Manatees are an endangered species of herbivorous, aquatic mammals found primarily in the rivers and estuaries of Florida. As part of its conservation efforts, the Florida Fish and Wildlife Commission records the cause of death for every recovered manatee carcass in its waters. Of the 392 recorded manatee deaths in 2012, 68 were perinatal and 81 were caused by collision with a watercraft.
Required:
a. What is the probability that the death of a randomly selected manatee was due to collision with a watercraft?
b. What is the probability that the death was not due to collision with a watercraft?
c. What is the probability that the cause of death was due to perinatal problems or collision with a watercraft?
Answers
Answer:
a) 0.206 , b) 0.794 , c) 0.38
Step-by-step explanation:
a) Prob(watercraft collision death)= Watercraft collision deaths / Total deaths = 81 / 392 = 0.206
b) Prob (Death non watercraft collison) = 1 - Prob (Death watercraft collision) = 1 - 0.206 = 0.794
c) Prob (Prenatal or watercraft collision death) = (68 + 81) / 392 = 0.38

Find the discriminant and the num

A. 28; two real roots
Answers
Answer:
Discriminant = -24, no real roots.
Step-by-step explanation:
The discriminant is what's inside the square root in the quadratic formula.
The quadratic formula is:
[tex]\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex] and [tex]\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex]
a = 1
b = 2
c = 7
The question wants the discriminate, we can just focus on the square root part.
When we plug in the parts we got, it becomes:
[tex]\sqrt{4-4(1)(7)}\\\sqrt{4-28} \\\sqrt{-24}[/tex]
Since the inside of the square root is negative, there are no real roots.

Step-by-step explanation:
Dado que un taxi viaja a una velocidad de 48 mph para llegar a un destino en 2 horas y media, para determinar cuál seria su velocidad si se tarda dos horas para llegar se debe realizar el siguiente cálculo:
48 x 2.5 = 120
120 / 2 = X
60 = X

If f(1)=6 and f(n)=f(n-1)+2 then find the value of f(6)
Answers
Answer:
Step-by-step explanation:
Answer:
f(6) = 16
Step-by-step explanation:
In the next steps we use this formula : f(n)=f(n-1)+2
Since f(1)=6 then f(2)=f(2-1)+2 = f(1)+2 = 6+2 = 8
f(2)=8 then f(3)=f(3-1)+2 = f(2)+2 = 8+2 = 10
f(3)=10 then f(4)=f(4-1)+2 = f(3)+2 = 10+2 = 12
f(4)=12 then f(5)=f(5-1)+2 = f(4)+2 = 12+2 = 14
f(5)=14 then f(6)=f(5-1)+2 = f(4)+2 = 14+2 = 16.

By using trigonometric relations we will see that the area is:

How to find the area of one triangular section?
Remember that the area of a right triangle is equal to the product between the cathetus divided by 2.
Sadly, here we don't have the measures of any sides of the triangle, so getting the actual area is impossible, but if we assume that some dimension is given (like the height, let's say that is h).
h is the cathetus adjacent to the 60° angle, then the other cathetus (the bottom one) is given by:
tan(60°) = x/h
x = tan(60°)*h
Then our two catheti are h and tan(60°)*h.
This means that the area will be:
[tex]A = h*tan(60\°)*/2 = tan(60\°)*h^2/2[/tex]
Here we only used trigonometric properties, so this area will work for any height given (always that the value of h is the cathetus adjacent to the 60° angle).

A: –10 or less
B: –10 or greater
C: 12 or less
D: 12 or greater
Answers
ANSWER:
D) 12 or greaterStep-by-step explanation:
Total money Charnika has = $500
The money she wants to save = $200
Amount of money she can spend = $ (500 - 200)
= $300
Amount of money withdrawn in every week = $25
The number of weeks the money can be withdrawn = $ (300÷25)
= $ 12

ONM has vertices O (-4, 2), N (3, 6) and M(0,3). What are the coordinates of the
vertices of O' N' M' if ONM is first translated (x, y)+(x + 3, y) followed by a
reflection across the line y = 1?
Answers
Answer:
The new vertices are [tex]O''(x,y) = (-1, 0)[/tex], [tex]N''(x,y) = (6,-4)[/tex] and [tex]M''(x,y) = (3,-1)[/tex].
Step-by-step explanation:
Previously, we have to define a vectorial equation for a reflection across the line [tex]y = 1[/tex]:
Reflection across the line y = 1:
[tex]P'(x,y) = P(x,y) -2\cdot [P(x,y) -(x_{P},1)][/tex] (1)
Where:
[tex]P(x,y)[/tex] - Original point.
[tex]x_{P}[/tex] - x-Coordinate of the original point.
[tex]P'(x,y)[/tex] - Resulting point.
Translation:
[tex]P'(x,y) = P(x,y) + (3,0)[/tex] (2)
If we know that [tex]O(x,y) = (-4,2)[/tex], [tex]N(x,y) = (3, 6)[/tex] and [tex]M(x,y) = (0,3)[/tex], then the resulting points are, respectively:
Point O'
Translation
[tex]O'(x,y) = O(x,y) + (3,0)[/tex]
[tex]O'(x,y) = (-1,2)[/tex]
Reflection
[tex]O''(x,y) = O'(x,y) -2\cdot [O'(x,y) -(x_{O'},1)][/tex]
[tex]O''(x,y) = (-1,2) -2\cdot [(-1, 2)-(-1,1)][/tex]
[tex]O''(x,y) = (-1, 0)[/tex]
Point N'
Translation
[tex]N'(x,y) = N(x,y) + (3,0)[/tex]
[tex]N'(x,y) = (6,6)[/tex]
Reflection
[tex]N''(x,y) = N'(x,y) -2\cdot [N'(x,y) -(x_{N'},1)][/tex]
[tex]N''(x,y) = (6,6) - 2\cdot [(6,6)-(6,1)][/tex]
[tex]N''(x,y) = (6,-4)[/tex]
Point M'
Translation
[tex]M'(x,y) = M(x,y) + (3,0)[/tex]
[tex]M(x,y) = (3,3)[/tex]
Reflection
[tex]M''(x,y) = M'(x,y) -2\cdot [M'(x,y) -(x_{M'},1)][/tex]
[tex]M''(x,y) = (3,3) - 2\cdot [(3,3)-(3,1)][/tex]
[tex]M''(x,y) = (3,-1)[/tex]
The new vertices are [tex]O''(x,y) = (-1, 0)[/tex], [tex]N''(x,y) = (6,-4)[/tex] and [tex]M''(x,y) = (3,-1)[/tex].
