Answer:
(a) cos(55°) = 11/x
Step-by-step explanation:
The marked sides are the hypotenuse (x) and the side adjacent to the given angle (11). Then the relevant trig ratio is ...
Cos = Adjacent/Hypotenuse
cos(55°) = 11/x
Answer:
a) 
b) 
Step-by-step explanation:
In both parts of the problem y varies directly as x. So, they have the following form:

Where k is the constant of proportionality.
Therefore, you must find k and then write the equations.
a) Solve for k:

Then, the equation is:

b) Solve for k:

Then, the equation is:

b) The probability for the couple to be very confident that they will get at least one boy in 6 children is
%
Step-by-step explanation:
The probability of having a boy or girl is 
A couple plans to have 6 children
Probability of having at least one male child

On solving the above term, we get -

The probability for the couple to be very confident that they will get at least one boy in 6 children is

Thus, the probability is very high
