Line AB and CD are two parallel lines

The slope of a line is defined as the change in y- the coordinate with respect to the x-coordinate and the formula is given by    

Note:

Here we have  

AB formed by (-4, 7) and (-2, 6)

Slope of AB = (6 - 7)/(-2 + 4) = -1/2

CD formed by (2, -2) and (-8, 3)

Slope of CD = (3 + 2)/(-8 - 2) = 5/-10 = -1/2

Here Slope of AB = Slope of CD  

As we know the slope of parallel lines is equal

The percentage of vehicles whose speeds are between 52 miles per hour and 70 miles per hour is 75%.

A statistical principle known as the empirical rule, also known as the three-sigma rule or 68-95-99.7 rule, holds that with a normal distribution, almost all observed data will fall within three standard deviations of the mean.

Given, The mean speed of a sample of vehicles along a stretch of highway is 64 miles per​ hour, with a standard deviation of 4 miles per hour.

[tex]\mu = 64[/tex] and [tex]\sigma = 4[/tex].

Now, 52 is 3 standard deviations away from the mean so 50% of the data falls into this category and 70 is 1.5 standard deviations away from the mean and 25% of the data falls into this category.

Therefore, 75% of the vehicles would fall into this category.

The statement “Every sample space S is a finite set” is false because some sample spaces can be infinite, such as rolling a continuous random variable.

The statement “Every sample space S is a finite set” is false. A sample space is the set of all possible outcomes of a random experiment. While some sample spaces may be finite, not all sample spaces are. There are situations where the sample space can be infinite, such as when rolling a continuous random variable like a dice.

For example, the sample space of rolling a fair six-sided die is finite, consisting of the numbers {1, 2, 3, 4, 5, 6}. However, the sample space of choosing a real number between 0 and 1 is infinite, as there are infinitely many possible outcomes between 0 and 1.

Therefore, it is incorrect to say that every sample space is a finite set.

The possible numbers of players are multiples of 6 (6, 12, 18, etc.).

Step-by-step explanation:

For the coach to be able to form teams of 6 players each, the total number of players must be divisible by 6. This means that if there are 6, 12, 18, 24, 30, etc. players, the coach can divide them evenly into teams of 6. Any other number of players would result in either having a team with more or fewer than 6 players, or leaving some players out. Hence, the possible numbers of players are multiples of 6.

The function which models the data as represented on the graph will be; [tex]f(x) = 0.8(1/2)^x[/tex].

Function is a type of relation, or rule, that maps one input to specific single output.

In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.

The given graph is an exponential function and should take the form;

[tex]f (x) = a (b)^x[/tex]

Hence, using values from the graph;

For ( -1, 0.2 ) = a • b..........(i)

For (0, 0.8); 10.5 = a • b².........(ii)

To find the equation of the line passing through the point (8, -2) that is perpendicular to the line y = 4/5x + 4, we can use the concept of the slope of a line. The slope of a line perpendicular to another line has a negative reciprocal slope.

The slope of the line y = 4/5x + 4 is 4/5. The negative reciprocal of 4/5 is -5/4.

So, the slope of the line passing through (8, -2) and perpendicular to y = 4/5x + 4 is -5/4.

Next, we can use the point-slope form of a line to find the equation of the line:

y - y1 = m(x - x1), where m is the slope and (x1, y1) is the given point.

Substituting the values, we get:

y - (-2) = -5/4 (x - 8)

Expanding and solving for y, we get:

y = -5/4x + 26/2

y = -5/4x + 13

The equation of the line passing through the point (8, -2) that is perpendicular to the line y = 4/5x + 4 is y = -5/4x + 13.

Let's call the time it took Pat and Rich to drive to the beach "x".

The time it took them to drive back was twice as long, so it took 2x hours.

The total time spent traveling was x + 2x = 3x hours.

Since they spent 9 hours traveling, 3x = 9 hours.

So, x = 9 hours / 3 = 3 hours.

This means it took Pat and Rich 3 hours to drive to the beach and 2 * 3 = 6 hours to drive back.

The required amount invested in accounts with 8% and 12% are $1470 and $1820 respectively.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
Lydia has money in two savings accounts one rate is 8% and the other is 12%  and the total interest is $336. Let the amount invest in accounts be x and y respectively.
According to the question,
0.08x + 0.12y = 336 - - - - - -(1)

Again,
she has $350 more in 12% account
y = x + 350 - - - - - -(2)

Put y in equation 1,
0.08x + 0.12[x + 350] =336
0.08x + 0.12x + 42 = 336
0.20x = 336 - 42
x = 294/0.20

The rate of change of the hypotenuse is given as follows:

dh/dt = 2 in/sec.

The Pythagorean Theorem states that for a right triangle, the length of the hypotenuse squared is equals to the sum of the squared lengths of the sides of the triangle.

The hypotenuse is then given as follows:

h² = x² + y².

For this problem, the hypotenuse has the value given as follows:

h² = 33² + 44²

h = square root(33² + 44²)

h = 55.

Applying implicit differentiation, the rate of change of the hypotenuse is obtained by the equation as follows:

h dh/dt = x dx/dt + y dy/dt.

Replacing the values, the rate of change is calculated as follows:

55dh/dt = 33 x 10 - 44 x 10

55dh/dt = -110

dh/dt = -110/55

In which k is the constant of proportionality.

For an inverse relation, the relation is modeled as follows:

y = k/x.

Meaning that when x increases, y decreases at a constant rate.

The constant is then obtained as follows:
