The 100 km difference between the two cities takes two trains to pass each other in 5 hours.

What do time, distance, and speed mean?

The relationship between speed, distance, and time is described using the formula of speed, distance and time.

That is speed = distance/time.

What is relative speed?

The velocity of an object in relation to another observer is referred to as the relative speed.

Given:

Atrain departs from city A and moves toward city B at a constant speed of 60 km/h and time taken is 8 hours.

At the same time, a second train departs city B and heads toward city A at a constant speed of 40 km/h.

The relative speed of first train with respect to the second train = 60-40

= 20 km/h

It is given that the two cities A and B are located 100 kilometers apart from one another.

So, distance between both cities = 100 km

By using the speed formula,

Speed = Distance/Time

Time = Distance/Speed

Time = 100/20

∴ Time = 5 hours

Consequently, it takes 5 hours for the two trains to pass one another with 100 km distance between two cities.

If your train travels at 65 miles per hour for 3.5 hours, it go 227.5 miles.

What is Speed ?

Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path. In other words, velocity is a vector, whereas speed is a scalar value.

Given:

Speed S = 65 miles per hour

Time T = 3.5 hours

We know that,

S= D/T Where D is the distance traveled.

Therefore,

65 miles per hour = D/ 3.5 hours

D = 65 x 3.5 miles

=227.5 miles

When counting the number of successes in n trials, the (D) binomial distribution should be used if the success probability, p, stays constant from trial to trial.

What is binomial distribution?When each trial has the same probability of achieving a given value, the number of trials or observations is summarized using the binomial distribution. The probability of observing a specific number of successful outcomes in a specific number of trials is determined by the binomial distribution. When counting the number of successes in n trials, the binomial distribution should be used if the success probability p stays constant.For the trials we are looking at, the probability of receiving success in a binomial distribution must stay constant. Since there are only two possible outcomes when tossing a coin, for instance, the probability of flipping a coin is 12 or 0.5 for each trial we conduct.

As it is given in the descrip[tion itself that the probability of observing a specific number of successful outcomes in a specific number of trials is determined by the binomial distribution.

When counting the number of successes in n trials, the binomial distribution should be used if the success probability p stays constant.

Therefore, when counting the number of successes in n trials, the (D) binomial distribution should be used if the success probability, p, stays constant from trial to trial.

Answer:

(1, - 2 )

Step-by-step explanation:

7x - 3y = 13 → (1)

9x + 10y = - 11 → (2)

multiplying (1) by 10 and (2) by 3 and adding will eliminate y

70x - 30y = 130 → (3)

27x + 30y = - 33 → (4)

add (3) and (4) term by term to eliminate y

97x + 0 = 97

97x = 97 ( divide both sides by 97 )

x = 1

substitute x = 1 into either of the 2 equations and solve for y

substituting into (2)

9(1) + 10y = - 11

9 + 10y = - 11 ( subtract 9 from both sides )

10y = - 20 ( divide both sides by 10 )

y = - 2

solution is (1, - 2 )

How to find corresponding angles?

When two parallel lines are intersected by a third one, the angles that occupy the same relative position at each intersection are known to be corresponding angles to each other.

1) From definition of corresponding angles, line m is parallel to line n and as such, we can say that;

After a dilation with a scale factor of 2.5 and center of dilation (0, 0), the coordinates of the vertices of triangle A'B'C' are A' (-5, -2.5), B' (2.5, 5), and C' (5, -10).

What is dilation?

Dilation simply refers to a type of transformation which changes the size of a geometric object, but not its shape. This ultimately implies that, the size of the geometric object would be increased or decreased based on the scale factor used.

What is scale factor?

A scale factor can be defined as the ratio of two (2) corresponding length of sides or diameter in two similar geometric figures such as triangles.

For the given coordinates, the dilation with a scale factor of 2.5 and center of dilation (0, 0) should be calculated as follows:

Point A (-2, -1) → Point A' (-2 × 2.5, -1 × 2.5) = Point A' (-5, -2.5).

Point B (1, 2) → Point B' (1 × 2.5, 2 × 2.5) = Point B' (2.5, 5).

Point C (2, -4) → Point C' (2 × 2.5, -4 × 2.5) = Point C' (5, -10).

Answer:

(5,0)

Step-by-step explanation:

Let y=0. Then, x=5.

Line A is perpendicular to D because a is parallel to c and c is perpendicular to d.

How are parallel straight lines related?

Parallel lines have the same slope since the slope is like a measure of steepness and since parallel lines are of the same steepness, thus, are of the same slope. Since the given parallel line has equation y = 2x + 2, thus its slope is 2 and thus, the slope of the needed line is 2 too.

WE have been given that a ll b,b ll c,c is perpendicular to d.

Here the line a is parallel to b and b is parallel to c so a must be parallel to c.

As we know that c is perpendicular to d since, a is parallel to c.

Therefore, Line A is perpendicular to D because a is parallel to c and c is perpendicular to d.

How to Determine the Variability and Mean of a Data Set?

To find the mean of a data set, sum all data points given together and divide what you get by the number of data points that is given in the data set.

The range of a data gives us an idea of the spread of a data, which is a measure of variability. The larger the range, the more the variability that exist in the data set.

Given, Group A: 51, 53, 60, 64, 55, and Group B: 50, 55, 58, 63, 52, find the mean of each data set

Mean for Group A = (51 + 53 + 60 + 64 + 55)/5 = 283/5 = 56.6

Mean for Group B = (50 + 55 + 58 + 63 + 52)/5 = 278/5 = 55.6

Range for Group A = 64 - 51 = 13

Range for Group B = 63 - 50 = 13

What is a regular polygon?

A two-dimensional geometric shape with a finite number of sides is called a polygon. A polygon's sides or edges are made up of segments of straight lines that are joined end to end to create a closed shape.

The intersection of two lines is referred to as a vertex or corner, and an angle is created as a result. Regular polygons are those that have sides that are congruent.

We will use the side-angle relation of a regular polygon with any no. of sides to find total sum of interior angles that is
