Answer:
Option A. <A and <B are complementary angles
Option D. 
Step-by-step explanation:
we know that
If ABC is a right triangle
then
------> by complementary angles
and


Remember that

so


The features in a function can be used to describe real-world events. The features and their match are:
- <em>domain: all possible lengths of the tomato patch</em>
- <em>y - intercept: area of the bell pepper patch when the length of the tomato patch is 0
</em>
- <em>x - intercept: length of the tomato patch when the area of the bell pepper patch is 0</em>
- <em>range: all possible areas of the bell pepper patch</em>
<em />
For Melissa's garden, the input and output variables are:
- <em>Input: tomato patch</em>
- <em>Output: bell pepper patch</em>
The range is the list of possible output values, while the domain is the list of possible input values.
This means that: the range is all possible areas of the bell pepper patch while the domain is all possible lengths of the tomato patch
Also, the x and y intercepts are when the values of the output and input variables are 0, respectively.
Using the above comparison;
The y - intercept is the area of the bell pepper patch when the length of the tomato patch is 0, while the x - intercept is the length of the tomato patch when the area of the bell pepper patch is 0.

Answer:
The standard deviation for the number of defective parts in the sample is 1.88.
Step-by-step explanation:
The sample is with replacement, which means that the trials are independent, and thus, the binomial probability distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The standard deviation of the binomial distribution is:
68 defective out of 400:
This means that 
From the shipment you take a random sample of 25.
This means that 
Standard deviation for the number of defective parts in the sample:

The standard deviation for the number of defective parts in the sample is 1.88.
Answer:
The correct option is B.
Step-by-step explanation:
If polar coordinates of point P are

Where, r is real number and θ is in radian, then all polar coordinates of point P are defined as


The given coordinates are
. So, all polar coordinates of point P are


Therefore correct option is B.
Answer:
.B. the eight business students who participated
Step-by-step explanation:
The experimental units are entities (objects, animals, people) on which an experiment is performed. For example testing the efficiency of a particular treatment on four sick goats. in this case the four sick goats are the experimental units.
For the case above, the eight business students who participated in the experiment are the experimental units.
