Probabilities with Rocks

Mathematics
1 answer:
vovikov84 [41]4 years ago
3 0

Answer:

Step-by-step explanation:

Our Sample size is 42 rocks total.  If we want to pick one red rock out of the 42, we first have to determine the possibility of doing that from the numbeer of red rocks we have total.  There are 6 red rocks, so the probability of picking one of those is

6/42 or 1/7

There are 14 blue rocks.  So the probability of picking one of those is

14/42 or 1/3

There are 22 white rocks.  So the probability of picking one of those is

22/42 or 11/21

gogolik [260]

Answer:

  (c)  8597

Step-by-step explanation:

A tool for regression analysis shows the given population values fit an exponential curve better than they fit a line. The exponential function for the population can be written as approximately ...

  p(x) = 6211.54(1.02998^x) . . . . . x is years after 2000

Then for x=11, the population is about ...

  p(11) ≈ 8596.4

The closest answer choice is 8597.

Find the reference angle of the following angles:405°, 750°, ‒ 210°, 495° ‒660°, 480°
scZoUnD [109]

Answer:

Step-by-step explanation:

405÷180=2×180+45,45°

750=180×4+30,30°

-210+180=-30,30°

495÷180=2×180+135,180-135=45°

-660°+360=-300°+360=60,60°

480-360=120,180-120=60,60°

Which expression is equivalent to log18 – log(p + 2)?
Novosadov [1.4K]

Answer:

log(18/(p+2))

log StartFraction 18 Over p + 2 EndFraction

Second option is the correct.

Step-by-step explanation:

There is a property of logarithms that when two logarithms are subtracting each other, we can make a single logarithm with the argument being the division of their arguments:

log(x) - log(y) = log(x/y)

So, with we have log18 – log(p + 2), we can rewrite as:

log18 – log(p + 2) = log(18/(p+2)), that is:

log StartFraction 18 Over p + 2 EndFraction

Second option is the correct.
