The estimate for the total population size is 1600.
Setting up a proportion for this, we know that 150 out of our 300 turtle sample is marked; this is the first ratio for the proportion. We also know that we marked 800 of our total population, which we will call x:
150/300 = 800/x
Cross multiply:
150*x = 300*800
150x = 240000
Divide both sides by 150:
150x/150 = 240000/150
x = 1600
the correct answer would be 4 3/4
hope this helps!
lmk if you would like an explanation! :)
Answer:
False.
Step-by-step explanation:
Integers are numbers in this set:
{...,-3,-2,-1,0,1,2,3,...}
The opposite of a number is you just changing the sign of that number. Unless you are asking for the opposite of 0 which is just 0.
Example: The opposite of 5 is -5.
Example: The opposite of -5 is 5.
So the opposite of an integer does not always mean the result will be negative. As you seen above, it could be 0, positive, or negative.
The model is p(x) = 75,000 ∛(x - 1940)
Now use p(x) = 245,000 and solve for x
245,000 = 75,000 ∛(x - 1940) =
245,000 / 75,000 = ∛(x - 1940)
49/15 = ∛(x - 1940)
x - 1940 = [49/15]^3 = 34.86
x = 1940 + 34.86 = 1974.85
Then, the answer is 1975 (option b)
Answer:
120;60
Step-by-step explanation:
The measure of an angle is equal to twice the measure of its supplement.
This means that x = 2(180-x)
<em>Simplify</em>
x = 360 -2x
<em>Isolate the variable</em>
3x = 360
x = 120
This makes its supplement 60
