Jake tossed a paper cup 50 times and recorded how it landed. The table shows the results:
JulsSmile [24]

Answer:

0.06 = 6% probability of landing open side up.

0.14 = 14% probability of landing closed side up.

0.8 = 80% probability of landing on its side.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes. For an experimental probability, these numbers are taken from previous trials.

Landing open side up:

3 out of 50, so:

p = \frac{3}{50} = 0.06

0.06 = 6% probability of landing open side up.

Landing closed side up:

7 out of 50, so:

p = \frac{7}{50} = 0.14

0.14 = 14% probability of landing closed side up.

Landing on its side:

40 out of 50, so:

p = \frac{40}{50} = 0.8

0.8 = 80% probability of landing on its side.

Which expression represents x^2+8x+16? <br>​
salantis [7]

Answer: C

Step-by-step explanation:

To factor a trinomial, you need to multiply 'a' and 'c' and see what two number add to equal 'b' but also multiply to equal the product of 'a' and 'c'.

So, what two numbers multiply to equal 16 but simultaneously add to equal 8?

That is +4 and +4. Instead of writing (x+4)(x+4), you can write (x+4)^2, or answer C.

Please help me solve this ;-;
Digiron [165]

9514 1404 393

Answer:

  C  log3(√((x -4)/x)

Step-by-step explanation:

The applicable rules of logarithms are ...

  log(a/b) = log(a) -log(b)

  log(a^n) = n·log(a)

The base is irrelevant, as long as all logs are to the same base.

__

  \dfrac{1}{2}(\log_3{(x-4)}-\log_3{(x)})=\dfrac{1}{2}\log_3(\dfrac{x-4}{x})=\boxed{\log_3\left(\sqrt{\dfrac{x-4}{x}}\right)}
