Give formulae for half yearly calculation of compound intrest formula.

Mathematics

Cloud [144]3 years ago

The formula for compound interest, compounded once per year, is:

A = P(1+r)^t, where r is the annual interest rate as a decimal fraction and t is the number of years.

If interest is compounded twice per year, then the above formula is changed to:

A = P(1+r/2)^(2t), where the '2' indicates twice-per-year compounding.

If interest is compounded n times per year, then the above formula is changed to:

A = P(1+r/n)^(nt).

A number cube is rolled three times. What is the probability of rolling a number less than 3 each time?
sergeinik [125]

Answer:

1/27

Step-by-step explanation:

The outcomes when rolling a die are 1,2,3,4,5,6

getting less than 3 = 1,2

P( less than 3) = outcomes of less than 3 / total

                        = 2/6 = 1/3

Since the events are independent we can multiply the probabilities

P( less than 3, less than 3, less than 3) = 1/3 * 1/3*1/3 = 1/27

A vase in the shape of an oblique cylinder has the dimensions shown. What is the volume of the vase?
fenix001 [56]

The image is missing so i have attached it.

Answer:

Volume = 1.5 litres

Step-by-step explanation:

Using pythagoras theorem, we can get the height (h) of the cylinder

14² + h² = 17²

h² = 289 - 196

h = √93

Now, volume of a cylinder is;

V = πr²h

In the image, r = diameter/2 = 14/2 = 7cm

Thus,

V = π × 7² × √93

V = 1485 cm³

Now, 1 litre = 1000 cm³

Thus, volume = 1485/1000 = 1.485 litres ≈ 1.5 litres
