It’s the End of the World As We Know It. The potential for an apocalypse worries me. What worries me most is that it could include any number of disasters. There is a 10% chance of a zombie infection. There is a 12% chance of Ragnorak (that’s the Norse apocalypse). There is an 8% chance of a UFO invasion6 . Heck, it could be like some show on the SyFy channel and all 3 might happen at the same time. (Translation: All three events are independent and not mutually exclusive.) (a) What is the probability that we will have an apocalypse of one sort or another? (b) I’m also a part-time actuary and in my need to prepare, I’ve decided to only prepare for those events which have a 0.9% chance or greater of occurring. Which types of apocalypses and combinations of apocalypses do I need to prepare for?

The city council is planning a new city park on a triangular plot of landformed by three intersecting streets.The designer placed the triangle on a grid to determine the side lengths andangle measures needed for the purchase and placement of a fencesurrounding the park. Each unit on the grid is one inch, which represents20 feet of actual length.The measure of angle CAB in the designer’s diagram is (5x + 1)°, and themeasure of angle ACB is (3x + 12.5)°.Create a report that provides a detaileddescription of the park. Include the following in your report:• the actual side lengths of the triangular plot of land• the type of triangle formed by the intersection of the three streets• the amount of fencing needed to surround the city park• the actual measure of each angle of the triangle

A researcher plants 22 seedlings. After one month, independent of the other seedlings, each seedling has a probability of 0.08 of being dead, a probability of 0.19 of exhibiting slow growth, a probability of 0.42 of exhibiting medium growth, and a probability of 0.31 of exhibiting strong growth. What is the expected number of seedlings in each of these four categories after one month? Calculate the probability that after one month:(a) Exactly three seedlings are dead, exactly four exhibitslow growth, and exactly six exhibit medium growth.(b) Exactly five seedlings are dead, exactly five exhibitslow growth, and exactly seven exhibit strong growth.(c) No more than two seedlings have died.

Determine whether the given procedure results in a binomial distribution (or a distribution that can be treated as binomial). If the procedure is not binomial, identify at least one requirement that is not satisfied. The YSORT method of gender selection, developed by the Genetics & IVF Institute, was designed to increase the likelihood that a baby will be a boy. When 70 couples use the YSORT method and give birth to 70 babies, the genders of the babies are recorded.

Birth weights of babies born to full-term pregnancies follow roughly a Normal distribution. At Meadowbrook Hospital, the mean weight of babies born to full-term pregnancies is 7 lbs with a standard deviation of 14 oz (1 lb = 16 oz). Dr. Watts (who works at Meadowbrook Hospital) has one delivery (for a full-term pregnancy) coming up tonight. What is the probability that the baby will weigh more than 7.5 lbs?

Suppose that Jean studied for the Graduate Management Admission Test (GMAT) using a well-known preparation class and was thrilled to receive a total score of 740. Her friend Eric, however, thinks she would have scored just as well without the class. To test the efficacy of the class, they obtain a small but random sample of 17 test results from other students using the same class. This sample's average is 559.42 with a standard deviation of 108.03. In comparison, the national average was 550.12. Assume the population's results are normally distributed but that its standard deviation is not known. Jean and Eric decide to perform a two-tailed t‑test at a significance level of α = 0.05. How many degrees of freedom should they use in their calculations? df = ___.

Suppose that the distribution of heart rates for medium sized dogs is normally distributed with mean 115 beats per minute and standard deviation 18 beats per minute. Stacy takes her medium sized dog, Scooter to the veterinarian for a wellness check and learns that scooters heart rate is 126 beats per minute. Answer question Ca. What is the standard score for scooters heart rate?= .61b.What percentage of medium-sized dogs have a heart rate that is lower than Scooters? = 76%c. Stacy learns from the veterinarian that dogs with heart rates in the upper 8% may be in danger of heart failure. For medium-sized dogs, a dangerous heart rate would be one above what value?

100 points and brainliestMira and Sasha observed two points, P and Q, on a number line.A number line is shown from negative 2 to positive 2 with increments of 2 over 8. A point P is shown at the seventh tick mark to the left of 0, and a point Q is shown at the seventh tick mark to the right of 0.Sasha said that the absolute values of the numbers represented by the two points are different.Mira said that the absolute values of the numbers represented by the two points are the same.Which of the following explains who is correct? A Sasha, because the points are of different signsB Sasha, because the points are at different locationsC Mira, because each of the two points is 14 over 8 units from 0D Mira, because the distance between the two points is 14 over 8 units
