Higher than 172

150

Answers

Answer 1

I need to score 172 in the 14th game to have an average of 152 in 14 games.

What is the weighted average?

When the average is not of any individual rather it is an average of two or more groups or sets it is called a weighted average.

To obtain the weighted average we multiply no. of individuals by their averages and sum the next group in the previous procedure and divide them by the total no. of individuals.

The total score of 12 games is (12×150) = 1800.

Again I scored 156 is the 13th game.

Let I score 'x' in the 14th game.

(1800 + 156 + x)/12 + 1 + 1 = 152.

(1800 + 156 + x)/14 = 152.

(1956 + x)/14 = 152.

1956 + x = 2128.

x = 2128 - 1956.

x = 172.

So, I need to score 172 in order to have an average of 152 for 14 games.

In a population where 25% of voters prefer Candidate A, an organization conducts a poll of 9 voters. Find the probability that 2 of the 9 voters will prefer Candidate A.

(Report answer accurate to 4 decimal places.That is, round to 4 decimal places.)

Answers

The probability that 2 of the 9 voters will prefer Candidate A is 0.30033

Given that 25 % of voters prefer candidate A

Total number of voters = 9

Do we have to calculate the probability that 2 of the 9 voters will prefer Candidate A =?

In this question, we used binomial distribution to find the probability that 2 of the 9 voters will prefer candidate A.

The binomial distribution follows the probability  mass function of:

⁹C₂ * (0.25) ² *  (0.75)⁷ =>

⁹C₂  = (9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1)/ (7 * 6 * 5 * 4 * 3 * 2 * 1) (2 * 1) =>

⁹C₂  = 9 * 8/2 = 36

Now, 36 * (1/4)² * (3/4)⁷ = 0.30033

g which of the following is the most effective way to describe multivariate relationships? group of answer choices schedules graphs equations schedules and graphs

Answers

The most effective way to describe multivariate relationships is by means of graphs and multiple variables.

The term "multivariate analysis" refers to a broad variety of statistical methods, not simply one particular approach. These methods enable you to comprehend your data more thoroughly in light of particular commercial or real-world settings.

Multivariate analysis is therefore a key idea to understand if you're wanting to be a data analyst or data scientist.

The breadth of knowledge that multivariate analysis offers is its one key benefit. The insights you find are far more applicable to the actual world because you're drawing a lot more thorough picture of what's happening when you explore numerous factors.

There are two different kinds of multivariate analytic techniques: interdependence techniques, which examine the structure of a dataset, and dependency techniques, which examine the cause-and-effect interactions between variables.

Answer:

[tex]\textsf{b)} \quad a_n=3n-4[/tex]

Step-by-step explanation:

Sequence a

Given sequence:

1, -1, 1, -1, 1, ...

The given sequence is geometric since there is a common ratio of -1 between consecutive terms.

To find the common ratio of a geometric sequence, divide a term by the previous term:

[tex]\dfrac{a_5}{a_4}=\dfrac{1}{-1}=-1[/tex]

[tex]\dfrac{a_4}{a_3}=\dfrac{-1}{1}=-1[/tex]

[tex]\dfrac{a_3}{a_2}=\dfrac{1}{-1}=-1[/tex]

[tex]\dfrac{a_2}{a_1}=\dfrac{-1}{1}=-1[/tex]

[tex]\boxed{\begin{minipage}{5.5 cm}\underline{Geometric sequence}\\\\$a_n=ar^{n-1}$\\\\where:\\\phantom{ww}$\bullet$ $a$ is the first term. \\\phantom{ww}$\bullet$ $r$ is the common ratio.\\\phantom{ww}$\bullet$ $a_n$ is the $n$th term.\\\phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}[/tex]

Given:

a = 1r = -1

Substitute the values of a and r into the formula to create an equation for the nth term:

[tex]\implies a_n=1 \cdot (-1)^{n-1}[/tex]

[tex]\implies a_n=(-1)^{n-1}[/tex]

Sequence b

Given sequence:

-1, 2, 5, 8, 11, ...

The given sequence is arithmetic since there is a common difference of 3 between consecutive terms.

To find the common difference of an arithmetic sequence, subtract consecutive terms:

[tex]a_2-a_1=2-(-1)=3[/tex]

[tex]a_3-a_2=5-2=3[/tex]

[tex]a_4-a_3=8-5=3[/tex]

[tex]a_5-a_4=11-8=3[/tex]

[tex]\boxed{\begin{minipage}{8 cm}\underline{General form of an arithmetic sequence}\\\\$a_n=a+(n-1)d$\\\\where:\\\phantom{ww}$\bullet$ $a_n$ is the nth term. \\ \phantom{ww}$\bullet$ $a$ is the first term.\\\phantom{ww}$\bullet$ $d$ is the common difference between terms.\\\phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}[/tex]

Given:

a = -1d = 3

Substitute the values of a and d into the formula to create an equation for the nth term:

[tex]\implies a_n=-1+(n-1)3[/tex]

[tex]\implies a_n=-1+3n-3[/tex]

[tex]\implies a_n=3n-4[/tex]

What is the equation of the circle with center (-4, -1) and radius 3?

Answers

The equation of the circle for all the given values is obtained as  x² + y² + 8x + 2y + 8 = 0.

How to write an equation for a circle?

The equation for a circle can be written by knowing the coordinates of its centre and the length of its radius.

Since the radius is the distance from the centre to a point on the circle, the equation can be written by distance formula as s (x - h)² + (y - k)² = r² where (h, k) is the coordinate of the centre.

The coordinates of the centre of the circle is given as (-4, -1).

And, the radius is 3.

The general equation of the circle for centre at (h, k) and radius r is given as (x - h)² + (y - k)² = r².

Substitute the corresponding values to obtain,

(x - h)² + (y - k)² = r²

=> (x - (-4))² + (y - (-1))² = 3²

=> (x + 4)² + (y + 1)² = 9

=> x² + 8x + 16 + y² + 2y + 1 = 9

=> x² + y² + 8x + 2y + 8 = 0

Hence, the required equation for the circle is given as  x² + y² + 8x + 2y + 8 = 0.

what are the coordinates of the centroid of ABC with vertices A (-3, 1), B (-2, 4), and C (5, -2)

Answers

Answer:

(0, 1/3)

Step-by-step explanation:

To find the centroid of a triangle with vertices A, B, and C, we can use the following formula:

centroid = (x1 + x2 + x3) / 3, (y1 + y2 + y3) / 3

where (x1, y1), (x2, y2), and (x3, y3) are the coordinates of the vertices A, B, and C, respectively.

In this case, we have A = (-3, 1), B = (-2, 4), and C = (5, -2), so the centroid of the triangle is:

centroid = ((-3) + (-2) + 5) / 3, (1 + 4 + (-2)) / 3 = (0, 1/3)

Therefore, the coordinates of the centroid of ABC are (0, 1/3).

What is equation of line in slope intercept form?

The most general form of equation of line in slope intercept form is given by y = mx + c

Where m is the slope of the line and c is the y intercept of the line.

Slope of a line is the tangent of the angle that the line makes with the positive direction of x axis.

If [tex]\theta[/tex]  is the angle that the line makes with the positive direction of x axis, then slope (m) is given by

m = [tex]tan\theta[/tex]

The distance from the origin to the point where the line cuts the x axis is the x intercept of the line.

The distance from the origin to the point where the line cuts the y axis is the y intercept of the line.

Slope of the required line = [tex]\frac{2}{3}[/tex]

The line passes through (0, -2)

Equation of the required line =

[tex]y - (-2) = \frac{2}{3}(x - 0)\\y + 2 = \frac{2}{3}x\\y = \frac{2}{3}x-2[/tex]
