the cost , where is the number of miles driven, of renting a car for a day is $42 plus $0.65 per mile. what is the slope of the linear function and its units?

The solution to the system of linear equations is (x, y) = (- 8 / 5, 6 / 5).

In this problem we need to build and solve a system of two linear equations with two variables. Linear equations are expression of the form:

y = m · x + b

Where:

And the slope is calculated by following formula:

m = Δy / Δx

First, determine the linear equations associated with each table:

First line - Slope

m = (- 2 - 0) / [- 1 - (- 2)]

m = - 2 / 1

m = - 2

First line - Intercept

b = y - m · x

b = 0 - (- 2) · (- 1)

b = - 2

y = - 2 · x - 2

Second line - Slope

m = (3 - 1) / [2 - (- 2)]

m = 2 / 4

m = 1 / 2

Second line - Intercept

b = y - m · x

b = 3 - (1 / 2) · 2

b = 3 - 1

b = 2

y = (1 / 2) · x + 2

Second, find solution the system of linear equations:

Find x:

(1 / 2) · x + 2 = - 2 · x - 2

(5 / 2) · x = - 4

5 · x = - 8

x = - 8 / 5

Find y:

y = (1 / 2) · (- 8 / 5) + 2

y = 6 / 5

The system of linear equations has the following solution: (x, y) = (- 8 / 5, 6 / 5)

The probability of selecting exactly 2 white marbles out of 5 marbles from container b is approximately 0.144 or 14.4%.

To calculate the probability of selecting exactly 2 white marbles out of 5, we can use the binomial coefficient formula, which is given by:

P(X=k) = (n choose k) × [tex]p^{k}[/tex] × [tex]1-p^{n-k}[/tex]

where n is the total number of trials (in this case, 5), k is the number of successful outcomes (in this case, 2), p is the probability of success (in this case, the probability of selecting a white marble), and (n choose k) is the binomial coefficient.

First, let's find the probability of selecting a white marble from container B, which is given by:

p = (number of white marbles) / (total number of marbles) = (300 + 1) / (300 + 100 + 1) = 301 / 401

Next, we can use the formula to find the probability of selecting exactly 2 white marbles:

P(X=2) = (5 choose 2) × p² * (1-p)⁽⁵⁻²⁾ = (10) × (301/401)² × (100/401)³ = 0.144

So the probability of selecting exactly 2 white marbles out of 5 is approximately 0.144 or 14.4%.

There is no way to accurately answer this question as there are too many variables to consider, such as the population size and crime rate of the state.

There is no way to accurately answer this question as there are too many variables to consider. The population size of the state would be an important factor in calculating the number of murders per 100,000 residents. The population size of the state would determine how many people are in the state with an automatic weapon and therefore how many potential murders could occur. Additionally, the crime rate of the state would be an important factor in determining the number of murders per 100,000 residents as it would indicate whether or not there would be a higher propensity for crime in the state. Additionally, the availability of other weapons, such as handguns or knives, would also be a factor as it could reduce or increase the number of murders with automatic weapons. All of these factors, as well as others, make it impossible to accurately determine the number of murders per 100,000 residents in a state with 1 thousand automatic weapons.

Answer:

The answer is $99

Step-by-step explanation:

The total money Lincoln has to pay for his family to see a movie and share 4 snacks is $59. When Lincoln buys x snacks to share, the total cost would be $39 plus $5x.

The costs that Lincoln has to pay consists of two parts: the cost for the tickets and the cost for snacks. Lincoln himself and his two kids makes for 3 people in total. A ticket for each person costs $13, so the cost for tickets is 3 multiplied by $13, which equals $39.

If Lincoln buys 4 snacks for everybody to share, each at a price of $5, these snacks would cost 4 multiplied by $5, which is $20 in total. So, the total cost would be $39 (for tickets) plus $20 (for snacks), resulting in a total of $59.

For the case when Lincoln buys x snacks for everybody to share, just replace the number 4 with x in our snacks calculation. That would be $5x for the snacks cost. The total cost Lincoln would have to pay is then, still $39 for tickets, plus $5x for snacks.

There are 15 test scores that are 85 or greater out of a total of 30 test scores.

The third quartile, Q3, is the median of the upper half of the set of data. To determine the number of test scores that are 85 or greater, we must first find the median of the upper half of the data set. The formula to calculate the median is

Median = (n+1)/2

where n is the number of observations in the data set. In this case, n is 30. Plugging this into the formula we get

Median = (30+1)/2 = 15.5

Therefore, there are 15.5 test scores that are 85 or greater.

To calculate the number of test scores that are 85 or greater, we subtract 15.5 from 30. This gives us 14.5 test scores that are 85 or greater. Since 14.5 is not a whole number, we can round up to 15 test scores that are 85 or greater. Therefore, there are 15 test scores that are 85 or greater out of a total of 30 test scores.

The player would make or miss 10 shots.

The basketball player with a 50 percent shooting average would make or miss 10 baskets out of 21 shots taken. The pattern of makes and misses would be random, meaning there is no particular pattern for the player to follow. For example, we could see the following sequence of makes and misses: make, miss, make, make, miss, miss, make, miss, make, make, miss, make, make, miss, make, miss, make, miss, make, make, miss. We can calculate the expected outcomes of each shot by dividing the total number of shots (21) by the shooting average (50 percent). This gives us an expected outcome of 10.5, which is rounded to 10. Therefore, the player would make or miss 10 shots.

The value of x in this equation (x/2) - (2/x+1) = 1 is -2 and 3.

Two expressions are combined in an equation using an equal symbol ("="). The "left-hand side" and "right-hand side" of the equation are the two expressions on either side of the equals sign. Typically, we consider an equation's right side to be zero. Since we can balance this by deducting the right-side expression from both sides' expressions, this won't reduce the generality.

Given the equation is

(x/2) - (2/x+1) = 1

thaking LCM of left side of equation we get,

[x(x+1) - 2*2]/ 2(x+1) = 1

⇒ (x² + x - 4) / (2x +2) = 1

multiply both side by (2x +2) we get,

⇒ (x² + x - 4) = (2x +2)

subtract both side by (2x +2) we get,

⇒ (x² + x - 4) - (2x +2) = 0

⇒ x² - x - 6 = 0

to get the value of x we factorize this equation

⇒ x² - (3-2)x - 6 = 0

⇒ x² - 3x +2x - 6 = 0

⇒ x (x - 3) + 2 (x - 3) = 0

⇒ (x - 3) (x +2) = 0

from x+2 = 0, we get the value of x = -2

and from x-3 = 0, we get the value of x = 3,

So that the value of x in this equation (x/2) - (2/x+1) = 1 is -2 and 3.

If the store sells 80 feet of rope, it makes a profit of $6.4.

The money made from selling a product, which should be higher than its cost price, is referred to as the profit. It is the gain from any type of commercial activity. In other words, a gain or profit is judged to have occurred when the selling price (SP) of a product exceeds its cost price (CP).

Given the amount a hardware store pays for buying nylon rope is represented by the equation,

y = 0.12x

the cost price of rope is y = 0.12x

and the amount the hardware store charges when selling the rope is represented by the graph,

from graph,

we find the coordinates (1, 0.20) (2, 0.40)

the equation of a line is y = mx + c

since the graph passes from the origin (0, 0) so the equation of the graph will be,

y = mx

and  m = (.40 - 0.20)/(2 - 1)

m = 0.20

selling price of rope = y = 0.20x

where x is the length of rope in feet and y is the amount,

If the store sells 80 feet of rope,

the cost price of  80 feet of rope is

y = 0.12x

y = 0.12(80)

y = $9.6

and the selling price of 80 feet of rope is

y = 0.20x

y = 0.20(80)

y = $16

The required general solution of the differential equation in implicit form y = [tex][(3/2) * (15x + C) * x^{-3}]^{-3/2}[/tex].

The differential equation is a nonlinear equation and cannot be solved exactly by standard methods. One way to approach a solution is to try to find a substitution that transforms the equation into a separable form, where the variables can be separated and integrated separately. A common approach is to make the substitution y = v^(-2/3), which transforms the equation into:

3x^2 * (2/3) * v^(-5/3) * v' + 6x * v^(-2/3) = 15 * v^(-5/3)

Dividing both sides by v^(-5/3), we get:

3x^2 * (2/3) * v' + 6x * 3 * (2/3) * v^(1/3) = 15

This is now a separable differential equation, and we can integrate both sides to find the general solution:

∫(3x^2 * (2/3) * v' dx) = ∫(15 dx) + C

(2/3) * x^3 * v = 15x + C

v = (3/2) * (15x + C) * x^(-3)

Finally, substituting back for y = v^(-2/3), we get the general solution:

y = [tex][(3/2) * (15x + C) * x^{-3}]^{-3/2}[/tex]

This is the general solution of the differential equation in implicit form. To find an explicit form, one could solve for C using initial or boundary conditions.
