PLZ HELP!Two submersibles, one red and one blue, started rising toward the surface at the same time. They each rose at a constant speed. the red submersible starts rising from an altitude of 80 meters below the surface. after 30 seconds, it was 60 meters below the surface. the following equation gives the altitude (in meters relative to the surface) of the blue submersible as a function of time (in seconds). A= -90 + 0.6tWhich submersible started rising from a higher altitude?Which submersible rose faster?

The inverse notation f -1 used in a pure mathematics problem is not always used when finding inverses of applied problems. Rather, the inverse of a function such as C = C(q) will be q = q(C). The following problem illustrates this idea. The ideal body weight w for men (in kilograms) as a function of height h (in inches) is given by the following function. W(h) = 49 + 2.2(h- 60) What is the ideal weight of a 6-foot male? The ideal weight, W, of a 6-foot male is kilograms. (Round to the nearest tenth as needed.) Express the height h as a function of weight W. Verify your answer by checking that W(h(W)) = W and h(W(h))h.

I made a distribution of 15 apartment rents in my neighborhood. One apartment had a higher rent than all the others, and this outlier caused the mean rent to be higher than the median rent. Does this make sense because the outlier with a large value increases the mean, but does not affect the median?

An article states that false-positives in polygraph tests (tests in which an individual fails even though he or she is telling the truth) are relatively common and occur about 10% of the time. Suppose that such a test is given to 10 trustworthy individuals. (Round all answers to four decimal places.) What is the probability that all 10 pass?

Emergency 911 calls to a small municipality in Idaho come in at the rate of one every two minutes. Assume that the number of 911 calls is a random variable that can be described by the Poisson distribution. (a) What is the expected number of 911 calls in one hour? per hour (b) What is the probability of three 911 calls in five minutes? If required, round your answer to four decimal places. (c) What is the probability of no 911 calls during a five-minute period? If required, round your answer to four decimal places.

According to a study conducted by an organization, the proportion of Americans who were afraid to fly in 2006 was 0.10. A random sample of 1,300 Americans results in 143 indicating that they are afraid to fly. Explain why this is not necessarily evidence that the proportion of Americans who are afraid to fly has increased. Select the correct choice below and. if necessary, fill in the answer box to complete your choice. This is not necessarily evidence that the proportion of Americans who are afraid to fly has increased above 0.10 because the probability of obtaining a value equal to or more extreme than the sample proportion is . which is not unusual.
