Rule to convert from DMS (degrees minutes seconds) format to pure degrees:

x deg, y min, z sec = x+y/60+z/3600

Use that rule to get...

88 deg, 22 min, 45 sec = (88+22/60+45/3600) degrees

88 deg , 22 min, 45 sec = 88.3791667 degrees (approx)

Now use the tangent function on your calculator

tan(88.3791667) = 35.34015179

Answer is choice C. It's not a perfect match due to some rounding errors, but it's close enough.

Answer:

$\boxed{\red{15 {x}^{2} + 11xy - 12 {y}^{2}}}$

Step-by-step explanation:

$\blue{(5x - 3y)(3x + 4y)} \\ \blue{5x(3x + 4y) - 3y(3x + 4y)} \\ \blue{15 {x}^{2} + 20xy - 9xy - 12 {y}^{2} } \\ \pink{= 15 {x}^{2} + 11xy - 12 {y}^{2} }$

Igoryamba

Answer:

A. Yes, the result is a binomial probability distribution.

Step-by-step explanation:

The experiment above depicts a binomial probability distribution because the 4 required conditions are met :

1.) The distribution is independent as the possible outcome of each trial is the same.

2.) There are two possible categories and the result of each trial is one of two outcomes : Yes or No

3.) The number of observation is fixed at sample size of 5500

4.) The probability of success and failure of each trial is the same for all trials in the sample.

Hence, we can conclude that the experiment depicts a binomial probability distribution.
