What’s the code for this puzzle, each answer represents a letter and explain is possible.

The probabilities for each case are:

There are 8 reservations for passengers that may go or not, such that the probability of arriving to the flight is P = 0.42, and the probability of not arriving is Q = 0.58

a) There will be overbooking if 7 or more passengers go to the flight, the probability that the 8 attend is:

P(8) = (0.42)^8

The probability that 7 attend is:

P(7) = 8*(0.42)^7*(0.58)

(where the factor 8 is because there are 8 permutations)

The total probability is:

P = P(8) + P(7) = 0.012

b) Will be empty seats if less than 6 people go.

The probability that exactly 6 of these people go to the flight is:

P(6) = (28)*(0.42)^6*(0.58)^2

Where there are 28 permutations, that is why we used that factor.

Then, the probability of having empty seats is:

P = 1 - P(6) - P(7) - P(8) = 0.937

Complete question :

Ryan is mowing lawns. It takes him an hour to mow one lawn. He has already spent 2 hours mowing lawns today. He can only mow today for a total of 5 hours at most. The given inequality can be used to find x, the number of lawns he can still mow today. Which statement is true? A. Ryan can mow no fewer than 7 additional lawns today. B. Ryan can mow no more than 3 additional lawns today. C. Ryan can mow no more than 7 additional lawns today. D. Ryan can mow no fewer than 3 additional lawns today.

Answer:

B. Ryan can mow no more than 3 additional lawns

Step-by-step explanation:

Given that :

Time taken to now 1 lawn = 1 hour = 60 minutes

Number of hours already spent mowing today = 2

He can mow at most 5 hours mowing today

Find the number of lawn x he can still mow today:

Since 1 lawn takes 1 hour to mow ;

Lawns mowed in 2 hours = 2 lawns

The most number of lawn he can mow today Given that he can only spent at most 5 hours mowing will be (5/1) = 5 lawns

Lawns mowed already + x ≤ 5

2 + x ≤ 5

x ≤ 5 - 2

x ≤ 3

Hence, Ryan can mow no more than 3 additional lawns.

=> 2x= 8

=> x = 4

Alice travelled 4km

Answer:

Option (C)

Step-by-step explanation:

Quadratic parent function has been given as,

f(x) = x²

If we reflect this function across the x-axis and vertically stretched by a scale factor of 'k',

g(x) = -kx²

This quadratic function passes through a point (1, -4),

g(1) = -k(1)²

-4 = -k

k = 4

Therefore, the new function after transformation will be,

g(x) = -4x²

Option (C) will be the correct option.  

The function g(x) is [tex]\rm g(x) = -4x^2\\[/tex].

Given that,

The function g(x) is a transformation of the quadratic parent function,

[tex]\rm f(x) = x^2[/tex]

We have to determine,

What function is g(x)?

According to the question,

The function f(x) is a transformation of the quadratic parent function,

[tex]\rm f(x) = x^2[/tex]

In the given figure the function g(x) reflect across the x-axis and is vertically stretched by a scale factor of 'k',

Then, The function g(x) is,

[tex]\rm g(x) = -kx^2[/tex]

Therefore,

The quadratic equation passes through the point (1,4),

[tex]\rm g(x) = -kx^2\\\\g(1) = -k(1)^2\\\\-4 = -k\\\\k= 4[/tex]

Therefore,

The function g(x) is,

[tex]\rm g(x) = -kx^2\\\\g(x) = -4x^2[/tex]

Hence, The required function g(x) is [tex]\rm g(x) = -4x^2\\[/tex].

Step-by-step explanation:

There are 52 weeks in a year. Divide 40,716/52 and you get $783 weekly.

The area of the sector which has a central angle of 5π/7 radians and a diameter of 5.6 in is 8.79 in².

The area of a circular sector is the total space occupied by it. The sector area is half of the product of the square of radius of the circle and the central angle.

It can be calculated as,

[tex]A_{sector}=\dfrac{d^2\theta}{8}[/tex]

Here, (d) is the diameter of the circle and (θ) is the central angle.

The central angle of the sector is 5π/7 radians and the diameter of the sector is 5.6 in.

Put the values in the above formula as,

[tex]A_{sector}=\dfrac{(5.6)^2\times5\pi}{8\times7}\\A_{sector}=\dfrac{(5.6)^2\times5\pi}{8\times7}\\A_{sector}=8.79 \rm \; in^2[/tex]

Hence, the area of the sector which has a central angle of 5π/7 radians and a diameter of 5.6 in is 8.79 in².

Answer:

Theoretical Probability: 33%

Experimental Probability: 25%

Which is greater?: Theoretical

Step-by-step explanation:

If two out of the six sections are labeled as 2, you'd have a theoretical probability of [tex]\frac{1}{3}[/tex] or 33% of winning.

Based on Stacy's experiment results, the pointer landed on a winning spin 30 out of the 120 times it was spun. This makes the experimental probability [tex]\frac{1}{4}[/tex] or 25% of winning.

In this scenario, the theoretical probability is greater than the experimental probability.
