How would you define a graph ?

In mathematics, a graph is a visual representation or diagram that shows facts or values in an ordered way. The relationships between two or more items are frequently represented by the points on a graph.

How is a line graphed?

Draw a horizontal axis and a vertical axis first before drawing a line graph. Because age is independent, it should be plotted on the horizontal axis. Plotting should be done using height on the vertical axis. Plot a point for each pair of values using the data that has been provided.

A probability distribution is a statistical function that explains all the possible values of a random variable and their respective probabilities.

To restore the probability mass function of a random variable, we need to sum up all the probabilities. In this question, the sum of all the probabilities is equal to 1, as follows:

P x (x) = 5k + 0.24 + 3k + 0.2 = 1

Simplifying further, we get:8k + 0.44 = 1Therefore,

8k = 1 – 0.44 = 0.56k = 0.07

The probability mass function is given below :

x -2 -1 1 4Px(x) 0.35 0.24 0.21 0.

To find the probability that X is less than 3, we need to add up the probabilities for

X = -2, X = -1 and X = 1. P(X < 3) = P(X = -2) + P(X = -1) + P(X = 1) = 0.35 + 0.24 + 0.21 = 0.8

Similarly, to find the probability that X is greater than 3, we need to add up the probabilities for

X = 4.  P(X > 3) = P(X = 4) = 0.20

Therefore, the probability that X is less than 3 and greater than 3 is 0.8 and 0.2, respectively.

The binomial theorem, we can expand (u - 3v)⁴ as follows: (u - 3v)⁴ = 1u⁴ + 4u³(-3v) + 6u²(-3v)² + 4u(-3v)³ + 1(-3v)⁴= u⁴ - 12u³v + 54u²v² - 108uv³ + 81v⁴ and the coefficient of x⁷ is 2187.

(a) Using the binomial theorem, we can expand (u - 3v)⁴ as follows:

(u - 3v)⁴ = 1u⁴ + 4u³(-3v) + 6u²(-3v)² + 4u(-3v)³ + 1(-3v)⁴

= u⁴ - 12u³v + 54u²v² - 108uv³ + 81v⁴

(b) To find the coefficient of x⁷ in the expansion of (3x + 4)¹⁰, we need to look at the term that contains x⁷, which is the term where x has a power of 7 and the constant has a power of 3:

To reach your fundraising goal of $75, you will need to sell 150 pencils for $0.50 each and 0 bracelets for $1.00 each.

To reach your fundraising goal of $75, you can sell pencils for $0.50 and bracelets for $1.00.

1. Calculate the total amount of money needed to reach the goal:
  Goal amount = $75

2. Determine the number of pencils and bracelets you need to sell to reach the goal:
  Let's assume you sell x number of pencils and y number of bracelets.

  The amount raised from selling pencils = x * $0.50
  The amount raised from selling bracelets = y * $1.00

  The total amount raised from both items should be equal to the goal amount:
  x * $0.50 + y * $1.00 = $75

3. Simplify the equation:
  0.50x + 1.00y = 75

4. Solve for one variable in terms of the other:
  Let's solve for x in terms of y:
  0.50x = 75 - 1.00y
  x = (75 - 1.00y) / 0.50

5. Substitute the value of x into the equation:
  (75 - 1.00y) / 0.50 * 0.50 + y * $1.00 = $75
  75 - 2y + y = 75
  -y = 0
  y = 0

6. Find the value of x:
  x = (75 - 1.00 * 0) / 0.50
  x = 75 / 0.50
  x = 150

To reach your fundraising goal of $75, you will need to sell 150 pencils for $0.50 each and 0 bracelets for $1.00 each.

Answer:

Step-by-step explanation:

The ratio that will determine the size of x, y, z is 9 / 12 That comes about because 9 value is parallel to the 12 value when both are extended in either direction

x

9/12 = x / 22           Cross multiply

12x = 9 * 22

12x = 198                Divide by 12  on both sides

x = 198/12      

x = 16.5

y

y and 24 are related because they are parallel

9/12 = y/24            Cross multiply

12y = 9 * 24

12y = 216

y = 216 / 12

y = 18

z

See the solution for x. z = x

\(\frac{z}{22}\)Answer:

y = 18      x = 16.5     z = 16.5

Step-by-step explanation:

\(\frac{y}{24}\) = \(\frac{x}{22}\) = \(\frac{z}{22}\)= \(\frac{9}{12}\) = \(\frac{3}{4}\)

So,  \(\frac{y}{24}\) = \(\frac{3}{4}\)               \(\frac{x}{22}\) = \(\frac{3}{4}\)               \(\frac{z}{22}\) = \(\frac{3}{4}\)

Descriptive statistics is the process of summarizing and organizing data from a sample or population in order to provide an overview of the main characteristics. In this case, the data provided tells us that out of 25 students in the class, 40% are male.

This information is a summary of the gender distribution within this specific class, rather than making any predictions or generalizations about a larger population.

In contrast, inferential statistics is the process of using data from a sample to make predictions or draw conclusions about a larger population. If we were given data about a sample of classes and asked to estimate the proportion of male students in all classes, that would be an example of inferential statistics.

To summarize, the situation you provided, which states that out of 25 students in the class, 40% are male, is an example of descriptive statistics as it only provides a summary of the data for that specific class.

The increasing the sample size by a factor of 25 will reduce the width of the confidence interval by a factor of 5.

a. Suppose we have a two-sided confidence interval for the population mean with known variance, given by the equation:

Cl is the confidence interval, x is the sample mean, σ is the population standard deviation, n is the sample size, and zα/2 is the z-score corresponding to the desired level of confidence.

The σ are fixed for a given level of confidence, we can achieve this by increasing n by a factor of 4.

Specifically, if we increase the sample size from n to 4n, then the new confidence interval will have half the width of the original interval.

b. If the sample size is increased by a factor of 25, then the term √n in the denominator of the above equation will be replaced.

Therefore, increasing the sample size by a factor of 25 will reduce the width of the confidence interval by a factor of 5.

Answer:
Each pound of jelly beans costs $2.50 and each pound of almonds costs $1.25.

I really struggled while trying to solve this, good luck. (┬┬﹏┬┬)<3

Step-by-step explanation:

2.50*3 = 7.50
1.25*2 = 2.50

7.50 + 2.50 = 10.00

-------------------------------

2.50*8 = 20.00
1.25*4 = 5

20 + 5 = 25

The formula for allocation deviation is as follows:σA = (w1σ1^2 + w2σ2^2 + … + wσn^2)^(1/2)σB = (w1σ1^2 + w2σ2^2 + … + wσn^2)^(1/2)

Here,

σ1 = 15%

σ2 = 10%

w1 = 50%,

w2 = 50%

Substituting the values in the above formula:

σA = (0.5 × 0.15^2 + 0.5 × 0.10^2)^(1/2)

= (0.0225 + 0.0100)^(1/2)

= 0.0158 = 1.58%σB

= (0.5 × 0.15^2 + 0.5 × 0.10^2)^(1/2)

= (0.0225 + 0.0100)^(1/2)

= 0.0158

= 1.58%

Hence, the correct option is

D. σ(A) = 14.14%;

σ(B) = 16.33%.

Step-by-step explanation:

The bias based on the naive forecast method for the given data is 2.0.

To calculate the bias using the naive forecast method, we first need to calculate the average of the time series values. The formula for the naive forecast is simply taking the last observed value as the forecast for the next period.

The time series values given are 13, 19, 8, and 14. To find the average, we sum up these values and divide by the number of values:

Average = (13 + 19 + 8 + 14) / 4

= 54 / 4

= 13.5

Next, we take the last observed value, which is 14, as the forecast for the next period.

Finally, we calculate the bias by subtracting the average from the forecast:

Bias = Forecast - Average

= 14 - 13.5

= 0.5

Rounding the bias to 1 decimal place, we get a bias of 0.5, which can also be expressed as 2.0 when rounded to the nearest whole number.

Therefore, the bias based on the naive forecast method for the given data is 2.0.
