Mathematics

shutvik [7]4 years ago

Step-by-step explanation:

Use binomial probability:

P = nCr p^r q^(n-r)

where n is the number of trials,

r is the number of successes,

p is the probability of success,

and q is the probability of failure (1-p).

Given n = 25, r = 5, p = 0.5, and q = 0.5:

P = ₂₅C₅ (0.5)⁵ (0.5)²⁵⁻⁵

P = 0.00158

The volume of a cylinder can is 1.54 litre and area of base is 77cm^2 Find its height​
goblinko [34]

Answer:

The height is 20 cm.

Step-by-step explanation:

First, we have to know that the volume formula is V = πr²h and the base area of cylinder is a circle. So we can let πr² be 77 cm² . Then we have to substitute the following values into the formula :

v = 1.54 \: l

v = 1540 \:  {cm}^{3}

v = \pi \times  {r}^{2}  \times h

Let πr² be 77,

Let v be 1540,

1540 = 77 \times h

77h = 1540

h = 1540  \div 77

h = 20 \: cm
