The probability that a pupil uses neither pool nor gym is 11/70

Probability is the likelihood that an event will happen. This can range from an event being impossible to some likelihood to being absolutely certain. In math terms, probability is on a scale from 0 to 1. Zero means the event is impossible, like rolling a seven on a die that only has digits from 1 to 6.

Number of pupil that can use pool and gym = 28

Number of people that can use pool = 48

Number of people that can use gym = 39

Number of people that can use pool only = 48 - 28 which is 20

Number of people that can use gym only = 39 - 28 = 11

Total number of persons that can use either pool, gym or both = 20 + 11 + 28 which is 59

Number of people that cannot use either or both of the facilities = 70 - 59 which is 11.

Probability = required outcome / possible outcome

Required outcome = 11

possible outcome = 70

Probability = 11/70

In conclusion, the probability that a pupil uses neither swimming pool nor gym is 11/70

4.2 team members per day

Step-by-step explanation:

5 + 4 + 2 + 7 + 3 = 21

21/5 = 4.2

An average is the arithmetic mean of a set of observations. The average number of team members who reached their goal per day is 4.2.

An average is the arithmetic mean of a set of observations. it is given by the formula,

\(\rm Average=\dfrac{\text{Sum of All the workers of reached their goal}}{\text{Number of working days}}\)

As it is given that the Number of team members that reach their goal on the weekdays Monday, Tuesday, Wednesday, Thursday, and Friday are 5, 4, 2, 7, and 3 respectively. Therefore, the average number of team members who reached their goal per day can be written as,

\(\rm Average=\dfrac{\text{Sum of All the workers of reached their goal}}{\text{Number of working days}}\\\\\\Average = \dfrac{5+4+2+7+3}{5} = \dfrac{21}{5}=4.2\)

Thus, the average number of team members who reached their goal per day is 4.2.

Step-by-step explanation:

The tangent of an angle is defined as the side opposite to that angle divided by the side adjacent to that angle. The tangent of angle A would be equal to the value of side BC divided by side AB. The value of side BC is 5, and the value of side AB is 12. The answer is 5/12.

Answer: ∠A=\(\frac{5}{12}\)

Step-by-step explanation:

Tangent is opposite over adjacent.

x = 26.75 min

26 minutes, would = 3.51. if you add .12 to that it is 3.63.

The fluid force on the sheet metal's top side when submerged horizontally in 7 feet of water is 12441.6 lb.

Given,

The area of the top side of a piece of sheet metal = 4 square feet

The sheet metal is submerged horizontally in 7 feet of water.

Fluid Force on the top side can be found as follows,

Formula used:

Fluid Force = weight-density × volume × depth of fluid

Fluid Force = 62.4 × volume × 7

As the sheet metal is completely submerged, the volume is equal to the area of the sheet metal.

Volume = Area × Depth

= 4 × 7

= 28

Fluid Force = 62.4 × 28 × 7

                   = 12441.6 lb

Thus, the fluid force on the sheet metal's top side when submerged horizontally in 7 feet of water is 12441.6 lb.

Therefore, the fluid force on the top side is 55838.08 lb.

Given, the area of the top side of a piece of sheet metal is 4 square feet and it is submerged horizontally in 7 feet of water.

The weight-density of water is 62.4 pounds per cubic foot.To find: the fluid force on the top side.Solution:Fluid force formula is given by,

F = ρ * g * V

Where, ρ is the density of the fluidg is the acceleration due to gravityV is the volume of the fluid displaced.Furthermore, the volume of fluid displaced is equal to the volume of the metal sheet submerged in the water.

Therefore,Volume of fluid displaced = Volume of metal sheet submerged in the water = area of metal sheet * depth submerged

Volume of metal sheet submerged in the water = 4 square feet * 7 feet

= 28 cubic feet

Now, calculate the fluid force on the top side of the metal sheet by using the fluid force formula.

F = ρ * g * V

Here, the density of water,

ρ = 62.4 pounds per cubic foot

g = 32.2 ft/s² (the acceleration due to gravity)

V = 28 cubic feet∴

F = 62.4 * 32.2 * 28 lb

= 55838.08 lb

Therefore, the fluid force on the top side is 55838.08 lb.

Step-by-step explanation:

We can easily see that h(x) is linear. That means it has a constant rate of change(i.e. the answer to the question is the same no matter the interval. It could be from 2 to 3, or 4 to 5, or -10000 to -9999, but the answer is the same).

Because the answer is the same across any interval, we can take the arbitrary interval 0 to 1 because it's easy to work with.

h(0)=-0.05(0)=0

h(1)=-0.05(1)=-0.05

As we can see, from 0 to 1, and thus for any unit interval, h(x) changes downard 0.05 units.

There is a maximum value of 7/6 located at (x, y) = (5/6, 7).

The function given to us is f(x, y) = xy.

The constraint given to us is 6x + y = 10.

Rearranging the constraint, we get:

6x + y = 10,

or, y = 10 - 6x.

Substituting this in the function, we get:

f(x, y) = xy,

or, f(x) = x(10 - 6x) = 10x - 6x².

To find the extremum, we differentiate this, with respect to x, and equate that to 0.

f'(x) = 10 - 12x ... (i)

Equating to 0, we get:

10 - 12x = 0,

or, 12x = 10,

or, x = 5/6.

Differentiating (i), with respect to x again, we get:

f''(x) = -12, which is less than 0, showing f(x) is maximum at x = 5/6.

The value of y, when x = 5/6 is,

y = 12 - 6x,

or, y = 12 - 6*(5/6) = 7.

The value of f(x, y) when (x, y) = (5/6, 7) is,

f(x, y) = xy,

or, f(x, y) = (5/6)*7 = 7/6.

Thus, there is a maximum value of 7/6 located at (x, y) = (5/6, 7).

Answer:

We can use the formula for the area of a kite, which is (1/2) x (diagonal1) x (diagonal2), to solve this problem.

Let's assume that the two diagonals of the kite have lengths d1 and d2, with d1 being the longer diagonal. We know that the area of the kite is 28 m^2, so we have:

(1/2) x d1 x d2 = 28

We also know that the height of the kite is 4 m, and the length of the other diagonal is 10 m. The height of the kite partitions the longer diagonal into two segments, each with length x. By the Pythagorean theorem, we have:

x^2 + 4^2 = (d2/2)^2

Simplifying, we get:

x^2 + 16 = (d2^2)/4

Multiplying both sides by 4, we get:

4x^2 + 64 = d2^2

Substituting d2 = 10, we have:

4x^2 + 64 = 100

Solving for x, we get:

4x^2 = 36

x^2 = 9

x = 3

Therefore, the value of x (the length of one of the two segments of the longer diagonal that are partitioned by the height) is 3 meters.

The ∆ABC is an isosceles triangle and have the base angles m∠A and m∠C equal to 51° and the angle m∠B is equal to 78°.

An isosceles triangle have the measure of its base angles to be equal, and the sum of the interior angles sum up to 180°.

Given that sides AB ≅ BC, then the triangle ∆ABC has two sides with similar length and base angles so;

angles m∠A and m∠C are the base angles are both equal to 51°

m∠B = 180° - (51 + 51)° {sum of interior angles of a triangle}

m∠B = 180° - 102°

m∠B = 78°

The 15th term of the geometric progression is a₁₅ = 25/2048

A geometric progression is a sequence in which each term is derived by multiplying or dividing the preceding term by a fixed number called the common ratio.

The nth term of a GP is aₙ = arⁿ⁻¹

The general form of a GP is a, ar, ar2, ar3 and so on

Sum of first n terms of a GP is Sₙ = a(rⁿ-1) / ( r - 1 )

Given data ,

Let the 15th term of the geometric progression be a₁₅

Now , the 4th term of the GP is a₄ = -25

The 9th term of the GP is a₉ = 25/32

Now , nth term of a GP is aₙ = arⁿ⁻¹

Substituting the values in the equation , we get

a₄ = ar³ = -25   be equation (1)

a₉ = ar⁸ = 25/32   be equation (2)

Divide equation (2) by equation (1) , we get

r⁵ = -( 1/32 )

r⁵ = - ( 1/2 )⁵

So , the common ratio r = -1/2

Now , the first term of the GP a is calculated by

ar³ = -25

when r = -1/2

a ( -1/2 )³ = -25

a/8 = 25

a = 200

Now , the 15th term of the geometric progression a₁₅ = ar¹⁴

Substituting the values in the equation , we get

a₁₅ = 200 ( -1/2 )¹⁴

a₁₅ = 200/16,384

a₁₅ = 25/2048

Hence , the 15th term of the GP is 25/2048
