For instance, we might simply show the following conditional statement:
1. Return true if the array's size is zero or one.
2. Verify the last two members of the array; if they are sorted, call n-1 times in a recursive fashion; otherwise, return false.
In the given question, we have to state true or false for the given statement.
In our programs, we frequently want to be able to "conditionally" execute certain actions, i.e., "if this is true, then do X, but if this other thing is true, then do Y." It's similar to how we dress when we get out of bed: "If it's sunny, I wear sunglasses, but if it's raining, I take an umbrella." In our programs, we can use if statements, if/else statements, and conditional expressions to do things conditionally.
If a condition is true, an if statement instructs the computer to run a certain piece of code. Only if x is bigger than 0 do we output a message in the following code:
We would be able to see the message on the canvas since x is 5, which is bigger than 0. If we modified x to -1, the message wouldn't appear at all because x wouldn't be greater than 0.
A conditional expression is one that can only be evaluated as either true or false, and the x > 0 qualifies as one. A boolean value is one that can only be either true or false (as opposed to a number or a string). For instance, we might simply show the following conditional statement:
1. Return true if the array's size is zero or one.
2. Verify the last two members of the array; if they are sorted, call n-1 times in a recursive fashion; otherwise, return false.

What is a trigonometric equation?A trigonometric equation is an equation that contains the trigonometric ratios.
How to solve the trigonometric equation for the set of real numbers?Given the trigonometric equation
√(sin²x - 4sinx + 4) + √(sin²x + 4sinx + 4) = √(sin²x + 7sinx + 12.25)
We know that sin²x - 4sinx + 4 = (sinx - 2)².
Also, sin²x + 4sinx + 4 = (sinx + 2)².
Also, sin²x + 7sinx + 12.25 = (sinx + 3.5)².
So, substituting these into the equation, we have that
√(sin²x - 4sinx + 4) + √(sin²x + 4sinx + 4) = √(sin²x + 7sinx + 12.25)
√(sinx - 2)² + √(sinx + 2)² = √(sinx + 3.5)²
|sinx - 2| + |sinx + 2| = |sinx + 3.5|
(2 - sinx) + (sinx + 2) = (sinx + 3.5)
2 - sinx + sinx + 2 = sinx + 3.5
Colecting like terms, we have that
-sinx + sinx + 2 + 2 = sinx + 3.5
0 + 4 = sinx + 3.5
4 = sinx + 3.5
Subtracting 3.5 from both sides, we have that
sinx = 4 - 3.5
sinx = 0.5
Taking inverse sin, we have that
x = sin⁻¹(0.5)

By Angle-Angle-Side (AAS) triangle congruence theorem we know that two triangles are congruent if they have two sets of congruent angles and a set of non-included congruent sides.
Since no figure is given in the question we employ the reflexive characteristic to demonstrate that the overlapping sections are congruent in order to demonstrate that overlapping triangles are congruent.
If two triangles are precisely the same size and shape—that is, if they have the same side lengths and angle measurements—they are said to be congruent. If we are aware that two triangles have all the same sides and angles, we can conclude that the triangles are congruent.
To demonstrate that two triangles are congruent, however, we don't necessarily need to know that all of their sides and angles are congruent.

Assuming at least 20 people sign up for the cruise, determine how many passengers will result in the maximum revenue for the owner of the yacht? What is the maximum revenue?
69 Passengers (20 plus additional 49) will result in maximum revenue for the owner of the yacht. Maximum Revenue will be $38,088.
current: 20 passengers at $944 each
let the number of additional passengers be x
cost per passenger = 944 - 8x
revenue (R) = (20+x)(944-8x)

Assume that a normal distribution of data has a mean of 19 and a standard deviation of 5. Use the 68-95-99. 7 rule to find the percentage of values that lie about 29.What percentage of values lie above 29?___% (Type an integer or a decimal.)
2.5% of values will lie above 29.
What is normal distribution?
A continuous probability distribution for a real-valued random variable in statistics is known as a normal distribution or Gaussian distribution.
The 68-95-99.7 rule is an illustration of how those many percentage of values lie in between mean +/- 1, 2, and 3 standard deviations respectively.
For values to lie above 29, their z value comes out to be
(29-19) / 5 = 10/5 = 2
(Note: z value means how many standard deviations above the mean)
Thus for a z value = 2 (which 29 is in this problem) the percentage of values that lie between mean +/- 2*(standard deviation) is 95 (as stated by the 68-95-99.7 rule).
Thus only 5% values wont lie between mean +/-2 standard deviations.
So 5% values wont lie between 29 (z value=2) and 9 (z value=-2).
Since normal curve is symmetric, half of the values of the 5% will lie above 29 and the rest half will lie below 9.
So 50% of 5 % which is 2.5% of values will lie above 29.
Hence, 2.5% of values will lie above 29.

In a T test, the T statistic is used to help you decide whether to accept or reject the null hypothesis.
You utilize it in a manner that is quite similar to using a Z-score. When you don't know the population standard deviation or have a limited sample size, you use the t statistic.
You employ the T statistic with a p value while performing a hypothesis test. Your results' likelihood of being the result of chance is indicated by the p-value. Typically, in statistics, you use a T Test with a T Statistic rather than a Z score because you don't know much about the population.

Ticket sales for Six Flags White Water totaled $94,520 this summer. Tickets for the water park cost $17 each. How many tickets were sold?
The number of tickets that will be sold is 5,560.
What is division?
A division is one of the fundamental mathematical operations that divides a larger number into smaller groups with the same number of components. How many total groups will be established, for instance, if 20 students need to be separated into groups of five for a sporting event? The division operation makes it simple to tackle such issues. Divide 20 by 5 in this case. 20 x 5 = 4 will be the outcome. There will therefore be 4 groups with 5 students each. By multiplying 4 by 5 and receiving the result 20, you may confirm this value.

This is so confusing could anyone help me with this
Answer:
I am not exactly sure what they want you to put in the boxes, but hopefully the explanation below will shed some light on what is going on with this problem.
Step-by-step explanation:
The equation would be
y = 3x
It looks like your question wants you to write the equation in the form
r(x) = 3x
y would be the student's score on the test.
x would be the number of questions that the student got right.
The x is the independent variable. It tells us how many questions the student got right.
The y is the dependent variable. It is the student's score. The student's score depends on how many questions the student got right.
R(25) is saying what would be the score if the student got 25 answer correct?
3(25) = 75. The student would get a score of 75

Is 1 is a root of f/x Which of the following must be true?
According to Polynomial System, the correct answer is that the roots of f(x) are (x+1).
A polynomial system (sometimes just a polynomial system) is a set of simultaneous equations f₁ = 0,..., fₙ = 0. where fi is a polynomial in multiple variables such as x₁,..., xₙ over the fields. k.
This is due to the zero product property that when two binomials are multiplied by 0, one of their factors must be 0.
A simple example of a system of polynomial equations is
x²+y²- 5 = 0
xy-2 = 0.
Its solutions are the four pairs (x, y) = (1, 2), (2, 1), (-1, -2), (-2, -1). These solutions are easily verified by substitution, but proving that there are no other solutions requires more work.
Based on above description, we can say that:
(x+1) must be 0.
(x+1)=0
x=-1
Thus, If (x-1)=0 then x is 1 instead of -1 in question.

Solve for h when they are similar triangles and 2 sides are given
The value of h is 70/17 if they are similar triangles and two sides are given in the figure.
What is a triangle?Three edges and three vertices make up a triangle, which is a polygon.
In Euclidean geometry, any three points that are not collinear identify a distinct triangle and a distinct plane at the same time (i.e. a two-dimensional Euclidean space). In other words, every triangle is contained in a plane, and that triangle is contained in just one plane. All triangles are enclosed in a single plane if all of geometry is the Euclidean plane, however in higher-dimensional Euclidean spaces, this is no longer the case. Except as specifically stated, this article is about triangles in the Euclidean plane and general Euclidean geometry.
Given,
The figure has two similar triangles.
Here in the question the two sides are given,
We have the condition,
1/AB +1/PC=1/MN

rewrite the sentence adding a nonrestrictive element. using commas Mr. Powel told us we have a geometry test next week
Mr. Powel, who is our geometry teacher, told us we have a geometry test next week.
What is non-restrictive element?A nonrestrictive element is an element of a sentence that is not necessary for understanding the basic meaning of the sentence, but instead provides additional information. Nonrestrictive elements are usually set off with commas, while restrictive elements are not. For example, “My brother, who is an engineer, works in Chicago” is a sentence with a nonrestrictive element. The nonrestrictive element (“who is an engineer”) provides additional information about the brother, but does not provide any information about which brother is being referred to. The restrictive element “My brother who works in Chicago” does provide information about which brother is being referred to.
