Answer:

(a) Explained below.

(b) 0.0294

(c) 0.0173

(d) 0.09827

(e) 0.0452

Step-by-step explanation:

The complete question is:

According to an​ airline, flights on a certain route are on time 80​% of the time. Suppose 25 flights are randomly selected and the number of​ on-time flights is recorded.

​(a) Explain why this is a binomial experiment.

​(b) Find and interpret the probability that exactly 16 flights are on time. ​

(c) Find and interpret the probability that fewer than 16 flights are on time.

​(d) Find and interpret the probability that at least 16 flights are on time.

​(e) Find and interpret the probability that between 14 and ​16 flights, inclusive, are on time.

Solution:

(a)

Let the random variable X be defined as the number of​ on-time flights.

A Binomial experiment has the following properties:

If a random variable X is used in an experiment and the experiment has all the above mentioned properties, then the random variable X is known as a binomial random variable.

All of these properties can be confirmed for the random variable X.

Thus, this is a binomial experiment.

(b)

Compute the probability that exactly 16 flights are on time as follows:

[tex]P(X=16)={25\choose 16}(0.80)^{16}(0.20)^{25-16}[/tex]

        [tex]=2042975\times 0.0281475\times 0.000000512\\=0.029442375072\\\approx 0.0294[/tex]

Thus, the probability that exactly 16 flights are on time is 0.0294.

(c)

Compute the probability that fewer than 16 flights are on time as follows:

[tex]P(X<16)=\sum\limits^{15}_{x=0}{{25\choose x}(0.80)^{x}(0.20)^{25-x}}[/tex]

                 [tex]=0.0000+0.0000+....+0.011777\\=0.0173[/tex]

Thus, the probability that fewer than 16 flights are on time is 0.0173.

(d)

Compute the probability that at least 16 flights are on time as follows:

[tex]P(X\geq 16)=1-P(X<16)[/tex]

                 [tex]=1-0.0173\\=0.9827[/tex]

(e)

Compute the probability that between 14 and 16 ​flights, inclusive, are on time as follows:

[tex]P(14\leq X\leq 16)=\sum\limits^{16}_{x=14}{{25\choose x}(0.80)^{x}(0.20)^{25-x}}[/tex]

                          [tex]=0.004+0.0118+0.0294\\=0.0452[/tex]

Thus, the probability that between 14 and 16 ​flights, inclusive, are on time is 0.0452.

Your answer is:

The length is 17

Step-by-step explanation:

L= 11+w

P=46

perimeter formula:

W+W+L+L = P

W+W+(11+w)+(11+w) = P

First solve for W

4W+22 = 46

-22

4w=24

/4

w=6

Now plug in W for the L formula

l=11+w

L= 11+ 6

Answer:

The number of sections in Ancient history is 10, number of students in Medieval history is 22 and the number of students in Modern history is 13.

Step-by-step explanation:

[tex]x[/tex] = Number of sections in Ancient history

[tex]y[/tex] = Number of sections in Medieval history

[tex]z[/tex] = Number of sections in Modern history

The number of sections that are allowed is 45 so

[tex]x+y+z=45[/tex]

The number of students in each section is 4700 where 100 of them take ancient history 50 of them take medieval history and 200 take modern history so

[tex]100x+50y+200z=4700[/tex]

The number of professors is 58 where Ancient and Medieval History need only 1 professor per section and Modern History sections are taught by a team of 2 professors, so

[tex]x+y+2z=58[/tex]

Solving the first and last equations by subtracting them we get

[tex]-z=-13\\\Rightarrow z=13[/tex]

Substituting this value in the second equation and first equation we get

[tex]100x+50y+2600=4700\\\Rightarrow 100x+50y=2100\\\Rightarrow 2x+y=42[/tex]

[tex]x+y+13=45\\\Rightarrow x+y=32[/tex]

Solving these equations by subtracting them we get

[tex]x=10[/tex]

[tex]x+y=32\\\Rightarrow y=32-10=22[/tex]

So, [tex]x=10, y=22, z=13[/tex]

Hence, the number of sections in Ancient history is 10, number of students in Medieval history is 22 and the number of students in Modern history is 13.

Answer:

239

Step-by-step explanation:

Answer:

The answer is 279.

Step-by-step explanation:

The answer is 21.

First you Add both AB and BC which is 10x +14. Then you put 64 into the equation. 10x+14=64. Subtract 14 from 64 which is 50. So 10x=50. Then divide 10 from 50. which would be x=5. So if you plug it in. It would be 21.

Answer:

john has a 6 out of 10 chance of picking a pencil

Answer:

P=37.5%

Step-by-step explanation:

Frequentist Probability

The probability of an outcome is defined as the frequency of the number of times the outcome occurs relative to the number of times that it could have occurred.

The equation to calculate the probability is:

[tex]\displaystyle P=\frac{f}{n}[/tex]

Where f is the number of favorable cases and n is the total cases.

John has in a cup of his desk:

6 pencils

3 blue+5 black+2 red pens=10 pens

Picking one of the utensils from the cup can be done in 16 different ways. That is the total number of cases n=16

The outcome of taking a pencil can be done in 6 ways. That is the number of favorable cases. f=6.

The probability is:

[tex]\displaystyle P=\frac{6}{16}[/tex]

Simplifying:

[tex]\displaystyle P=\frac{3}{8}[/tex]

Or expressed as a percentage:

P=3/8*100%

P=37.5%

Answer:

I believe the answer is A

Step-by-step explanation:

I say it's A because the volume is double like it told us. Compared to the new box it's twice as long as the old boxes.

I hope this helps! ~~~~

The volume of the new box is 8 times the volume of the old box.

The correct answer is option (D).

The volume of a rectangular box with length L, width W and height H is,

V = L × W × H

Given: -

Let [tex]l,w,h[/tex] represents the length, width and height of the old rectangular boxes.

Let [tex]V_o[/tex] represents the volume of the old rectangular box.

⇒ [tex]V_o=l\times w \times h[/tex]

The length, width and height of the new boxes are all twice as long as those of the old boxes.

This means the length, width and height of the new boxes would be [tex]2l,2w,2h[/tex].

Let [tex]V_n[/tex] represents the volume of the new rectangular box.

So, the volume of the new rectangular box would be,

⇒ [tex]V_n=2l \times 2w \times 2h[/tex]

⇒ [tex]V_n = 8 \times l \times w \times h[/tex]

⇒ [tex]V_n=8 \times V_o[/tex]

This means, the volume of the new box is 8 times the volume of the old box.

Hence, option (D) is the correct answer.

Step-by-step explanation:

Answer:

-2.16

Step-by-step explanation: for all you edge people

Given:

The function is

[tex]r(x)=0.05(x^2+1)(x-6)[/tex]

where, function r gives the instantaneous growth rate of a fruit fly population x days after the start of an experiment.

To find:

Number of complex and real zeros.

Time intervals for which the population increased and population deceased.

Solution:

We have,

[tex]r(x)=0.05(x^2+1)(x-6)[/tex]

[tex]r(x)=0.05(x^3+x-6x^2-6)[/tex]

Here, degree of function x is 3. It means, the given function has 3 zeros.

From the given graph it is clear that, the graph of function r(x) intersect x-axis at once.

So, the given function r(x) has only one real root and other two real roots are complex.

Therefore, function r has 2 complex zeros and one real zero.

Before x=6, the graph of r(x) is below the x-axis and after that the graph of r(x) is above the x-axis.

Negative values of r(x) represents the decrease in population and positive value of r(x) represents the increase in population.

Therefore, based on instantaneous growth rate, the population decreased between 0 and 6 hours and the population increased after 6 hours.

Answer:

Function r has two complex zeros and one real zero. Based on the instantaneous growth rate, the population decreased between 0 and 6 hours and the population increased after 6 hours.

Answer:

Step-by-step explanation:

For example if you have a function f(x) = x - 1, then x = 1 is a zero of this function because using it as x gives 1 - 1 = 0. The Riemann Zeta function has some zeros that are easy to find which are of little interest but there are some other ones that are harder to find which is why the are called non-trivial.

Answer:

Kindly check explanation

Step-by-step explanation:

Given that :

Time taken to receive order = 2 minutes

Ingredient mixing and cake loading = 8 minutes

Baking time = 30 minutes

Number of cakes oven can hold at a time = 3

Cooling time = 1 hour = 60 minutes

Cake packing = 2 minutes

Billing customer = 3 minutes

a. What is the capacity of the process, and what is the bottleneck?

The capacity of the process:

Within an hour : two bakings can be done =(30 minutes * 2) = 60 minutes

Also oven can hold 3 cakes, so, 3 cakes can be baked at a time.

Hence, 3 cakes in 30 minutes ;

6 cakes in an hour;

Hence, capacity of the process is 6cakes per hour.

The bottleneck is the oven, because if the number of ovens were to be increased, the process capacity will increase, similarly, if one of the oven gets faulty, then the process capacity reduces further.

b. What is the throughput time for a typical cake?

The throughput time, is the summation of all the time taken to fully complete an order :

Receipt of order + mixing + baking + cooling + packing + billing

2 + 8 + 30 + 60 + 2 + 3 = 105 minutes

c. If on average five orders are taken per hour, how many cakes are there in the process (on average)?

(Throughput time / 60) * average number of order

(105/60) * 5

= 1.75 * 5

= 8.75
