Answer:
7√2 units
Step-by-step explanation:
The distance between two points having coordinates (x1, y1) and (x2, y2) is given by,
Here, x1=-4 and y1=2
x2=3 and y2=-5
-34(x+2)=6
Distribute the -34
x(-34) +2(-34)=6
-34x-68=6
Add 68 to both sides
-34x-68+68=6+68
-34x=74
Devide both sides by -34
x=-37/17
x= 2 3/17
Answer: X= -5
Step-by-step explanation:
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
