The time that Llyr arrives at Nuneaton, given that it is 6 minutes late, is 10 34.

Llyr's journey from Preston to Nuneaton took 114 minutes.

Kathy would not catch the 10 28 train to Milton Keynes.

Llyr is meant to arrive in Nuneaton at 10 28 but arrived 6 minutes later which is:

= 10 28 + 6

= 10 34

The time that the trip took is therefore:

= Arrival at Nuneaton - Departure at Llyr

= 10 34 - 08 40

= 1 hour 54 minutes

= 114 minutes

The time that Kathy would get back to the station is:

= Arrival time at Nuneaton + 1 hour 50 minutes

= 08 52 + 1 hour 50

= 10 42

This is too late for the 10 28 train to Milton Keynes.

The probability of randomly drawing and immediately eating three red M&Ms in a row from a bag that contains 7 red M&Ms out of 25 M&Ms total is 1/280.

This can be calculated by using the formula for probability, which is n/(N), where n is the number of desired outcomes and N is the total number of outcomes. In this case, n is equal to 7 (the number of red M&Ms) and N is equal to 25 (the total number of M&Ms). Therefore, the probability is 7/25, which simplifies to 1/280.In this case, the probability of drawing three red M&Ms in a row is 3 out of 25, or 3/25.

The sum of angles is 360 degrees is the required graph which represents the translation.

What is triangle ?

Triangle can be defined in which it consists of three sides , three angles and sum of three angles is always 180 degrees.

Given,

x , y and z are exterior angles of triangle ABC.

So,

By angle sum property of triangle

Angles of

1 + 2 + 3 = 180

1 + z = 180

3 + y = 180

2 + x = 180

z + 180 = 1

y + 180 = 3

x + 180 = 2

So,

by substituting we get ,

180 - z + 180 - y + 180 - x = 180

x + y + z = 180 +180 + 180 - 180

x+ y +z = 360

For the population model DP/dt = 0.3(1-P/200)(P/50-1)P describes how the population changes over time based on the value of P.

a) The population is in equilibrium at P = 0 and P = 200,

b) increasing for values of P between 50 and 200, and

c) decreasing for values of P between 0 and 50 and values of P greater than 200.

The population model

=> DP/dt = 0.3(1-P/200)(P/50-1)P

is a mathematical expression that describes the change in population size over time.

In this model, P(t) represents the population at time t and the rate of change of the population, DP/dt, is a function of P.

The population is in equilibrium when the rate of change is zero, meaning the population is neither growing nor declining. To find the equilibrium population, we set DP/dt = 0 and solve for P. In this case, we have:

=> 0.3(1-P/200)(P/50-1)P = 0

Solving for P, we find two solutions: P = 0 and P = 200. These represent the minimum and maximum populations, respectively.

The population is increasing when the rate of change is positive, meaning the population is growing.

If DP/dt > 0, then the population is increasing, and if DP/dt < 0, then the population is decreasing.

In this case, we have:

=> DP/dt = 0.3(1-P/200)(P/50-1)P

To simplify, we can write:

=> DP/dt = 0.3(P/50-1)(P/200-1)P

=> (P/50-1)(P/200-1) > 0.

This occurs when 50 < P < 200.

Therefore, the population is increasing for values of P between 50 and 200.

The population is decreasing when the rate of change is negative, meaning the population is declining.

If DP/dt > 0, then the population is increasing, and if DP/dt < 0, then the population is decreasing.

In this case, we have:

DP/dt = 0.3(1-P/200)(P/50-1)P

To simplify, we can write:

DP/dt = 0.3(P/50-1)(P/200-1)P

Since the sign of P is positive, the sign of DP/dt is negative for all values of P where

=> (P/50-1)(P/200-1) < 0.

Therefore, the population is decreasing for values of P between 0 and 50 and values of P greater than 200.

The constant y(t) = (y0-5)e^(-t) + 6e^(-4t) - 4t - 1; g(t) = (y0-4)e^(-t) + 6e^(-4t) - 4t; y0 = g(t).

What is algebra ?

Algebra is a branch of mathematics in which arithmetic operations and other formal manipulations are applied to abstract symbols rather than specific numbers.

Since y(t) = 6e^(-4t) - 4t - 1 is the general solution of the non-homogeneous equation y' + y = g(t), we can write it as:

y(t) = C1e^(-t) + 6e^(-4t) - 4t - 1

Setting t = 0 and using the initial condition y(0) = y0, we get:

y0 = C1 + 6 - 4 * 0 - 1

Solving for C1, we get:

C1 = y0 - 5

So, the general solution of the non-homogeneous equation is:

y(t) = (y0 - 5)e^(-t) + 6e^(-4t) - 4t - 1

Finally, the function g(t) can be found by comparing the general solution of the non-homogeneous equation with the right-hand side of the equation:

g(t) = (y0 - 5)e^(-t) + 6e^(-4t) - 4t - 1 + y = (y0 - 5 + 1)e^(-t) + 6e^(-4t) - 4t

Therefore, g(t) = (y0 - 4)e^(-t) + 6e^(-4t) - 4t.

So, the constant y(t) = (y0-5)e^(-t) + 6e^(-4t) - 4t - 1; g(t) = (y0-4)e^(-t) + 6e^(-4t) - 4t; y0 = g(t).

The angle that has the measure of 127 degree is angle MPK, and option 2 is the correct answer.

The opposing angles created by the junction of two lines are known as vertical angles or vertically opposite angles. A pair of angles that are vertically opposed to one another are always equal. Additionally, a vertical angle and the angle to which it is adjacent are supplementary angles, meaning their sum is 180 degrees.

From the given figure we see that the angle LPJ = 127 degree.

Also, angle LPJ and angle MPK are vertically opposite angles. So, they are equal in measure.

Let's call the number of women who liked watching comedies C, the number who liked watching fantasy movies F, and the number who liked watching romantic movies R.

From the information given, we know:

C = 1000 * 52% = 520 women liked watching comedies

F = 1000 * 45% = 450 women liked watching fantasy movies

R = 1000 * 60% = 600 women liked watching romantic movies

We also know that:

25% of women liked watching both comedies and fantasy, so 0.25 * 1000 = 250 women.

28% of women liked watching both romantic and fantasy, so 0.28 * 1000 = 280 women.

30% of women liked watching both comedies and romantic, so 0.30 * 1000 = 300 women.

However, these numbers overlap because some women like all three genres, so we have to subtract the number of women who like all three genres from our total. We don't know the number of women who like all three genres, but we can calculate it by adding up the number of women who liked two genres and subtracting from the total number of women:

Number of women who liked all three genres = (C + F + R - (C & F) - (C & R) - (F & R) + (C & F & R)) = (520 + 450 + 600 - 250 - 300 - 280 + (C & F & R))

Since 6% of women liked watching none of these movie genres, we can subtract this from our total:

C & F & R = 1000 - 6% * 1000 = 940 women

So the number of women who like watching at least two of the given genres = (520 + 450 + 600 - 250 - 300 - 280 + 940) = 1640 women.

To calculate the number of ways to arrange the books on a shelf, we can use the formula for permutations.

The formula for permutations is  [tex]\frac{n!}{(n-r)!}[/tex]  

where:  n is the total number of items

              r is the number of items being selected.

a. In this case, there are 8 books total (3 blue + 3 green + 2 red), and we are arranging all of them.

so n= 8 and r = 8, the number of arrangements is

[tex]\frac{8!}{(8-8)!}[/tex] = 8! = 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1 =  40320

So the answer to (a) is 40320.

b. To calculate the number of arrangements if the books of the same color are grouped, we can consider each group as one item.

There are 3 groups (blue, green, red), and we are arranging those

so n = 8 and r = 3.

Hence, the number of arrangements is

[tex]\frac{8!}{(8-3)!}[/tex] = [tex]\frac{8!}{5!}[/tex] = [tex]\frac{8x7x6x5x4x3x2x1}{5x4x3x2x1}[/tex] = 336

So the answer to (b) is 336.
