1. This is an obtuse angle. It is more than 90 degrees, but less than 180 degrees.

2. Perpendicular would mean right angle, which equals 90 degrees.

3. An obtuse angle is greater than 90 and less than 180, so the answer would be 100 degrees.

4. An acute angle is less than 90 degrees, so the answer would be 28 degrees.

Answer:

Choices C and D

Step-by-step explanation:

The most simplest way is just to solve each one and see which two have the same answer as the first expression.

But you could also see that both of the \frac{4}{7} are going to cancel each other out so you are left with -\frac{8}{9} +\frac{9}{8}  which is also choice C.

For choice D I distributed the negative one to the insides of the parenthesis that left me with -\frac{4}{7}-\frac{8}{9}+\frac{4}{7} +\frac{9}{8}  which is the same expression as the first one.

A particular employee arrives at work sometime between 8:00 a.m. and 8:30 a.m. Based on past experience the company has determin
Gala2k [10]

Answer:

0.3333 = 33.33% probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value between c and d is given by:

P(c \leq X \leq d) = \frac{d - c}{b - a}

A particular employee arrives at work sometime between 8:00 a.m. and 8:30 a.m.

We can consider 8 am = 0, and 8:30 am  = 30, so a = 0, b = 30

Find the probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.

Between 15 and 25, so:

P(15 \leq X \leq 25) = \frac{25 - 15}{30 - 0} = 0.3333

0.3333 = 33.33% probability that the employee will arrive between 8:15 a.m. and 8:25 a.m.
