The failure of a circuit board interrupts work that utilizes a computing system, until a new board is delivered. The delivery time, Y, is uniformly distributed on the interval two to six days. The cost of a board failure and interruption includes the fixed cost c0 of a new board and a cost that increases proportionally to Y2. If C is the cost incurred, C = c0 + c1Y2.
A) Find the probability that the delivery time exceeds two days.
B) In terms of c0 and c1, find the expected cost associated with a single failed circuit board.
Answers
Answer:
a) 1 ( 100% )
b) Co + 46/3 C1
Step-by-step explanation:
Delivery time = Y
Interval = 2 to 6 days
cost incurred ( C ) = Co + C1 Y^2
a) determine the probability that the delivery time exceeds two days
since the delivery time is uniformly distributed on the interval 2 to 6 days the probability of having a delivery time > 2 days will be = 1
b) Determine the expected cost associated with a single failed circuit board
E ( Y^2 ) = 46/3
hence the cost associated with a single failed circuit board =
E ( C ) = Co + 46/3 C1

Passes the true premises test and fails the proper form test. Fails the true premises test and passes the proper form test. Fails the true premises test and fails the proper form test. None of the above.
Answers
Answer:
Fails the true premises test and fails the proper form test
Explanation:
A valid argument must pass the true premises test and the proper form test.
True premises test checks to see if what the premises is saying is true about the world, example- pigs do not have wings and so the argument fails the true premises test. Proper form test assumes the premises is true and then checks to see if a valid conclusion was drawn based on the premises(even though it might fail the true premises test and may not be true about the world)
A researcher wants to determine if college students typically drink more than 3 times per week. She collects data on 125 college students. From the sample, she finds that they drank an average of 3.5 times per week, with a standard deviation of 2.3 drinks. Use a 5% significance level for any testing. Based on the scenario above, which of the following is TRUE regarding the type of test that would need to be performed?
a. It is a two-tailed test.
b. It must be completed using the critical value approach.
c. It is a one-tailed test.
d. We reject the null and prove our claim.
e. We would need to estimate the significance level from the data.
f. Hypothesis testing cannot be performed on percentages.
Answers
Answer:
C: It is a one-tailed test.
Step-by-step explanation:
We are told the researcher wants to determine if college students typically drink more than 3 times per week.
This means the null hypothesis is;
H0: μ ≥ 3
this indicates that it's a one tailed test as the null hypothesis is only to the right side of 3 and thus just one tail.
This question will be solved using p-value approach since we are given population mean, sample mean, sample size and standard deviation.
We can't reject the null without finding out the p-value and seeing if it is less than the significance value given.
Hypothesis testing can be done done proportions or percentages.
Thus, the correct option is one-tailed test.

it is 1 minus 1 over 6 since you aren’t finding the price after reduction. Your finding the original one which means you need to minus by one (6 over 6= 1) so u would do 1 - 1/6

The median is 6
Step-by-step explanation:
First put the numbers in order: 3,4,4,4,5,7,7,8,9,12
Here, the 5th & 6th terms are 5 &7
So, median = 5+7/2
=12/2
=6
Answer:
6
Step-by-step explanation:
For funding out the median firstly we need to arrange the data in ascending or descending order . Here on arranging the given data in ascending order we have ,
3,4,4,4,5,7,7,8,9,12The median is the middle most observation , in case of odd nos . And the mean of two middlemost observations in case of even nos . Here the number of data is even , and the two middlemost observations are 5 and 7 , so ,
=> Median = x₁ + x₂ / 2
=> Median = 5 + 7/2
=> Median = 12/2
=> Median = 6
Hence the median of the given data is 6 .Are the two triangles above similar? Why or why not?

C. No, there is not enough information given to prove similarity.
D. No, right triangles are never similar.
Answers
Hope this helps :))
No, Triangles with one congruent angle are never similar so the correct option is D.
What is similar triangle?Similar triangles are triangles that have constant form, however their sizes might vary. All equal triangles, squares of any aspect lengths are samples of similar objects. In other words, if 2 triangles are similar, then their corresponding angles are congruent and corresponding sides are in equal proportion.
For AAA similarity postulate; Two triangles are similar if two corresponding angles of them are of same measure. It is because when two pairs of angles are similar, then as the third angle is fixed if two angles are fixed, thus, third angle pair also gets proved to be of same measure.
If the triangles, have only 1 congruent angles , it can not be said similar because for a triangle to be similar , minimum two criteria must be equal .
Hence we can conclude that triangles with one congruent angle are never similar.
