Answers

Answer:

16 - 6n

Step-by-step explanation:

10 , 4 , -2 , - 8 .....

This is arithmetic sequence

first term = 10

Common difference = 2nd term - first term

                          d    = 4 - 10

                            d = -6

nth term = a₁ + (n -1)d

              = 10 + (n - 1)*(-6)

             = 10 + n*(-6) - 1*(-6)

             = 10 - 6n + 6

             = 10 + 6 - 6n

             = 16 - 6n

A broker charges customers a fixed fee of £150 plus 5.50% of the amount of all investments made. If a customer invests £40 000 through the broker, what is the total brokerage payable?
(10 Marks)

Answers

Answer:

Total payable brokerage = £2350

Step-by-step explanation:

Given that:

Fixed fee charged by broker = £150

Percent of fee charged = 5.50%

Amount invested by customer = £40,000

Fee charged = [tex]\frac{5.50}{100}*40000[/tex]

Fee charged = 5.50 * 400 = £2200

Total brokerage payable = £150 + £2200 = £2350

Hence,

Total payable brokerage = £2350

In Tokyo, construction workers earn an average of ×420,000 (yen) per month with a standard deviation of ×20,000, while in Hamburg, Germany, construction workers earn an average of €3,200 (euros) per month with a standard deviation of €57. A worker making ×460,000 per month in Tokyo is earning relatively the same as one earning €3,300 per month in Hamburg?

Answers

Answer:

Since they have different z-scores, they are not earning relatively the same.

Step-by-step explanation:

We use z-scores to solve this question.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this question:

They will be earning relatively the same if they have the same z-score.

Tokyo:

Earns 460, mean 420, standard deviation 20. So [tex]X = 460, \mu = 420, \sigma = 20[/tex]. The z-score is:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{460 - 420}{20}[/tex]

[tex]Z = 2[/tex]

Hamburg:

Earns 3300, mean 3200, standard deviation 57. So [tex]\mu = 3300, \sigma = 3200, \sigma = 57[/tex].

The z-score is:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{3300 - 3200}{57}[/tex]

[tex]Z = 1.75[/tex]

Since they have different z-scores, they are not earning relatively the same.

The magnitude and direction of two vectors are shown in the diagram. What is the magnitude of their sum? ​

Answers

Separate the vectors into their x- and y-components. Let u be the vector on the right and v the vector on the left, so that

u = 4 cos(45°) x + 4 sin(45°) y

v = 2 cos(135°) x + 2 sin(135°) y

where x and y denote the unit vectors in the x and y directions.

Then the sum is

u + v = (4 cos(45°) + 2 cos(135°)) x + (4 sin(45°) + 2 sin(135°)) y

and its magnitude is

||u + v|| = √((4 cos(45°) + 2 cos(135°))² + (4 sin(45°) + 2 sin(135°))²)

… = √(16 cos²(45°) + 16 cos(45°) cos(135°) + 4 cos²(135°) + 16 sin²(45°) + 16 sin(45°) sin(135°) + 4 sin²(135°))

… = √(16 (cos²(45°) + sin²(45°)) + 16 (cos(45°) cos(135°) + sin(45°) sin(135°)) + 4 (cos²(135°) + sin²(135°)))

… = √(16 + 16 cos(135° - 45°) + 4)

… = √(20 + 16 cos(90°))

… = √20 = 2√5

Example 24 In a school there are 20 teachers who teach mathematics or physil
these, 12 teach mathematics and 4 teach both physics and mathematics. How Ex
teach physics ?​

Answers

Answer:

The number of teachers who teach  physics   n(P) = 12

Step-by-step explanation:

Step(i):-

Given that the number of teachers who teach mathematics or physics

n(MUP) = 20

Given that  the number of teachers who teach mathematics

n(M) = 12

Given that the number of teachers who teach both mathematics and physics

n(M∩P) = 4

Step(ii):-

By using   n(A∪B) = n(A) + n(B) - n(A∩B)

                n(M∪P) = n(M) +n(P) - n(M∩P)

                20         = 12 + n(P) - 4

               20 -12 +4 = n(P)

                    n(P) = 12

Final answer:-

The number of teachers who teach  physics   n(P) = 12

The second is freedom of every person to worship God in his own wayeverywhere in the world. The third is freedom from wantwhich, translated into world terms, means economic understandings which will secure to every nation a healthy peacetime life for its inhabitantseverywhere in the world. The fourth is freedom from fearwhich, translated into world terms, means a world-wide reduction of armaments to such a point and in such a thorough fashion that no nation will be in a position to commit an act of physical aggression against any neighboranywhere in the world. That is no vision of a distant millennium. It is a definite basis for a kind of world attainable in our own time and generation. That kind of world is the very antithesis of the so-called new order of tyranny which the dictators seek to create with the crash of a bomb. To that new order we oppose the greater conceptionthe moral order. A good society is able to face schemes of world domination and foreign revolutions alike without fear. Since the beginning of our American history, we have been engaged in changein a perpetual peaceful revolutiona revolution which goes on steadily, quietly adjusting itself to changing conditionswithout the concentration camp or the quick-lime in the ditch. The world order which we seek is the cooperation of free countries, working together in a friendly, civilized society.

Freedom means the supremacy of human rights everywhere. Our support goes to those who struggle to gain those rights or keep them. Our strength is our unity of purpose.
