Answer:

1/8910720

Step-by-step explanation:

Number of ways they can be chosen :

⇒ 17 × 16 × 15 × 14 × 13 × 12

⇒ 272 × 15 × 14 × 13 × 12

⇒ 4080 × 14 × 13 × 12

⇒ 57120 × 13 × 12

⇒ 742560 × 12

⇒ 8910720

Hence, the probability will be :

⇒ P = 1 / number of ways

⇒ P = 1/8910720

Answer:

(A - B) - C = { 1 , 4 , 6 , 7 }

Step-by-step explanation:

A = { 1 , 2 , 3 , 4 , 5 }

B = { 4 , 5 , 6 , 7 }

A - B = { 1 , 2, 3 ,6 , 7 }

C = { 2 , 3 , 4 }

(A - B) - C = { 1 , 4 , 6 , 7 }

Tasia puts is x = 2. Using the equations given, Tasia will get:

Top Machine Output = 34

Bottom Machine Output = 34

The solution of an equation can be found by isolating the variable that is given in the equation to one side, while its value will be the quantity on the other side.

To find out what Tasia put in, we have to find the value of x that will make both equations equal.

Simplify the equations:

x + 40 + x - 10

= 2x + 30

2(x + 15)

= 2x + 30

This means both equations are the same and would give the same output if the same input value is put into them.

If the input Tasia puts is x = 2, we would have:

Top Machine Output = x + 40 + x - 10 = 2 + 40 + 2 - 10 = 34

Bottom Machine Output = 2(2) + 30 = 34

Step-by-step explanation:

Answer:

a) The mean income to 2 DP is £28142.86

b) The mean income excluding Deva's income is £19666.67

Step-by-step explanation:

The formula for mean is,

m = sum of terms/number of terms

Now n = number of terms = number of people = 7

And in the sum, we will input their salaries, so we get,

a) m = (13500 + 27500 + 13750 + 79000 + 19250 + 29000 + 15000)/7

m = 197000/7

m = 28142.85714

to 2 DP, we get,

m = £28142.86

b) Excluding Deva's income, i.e. excluding 79000, and then, the number of people becomes 6, so we get the mean,

Mean without Deva's Income = (13500 + 27500 + 13750 + 19250 + 29000 + 15000)/6

Mean without Deva's Income = 118000/6

Mean without Deva's Income = 19666.66667

to 2 DP, we get,

Mean without Deva's Income = 19666.67

or,

Mean without Deva's Income = £19666.67

By using the binomial theorem we establish the identity

\((2cos\alpha - 6sin\alpha ) ^ 2 + (6cos\alpha + 2sin\alpha ) ^ 2 = 40\)

There are numerous trigonometric identities relating to the side length and angle of a triangle. Only the right-angle triangle has trigonometric identities.

The six trigonometric ratios serve as the foundation for all trigonometric identities. Sine, cosine, tangent, cosecant, secant, and cotangent are the functions. All of these trigonometric ratios are defined using the sides of a right triangle, specifically the adjacent, opposite, and hypotenuse sides.

To establish the identity we need to expand the LHS by using the binomial theorem

\((2cos\alpha - 6sin\alpha ) ^ 2 + (6cos\alpha + 2sin\alpha ) ^ 2\\\\Here we can use the formulae (a-b)^{2} = a^{2} -2ab + b^{2} \\\(a + b)^{2} = a^{2} + 2ab + b^{2} \\ = (4cos^2 \alpha - 24cos\alpha * sin \alpha + 36sin^2 \alpha ) + (36cos^2 \alpha + 8sin\alpha * cos \alpha + 4sin^2 \alpha )\\= 40cos^2 \alpha + 40sin^2 \alpha \\= 40 (cos^{2} \alpha + sin^{2} \alpha )\\\\ cos^{2} \alpha + sin^{2}\alpha = 1\\= 40(1)\\=40 = RHS\\\)

Step-by-step explanation:

Basically the line in the centers of each are obviously not lined up, so they cant be the same, A is out, it looks to be about 6 points lower.

The correct answer is 3/2. In this case, x = 3/2, and its square, (3/2)^2 = 9/4, is rational. x satisfies the given condition.option (c)

To explain further, we need to understand the properties of rational and irrational numbers.

A rational number can be expressed as a fraction of two integers, while an irrational number cannot be expressed as a fraction and has non-repeating, non-terminating decimal representations.

In the given options, (a) √5102.0 (£) and (b) √2 are both irrational numbers.

Their squares, (√5102.0)^2 and (√2)^2, would also be irrational, violating the given condition. On the other hand, (d) 4/5 is rational, and its square, (4/5)^2 = 16/25, is also rational.

Option (c) 3/2 is rational since it can be expressed as a fraction. Its square, (3/2)^2 = 9/4, is rational as well.

Therefore, (c) 3/2 is the only option where x is rational, but its square is irrational, satisfying the condition mentioned in the question.

In summary, the number x that satisfies the given condition, where x^2 is irrational but x is rational, is (c) 3/2.option (c)

Using a calculator, the trigonometric ratio of sin 98 is approximately 0.9848.

One of the trigonometric ratio we have in mathematics is the sine ratio. We can use calculator to find the sine of an angle without making use of tables. To do this on your calculator, enter the sine function followed by the degree of the angle you want to find its sine. You will get your answer.

Using a calculator, we can find the sine of 98 degrees as follows:

sin 98° ≈ 0.9848

Rounding this to four decimal places, we get:

sin 98° ≈ 0.9848

Answer:

one tin of cheese $23

one tin of caramel $27

Step-by-step explanation:

let 'x' = cost of cheese tin

let 'y' = cost of caramel tin

10x + 8y = 446

22x + 11y = 803

i multiplied the first equation by -11 and the second by 8 to eliminate the 'y' terms

  -110x - 88y = -4906

+  176x + 88y = 6424

    66x = 1518

     x = 1518 / 66

     x = 23

find 'y':  10(23) + 8y = 446

             230 + 8y = 446

              8y = 216

               y = 27

The solution to the system of equations is x = -8/7, y = 4/7 and z = -2/7

The system of equations is given as

2x - y + 2z = -6

-3y + z = -2

2x - 3z = -4

Subtract 2x - 3z = -4 from 2x - y + 2z = -6

This is represented as

(2x - y + 2z = -6) - (2x - 3z = -4)

This gives

- y + 5z = -2

Multiply - y + 5z = -2 by 3

-3y + 15z = -6

Subtract -3y + 15z = -6 from -3y + z = -2

This is represented as

(-3y + z = -2) - (-3y + 15z = -6)

This gives

-14z = 4

Divide by -14

z = -2/7

Substitute z = -2/7 in - y + 5z = -2

- y - 5 * 2/7 = -2

This gives

- y - 10/7 = -2

Rewrite as:

y = 2 - 10/7

Evaluate

y = 4/7

Substitute z = -2/7 in 2x - 3z = -4

2x - 3 * 4/7 = -4

This gives

2x - 12/7 = -4

So, we have:

2x = 12/7 - 4

Evaluate

2x = -16/7

Divide by 2

x = -8/7

Hence, the solution to the system of equations is x = -8/7, y = 4/7 and z = -2/7

The amount of white paint used by Tamara to paint the bedroom walls is 2.125.

Fractions are numbers which are of the form a/b where a and b are real numbers. This implies that a parts of a number b.

Total amount of paint = 8.5

Three fourths of this amount is blue paint.

Amount of blue paint = (3/4) × 8.5 = 6.375

Rest is white paint.

Amount of white paint = Total paint - Amount of blue paint

                                     = 8.5 - 6.375

                                     = 2.125
