6.
Option A is the correct answer.
What is place value?The place value of a number is given as:
Example:
1234.567
1 = thousand place value
2 = hundred place value
3 = tens place value
4 = ones place value
5 = tenths place value
6 = hundredths place value
7 = thousandths place value
We have,
576.558
The number in the tenth place is 5 bolded underscore.
576.558
Now,
The next value is 5 which is greater or equal to 5 so we will change the tenth place value 5 into 6.
If the next value was 4 or less we will keep the tenth place value 5 as 5.
Now,
The value of 576.558 after rounding to the nearest tenth-place value is
576.6.
Thus,
The value of 576.558 after rounding to the nearest tenth-place value is
576.6.
Option A is the correct answer.

Answer:
Step-by-step explanation:
center (-1, -2) , trough point ( 6, 4)
equation of the circle
r² = (x-h)²+(y-k)², where (h, k) are the coordinate of a circle so h=-1, k=-2
r² =(x+1)²+(y+2)², but (x, y ) are coordinates for any point on the circle so x=6 and y= 4
r² =(6+1)²+(4+2)²
r²= 7² +6²
r²= 85
so the equation is
(x+1)²+(y+2)²= 85
to find the points on the circle substitute in the equation x and y
(-10+1)²+(0+2)²= 85 ; 85=85 true
so the pint on the circle is (-10, 0)

Answer:
12°
Step-by-step explanation:
As we can see the triangles are congruent so
< F = < C ( being corresponding angles of congruent triangle)
< C = 29
Now
<A +<B + <C = 180° { being sum of angles of triangle }
5x + 1 + 90 + 29 = 180°
5x = 180° - 120°
5x = 60°
x = 12°
What is the domain of the function?
X+6
f(x)=(x-7)(x+5)
A all real numbers except 7
Ball real numbers except 5 and -7
Call real numbers except -5 and 7
D all real numbers
The required domain of the function is all real numbers except -5 and 7. Option C is correct.
Given that,
f(x) = (x + 6) /[(x-7)(x+5)]
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
here,
Given function,
f(x) = (x + 6) /[(x-7)(x+5)]
We can put any real number on the number line except 7 and -5, because at these value function gives the value as infinity.
Thus, the required domain of the function is all real numbers except -5 and 7. Option C is correct.

solve for x
Answer: x= 47 (If that says 3x+2)(the picture is a little blurry)
Step-by-step explanation:
Linear pairs of angles sum to 180.
37+(3x+2) =180
Combine like terms
39+ 3x = 180
Subtract 39 from both sides
3x = 141
Divide both sides by 3
x= 47

Answer:
Wendell only has $12 in nickels and dimes
Let Wendell have x dimes
If Wendell has 3 times as many nickels as dimes, how many dimes does he have?
Number of nickels = 3x
dime 10 c
nickel 5c
10x+5*3x = 1200 ( $12=1200 c)
25x = 1200
x= 48 number of dimes
