An equation that can can be used to find the number of sales Luke made this week is; 191 + 16.55x = ¹/₃(573 + 49.65x)
How to Solve Equation Word Problems?
We are told to represent the number of sales as x.
Now, Luke works at a store and earns a fixed amount of $191 plus $16.55 per sale. This is represented as; 191 + 16.55x
Noah works at a different store and earns a fixed amount of $573 plus $49.65 per sale. This is represented as; 573 + 49.65x
We are told that they both made the same number of sales but Luke earned a third of what Noah earned. Thus;
191 + 16.55x = ¹/₃(573 + 49.65x)
An equation that can can be used to find the number of sales Luke made this week is;
191 + 16.55x = ¹/₃(573 + 49.65x)

-1.96312.. is a real, irrational number while √(-5) is imaginary. There is no value for a root of a negative number
Step-by-step explanation:
You should understand that numbers are naturally classified as real and imaginary. Under the real numbers, they are additionally classified into rational and irrational numbers. Under rational numbers, these possess fractions and integers. Irrational numbers are in decimal forms that cannot be converted to fractions. Thus, the difference between the two is that: -1.96312.. is a real, irrational number while √(-5) is imaginary. There is no value for a root of a negative number.

•Si x = 2 metros, ¿cuál es el perímetro del terreno?
El área del terreno es igual a 406 metros cuadrados.
El perímetro del terreno es igual a 104 metros.
¿Cuál es el área y el perímetro de un terreno?
En esta pregunta tenemos conocimiento de las ecuaciones asociadas a las longitudes de la base y la altura del terreno, cuya forma es rectangular. Inicialmente, determinamos el área del terreno:
A = b · h
A = (20 - 2 · x) · (16 + 10 · x)
A = (20 - 2 · 3) · (16 + 10 · 3)
A = (20 - 6) · (16 + 13)
A = 14 · 29
A = 406 m²
El área del terreno es igual a 406 metros cuadrados.
Ahora, determinamos el perímetro del terreno:
p = 2 · (b + h)
p = 2 · [(20 - 2 · x) + (16 + 10 · x)]
p = 2 · (8 · x + 36)
p = 16 · x + 72
p = 16 · 2 + 72
p = 32 + 72
p = 104 m

What is counting theorem?The basic counting principle is a method for keeping track of all the potential outcomes in a situation. According to this statement, there are n m n times m n methods to carry out both of these acts if there are n ways to execute one activity and m ways to perform another action after that.Now, by the counting principle,

If Harold and Ulysses both paint picket 7, Ulysses is unable to paint picket 5, so Tanya does. The picket is painted by Ulysses, and (h, t, u) = (3, 3, 3). However, let's say Tanya paints picket 4. Harold paints picket 5 since Ulysses is unable to do so or then there won't be anything left to paint. Ulysses paints picket 7 as a result, and (h, t, u) = (4, 2, 4).Hence, the possible triples are: (3, 3, 3), (4, 2, 4).

the degree of correlation among independent variables in a regression model is called . a. multicollinearity b. the coefficient of determination c. interaction d. the sum of squared errors (sse)
Multicollinearity refers to the degree of correlation among independent variables in a regression model.
What is Multicollinearity?In a multiple regression model, one predictor variable can be predicted linearly from the others using a high degree of accuracy when there is a phenomenon known as multicollinearity (also known as collinearity). In this case, minor adjustments to the model or the data may cause the multiple regression's coefficient estimates to fluctuate unpredictably. Multicollinearity only impacts calculations pertaining to specific predictors; it has no impact on the predictive capability or reliability of the model as a whole, at least within the sample data set. In other words, a multivariate regression model with collinear predictors can show how well the complete set of predictors predicts the outcome variable, but it could not provide accurate information about any particular predictor or which predictors are redundant in relation to others.

Solve the following system of equations.
5 a-b=17
3 a+2 b=5
Answer:
a = 3 , b = - 2
Step-by-step explanation:
5a + b = 17 → (1)
3a + 2b = 5 → (2)
multiplying (1) by 2 and adding to (2) will eliminate b
10a + 2b = 34 → (3)
add (2) and (3) term by term to eliminate b
13a + 0 = 39
13a = 39 ( divide both sides by 13 )
a = 3
substitute a = 3 into either of the 2 equations and solve for b
substituting into (1)
5(3) + b = 17
15 - b = 17 ( subtract 15 from both sides )
- b = 2 ( multiply both sides by - 1 )
b = - 2
then solution is a = 3 , b = - 2

Using scientific notation, it is found that:
The number is written as follows: [tex]9.821 \times 10^2[/tex] m².The number has 4 significant digits, which are 9, 8, 2 and 1.What is scientific notation?A number in scientific notation is given by:
[tex]a \times 10^b[/tex]
With the base being [tex]a \in [1, 10)[/tex].
For this problem, the number is given by:
982.1 m².
In scientific notation, the base has to be a number between 1 and 10(open interval at 10), hence the base has to be divided by 100.
To compensate for the division by 100, the number has to be multiplied by 100 somewhere, which happens when we add 2 to the exponent, as 10² = 100.
Hence:
The number is written as follows: [tex]9.821 \times 10^2[/tex] m².
The significant digits are all the digits that are not zero, and the zeros at the beginning or between other numbers, hence they are:
9, 8, 2 and 1.
Meaning that the number has 4 significant digits.

How to calculate the number of miles in the taxi ride ?The taxi company was charged a pick-up fee of $3.10
It also charges $2.75 per mile
The total fare is $27.85
The equation can be written as
2.75x + 3.10 = 27.85
Collect the like terms to get the value of x
2.75x= 27.85 - 3.10
2.75x = 24.75
divide both sides by the coefficient of x which is 2.75
2.75x/2.75= 24.75/2.75

We wish to test the hypothesis that the mean weight of a population of fish is 140g. With sigma=15 g and alpha= 0.05, and a sample of 36 fish, find a) the mean values which would lead to a rejection of the hypothesis and Use a two-tailed test.
Using the z-distribution, it is found that mean weights less than 135.1g and more than 144.9 would lead to a rejection of the hypothesis.
What is the critical value of the test?We have a two-tailed test, with a significance value of α = 0.05, hence, using a z-distribution calculator, the critical value is given by:
|z| = 1.96 -> z < -1.96 or z > 1.96.
What is the test statistic?The test statistic is given as follows:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which:
X is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.[tex]\sigma[/tex] is the standard deviation of the population.n is the sample size.For this problem, the parameters are given as follows:
[tex]\mu = 140, \sigma = 15, n = 36[/tex]
The lower bound of acception is found as X when z = -1.96, hence:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
-1.96 = (X - 140)/(15/6)
-1.96 = (X - 140)/(2.5)
X - 140 = -1.96 x 2.5
X = 135.1.
The upper bound of acception is found as X when z = 1.96, hence:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
1.96 = (X - 140)/(15/6)
1.96 = (X - 140)/(2.5)
X - 140 = 1.96 x 2.5
X = 144.9.
Hence:
Mean weights less than 135.1g and more than 144.9 would lead to a rejection of the hypothesis.

and the price of an individual can = $2
Now, if I want to purchase at least 25 individual cans there can be two possible ways to do this:
I Purchase 2 packages of the can and then purchase the rest individual cans. Thus, if I have to purchase 25 cans it will cost around: 14 × 2 + 5 × 2 = $38.I Purchase 3 packages of cans.
