Three- month simple moving average (sma) forecast for the average gas prices are $3.08

$3.16 , $3.29 and predict the average retail gasoline price for june 2020 is $3.54.

A simple moving average (SMA) is defined as an arithmetic moving average calculated by adding recent prices and then dividing that figure by the number of time periods in the calculation average. The formula for SMA is:

SMA = (A₁ + A₂ + ------+ Aₙ )/n

where, Aₙ = the price of object at nth period

n = the number of total periods

We have, a average gas prices for different months. Calculate the three-month moving average, add together the first three sets of data, for this example it would be Dec, January, and February. This gives a total of $9.25 , then calculate the average of this total, by dividing this figure by 3 we get 3-month simple moving average. We have to predict the 3-month simple moving average for June 2020. As we seen in above table we calculate the 3-month simple moving average for different months.

The 3-month simple moving average for June 2020 is ( $3.29 + $3.51 + $3.82 )/3 = $3.54

So, required value is $3.54..

Answer:

\(g(x)=|x+2|+1\)

Step-by-step explanation:

Graph of a Modulus function:

Therefore, the parent function is:

\(\boxed{f(x)=|x|}\)

(Shown in red on the given graph).

From inspection of the given graph, the blue graph is the translated function.  As the left and right parts of the translated function are parallel to the left and right parts of the parent function, the graph has not been stretched and has only be translated (shifted).

To find the translation, study the vertex of both functions.  The vertex has been translated 2 units left and 1 unit up.

Translations

\(\textsf{For $a > 0$}:\)

\(f(x+a) \implies f(x) \: \textsf{translated $a$ units left}\)

\(f(x-a) \implies f(x) \: \textsf{translated $a$ units right}\)

\(f(x)+a \implies f(x) \: \textsf{translated $a$ units up}\)

\(f(x)-a \implies f(x) \: \textsf{translated $a$ units down}\)

Therefore, the equation for the translated function is:

\(f(x+2)+1 \implies \boxed{ g(x)=|x+2|+1}\)

The required probability is 0.970 (approx.) or 97/100 (in fraction).

Given that 69% of people in a large population have been vaccinated. We are required to determine the probability of at least one person being vaccinated if three people are randomly selected. Let's solve it using the complement rule.

The complement rule states that the probability of an event occurring is equal to 1 minus the probability of that event not occurring. That is, if A is an event, then P(A) = 1 - P(A').

We can solve the given problem using the complement rule as follows: Let P(A) be the probability of at least one person being vaccinated.

Then, the probability of no one being vaccinated is P(A') = (100 - 69) = 31%.

To find the probability of at least one person being vaccinated, we can subtract the probability of none of them being vaccinated from 1. That is, P(A) = 1 - P(A') = 1 - 0.31 × 0.31 × 0.31 = 1 - 0.029791 = 0.97021.

Hence, the probability of at least one person being vaccinated if three people are randomly selected is 0.97021 (rounded to 3 decimal places).

Therefore, the required probability is 0.970 (approx.) or 97/100 (in fraction).

x = 1 and x = 3

Step-by-step explanation:

Move 8x over to get the equation 2x² - 8x +6 = 0

Then factor to get (2x - 2)(x - 3)

Set both factors equal to zero and solve

2x - 2 = 0

2x = 2

x = 1

x - 3 = 0

x = 3

After solving the equations, we know that a total of 25 ladies attended the party.

A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation.

As in 3x + 5 Equals 15, for instance.

Equations come in a variety of forms, including linear, quadratic, cubic, and others.

So, take dudes as x and ladies as y.

Now, form the required 2 equations as follows:
2x + y = 45 ...(1)

x + y = 35 ...(2)

Work on equation (2):

x + y = 35

x = 35 - y

Now, substitute x = 35 - y in equation (1):

2x + y = 45

2(35-y) + y = 45

70 - 2y + y = 45

-y = -25

y = 25

Since ladies were charged $1 for each ticket, then 25 ladies attended the party.

Therefore, after solving the equations, we know that a total of 25 ladies attended the party.

Step-by-step explanation:

A: If there are 2 modes, x can be either 1 or 2.

B: To find the mode of the data set, we need to count how many times each number appears.

- 0 appears 2 times

- 1 appears 4 times

- 2 appears 4 times

- 3 appears 3 times

- 4 appears 1 time

Since both 1 and 2 appear 4 times in the data set, there are two modes.

For x, if we add it to the data set, then the mode must be x plus either 1 or 2.

If we choose x to be 2, then the mode would be 2, since 1 and 2 each appear 4 times, and adding another 2 would make it the mode.

So a possible value for x could be 2, and the mode would be 2.

What is the quadratic equation?

The solutions to the quadratic equation are the values of the unknown variable x, which satisfy the equation. These solutions are called roots or zeros of quadratic equations. The roots of any polynomial are the solutions for the given equation.

To find S(k) - T(k), we first need to find the expressions for S(k) and T(k):

S(k) = k² + k + 4

T(k) = k - 6

So, S(k) - T(k) = (k² + k + 4) - (k - 6)

= k² + k + 4 - k + 6 (distributing the negative sign)

= k² + 2k + 10

Therefore, S(k) - T(k) = k² + 2k + 10.

To find (f.g)(2), we first need to find the expression for f.g:

f.g(x) = f(g(x)) = f(x + 3) = (x + 3) - 3 = x

So, (f.g)(2) = f(g(2)) = f(2 + 3) = f(5) = 5 - 3 = 2.

Therefore, (f.g)(2) = 2.

Hence, the value of the question are:

So, we have

Answer:

Perimeter = \((30-\frac{3}{2}x)\)

Step-by-step explanation:

Width of the rectangle has been given as \((5-\frac{1}{4}x)\).

Convert the statement into the algebraic expression,

"Length of the rectangle is twice the width"

Length = 2(Width)

            = \(2(5-\frac{1}{4}x)\)

            = \(10-\frac{1}{2}x\)

Since perimeter of a rectangle is given by the expression,

Perimeter = 2(Length + Width)

By substituting the values of length and width in the expression,

Perimeter = \(2[(5-\frac{1}{4}x)+(10-\frac{1}{2}x)]\)

                 = \(2(15-\frac{3}{4}x)\)

                 = \((30-\frac{3}{2}x)\)

Therefore, expression representing perimeter is \((30-\frac{3}{2}x)\).

The probability that a randomly selected student will like pizza but not chicken nuggets is (28n - 8)/(28n + 7), where 28n is the students who like pizza and 8 is students who like both pizza and chicken nuggets.

To find the probability that a randomly selected student will like pizza but not chicken nuggets.

Let P = the number of students who like pizza but not chicken nuggets

Then, P = the number of students who like pizza - the number of students who like both pizza and chicken nuggets

P = 28n - 8

So, the probability that a randomly selected student will like pizza but not chicken nuggets is:

P(Pizza but not nuggets) = P/(Total number of students)

We can find the total number of students who like either pizza or chicken nuggets by adding the number of students who like pizza and the number of students who like chicken nuggets, and then subtracting the number of students who like both:

Total number of students = 28n + 15 - 8 = 28n + 7

So, the probability that a randomly selected student will like pizza but not chicken nuggets is:

P(Pizza but not nuggets) = P/(Total number of students) = (28n - 8)/(28n + 7)
