A scuba diver descends farther down into the ocean from an initial depth of 15.2 feet below sea level. The scuba diver descends

at a constant rate for 212 minutes and reaches a depth no more than 46.7 feet below sea level.
What is the maximum rate, r, that the scuba diver may descend?

Answer:

r <= 12.6

Step-by-step explanation:

Let's calculate the rate at which he descends:

r = (46.7 - 15.2)/212 = 0.15 feet/minute

7. The claim that started this investigation was that students majoring in engineering are more likely to be in the marching ban
Genrish500 [490]

Answer:

See explanation below.

P(M|E) > P(M|O)

Step-by-step explanation:

Notation

First we need to define the following events:

E = The student is in a major of enginnering

O= The student is in a major different from enfinnering

M= The student is in the marching band

Solution for the problem

For this case we can calculate the following probability:

P(M|E) =\frac{P(M and E)}{P(E)}

And that represent the following event: "Given a randomly selected student is an engineering major, what is the probability  the student is in the marching band"

And the probability that need to calculate to compare is this one:

P(M|O) =\frac{P(M and O)}{P(O)}

And that represent the following event: "Given a randomly selected student is NOT an engineering major, what is the probability  the student is in the marching band"

And if the claim is satisfied we need to see this:

P(M|E) > P(M|O)

there are 21 marbles in a blue jar. the blue jars has 3 times as many marbles as a red jar. let m be the number of marbles in th
jarptica [38.1K]

Answer:

m=7

Step-by-step explanation:

1 blue jar = 21 marbles

1 blue jar = 3 red jars

Therefor

21 marbles= 3 red jars

(Now let m=1 red jar)

21= 3m

(Then sine we have 3m dived both sides by 3 to isolate the m)

21/3= 3m/3

7=m
