A employee must create 140 gallons of slash burn fuel that must have a ratio of 8 parts diesel to 2 parts gas. How much diesel and gas are needed to create this mixture?
The amount of diesel required to create slash burn fuel is = 112 gallons
The amount of gas required to create slash burn fuel = 28 gallons
What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
Given data ,
The total amount of slash fuel = 140 gallons
The ratio of diesel to gas in slash fuel is = 8 : 2
Let the amount of diesel required to create slash burn fuel be = 8x
Let the amount of gas required to create slash burn fuel be = 2x
So , the equation of proportion is given by
Total amount of slash fuel = amount of diesel required to create slash burn fuel + amount of gas required to create slash burn fuel
Substituting the values in the equation , we get
Total amount of slash fuel = 8x + 2x
8x + 2x = 140
10x = 140
Divide by 10 on both sides of the equation , we get
x = 14 gallons
Substituting the value of x in the above expressions , we get
Amount of diesel required to create slash burn fuel = 8x
Amount of diesel required to create slash burn fuel = 8 x 14
Amount of diesel required to create slash burn fuel = 112 gallons
And ,
Amount of gas required to create slash burn fuel = 2x
Amount of gas required to create slash burn fuel = 2 x 14
Amount of gas required to create slash burn fuel = 28 gallons
Hence ,
The amount of diesel required to create slash burn fuel is = 112 gallons
The amount of gas required to create slash burn fuel = 28 gallons

Answer:
Rule 2: To win you a basic prize, you need to spin an "A" or a "1". What is the probability that you win a basic prize?
Probability of winning a grand prize is 1/10
Probability of winning a basic prize is 11/20
What is the probability of two independent events?
If A and B are two independent events, then P(A and B) = P(A) * P(B).
If Events A and B are independent, the probability that either Event A or Event B occurs is: P(A or B) = P(A) + P(B) - P(A and B).
Solution:
P(A) = no. of A / total possibility
= 4/10
P(B) = no. of 1's/total possibility
= 3/12
= 1/4
Now,
To win a grand prize you need an "A" and "1" .
∴ P(A and B) = P(A) × P(B)
= 4/10 × 1/4
P(A and B) = 1/10
Now ,
To win a basic prize you need to spin an "A" or a "1"
∴ P(A or B) = P(A) + P(B) - P(A and B)
= 4/10 + 1/4 - 1/10
= 3/10 + 1/4

An equation for the line in slope-intercept form is y=(6/5)x+8
What is a slope?The same number is given for every two different points on the same line when the ratio is stated as a quotient ("rise over run"). On a falling line, there is a negative "rise." In a diagram that depicts a roof or a road as a description or a design, the line may be practical as established by a road surveyor.
The steepness, incline, or grade of a line can be approximated by the slope's absolute value. The slope of a line determines how steep it is.
From the graph,
The line passes through the points (0,8) and (5, 14)
Slope m=(14-8)/(5-0)
m=6/5
(0, 8) passes through the line y=mx+c

The above expression can be solved using the law of indices
When the law of indices is applied, we have the following representation
2³/2⁷ = 2(³ ⁻ ⁷)
Remove the bracket in the above expression
So, we have the following representation
2³/2⁷ = 2³ ⁻ ⁷
Evaluate the difference
This gives
2³/2⁷ = 2⁻⁴

How do you define numerical and univariate?If the collection of all potential values for a numerical univariate data is finite or countably infinite, the data is discrete. Usually, discrete univariate data are used in counting (such as the number of books read by a person). If the range of all potential values is a set of numbers, then a numerical univariate data is continuous.
Categorical data – what is it?Categorical variables represent different sorts of data that may be categorized. Race, sex, age group, and educational level are some examples of categorical variables.
Data types that may be kept and recognized based on the names or labels assigned to them are referred to as categorical data.

What is elimination method ?Using the elimination method, you may either add or subtract the equations to produce an equation in one variable. To eliminate a variable, add the equations when the coefficients of one variable are in opposition, and subtract the equations when the coefficients of one variable are in equality.
According to the given information
Let number of drinks = x
Let number of candies = y
Christian bought 8 drinks and 10 candies and it costed $94
So the equation becomes
8x + 10 y = $94
Other guy bought 9 drinks and 6 candies and it costed $79.50
So the equation becomes
9x + 6y = $79.50
By applying elimination method
9x + 6y = $79.50
Dividing by 2
3x + 2y = $26.5
multiplying the above equation by 5
15x + 10y = $132.5
8x + 10 y = $94
Subtract the following equation
7x = 38.5

The coordinates point C of the given line segment AC is C(0, -2) whose midpoint is at B.
How to calculate a midpoint of a line segment?To calculate the midpoint of a line segment, find the average for the coordinates of the endpoints of the line segment. I.e.,
Consider a line segment AC, B is its midpoint.
So, the coordinates of B are (Where we have A(x1, y1) and C(x2, y2))
B(x, y) = [tex](\frac{x1+x2}{2}, \frac{y1+y2}{2})[/tex]
Calculation:It is given that, B is the midpoint of a line segment AC.
Where A has coordinates as (-3, 4) and B has coordinates as (-1 1/2, 1).
So, the coordinates of the other end point C of the given line segment are calculated as
B(x, y) = [tex](\frac{x1+x2}{2}, \frac{y1+y2}{2})[/tex]
⇒ (-1.5, 1) = [tex](\frac{-3+x2}{2}, \frac{4+y2}{2})[/tex]
⇒ -1.5 = (-3 + x2)/2 and 1 = (4 + y2)/2
⇒ -3 = -3 + x2 and 2 = 4 + y2
⇒ x2 = 0 and y2 = 2 - 4 = -2
Therefore, point C has coordinates as (0, -2).

The equation of a line that is parallel to -x + 3y = 6 and passes through the point (3,5) is y = 1 / 3 x + 5
How to find the equation of a line?The equation of a line can be represented in slope intercept form as follows:

where
m = slopeb = y-interceptTherefore, the equation of a line that is parallel to -x + 3y = 6 and passes through the point (3,5) can be found as follows:
Parallel lines have the same slope.
-x + 3y = 6
3y = x + 6
y = 1 / 3 x + 2
Therefore, the slope is 1 / 3. Let's find the y-intercept using (3, 5).

n is the number of trials of the experiment.p is the probability of a success on a single trial of the experiment.For item a, considering that for 50 questions, all are guessed among five answer, the values of these parameters are given as follows:
n = 50, p = 1/5 = 0.2.
The probability of passing is given as follows:
P(X ≥ 35).
Using a binomial distribution calculator, with the given parameters, we have that:
P(X ≥ 35) = 0%.
For item b, the parameters are given as follows:
n = 25, p = 1/4 = 0.2.
Hence the probability of a perfect score is given as follows:
P(X = 25) = 0.2^25 = 3.35 x 10^-18.
For item c, we have that the first version is safer against examinees guessing to achieve a passing score, as:

A standard queen bed hotel room at the Posh Inn is currently priced at $ 135 a day, after a 17 % markup to offset inflation costs. What was the daily charge for the room before the increase?
the regular daily charge is "x", oddly enough that's the 100%.
so the new charge is 17% up, that means the new charge is 100% + 17% = 117%, and we know that's $135, so
[tex]\begin{array}{ccll} amount&\%\\ \cline{1-2} x & 100\\ 135& 117 \end{array} \implies \cfrac{x}{135}~~=~~\cfrac{100}{117} \\\\\\ 117x=13500\implies x=\cfrac{13500}{117}\implies x=\cfrac{1500}{13}\implies x=115\frac{5}{13}[/tex]
