Answer:

is correct

x^3 -7x^2+2x +40

multiply the constants of the factors (each factor has opposite sign of the zero)

(x+2)(x-4)(x-5)   2(-4)(-5) = 40,  that eliminates all but c) and d)

(x+2)(x-4)(x-5) = (x^2-2x-8)(x-5)   by using FOIL on the 1st two factors

then (-8)(-5) = +40, eliminating a) and b), leaving only c) and d)

-5 times -2x = 10x,  x times -8 = -8x.   10x-8x = 2x which c) has but d) doesn't.

Answer:

B. making an inference.

Step-by-step explanation:

The drama teacher's decision to add another performance time on Saturday is a result of making an inference based on the information that 80% of last year's sold-out plays occurred during weekend performances. By observing this pattern, the drama teacher infers that adding another performance on Saturday will likely attract a larger audience and increase the chances of having a sold-out show.

Answer:

\(P(Republican) = 0.2857\)

\(P(Better) = 0.1091\)

\(P(better | Republican) = 0.2043\)

\(P(Republican | better) = 0.5352\)

\(P(Republican\ n\ Better) = 0.0584\)

Step-by-step explanation:

Given

---------------------better same worse

Republican ------38 -----104 --- 44

Democrat --------12 -------87 --- 137

None --------------21 --------90 ----118

\(Total = 651\)

Solving (a): P(Republican)

Here, we consider the "republican" row only;

\(n(Republican) = 38 + 104 + 44\)

\(n(Republican) = 186\)

\(P(Republican) = \frac{n(Republican)}{Total}\)

\(P(Republican) = \frac{186}{651}\)

\(P(Republican) = 0.2857\)

Solving (b): P(Better)

Here, we consider the "better" column only

\(n(Better) = 38 + 12+21\)

\(n(Better) = 71\)

\(P(Better) = \frac{n(Better)}{Total}\)

\(P(Better) = \frac{71}{651}\)

\(P(Better) = 0.1091\)

Solving (c): P(better | Republican)

This is calculated as:

\(P(better | Republican) = \frac{P(better\ n\ Republican)}{P(Republican)}\)

For, P(better n Republican), we consider the cell where "Better" and "Republican" intersects;

i.e. \(n(Better\ n\ Republican) = 38\)

\(P(Better\ n\ Republican) = \frac{38}{651}\)

So:

\(P(better | Republican) = \frac{P(better\ n\ Republican)}{P(Republican)}\)

\(P(better | Republican) = \frac{38}{651}/\frac{186}{651}\)

\(P(better | Republican) = \frac{38}{651} * \frac{651}{186}\)

\(P(better | Republican) = \frac{38}{186}\)

\(P(better | Republican) = 0.2043\)

Solving (d): P(Republican | better)

This is calculated as:

\(P(Republican | better) = \frac{P(Republican\ n\ better)}{P(better)}\)

\(P(Republican\ n\ Better) =P(Better\ n\ Republican) = \frac{38}{651}\)

So:

\(P(Republican | better) = \frac{P(Republican\ n\ better)}{P(better)}\)

\(P(Republican | better) = \frac{38}{651}/\frac{71}{651}\)

\(P(Republican | better) = \frac{38}{651} * \frac{651}{71}\)

\(P(Republican | better) = \frac{38}{71}\)

\(P(Republican | better) = 0.5352\)

Solving (e): P(Republican and better)

\(P(Republican\ n\ Better) =P(Better\ n\ Republican) = \frac{38}{651}\)

\(P(Republican\ n\ Better) = 0.0584\)

The disadvantages of the mode are: For many sets of data there is no mode.

The mode is a measure of central tendency that represents the most frequently occurring value in a dataset.

However, one of the disadvantages of the mode is that for many sets of data, there may not be a distinct mode. In such cases, the data may have a uniform distribution where all values occur with equal frequency, or it may have multiple modes with similar frequencies.

The mode is not affected by extremely large or small values. It only considers the frequency of values and not their magnitude. Therefore, extreme values do not influence the mode.

The statement that the mode can only be computed for interval-level data or higher is incorrect. The mode can be computed for any type of data, including nominal, ordinal, interval, and ratio data. It is applicable to categorical as well as numerical data.

The main disadvantage of the mode is that for many datasets, there may not be a distinct mode.

The correct option is: For many sets of data there is no mode.

Answer:

100°

Step-by-step explanation:

tThe sum of all arc measures that make up that circle is 360 degrees.

QS + RQ + RS = 360

QS = 360 - 120 - 140 = 100

An arc angle is the degree measurement of that angle inside the circle, opposite the arc

m∠R = arc QS = 100°

Answer:

∠ R = 50°

Step-by-step explanation:

the inscribed angle R is half the measure of its intercepted arc QS

the sum of the arcs on a circle is 360° , that is

RQ + QS + SR = 360°

120° + QS + 140° = 360°

QS + 260° = 360° ( subtract 260° from both sides )

QS = 100°

Then

∠ R = \(\frac{1}{2}\) × 100° = 50°

Answer:

the value of a - b is 4.

Step-by-step explanation:

We have been given the following two equations:

a + b = 10 ------------(1)

a² - b² = 40 -------(2)

We can factor the left-hand side of equation (2) using the difference of squares identity:

(a + b)(a - b) = 40

Substituting equation (1) into this equation, we get:

10(a - b) = 40

Dividing both sides by 10, we get:

a - b = 4

Therefore, the value of a - b is 4.

Step-by-step explanation:

if I understand this correctly :

a + b = 10

a² - b² = 40

(a² - b²) = (a + b)(a - b) = 40

10(a - b) = 40

(a - b) = 4

There are a total of 332640 ways to choose 6 letters from 11 letters without replacement

From the question, we have the following characters that can be used in our computation:

Letters to select = 6

Available letters = 11

From the question, we understand that the selection is without replacement

This means that we make use of permutation

The number of ways of selection could be drawn is calculated using the following permutation formula

Total = ⁿPᵣ

Where

n = 11 and r = 6

Substitute the known values in the above equation

Total = ¹¹P₆

Apply the permutation formula

ⁿPᵣ = n!/(n - r)!

So, we have

Total = 11!/5!

Evaluate

Total = 332640

Hence, the number of ways to choose the letters is 332640 ways

The correct answer is cycle. A sine or a cosine function represent periodic functions where the value of the function is repeats after a definite interval.

What do you mean by periodic function?

A periodic function can be defined as:

A function returning to the same value at regular intervals. Though periodic motion and oscillatory motion sound the same, not all periodic motions will be oscillatory motion.

Image result for periodic function

If a function has a repeating pattern like sine or cosine, it is called a periodic function. The period is the length of the smallest interval that contains exactly one copy of the repeating pattern.

A motion that repeats itself at regular intervals is termed periodic motion. 1. A motion that does not repeat itself at regular intervals is termed non-periodic motion. 2. After a certain period of time, an object exhibiting periodic motion returns to its original position.

Answer: -6

Step-by-step explanation:

The equivalent ratios are 8: 6 and 12:9.    

Two ratios are equivalent if they represent the same proportion or relative size. To find an equivalent ratio, we can multiply both terms of the ratio by the same non-zero number. This doesn't change the condition between the two terms.  

Here we have 4:3

To find equivalent ratios, we can multiply both terms by the same number.

Multiplying by 2

Hope this helps

Answer:

b = 56km is the answer.

Step-by-step explanation:

a (Northbound train) = 33km

b (Eastbound train) = ?

c (Distance between them) = 65km

According to the Pythagorean theorem,

a² + b² = c²

33² + b² = 65²

1089 + b² = 4225

b² = 4225 - 1089

b² = 3136

b = 56km

∴ the eastbound train has travelled 56km.

The supplement of BIE equals the supplement of GMD is a false assertion if lines BG and CF are parallel.

Angles with a supplementary sum are those whose sum is 180 degrees. For instance, the total of angle 130° and angle 50° is 180°, hence they are supplementary angles.

Lines BG and CF are parallel, as shown in the figure.

If BIE = X, then its supplement of BIE will be 180 - X;

similarly, if GMD = Y, then its supplement of GMD will be 180 - Y.

Since BG and CF are parallel, the supplements of BIE and GMD are interior angles on the same side ( as shown in figure)

and for parallel line the interior angle on the same side is 180

so 180 - X and 180 -Y there sum should be 180

They cannot be equal

line BG and CF are parallel, then the supplement of BIE = the supplement of GMD are not equal.

The minimum exam score to be awarded an A is about 8.52.

Step-by-step explanation:

Let X represent the scores on a common final exam.

It is provided that X follows a normal distribution with mean, μ = 71 and standard deviation, σ = 9.

It is provided that according to the department policy is that the top 10% of students receive an A.

That is, P (X > x) = 0.10.

⇒ P (X < x) = 0.90

⇒ P (Z < z) = 0.90

The corresponding z-score is:

z = 1.28

Compute the value of x as follows:

\(z=\frac{x-\mu}{\sigma}\\\\1.28=\frac{x-71}{9}\\\\x=71+(1.28\times 9)\\\\x=82.52\)

Thus, the minimum exam score to be awarded an A is about 8.52.
