How do you know the value of x is positive?

Considering the definition of an equation and the way to solve it, the number of miles in a day at which the rental costs for Company A and Company B are the same is 200.

An equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear.

The members of an equation are each of the expressions that appear on both sides of the equal sign.

The solution of a equation means determining the value that satisfies it. To solve an equation, keep in mind:

First, you define the variable "m" as the number of miles rented from a truck to a company in a day. You know that:

So the price of each company is:

If the rental costs for Company A and Company B are the same, the equation in this case is:

Price of company A= Price of company B

130 + 0.30m= 70 + 0.60m

Solving:

130 - 70= 0.60m - 0.30m

60= 0.30m

60÷0.30= m

200= m

In summary, the number of miles in a day at which the rental costs for Company A and Company B are the same is 200.

Step-by-step explanation:

The y-intercept is -5 so the line hits the y-axis at -5. The slope of the line is 1/2 so the line goes up one and to the right two each time.

The numbers from least to greatest are -

square root of 7, 2.8, square root of 7 and 4.6.

Descending pattern is defined as it is when numbers (and other objects) are arranged in descending order from the largest to the smallest numbers.

Ascending is defined like when numbers (or even other items) are positioned in ascending order from the smallest to the largest numbers.

We have the numbers provided as;

4.6, 2.8, square root of 17 and the square root of 7.

Then,

square root of 7

√7 = 2.645, and

square root of 17

√17 = 4.123

Thus, the given series becomes;

4.6, 2.8, 4.123, 2.645.

Now, arranging them according to ascending order (least to greatest).

2.645, 4.123, 2.8 and 4.6.

Therefore, the series becomes; square root of 7, 2.8, square root of 7 and 4.6.

The polynomial expression for the profit from making and selling x model kits is 28x - 500,000 - 0.00005 x² and the profit is 3400000.

Polynomial is the combination of variables and constants systematically with "n" number of power in ascending or descending order.

[tex]\rm a_1x+a_2x^2+a_3x^3+a_4x^4..........a_nx^n[/tex]

It is given that:

Suppose the cost in dollars of producing x model kits is given by the polynomial 500,000 + 2x and the revenue generated from sales is given by the polynomial 30x - 0.00005 x².

The profit = revenue - cost

The profit = (30x - 0.00005 x²) - (500,000 + 2x)

The profit = 30x - 0.00005 x² - 500,000 - 2x

The profit = 28x - 500,000 - 0.00005 x²

Plug x = 300,000 in the profit expression.

The profit = 3400000

Thus, the polynomial expression for the profit from making and selling x model kits is 28x - 500,000 - 0.00005 x² and the profit is 3400000.

Step-by-step explanation:

The claim that a researcher may infer a causal link between variables if one effects another is False.

If a change in one variable's level results in a change in the other variable, then there is a causal relationship between the two variables. Keep in mind that correlation does not always imply causation. Two variables may be linked together without one of them directly contributing to the other's observable behavior.

For instance,

the chart below illustrates the relationship between ice cream sales and temperature. Any business can utilize the concept of causality. As is clear from the graph, there is a correlation between warmer weather and increased sales.

A casual relationship between two variables only exists when one of the variables actually causes the other to exist, which does not appear to be the case here. Instead, since a change in one variable affects the other, this scenario can be thought of as a correlated relationship.

After converting all the given units of length into meters we get,

[tex]108 in = 2.7432 m\\108 ft = 32.9184 m\\12 ft = 3.6576m\\1 yd= 0.9144m[/tex]

As per the question statement, we are supposed to convert these given units of length into meters i.e., 108 inches, 108 feet, 12 feet, 1 yard.

We know

The lengths of the three sides of the triangular lot are: 100 feet, 200 feet and 400 feet.

What is a triangle and its perimeter?

A triangle is a polygon with three edges and three vertices.

Given:

To find: All the sides of the triangular lot.

FInding:

Let the shortest side of the triangular lot be 'x'.

Then, according to the question, one side of the triangular lot = 100 + x and other = 300 + x

As perimeter of a triangle = sum of all the sides,

=> 1300 = x + 100 + x + 300 + x

=> 1300 - 400 = 3x

=> 900 = 3x

=> 300 = x

Hence, the shortest side = 100 feet, a longer side = 200 feet, the longest side = 400 feet for the given triangular lot.

The formula for calculating the probability of one success under certain conditions is:

x=0.4.

"The ratio of the number of favorable outcomes to the total number of outcomes is the standard mathematical definition of probability. Probability is never more than one, and it is never equal to that number."

Generally, the equation for Probability is  mathematically given as

Probability [tex]$={ }^n C_r p^r q^{n-r}$[/tex]

According to the question,

Total number of trials n'=4

Number of successes r =1

p=0.35

q=1-0.35

q=0.65

Simply replace the value in order to calculate the appropriate probability.

[tex]\text { Probability } &={ }^4 C_1(0.35)^1(0.65)^{4-1} \\[/tex]

[tex]&=\frac{4 !}{(4-1) ! 1 !} \times \frac{35}{100} \times\left(\frac{65}{100}\right)^3 \\[/tex]

[tex]&=4 \times \frac{35}{100} \times \frac{274625}{1000000} \\[/tex]

=0.384475
