The average rate of change of function is 10.2 inches per day

The equation to show the height of the flower is

g(n) = 10(1.02)n

Where g(n) is the height of the flower

n is the number of days

The value of n is from n = 1 to n = 5

The average rate of change of the function = f(5) - f(1) / 5 -1

Then,

f(5) = 10(1.02)(5)

= 51 inches

f(1) = 10(1.02)(1)

= 10.2 inches

Substitute the values in the equation

The average rate of change of function = 51 - 10.2 / 5 - 1

= 40.8 / 4

= 10.2 inches per day

Hence, the average rate of change of function is 10.2 inches per day

The probability of randomly selecting alphabet a is 1/26.

Simply put, the probability is the likelihood that something will occur. When we don't know how an event will turn out, we can discuss the likelihood or likelihood of several outcomes.

Statistics is the study of events that follow a probability distribution.

An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

So, the probability of the digit a:

We know that there are 26 digits in the alphabet.

Marcel selects 1 digit at random.

The probability of digit a will be:

The probability formula: P(E) = Favourable events/Total events

Put values and calculate:

P(E) = Favourable events/Total events

P(E) = 1/26

Therefore, the probability of randomly selecting alphabet a is 1/26.

The intervals in the solution set are those that make the inequalities 5(x – 2)(x + 4) > 0 true is (-∞, -4) U (2,∞).

Given that,

The inequality is 5(x – 2)(x + 4) > 0

We need to address the inequality and find a solution.

We know that,

Take the inequality

5(x – 2)(x + 4) = 0

Divide the equation both sides by 5

(x – 2)(x + 4) = 0

Now, we take each factor equal to 0

x-2 =0 , so x= 2

x+4 =0, so x= -4

Now we get

First interval (-∞,-4)

Second interval (-4,2)

Third interval (2,∞)

Now,

We take each interval with our inequality

First interval (-∞,-4), pick a number in this interval and check with our inequality.

Lets pick -5

5(-5 – 2)(-5 + 4) > 0

35>0 is true

Second interval (-4,2), pick a number in this interval and check with our inequality.

Lets pick 0

5(0– 2)(0 + 4) > 0

-40>0 is false

Third interval (2,∞), pick a number in this interval and check with our inequality.

Lets pick 3

5(3 – 2)(3 + 4) > 0

35>0 is true

The intervals in the solution set are those that make the inequalities true is (-∞, -4) U (2,∞).

a)The 95% confidence interval are

b))Yes, we can claim significant reduction in the rate of intrusion attempts

We have firewall change of 14 people.

We need to compute total sum before firewall change which can be done by

(56+47+49+37+38+60+50+43+59+50+56+54+58)/14

=657/14

=46.92

Now, similarly, after firewall change total sum is

(53+21+32+49+45+38+44+33+32+43+53+46+36+48+39+35+37+36+39+45)/20

=756/20

=37.8

Now the difference between average number of intrusion attempts before and after firewall change is

(46.92-37.8)

=9.12

Now, we need to make confidence interval to only 95% of this difference=

(95×9.12)/100

=44.196=44(approx)

It means our interval range varies from 0-44,44-88 with a difference of 44.

b)Yes, we can easily claim that rate of intrusion attempts decreases.

Before firewall change, we can see average number of intrusion attempt is =46.92

After firewall change, we can see average number of intrusion attempt is

37.8

So, we can see rate of intrusion decreases on increasing the number of blocked intrusions.

For computing z-value, we just need to take square root of the difference of average number of intrusions attempst

=>Z-value= √9.12=3.01

Using the z-table, we get that for the above z-value, corresponding p-value is 0.067

Hence, the interval range is 0-44,44-88 and b)Yes we can claim, p-value is 0.067.No, this assumption does not make a difference.

What is factorization?

Factorization in mathematics is the process of dividing a large number into smaller ones that, when multiplied together, give you the original number.

Here, we have

Given equation,

f(x) = 16x⁴ – 81 = 0

The difference of squares is used to solve this equation. There are three perfect squares: 16, x⁴, and 81. ( which means that it is a number multiplied by itself, 16 is 4 x4 for example).

We solve this equation by formula: (a² - b²) = (a - b)(a + b)

= 16x⁴ – 81 = 0

Now, we determine the square root of 16 which is 4, and of x⁴ which is x², and 81 which is 9.

Now we write the equation in the (a - b)(a + b) form :

In mathematics, interference is a phenomena that happens when two or more waves interact with one another. Depending on the waves' respective frequency  to reinforce or cancel. Interference can be constructive, where the waves combine to generate a bigger wave, or destructive, where the waves cancel each other out.

Answer:

No, it is not possible to create a triangle with these measurements.

Step-by-step explanation:

It must follow these rules:

a + b > c

b + c > a

a + c > b

The value of c for the statement P(Z>c) = 0.1379 in the standard normal distribution is 1.09.

Φ is symbol for cumulative distribution function (CDF) for standard normal distribution with mean equal to 0 and standard deviation equal to 1.

Z follow standard normal distribution. So,

Z ∼ N(0,1)

Since,

P(Z>c) = 0.1379

1 - P(Z≤c) = 0.1379

P(Z≤c) = 1 - 0.1379

P(Z≤c) = 0.8621

or

Φ(c) = 0.8621

Next, we know Φ(Z) is equal to P(Z≤z) with z∈R is CDF for N(0,1). So,

P(Z≤z) = 0.8621

From standard normal distribution table or z table, we get z = 1.09. So,

P(Z≤1.09) =  0.8621

Φ(1.09) = 0.8621

Since, Φ(c) = 0.8621. So, c = 1.09

Thus, the value of c is 1.09 for statement P(Z>c) in standard normal distribution is equal to 0.1379.

A sample is a specific group of people from whom we collect data.

Stratified Sampling:

In statistics, a simple random sample is a subset of people selected from a larger set in which subsets of people are randomly selected, all with equal probability. This is the process of randomly selecting samples.

In stratified sampling, a population is divided into subpopulations that may differ in important ways. By ensuring that each subgroup is well represented in your sample, you can draw more precise conclusions.

To use this sampling method, divide the population into subgroups (called strata) based on relevant characteristics (gender identity, age group, income class, occupational role, etc.).

Calculate how many people to sample from each subgroup based on the total population percentage. Then use random or systematic sampling to select one sample from each subgroup.
