In conditional statements, the part of the statement following 'if' is called the antecedent.

The antecedent is the condition that needs to be true for the consequent to occur.

The consequent is the part of the statement that follows 'then.'

An antecedent is a noun or pronoun that denotes a specific being, place, object, or clause.

It's also referred to as a referent. Without an antecedent, a sentence may be insufficient or nonsensical since it is

required to establish what or to whom a pronoun in a sentence is referring.

In summary, a conditional statement is structured as "if (antecedent) then (consequent)."

Answer:

Square

Step-by-step explanation:

In a square,

All the four angles are equal. Each angle = 90.

All the four sides are equal.

Answer:

point-slope form, standard form, and slope-intercept form

Step-by-step explanation:

The three main types of linear functions are: point-slope form, standard form, and slope-intercept form.

Here is an image with each form

a) The minimum number of wins he needs is 15. b) The standard deviation of X is σ = sqrt(Var(X)) ≈ 3.641. c) Standard normal table ≈ 0.411.

In part (a), we can use the formula for a binomial distribution to find the minimum number of wins Sam needs to break even. Let X be the number of wins in 520 spins, then X ~ Bin(520, 1/38). To break even, Sam needs to win at least $520, which means he needs at least m wins where 35m ≥ 520, or m ≥ 14.86. Since m must be an integer, the minimum number of wins he needs is 15.

In part (b), we can use the mean and variance of a binomial distribution to find the mean and standard deviation of X. The mean of X is E(X) = np = 520*(1/38) ≈ 13.684, and the variance of X is Var(X) = np(1-p) = 520*(1/38)*(37/38) ≈ 13.255. Therefore, the standard deviation of X is σ = sqrt(Var(X)) ≈ 3.641.

In part (c), we can use the Normal approximation to the binomial with the continuity correction to find P(X ≥ 15). Using the continuity correction, we can convert the discrete probability P(X ≥ 15) to a continuous probability P(X > 14.5). Standardizing X, we get Z = (14.5 - 13.684) / 3.641 ≈ 0.224. Using a standard normal table, we can find that P(Z > 0.224) ≈ 0.411. Therefore, P(X > 14.5) ≈ 0.411.

This answer is closer to the exact probability of 0.396 than the previous estimate of 0.10 too large, but it still overestimates the probability slightly. This could be due to the fact that the Normal approximation to the binomial assumes a continuous distribution, while the binomial distribution is discrete. Nonetheless, the Normal approximation with continuity correction is a useful tool for approximating probabilities in situations where the sample size is large.

A vector graphic consists of a set of instructions for creating a picture is a true statement.

Step-by-step explanation:

A vector graphic is an image format that represents images as a set of mathematical instructions or geometric primitives such as lines, curves, and shapes. Instead of using a grid of pixels like raster graphics, vector graphics define images based on mathematical formulas and coordinates.

These instructions or mathematical representations describe the shapes, colors, and other visual attributes of the image. They allow the image to be scaled, resized, and manipulated without loss of quality since the instructions can be recalculated and redrawn at any resolution or size.

Vector graphics are often created and edited using specialized software such as Adobe Illustrator, CorelDRAW, or Inkscape. They are commonly used for logos, illustrations, diagrams, typography, and other graphical elements where scalability and flexibility are important.

As per the temperature, the population of Salmonella bacteria in the salad will double approximately every 2.87 hours if the conditions for growth remain constant.

The population of Salmonella bacteria can increase over time if they have the necessary nutrients and temperature for growth. In this case, we have a cutting board contaminated with Salmonella bacteria, which ends up in a salad. The number of bacteria present in the salad after t hours is given by the formula S(t) = 250 x 6t, where t is the time in hours.

To understand how often the population of bacteria doubles, we need to look at the growth rate of the bacteria.

To calculate the doubling time, we can use the formula Td = ln(2) / r, where Td is the doubling time, ln is the natural logarithm, and r is the exponential growth rate. In this case, the growth rate can be found by taking the derivative of S(t) with respect to t, which gives us r = 6ln(6).

Plugging in the values, we get Td = ln(2) / 6ln(6) = 2.87 hours

The area under a curve can be written as a limit of Riemann sums. Riemann sums are used to estimate the area of a curve. To find the area of a curve, it is divided into small rectangles whose combined areas approximate the area of the curve. The limit of the sum of the areas of these rectangles is the exact area of the curve.

The Riemann sum is given by the formula:

Riemann sum = (b-a)/n ∑ f(xi)

The limit of the Riemann sum is given by the formula:

lim [ (b-a)/n ∑ f(xi) ]

The limit of the Riemann sum gives the precise area under a curve. Unfortunately, the limit can only be determined for specific curves. For example, if the curve is described by a simple function like y = x2 or y = sin(x), the limit may be calculated using calculus. Riemann sums may be used to estimate the area of a curve by splitting it into a finite number of rectangles of equal width.

The area of each rectangle is then determined by multiplying the height of the curve by the width of the rectangle. Summing the areas of each rectangle yields the overall area. The precise area under a curve is the limit of the Riemann sum. Nonetheless, the limit can be exceeded. The limit of the Riemann sum is the exact area under a curve. However, the limit can only be evaluated for certain curves using calculus.

Step-by-step explanation:

The largest possible error in the area of the circle is of 44%.

The area of a circle of radius r is given by:

\(A = \pi r^2\)

With a diameter of 20 cm = radius of 10 cm, the area in cm² is given by:

\(A = \pi \times 10^2 = 100\pi\)

With the error, with a diameter of 20 x 1.2 = 24 cm = radius of 12 cm, the area in cm² is given by:

\(A = \pi \times 12^2 = 144\pi\)

The error is given by:

\(E = 144\pi - 100\pi = 44\pi\)

The percent error is the error divided by the initial amount, multiplied by 100%, hence:

Answer:

y=bc-abx

Step-by-step explanation:

Given the equation ax + y/b = c, the first thing you'd want to do is isolate the variable that you are trying to solve for.

To do this, you must first subtract ax from both sides, to leave y/b by itself on one side of the equation, resulting in:

y/b = c - ax

Now all you need to do to isolate y, and you can do so by multiplying both sides by b, cancelling out y being divided by b.

b(y/b) = b(c - ax)

y = b(c - ax)

To simplify and fit one of the answer choices, you simply distribute b via multiplication to both c and -ax:

Answer:

1. \(3 : 2 = H : C\)

2. \(2 : 3 = C : H\)

3. \(2 : 2 = O : T\)

4. \(13 : 3 = All\ Letters : H\)

5. \(2 : 13 = E : All\ Letters\)

Step-by-step explanation:

See comment for complete question.

We have the following letters and their frequencies

\(C = 2\)     \(H = 3\)   \(A = 2\)   \(T = 2\)   \(O = 2\)  \(E = 2\)

Solving (1): 1. \(3 : 2 = H : [\ ]\)

From the alphabets listed above:

\(H = 3\),       \(C = 2\)   \(A = 2\)   \(T = 2\)   \(O = 2\)  \(E = 2\)

So, the 3:2 can be H : any of the alphabets. For this solution, we use:

\(3 : 2 = H : C\)

Solving (2) \(2 : 3 = [\ ] : H\)

This is the inverse of (1) solved above.

So 2 : 3 is:

\(2 : 3 = C : H\)

Solving (3) \(2 : 2 = O : [\ ]\)

From the alphabets listed above:

\(C = 2\)   \(A = 2\)   \(T = 2\)   \(O = 2\)  \(E = 2\)

Any selected alphabet will represent 2 : 2

So, we have:

\(2 : 2 = O : T\) or O : any of C, A and E

Solving (4):. \(13 : 3 = [\ ] : H\)

The total of all alphabet in the given word is: 13.

So,

\(13 : 3 = All\ Letters : H\)

Solving (5): \(2 : 13 = E : [\ ]\)

The total of all alphabet in the given word is: 13.

So,

\(2 : 13 = E : All\ Letters\)
