Answer:
Answer: 1 1/4
Step-by-step explanation:
1/4 * -5
The area of a circle is pi times r^2. Because you have a half circle, divide this number by two. They give you the diameter of the circle, 15 m, so divide this in half to get the radius. Therefore to find the area of the semi circle, you’ll multiply 1/2 by pi times 7.5^2. This will give you about 88.36 m^2. To find the area of the trapezoid, you use the formula A=(1/2)(h)(a+b) where h is the height and a and b are the lengths of the bases. Therefore A=(1/2)(12)(12+21). This will give you an area of 198 m^2. Now you can add the two together to get your total area, so 198 + 88.36 = 286.36 m^2.
Answer:
C Population
Step-by-step explanation:
Population
The above case is an example of population survey. Here a set of 56 surveys have been performed with set of 56 students. The survey is conducted on a large scale. In statistics a population is set of similar items or events which is of the interest for some event or experiment. Since, the above experiment fits the definition of the Population, it is example of population survey.
The answers to the question are
- The bank has to assume normal behavior of all of the defaults.
- Yes they do appear reasonable
- the assumption would be 12.5. The reserves would be enough
<h3>What is a binomial probability model?</h3>
This is the model in mathematics as well as statistics that allows us to carry out the computation of a probability. The way that this is done is through the observation of a given number of successes. This is after the process has being carried out in a repeated manner.
a. The bank would have to assume that the defaults would have a normal distribution in order to use a binomial model.
b. We can say that they are reasonable in the context from which they appear in the problem.
c. 5% of 250
= 12.5
Given that 25 reserves are there we can say that the reserves are going to be enough.
