While conducting experiments, a marine biologist selects water depths from a uniformly distributed collection that vary between
seraphim [82]

Answer:

55% probability that a randomly selected depth is between 2.25 m and 5.00 m

Step-by-step explanation:

An uniform probability is a case of probability in which each outcome is equally as likely.

For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.

The probability that we find a value X between c and d is given by the following formula.

P(c \leq X \leq d) = \frac{d - c}{b - a}

While conducting experiments, a marine biologist selects water depths from a uniformly distributed collection that vary between 2.00 m and 7.00 m.

This means that a = 2, b = 7

What is the probability that a randomly selected depth is between 2.25 m and 5.00 m?

P(2.25 \leq X \leq 5) = \frac{5 - 2.25}{7 - 2} = 0.55

55% probability that a randomly selected depth is between 2.25 m and 5.00 m

What are the roots of x in -10x^2+12x-9=0

They do not exist.  The parabola never crosses the x-axis (which is the same thing as the roots).

Factorise this expression:
Vesnalui [34]
Yes you are correct, GCF of both terms is x, so you can factor x out.

3x - x²   ⇒   x(3 - x)

How did they get that answer? please answer
OverLord2011 [107]

Answer:

Look at my explanation

Step-by-step explanation:

The circumference of a circle is 2πr, so you can set it up like this since the circumference was 22π.

2πr = 22π

divide both sides by 2

πr = 11π

divide both sides by π

you get r = 11

So your radius is 11.

To find the area, you must do πr^2 ("^2" means squared)

if you substitute 11 for r you get

11π^2

you can do 11 squared first

11^2 = 121

the area of the circle = 121π

Keep in mind that they said to use 3.14 for π

so you can do 121 x 3.14

Final Answer: 379.94
