Answer:

  32/225 ≈ 0.1422

Step-by-step explanation:

If you consider "3-digit" numbers to be between 100 and 999, inclusive, there are 128 such numbers divisible by 7. The probability of choosing one at random is ...

  128/900 = 32/225 = 0.1422...(repeating)

__

If you consider all non-negative integers less than 1000 to be "3-digit numbers," then the probability is ...

  142/1000 = 0.142 (exactly)

Someone pls help me I'm really struggling and the assignment is almost due
Grace [21]

Answer:

x<3 and x≥5

Step-by-step explanation:

Look at the circles and what is shaded on the number line.  The first circle is at x=3, and it's an open circle.  An open circle means that the interval does not include that point.  The arrow is going to the left, meaning x < 3.

The next circle is at x=5.  It is a closed circle, so the interval does include that point (so draw a bar under the less than/greater than sign).  Next, notice how the arrow is pointing to the right.  That means that the blue area is at x=5 and greater than x=5, so x≥5.

A population of 200 animals has a growth rate of 1.03% each year. at this growth rate, the function f(x)=200(1.03)^x gives the p
Y_Kistochka [10]
For this case, the first thing we should do is use the following equation:
 f (x) = 200 (1.03) ^ x
 We substitute f (x) = 300:
 300 = 200 (1.03) ^ x
 We clear the value of x:
 log1.03 (300/200) = log1.03 ((1.03) ^ x)
 x = log1.03 (300/200)
 x = 13.72
 Answer: 
 the population will first reach 300 in about 13.72 years.

Hey ! Can anyone help me solve these problems please. Thank you !
devlian [24]
The answer to solve these problems is that the full circle is 360 degrees, the way to find the answer is to have to equal sides that equal 360 degrees. That means one half of 360 degrees is 180 degrees. Hope this helps.
