The fraction of those who were cast and got major roles is 1/5.

The number of the students who were cast out of the Ninety students auditioned  for the school play is calculated as follows;

Total number of students = 90

Number of students who were cast = ¹/₃ x 90 = 30

Number of students who go major role = 6

The fraction of those who were cast and got major roles is calculated as follows;

fraction of students who got major role = 6/30

fraction of students who got major role =  1/5

Two possible lengths for CD if C, D, and E are collinear, CE 17.9 cm, and DE = 8.2 cm is 12.3cm and 19.3cm.

In space, a point is a precise position or location. It is possible to depict it in relation to a coordinate system and its origin. It has no length and is a zero-dimensional entity.

A line is made up of an unlimited number of points that form a straight line. One-dimensional objects like lines lack both thickness and width. It stretches forever in both directions. An endpoint and a beginning point define a line segment, which is a component of a line. A linear equation can be used to depict a line.

The direction cosines and direction angles will be - [tex]\frac{x}{r},\frac{y}{r},\frac{z}{r}[/tex] and

cos⁻¹([tex]\frac{x}{r}[/tex]), cos⁻¹([tex]\frac{y}{r}[/tex]),cos⁻¹([tex]\frac{z}{r}[/tex]) respectively.

The direction cosines of a specified vector, m = xi + yj + zk, are the cosines of the angles it makes well with x, y, and z axes.

The direction cosines of m are cos a, cos b, and cos c  in the x, y, and z axes, respectively, if a forms the angles a,b and c (which are the direction angles) with the x, y, and z axes, respectively.

Let us consider equation as =  [tex]xi + yj +zk[/tex]

vector of the equation will be - (x,y,z)

r = length of vector = [tex]\sqrt{x^{2} +y^{2} +z^{2} }[/tex]

The direction cosines will be -

[tex]\frac{x}{r},\frac{y}{r},\frac{z}{r}[/tex]

angles will be - cos⁻¹([tex]\frac{x}{r}[/tex]), cos⁻¹([tex]\frac{y}{r}[/tex]),cos⁻¹([tex]\frac{z}{r}[/tex])

Let us consider an example,

If we have vector as (1,2,3)

= i + 2j + 3k

= r = [tex]\sqrt{1^{2} +2^{2} +3^{2} }[/tex]

= [tex]\sqrt{14}[/tex]

The equation for the parallel street that passes through (2, -3) is: B. y = 3x - 9.

Two lines that lie parallel to each other will have a slope (m) that is of the same value. The equation can be written as y = mx + b in slope-intercept form.

Find the slope of the line that passes through (4, 5) and (3, 2):

Slope (m) = change in y / change in x = (5 - 2)/(4 - 3)

Slope (m) = 3/1

Slope (m) = 3

The slope of a parallel line would also be 3.

Substitute (a, b) = (2, -3) and m = 3 into y - b = m(x - a):

y - (-3) = 3(x - 2)

y + 3 = 3x - 6

Subtract 3 to both sides of the equation

y + 3 - 3 = 3x - 6 - 3

y = 3x - 6 - 3

y = 3x - 9

Therefore, the equation for the parallel street that passes through (2, -3) is: B. y = 3x - 9.

A statement 'He is not the winner, then, he is sick.' is a valid argument.

To test the validity of a given argument, we need to see if we can find a counter-example that makes one of the statements non-valid. If after analyzing the statements we can't find a counter-argument, then we can conclude that the argument is valid.

Here we will find that the argument is valid.

We can write given statement as:

1) If he participates in a race then he is the winner.

2) Either he participates in the race, or he is sick.

3) He is not the winner, then, he is sick.

Now, from the first statement, we know that this person participates in a race, he wins.

From the second statement we know that he only participates if he is not sick, we can rewrite that one as:

"If he is sick, then he does not participate in the race".

Finally, from the third one, if he does not win, then he is sick.

This makes sense, he only does not participate when he is sick, then the only races where he is not the winner, are these races where he does not participate, and he does not participate only if he is sick, then this is a valid argument.

Concluding, the 3 statements are valid, as we can't find any counter-argument to any of these 3.

Therefore, a statement 'He is not the winner, then, he is sick.' is a valid argument.

Yes, Lila and Wassim saved the extra money of £16.

For the given data in question;

Charge/person for Camping Site : £5 per night

Charges for Camping Site Tent = £15 per night for Tent pitch > 10m²

calculate the tent pitch;

Tent Pitch = 2.5 × 4.2 = 10.5 > 10

Total charges for tent = £15 per night

As, 2 Lila and Wassim sharing Tent

Total charges per night = Charge/person + Charges for Camping Tent

= 2× £5 + £15

= £25 per night

For every 5 nights of the stay, pay is 4.

Cost for 10 nights for two persons.

Lila and Wassim have to pay the cost  for 8 Nights;

Total charges = £25 × 8  = £200

Lila and Wassim each plan to save £12 per week  for 9 weeks.

Thus, the total Saving = 2 ×  9 ×  12 = £216

total Saving =  216 > 200

As, total savings of Lila and Wassim are £216 which are greater than the £200 cost of camping.

The extra money saved is;

= £260 - £200

= £16.

Using the midpoint concept, the other endpoint of the segment is: G(18,-9).

The problem asks for the coordinates of the other endpoint, given by point G.

The midpoint between two points is the halfway point between them, and is found using the mean of the coordinates.

Hence the x-coordinate of G is found as follows:

8 = (x - 2)/2

x - 2 = 16

x = 18.

The y-coordinate of G is found as follows:

0 = (y + 9)/2

y + 9 = 0

y = -9.
