Answer:
The value of S is 11.
Step-by-step explanation:
Okay, I found this answer due to that A = S to the power of 2 right? Then, A = 121 m2, so S2 is 121 square rooted, meaning what number is multiplied the same to get 121? 11. And if you multiply 11 by 11, you get 121.

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

The first step to solve the equation StartFraction x over 4 EndFraction minus three-fourths = 16 is shown below. StartFraction x over 4 EndFraction minus three-fourths + three-fourths = 16 + three-fourths Which property was applied in this step?
Answer:
Addition property of equality
Step-by-step explanation:
The given expression is :
[tex]\dfrac{x}{4}-\dfrac{3}{4}=16[/tex]
We need to find the first step to solve this expression.
For this, we add 3/4 to both sides of the equation i.e.
[tex]\dfrac{x}{4}-\dfrac{3}{4}+\dfrac{3}{4}=16+\dfrac{3}{4}\\\\\dfrac{x}{4}=16+\dfrac{3}{4}[/tex]
So, we have used the addition property of equality.
124 students played a sport in the fall, and 76 students played a sport in the spring. What was the percent decrease of the students who played sports in the spring? Round your answer to the nearest tenth of a percent.
Answer:
5.7%
Step-by-step explanation:
subtract 124-76.
then, you would divide 76 by 124 to get a weird number so multiply that by 100 to get this.
5.64516129.
then rounding to the nearest tenth would be 5.7.
so i think it would be 5.7%.

If the cost of 4 pears and 2 peaches equals $1.00 and the cost of 2 pears and 3 peaches equals $0.70 how much does each pear and each peach cost
Answer:
20 p per pear 10p per peach
Step-by-step explanation:
Hope this helps
Answer:
1 pear costs 20 cents. 1 peach costs 10 cents.
Step-by-step explanation:
x represents pears
y represents peaches
4x + 2y = 1
2x + 3y = 0.7
multiply the second equation by -2 to elimate the x variable
(2x +3y = 0.7) -2 = -4x - 6y = -1.4
add the new equation to the first original one:
4x + 2y = 1
-4x - 6y = -1.4
-4y = -0.4. divide both sides by -4, y = 0.10
plug in y = 10, solve algebraically and get x = 0.20
Lastly, check your work:
4(0.20) + 2(0.10) = 1
2(0.20) + 3(0.10) = 0.7

Answer:
8
Step-by-step explanation:
If the area is 32 and the formula for area of a triangle is base * height / 2, and you have base = 8 and height = x and area = 32, this would be:
8 * x / 2 = 32
Now, solve:
[tex]8x/2=32\\4x=32\\x=8[/tex]
Answer:
x=8
Step-by-step explanation:
Area is equal to half of the base times the height. We are told that the area is 32and the base is 8, so we can write this equation:
32=1/2(8)h
Multiply 1/2 by 8:
32=4h
Divide both sides by 4:
h=8
So now we know that x (the height) equals 8.

Pocahontas wants to buy a tennis racket that is 70% off. The original price is $156.33. What is amount of discount (nearest penny)?
What is the sale price (nearest penny) please show your work
1. You could plug this into the calculator as either 70% of 156.33 or 0.7 × 156.33, but either way you know the discount is going to be $109.43
2. We got the discount, so all you have to do is subtract it from the original. 156.33 - 109.43 = $46.90 which is the sale price! I hope this helps
Write an equivalent expression by distributing the "-−" sign outside the parentheses:
-(-1.5q+5r)+2
Answer:
1.5q - 5r = 2
Step-by-step explanation:
All you need to do here is negate each term inside the brackets, which allows you to get rid of the minus sign and the brackets.
-(-1.5q + 5r) = 2
is exactly the same as saying:
-1 × (-1.5q + 5r) = 2
And if we multiply each term in the brackets by negative one, we get:
(1.5q - 5r) = 2
And now the brackets can go, leaving you with:
1.5q - 5r = 2

A tree in leilas backyard has been growing for 3 1/5 years. It is 3/4 meters tall how many meters per year?
Answer:
The tree grew 15/64 meters per year.
Step-by-step explanation:
Given
Length of a tree = 3/4 metersTotal time taken by the tree to grow 3/4 taller = 3 1/5 or 16/5 yearsTo determine
Per year growth of the tree in meters
Per year growth of the tree in meters can be determined by dividing the total length of a tree i.e. 3/4 meters by the total time taken by the tree to get 3/4 taller.
Per year growth of tree = Total Length / Total time to grow
= 3/4 ÷ 16/5
= 3/4 × 5/16
= [3×5] / [4×16]
= 15/64 meters
Therefore, the tree grew 15/64 meters per year.
