Since there are two minus sign with the two, make it into plus. There fore the equation is -10+2= -8!
b. Consider a large population of turtles in which 30% of the population are snapping turtles and 70% of the population are box turtles. What is the value of the diversity index D for the population
Answer: the value of the diversity index D for the population is 0.42
Step-by-step explanation:
Given that; population of the two species are
p1 = 30% = 0.3 (snapping turtle)
p2 = 70% = 0.7 ( box turtle)
so if two (2) organisms are picked, then they can be different from each other ( i.e Event E) under following two scenarios
E1 → First organism selected from p1 and second organism selected from p2
E2 → First organism selected from p2 and second organism selected from p1
which means we are observing the different orders in which the organisms can be picked.
So the probability of event E = the sum of probabilities of events E1 and E2.
which is;
D = P(E) = P(E1) + P(E2)
= P1×P2 + P2×P1
= 2P1P2
so we substitute
D = 2 × 0.3 × 0.7
D = 0.42
Therefore the value of the diversity index D for the population is 0.42

Answer:
B (rate of change), D (y-intercept)
Step-by-step explanation:
a) The rate of change is found by solving for y. It is the x-coefficient:
4y = -x +12
y = -1/4x +3 . . . . divide by 4
The rate of change is -1/4.
__
b) The rate of change can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (10 -4)/(2 -(-2)) = 6/4 = 3/2
The rate of change is 3/2.
__
c) The rate of change can be found by counting grid squares. The line goes down 1 square for each square to the right. The rate of change is ...
m = rise/run = -1/1 = -1
The rate of change is -1.
__
d) The rate of change is 0.5, the amount paid per box.
__
Of the rates -1/4, 3/2, -1, 0.5, the largest rate of change is 3/2 in relationship B.
_____
a) The y-intercept is the constant in the slope-intercept form equation: +3.
__
b) The y-intercept can be found from the point-slope form equation using the slope we found.
y -4 = 3/2(x +2)
y = 3/2x +3 +4
y = 3/2x + 7
The y-intercept is 7.
__
c) The y-intercept is 4, where the line crosses the y-axis.
__
d) The y-intercept of a proportion is 0.
__
Of the y-intercepts 3, 7, 4, 0, the least y-intercept is 0, in relationship D.
3+5x-4-7x=2x-4x+1 i have to solve this problem
Answer:
Undetermined x=x
Step-by-step explanation:
First, you need to simplify each side by combining like terms:
(5x - 7x)(+3-4) = (2x - 4x) +1
-2x - 1 = -2x + 1 is your simplified expression.
After adding 1 to both sides, you're left with: -2x = -2x
You can divide both sides by -2, you'd get: x = x
Therefore, it's undetermined. Meaning, there are no possible solutions or there's infinite solutions. In this case, there's infinite solutions.
A rectangular water tank is 80 m long, 50 m wide and 60 m height. If the
depth of water in the tank is 45 m, find the volume of water required to
completely fill the tank?*
A)240,000cm3
B)60,000cm3
C)180,000cm3
D)120,000cm3
Answer: 2
Step-by-step explanation:
80 x 50 x 60 is volume of tank
240000
Water is already filled to 45 so volume up to that is
80x 50 x 45 = 180000
Subtract to find the difference needed to fill tank
240000 - 180000 = 60000
The volume of water to completely fill the tank is A) 240,000cm³.
What is volume?Volume is defined as the amount of three-dimensional space occupied by some close object.
We know the volume of a cuboid is (Height×Width×Length).
Given a rectangular water tank is 80m long, 50m wide and 60m in height and the depth of the water is 45m.
To obtain the volume of water we have to take 45m as the height or we can think of the height of the tank is 60m but water can only be filled up to 45m.
∴ The volume of the water is (80×50×45) m³.
= 180,000 m³.

A bottle contains 24oz of liquid medication.If the average dose is 2/3oz. How many dose does the bottle contain
Answer:
36
Step-by-step explanation:
keep, flip, change...
24 ÷ [tex]\frac{2}{3}[/tex] would be the same as [tex]\frac{24}{1}[/tex] × [tex]\frac{3}{2}[/tex] which is equal to [tex]\frac{72}{2}[/tex] (36 if you simplify it)
The number of dose of 2/3oz of liquid medication does the bottle contain is 36.
What is the fraction number?Fraction number is the number which is a part of a whole number. It is written with a numerator and denominator. Fraction number are written as,
[tex]\dfrac{a}{b}[/tex]
Here (a) is the numerator and (b) is the denominator.
A bottle contains 24oz of liquid medication and the average dose is 2/3oz.
Let suppose the number of dose does the bottle contain is n. There is total 24oz of liquid medication in the bottol.
As the average dose is 2/3oz. Thus the number of dose in the bottle which has 24oz of liquid medication is,
[tex]n=24\div\dfrac{2}{3}\\n=24\times\dfrac{3}{2}\\n=36[/tex]
Thus, the number of dose of 2/3oz of liquid medication does the bottle contain is 36.

Solve the equation by graphing. - x2 = 8x + 20
Answer: No real solutions.
Step-by-step explanation: −x2=8x+20
Step 1: Subtract8x+20 from both sides.
−x2−(8x+20)=8x+20−(8x+20)
−x2−8x−20=0

The width of the rectangle is 40% of its length. What is the area of the rectangle?
A rectangle. The length is 20 feet.
Answer:
160in²
Step-by-step explanation:
40% = 0.4 = 4/10
The length is 20, 40% of that is (0.4)(20) = 8in
Length * width . = 20*8 = 160in²
The width of the rectangle is equal to 8 feet.
What is the area of the rectangle?The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the rectangle in a two-dimensional plane is called the area of the rectangle.
The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that the width of the rectangle is 40% of its length.
