Fill in x=19 and you get:

$f(19) = \frac{3}{19+2} - \sqrt{19-3} = \frac{3}{21} - \sqrt{16} = \frac17 - 4 = -3\frac67$

Just replace x by 19==> f(19) = 3/(19+2) - √(19-3) ==> 3/21 - √16

3/21 - √16 = 3/21 - 4 . Reduce to same denominator f(19) =- 81/21 or -27/7

WILL GIVE BRANLIEST HELP PLEASE!

I believe since you are looking for the angle of M<ABC, you just add both 120 and 25 together, since they practically share a point.

So 120 + 25 = 145

So I guess 145 would be your answer.

I remembered this type of problem from Geometry.

The formula for the size of a file that was downloaded over time t and at an average rate r is r.t.

lakkis [162]

Answer:

The size of file downloaded is 88 megabytes.

Step-by-step explanation:

Given that:

Average rate of downloading the file = $r$

Time taken to download = $t$

Formula for the size of file downloaded = $r.t$

Rate of downloading, $r = 800\ kilobytes/sec$

Time taken, $t$ = 110 seconds

To find:

Size of file downloaded in megabytes = ?

Solution:

First of all, let us apply the given formula to find the size of file downloaded:

Size of file downloaded = $r.t$

Size of file downloaded = 800 kilobytes seconds $\times$ 110 seconds =

88000 kilobytes.

Now, let us convert the unit kilobytes to megabytes to find the answer.

Conversion formula:

1000 kilobytes = 1 megabyte

Let us use unitary method to find the number of megabytes in 88000 kilobytes.

1 kilobytes = $\frac{1}{1000}$ megabytes

88000 kilobytes = $\frac{1}{1000} \times$ 88000 megabytes

$\Rightarrow$ 88 megabytes.

Therefore, the size of file downloaded is 88 megabytes.

Malcolm has been watching a roulette-style game at a local charity bazaar. The game has only ten numbers on the wheel, and every

Mariana [72]

Answer:

Malcolm is showing evidence of gambler's fallacy.

This is the tendency to think previous results can affect future performance of an event that is fundamentally random.

Step-by-step explanation:

Since each round of the roulette-style game is independent of each other. The probability that 8 will come up at any time remains the same, equal to the probability of each number from 1 to 10 coming up. That it has not come up in the last 15 minutes does not increase or decrease the probability that it would come up afterwards.
