Calculating Suppose that only 200 sperm out of
the original 400 million sperm deposited in the
vagina survive the journey to the egg. What
percentage is this?

Solution:

Given that,

Suppose that only 200 sperm out of  the original 400 million sperm deposited in the  vagina survive the journey to the egg

400 million = 400000000

The percentage is given as:

Therefore,

Thus, 0.00005 % sperms deposited in the  vagina survive the journey to the egg.

the nearest power is 1.651.

means 7482 to the 1.651th power is almost equal to 2489287

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
