The set of integers is a Pythagorean triple are option (A) 10, 24, 25 and (D) 6, 8, 10

A Pythagorean triple is a set of three positive integers a, b, and c, such that a^2 + b^2 = c^2, which represents the sides of a right triangle.

Let's check each set of integers

A. 10^2 + 24^2 = 100 + 576 = 676 = 25^2. Therefore, (10, 24, 25) is a Pythagorean triple.

B. 9^2 + 12^2 = 81 + 144 = 225 = 15^2. Therefore, (9, 12, 15) is a Pythagorean triple. However, the set given is (9, 12, 21), which is not a Pythagorean triple.

C. 8^2 + 15^2 = 64 + 225 = 289 = 17^2. Therefore, (8, 15, 17) is a Pythagorean triple. However, the set given is (8, 15, 23), which is not a Pythagorean triple.

D. 6^2 + 8^2 = 36 + 64 = 100 = 10^2. Therefore, the set of integers (6, 8, 10) is a Pythagorean triple.

Therefore, the correct options are (A) 10, 24, 25 and (D) 6, 8, 10

We know that the thickness of the lake decreases at a rate of 0.2 meters per week, so we can write:S(t)=-0.2t+4.

What is  thickness ?

Think of the thick sheet of ice you need to properly skate on a lake. Thick items are large, substantial, or unquestionably not thin. Thick may also signify "dense," as in your sister's thick, curly hair or a thick chocolate milkshake. The smallest of an object's three descriptive dimensions—height, breadth, and length—is referred to as thickness. If the volume and the area of one side of a rectangular prism are known, you may use those two quantities to determine the thickness of the prism.

We also know that after 7 weeks, the sheet is only 2.42 meters thick, which means we can write:

S(7)=2.42

S(7)=-0.2*7+X

S(7)=-1.4+X

2.42=-1.4+X

X=3.82

So, the function is: S(t)=--0.2*t+3.82

Step-by-step explanation:

using the quadratic formula (-b+-√(b^2-4ac))/2a

a=-16 b=119 c=57

x=-0.451

and

x=7.889

time cant be negative so use the positive x

Time required for the rocket to hit the ground would be 7.9 s.

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is  ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

We are given the quadratic equation as;

-16x² + 119x + 57 = 0

By using the quadratic formula,

x = [-b ± √b² - 4ac]/2a

Here, a = -16, b = 119 and c = 57

b² - 4ac = (119 )² - 4(-16)(57)

= 14161 + 3648

= 17809

So, x = [-(119) ± √17809]/ 16(2)

= (-119 ± 133.4)/32

Therefore, the time is 7.9 s.

Answer:

x = 15, y = 50

Step-by-step explanation:

8x + 12 and 2x + 18 are same- side interior angles and sum to 180° , then

2x + 18 + 8x + 12 = 180

10x + 30 = 180 ( subtract 30 from both sides )

10x = 150 ( divide both sides by 10 )

x = 15

Then

8x + 12 = 8(15) + 12 = 120 + 12 = 132

3y - 18 and 8x + 12 are vertical angles and are congruent, so

3y - 18 = 132 ( add 18 to both sides )

3y = 150 ( divide both sides by 3 )

y = 50

X = 15

Y = 50

(8x+12) + (2x+18) = 180 -- combine like terms

10x + 30 = 180 -- subtract 30 from both sides

-30 -30

10x = 150 -- divide by 10 on both sides

x = 15

and for y:

plug x into (8x+12)

8(15) + 12 = 3y - 18

120 + 12 = 3y - 18

132 = 3y - 18 -- add 18 to both sides

150 = 3y -- divide both sides by 3

y = 50

the main answer is that the mean value of the activity time is 21.67. This is calculated using the formula (optimistic + 4 * most likely + pessimistic) / 6.

To find the mean value of the activity time, we can use the three estimates provided: optimistic, most likely, and pessimistic time.

1. The optimistic time is the shortest possible time for completing the activity, which is 11 units.
2. The most likely time is the time that is most likely to be taken to complete the activity, which is 21 units.
3. The pessimistic time is the longest possible time for completing the activity, which is 35 units.

To calculate the mean value, we can use the following formula:
Mean value = (optimistic + 4 * most likely + pessimistic) / 6

Substituting the given values, we get:
Mean value = (11 + 4 * 21 + 35) / 6

Calculating the numerator first:
11 + 4 * 21 + 35 = 11 + 84 + 35 = 130

Now, we can calculate the mean value:
Mean value = 130 / 6

Dividing 130 by 6, we get:
Mean value = 21.67 (rounded to two decimal places)

Therefore, the mean value of the activity time is 21.67.

You can infer causality from a correlational result, but only when the r value is greater than:

C. 1

Causality refers to a situation in which one event causes another. When there is a correlation between two variables, it means that they tend to move in the same direction.

However, this does not necessarily mean that one event causes the other. In order for a correlation to indicate causality, the correlation coefficient (r) must be greater than 1. If the correlation coefficient is below 1, then there is not enough evidence to suggest that one event causes the other.

In addition, there are other factors that need to be considered when assessing causality from a correlational result.

For example, the strength of the relationship between the variables, the direction of the relationship, and the consistency of the results over time. It is also important to consider the context in which the research was conducted, as this may have an effect on the results.

Step-by-step explanation:

Approximately 5.48% of the trees have a circumference smaller than 22 inches given that the mean is 30 inches.

To find the percentage of trees with a circumference smaller than 22 inches, we can use the concept of z-scores.

A z-score measures how many standard deviations a value is from the mean.

First, we calculate the z-score for the 22-inch circumference sapling using the formula:

z = (x - mean) / SD.

In this case, the mean is 30 inches and the standard deviation (SD) is 5 inches.

Plugging in the values, we get z = (22 - 30) / 5

= -1.6.

Next, we find the area under the normal curve to the left of the z-score using a z-table or a calculator.

A z-score of -1.6 corresponds to an area of approximately 0.0548.

To convert this to a percentage, we multiply by 100:

0.0548 * 100 = 5.48%.

Therefore, approximately 5.48% of the trees have a circumference smaller than 22 inches.

A van can carry 12 students, and a bus can carry 36 students. The senior class at NAHS rented and filled 6 vans and 12 buses with 504 students.

To determine how many students a van can carry and how many students a bus can carry, we can use a system of equations based on the given information.

Let's assume that the number of students a van can carry is "v" and the number of students a bus can carry is "b".

According to the information provided:

The senior class at NAHS rented and filled 6 vans and 12 buses with a total of 504 students.

The senior class at FCHS rented and filled 2 vans and 5 buses with a total of 204 students.

Based on these conditions, we can form the following equations:

Equation 1: 6v + 12b = 504

Equation 2: 2v + 5b = 204

We now have a system of two equations with two unknowns (v and b). We can solve this system to find the values of v and b.

Let's solve the system using any preferred method, such as substitution or elimination.

Multiplying Equation 2 by 6, we get:

12v + 30b = 1224

Subtracting this equation from Equation 1, we can eliminate v:

6v + 12b - (12v + 30b) = 504 - 1224

-6v - 18b = -720

Simplifying this equation, we get:

-6v - 18b = -720

Dividing this equation by -6, we obtain:

v + 3b = 120

Now we have a new equation:

v + 3b = 120 -------------- Equation 3

We can now solve Equations 2 and 3 as a new system of equations.

Multiplying Equation 3 by 2, we get:

2v + 6b = 240

Subtracting this equation from Equation 2, we can eliminate v:

2v + 5b - (2v + 6b) = 204 - 240

b = -36

Dividing both sides of the equation by -1, we find:

b = 36

Now, substituting the value of b back into Equation 3:

v + 3(36) = 120

v + 108 = 120

v = 12

Therefore, a van can carry 12 students, and a bus can carry 36 students.
