The number of trees more than 10m tall but not more than 20m tall is 18 trees.

0 < h ≤ 5 = 5

height greater than 0m less than or equal to 5m

5 < h ≤ 10 = 9

height greater than 5m less than or equal to 10m

10 < h ≤ 15 = 13

height greater than 10m less than or equal to 15m

15 < h ≤ 20 = 5

height greater than 15m less than or equal to 20m

20 < h ≤ 25 = 1

height greater than 20m less than or equal to 25m

The number of trees that are more than 10m tall but not more than 20m tall are;

10 < h ≤ 15 = 13

15 < h ≤ 20 = 5

So,

13 + 5 = 18 trees

Therefore, the total number of trees which are 10m tall but not more than 20m tall is 18 trees.

The probability that the chosen day is a weekday given that no emails were received in the randomly selected interval is 10/17.

Given that, A random day is chosen (all days of the week are equally likely to be selected), and a random interval of length one hour is selected on the chosen day. It is observed that I did not receive any emails in that interval.

We need to find the probability that the chosen day is a weekday.

To solve this problem, we can use Bayes' theorem. Let A be the event that the chosen day is a weekday and B be the event that there are no emails received in the randomly selected interval.

Then the probability of A given B is given by:

P(A | B) = P(A) × P(B | A) / P(B)

where,

P(A) = Probability that the chosen day is a weekday = 5/7 (since there are 5 weekdays out of 7 days in a week)

P(B | A) = Probability that there are no emails received in the randomly selected interval given that the chosen day is a weekday = Probability that the interval falls within the non-working hours of the day = 16/24 = 2/3 (since there are 16 non-working hours out of 24 hours in a day)

P(B) = Probability that there are no emails received in the randomly selected interval = Probability that the interval falls within the non-working hours of any day in a week = (5/7) × (2/3) + (2/7) × (4/24) = 34/63 (since the probability of selecting a weekday is 5/7 and a weekend day is 2/7, and the probability of the interval falling within non-working hours is 2/3 for weekdays and 4/24 for weekends)

Therefore,

P(A | B) = (5/7) × (2/3) / (34/63) = 10/17

The probability that the chosen day is a weekday given that no emails were received in the randomly selected interval is 10/17. Therefore, the answer is 10/17.

Step-by-step explanation:

Right, okay, so this is a bit of a weird one. Let's go step by step.

"Today, 6 friends went out for lunch." = The number 6 is gonna be in our equation somewhere.

"Their total bill was $27.60" = so is the number 27.6

"They decided to split the bill equally" = 27.6 "split equally" (aka divided by) 6 friends is 4.6

"each paid with a $10 bill" = This is where it gets a lil weird. So, if they divided the bill among them, none of their amounts are gonna be anywhere near ten dollars. This is one of those questions that wouldn't really happen in real life. People would probably use fives instead, but whatever. So a number we'll be using for something is 10.

"How much money will each person get back?" = So we have to find the amount they all paid (10) minus the amount each one had to pay (4.6).

To put it all into a full equation...

10 - ( 27.6 / 6 )

Divide.

10 - 4.6

Subtract.

5.4

Put back into money form.

$5.40

Answer:

Each person will get back $5.40.

Answer:

if each paid a $10 bill, in total they paid $60 (cuz 10 x 6)

60 - 27.60 = 32.4

32.4/6 = 5.4 (divide the change between 6 people)

Each person will get $5.40 back.

Answer:

Mixed Number: 4 9/20
Decimal Form: 4.45

If this help please set brainliest.

Explanation:
To add these fractions, we first need to find a common denominator. 4 and 5 have a common multiple of 20, so we can express each fraction using a denominator of 20:

-4/5 = (-8)/20

5 1/4 = 21/4 = (215)/(45) = 105/20

Now we can add the fractions:

(-8)/20 + 105/20 = (105 - 8)/20 = 97/20

To express the result as a mixed number, we can divide 97 by 20 to get the integer part, which is 4 with a remainder of 17. The fraction part is 17/20, which can be simplified to 9/20 by dividing both the numerator and denominator by 8. The final result is:

4 9/20

This fraction can be simplified to 4.45 by dividing both the numerator and denominator by 5:

4 9/20 = (4*4 + 9)/(20/5) = (16 + 9)/4 = 25/4 = 6.25/1 = 6.25

So the final result is 4.45.

To find the value of y when x is 10, we can use the direct variation equation.  So, by using the direct variation equation we know that then x is 10, and the value of y is 70.

To find the value of y when x is 10, we can use the direct variation equation.

In this case, the equation would be y = kx, where k is the constant of variation.

To solve for k, we can use the given values. When x is 4, y is 28.

Plugging these values into the equation, we get \(28 = k * 4.\)
Simplifying this equation, we find that \(k = 7.\)

Now that we have the value of k, we can substitute it back into the equation y = kx.

When x = 10, the value of y is 70.

The given problem states that the value of y varies directly with x. This means that y and x are directly proportional, and we can represent this relationship using the equation y = kx, where k is the constant of variation.

To find the value of k, we can use the information given. We are told that when x = 4, y = 28. Plugging these values into the equation, we get 28 = k * 4. Solving for k, we divide both sides of the equation by 4, giving us k = 7.

Now that we know the value of k, we can find the value of y when x = 10. Plugging this value into the equation, we have y = 7 * 10, which simplifies to y = 70. Therefore, when x = 10, the value of y is 70.

In summary:
- The equation that represents the direct variation between y and x is y = kx.
- To find the value of k, we use the given values of x = 4 and y = 28, giving us k = 7.
- Substituting x = 10 into the equation, we find that y = 7 * 10 = 70.

The solutions that satisfy the zero product property are x = 4 and x = -6. These values make either factor equal to zero, resulting in the overall equation being true.

According to the zero product property, if the equation (x - 4)(x + 6) = 0 is true, it means that the product of the two factors (x - 4) and (x + 6) is equal to zero.

To satisfy this property, either one or both of the factors must be zero.

So, the statement that is true according to the zero product property is:

(x - 4) = 0 or (x + 6) = 0

This means that either (x - 4) equals zero or (x + 6) equals zero for the equation (x - 4)(x + 6) = 0 to be true.

Simplifying the two equations:

For (x - 4) = 0, adding 4 to both sides gives x = 4.

For (x + 6) = 0, subtracting 6 from both sides gives x = -6.

Therefore, the solutions that satisfy the zero product property are x = 4 and x = -6.

These values make either factor equal to zero, resulting in the overall equation being true.

In summary, according to the zero product property, the statement (x - 4) = 0 or (x + 6) = 0 is true, and the solutions that satisfy this property are x = 4 and x = -6.

⇒ T ⊂ I

⇒ 0 ∈ I

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We know that;

For ∅ ⊂ R;

A null set is a subset of R, and in fact every set in general. There are no elements in a null set thus making it automatically a subset of any non-empty set by definition.

Hence, We get;

⇒ ∅ ⊂ R

For 6 ∈ T;

Since T is the set of negative integers less than - 1.

Hence, 6 ∉ T

For {... , - 5, - 4, - 3, - 2} ⊆ T

The set on the left is exactly what is defined on the problem statement for T. (The bar below the subset symbol just means that the subset is not strict, therefore the set on the left can be equal to the set on the right. Without it, the statement would be false since a strict subset requires that the two sets should not be equal).

Hence, {... , - 5, - 4, - 3, - 2} ⊆ T

For T ⊂ I;

Clearly, T is the set of negative integers less than - 1.

Hence, It is subset of integers.

Hence,  T ⊂ I

For 0 ∈ Z;

Zero is indeed an integer thus it is an element of Z.

Hence, 0 ∈ Z

The population multiple regression model includes a response variable, a constant term, multiple explanatory variables, and an error term.

In multiple regression analysis, the population multiple regression model is a statistical model that represents the relationship between a response variable and multiple explanatory variables. The model assumes that the relationship between the response variable and the explanatory variables can be expressed as a linear combination of the variables, including a constant term. The constant term represents the intercept of the regression line and accounts for the average value of the response variable when all the explanatory variables are zero.

Additionally, the model includes an error term, also known as the residual term or the disturbance term. The error term captures the variability in the response variable that is not explained by the explanatory variables. It represents the random and unobservable factors that affect the response variable and are not accounted for in the model. The presence of the error term acknowledges that the relationship between the variables is not deterministic but contains some degree of uncertainty.

Develop similarity measures by applying the Jaccard index formula to the membership degrees of the fuzzy sets and use these measures for clustering objects based on their fuzzy characteristics.

The question is asking about new similarity measures of intuitionistic fuzzy sets based on the Jaccard index and their application to clustering.

To answer the question, first, let's understand what fuzzy sets and clustering are. Fuzzy sets are a generalization of classical sets where an element can have a degree of membership ranging between 0 and 1. Clustering, on the other hand, is a technique used to group similar objects together based on their characteristics.

Now, the question specifically mentions the Jaccard index as a basis for similarity measures. The Jaccard index is a measure of similarity between two sets, which is calculated as the ratio of the intersection of the sets to the union of the sets.

To develop new similarity measures for intuitionistic fuzzy sets based on the Jaccard index, you can apply the Jaccard index formula to compare the membership degrees of the elements in the fuzzy sets. The resulting similarity measure will provide a quantitative value indicating the degree of similarity between the sets.

These new similarity measures can then be applied to clustering. In clustering, the similarity measures between objects are used to determine the groupings. By utilizing the Jaccard index-based similarity measures for intuitionistic fuzzy sets, you can cluster objects based on their fuzzy characteristics and similarities.

In summary, the question asks about new similarity measures of intuitionistic fuzzy sets based on the Jaccard index and their application to clustering.
