What is data set?

A data set is a collection of data, usually presented in tabular form, that can be analyzed to draw conclusions or make decisions. It can be numerical or categorical and can come from various sources such as surveys, experiments, or observations.

A data set typically contains individual data points or observations, each representing a unit or subject being studied. The size of a data set can range from small (e.g., a few observations) to large (e.g., millions of observations).

The computation of FV in Excel is shown in the attachment below:

Using the current number as a starting point, subtract the prior value to determine the growth rate. To calculate the growth rate in percentage terms, divide the difference by the previous amount and multiply the result by 100. Growth Rate equals (Ending Value - Beginning Value) - 1. The year-over-year (YoY) growth rate of a business, for instance, would be 20% if its revenue increased from $100 million in 2020 to $120 million in 2021.

GDP, turnover, wages, etc., all have growth rates that reflect how much they have changed over time (month, quarter, year). Percentages are a pretty common way to communicate it.

  x^2 +3x +2 = 0 . . . . . . . . . . simplify

  (x +2)(x +1) = 0 . . . . . . . . . . . factor

Values of x that make these factors zero are solutions:

Step-by-step explanation:

The solution to the given composite function is: -27

Composite functions are defined as when the output of one of a given function is used as the input of another function. If we have a function f and another function g, then we can say that the function fg(x) which is called “ f of g of x”, is the composition of the two functions.

We are given the function as:

g(2x - 5) = 8x - 19

Thus:

g o g(2)

g(2) = 2(2) - 5

= -1

g(-1) = 8(-1) - 19

= -8 - 19

= -27

The concept being demonstrated here is the multiplication of two decimal numbers.

When multiplying decimal numbers, we follow these steps:

- Ignore the decimal points and multiply the numbers as if they were whole numbers.

In this case, we multiply 548 by 245, which gives us 134,260.

- Determine the total number of decimal places in the original numbers.

In this case, the original numbers have a total of four decimal places (two decimal places each).

- Place the decimal point in the product so that it has the same number of decimal places as the total from step 2.

In this case, we need to place the decimal point two places from the right, giving us 1,342.60.

- Round the final result if necessary.

In this case, rounding to two decimal places gives us 1,342.60 rounded to 13.43.

Therefore,

The final value is 13.43, which represents the product of 5.48 and 2.45.

Step-by-step explanation:

We can see that 64= 4*4*4= 4^3, replacing 64 with 4^3 in the equation:

Thus, the measure of angle  m∠SQP = 87° for given set of vertically opposite angles.

An adjacent pair of additional angles is known as a linear pair. Adjacent refers to being next to one another, and supplemental denotes that the sum of the two angles is 180 degrees.

Any two angles that sum up to 180 degrees are referred to as supplementary angles.

For the given question:

m∠PQT = m∠SQR (vertically opposite)

101 - 4b = 109 - 6b

on simplifying:

109 - 101 = 6b - 4b

2b = 8

b = 4

m∠PQT = 101 - 4(4) = 93

Now,

m∠PQT +  m∠SQP = 180 (linear pair)

93 +  m∠SQP = 180

m∠SQP = 180 - 93

m∠SQP = 87°

Thus, the measure of angle  m∠SQP = 87° for given set of vertically opposite angles.

Answer: \(y = -\frac{1}{2} x -8\)

Step-by-step explanation:

Going to build the equation in slope-intercept form, let me know if you need another form :)

Slope intercept form: y = mx + b, where m is the slope and b is the y-intercept.

Simply plug in the slope for m to get: y = -1/2x + b.

Then simply plug in the point to get:

-6 = -1/2(-4) + b

-6 = 2 + b

b = -8

Answer:

100

Step-by-step explanation:

Given that 2 ap's have same common difference

given that their 100th terms difference is 100

let the first no. of first series be a1 and second series be a2

then, a(1)100 - a(2)100=100 ---- 1

for 1st series ---- a100=a1+99d

   2nd series ---- a100 = a2+99d

keep these values in (1)

then,  

a1+99d - (a2+99d) = 100

a1+99d-a2-99d=100

therefore, a1-a2 =100 ------------------------------------------- 2

then the difference between their 1000th terms is

for 1st series --- a1000 = a1+999d

for 2nd series --- a1000 = a2+999d

their 100th terms difference is

a(1)1000-a(2)1000

a1+999d-(a2+999d)

a1+999d-a2-999d

therefore we get the value a1-a2

from (2) a1-a2 = 100

therefore the difference between their 1000th terms is 100

They will be when they pass each other at 44 4/9 mins.

This is a classic question on Speed, time, & distance.

1. When time traveled in each segment is constant, then average speed is simple mean of speeds.

2. When distance traveled in each segment is constant, then average speed is reciprocal of simple mean of reciprocal of speeds. It is basically called Harmonic mean.

So this question falls in the category of 2.

=> So, average speed = Reciprocal of mean of reciprocals of 40 & 50.

=> Average speed = Reciprocal of mean of 1/40 & 1/50.

=> Average speed = Reciprocal of (1/40 + 1/50)/2

= Reciprocal of (5+4)/400

= 44 4/9 mins

Hence, they will be when they pass each other at 44 4/9 mins.

We'll use the tangent ratio here

tan(angle) = opposite/adjacent

tan(x) = 5/7

x = arctan(5/7)

x = 35.5376777919743 approximately

x = 35.54

Answer:

there are 120 possible points in the sample space if we select 3 batteries at random from a bag containing 6 batteries of different brands.

Step-by-step explanation:

The counting principle states that if there are n ways to do one thing and m ways to do another, then there are n x m ways to do both.

In this case, we want to determine how many ways we can select 3 batteries out of 6. Using the counting principle, we can break down the selection process into three steps:

Select the first battery. There are 6 choices for the first battery.

Select the second battery. There are 5 choices left for the second battery, since we've already selected one.

Select the third battery. There are 4 choices left for the third battery.

Using the counting principle, we can multiply the number of choices for each step to get the total number of ways to select 3 batteries:

6 x 5 x 4 = 120

Therefore, there are 120 possible points in the sample space if we select 3 batteries at random from a bag containing 6 batteries of different brands.

Answer:

If 1% = 1050

To get 24% you need to multiply 1% by 24. Whatever you do to o ne side you have to do to the other.

1050 * 24 = 25,200

Therefore, the answer is 25,200 people

Answer:

The numerical limits for a D grade are 58(lower limit) and 61(upper limit).

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:

\(Z = \frac{X - \mu}{\sigma}\)

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.

Scores on the test are normally distributed with a mean of 67.3 and a standard deviation of 7.3.

This means that \(\mu = 67.3, \sigma = 7.3\)

D: Scores below the top 80% and above the bottom 9%

This means that lower bound is the 9th percentile and the upper bound is the 100 - 80 = 20th percentile.

9th percentile:

This is X when Z has a pvalue of 0.09. So X when Z = -1.34.

\(Z = \frac{X - \mu}{\sigma}\)

\(-1.34 = \frac{X - 67.3}{7.3}\)

\(X - 67.3 = -1.34*7.3\)

\(X = 57.52\)

Rounding to the nearest whole number, 58.

20th percentile:

This is X when Z has a pvalue of 0.2. So X when Z = -0.84

\(Z = \frac{X - \mu}{\sigma}\)

\(-0.84 = \frac{X - 67.3}{7.3}\)

\(X - 67.3 = -0.84*7.3\)

\(X = 61.17\)

Rounding to the nearest whole number, 61.

The numerical limits for a D grade are 58(lower limit) and 61(upper limit).
