[tex] \huge \mathfrak{ Answer : - }[/tex]

60 students walk to school, which is 20 % of the total students studying there,

so, let the the total number of students be " x "

now, we know

=》

[tex]20 \% \: \: of \: \: x = 60[/tex]

=》

[tex] \dfrac{20}{100} \times x = 60[/tex]

=》

[tex] \dfrac{1}{5} \times x = 60[/tex]

=》

[tex]x = 60 \times 5[/tex]

=》

[tex]x = 300[/tex]

hence, the total number of students :

x = 300

Answer:

simple answer 300

Step-by-step explanation:

20%=60 students. 100%/20%=5. 60*5=300 students

Answer:

1/2

Step-by-step explanation:

Total -- 6 people

3 people -- 3/6 = 1/2

Therefore, the answer is 1/2

The probability that a randomly selected person will have red hair for this case is obtained  being 1/2 (in fraction form) or 0.5 (in decimal form).

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]

where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.

For this case, we're given that:

We can assume that all the people are equally likely to get selected for this case as selection was done randomly, so all of the 6 people was likely to get chosen without bias.

Now, let we take:

E = event of selecting a red hair person

Then, the number of ways a selection ends up making E happen = 3 (as there are 3 people with red hair, so any of those 3 getting selected will make E happen).

Total number of ways selection can be done = 6 (as selection is done from those 6 people).

Thus, we get:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)} = \dfrac{3}{6} = \dfrac{1}{2} = 0.5[/tex]

Thus, the probability that a randomly selected person will have red hair for this case is obtained  being 1/2 (in fraction form) or 0.5 (in decimal form).

For the given condition the age of the son will be 69 years.

A mathematical equation asserts the equality of two expressions, which may or may not contain variables or integers. Equations are fundamental concerns, and efforts to rationally address them have served as the primary driving forces behind the creation of mathematics.

Suppose the two-digit number is x,

The father's and son's ages are 10x+y and 10y+x respectively.According to the given condition,

(10x+y) -(10y+x)=27

9x-9y=27

x-y=27/9

x-y=3

The value of x and y will be 4 and 1.

At x=9 and y=6, the age of the son is obtained as,

=10×6+9

=69 years

Thus, the age of the son will be 69 years.

The surface area of the given composite figure will be 384 square cm.

The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.

In the given image we have a composite figure one is a rectangular cuboid and the other is a triangular prism. The surface area will be equal to the sum of all the outer sides of the figure.

The surface area of the triangular shape will be calculated as:-

SA = 2( Area of triangle ) + Area of rectangular surfaces

SA = 2 ( (1/2) B x H )  + (5 x 6 ) + ( 6 x 3  )

SA = ( 3 x 4 ) + (  30 ) + ( 18 )

SA = 12 + 30 + 18

SA = 60 square cm

The surface area of the rectangular cuboid will be calculated as:-

SA = ( 4 x 6 ) + 2 ( 158 x 4 ) + 2 ( 15 X 6 )

SA = 24 + 120 + 180

SA  = 324 square cm

Total surface area will be = 324 + 60 = 384 square cm.

Therefore the surface area of the given composite figure will be 384 square cm.
