Answer:
C. 12/15
Step-by-step explanation:
2/3, 6/9, and 18/27 all simplify to 2/3. 12/15 does not.
Answer:
3/5, 30%, 0.1
Step-by-step explanation:
0.4 + 1/2 + 40% = 0.4 + 0.5 + 0.4 = 1.3
3/4 + 0.25 + 1/2 = 0.75 + 0.25 + 0.5 = 1.5
3/5 + 30% + 0.1 = 0.6 + 0.3 + 0.1 = 1
The last choice is a probability complement because all values add to 1.
Answer:

Step-by-step explanation:
The logistic function of population growth, that is, the solution of the differential equation is as follows:

We use this equation to find the value of r.
In this problem, we have that:

So we find the value of r.






Applying ln to both sides of the equality


So
The differential equation is

16<2(3x-1)<28 divide all terms by 2
8<3x-1<14 add 1 to all terms
9<3x<15 divide all terms by 3
3<x<5
x=(3,5) in interval notation
On a number line, it would be a line segment from 3 to 5 with open circles at 3 and 5.
On a coordinate system graph, it would be an infinitely high shaded plane between the vertical lines x=3 and x=5
Answer:
54
Step-by-step explanation:
The square in the middle = 36, as 6x6=36
There are 2 triangles on each side of the center square.
Since the base of the trapezoid is 12, and the base of the square is 6, that leaves 3 for the base of each triangle.
3x6=18x1/2 (As a triangle's area is b (base) x h (height) x (one half) 1/2
18x1/2 is 9.
Each triangle equals 9.
36+9+9=54
The final answer is 54
