Rhonda manages wildlife samples for Ducks Unlimited. Two samples of duck populations at a migratory site are shown in the table below. Which statement about the samples is true? Duck Pond Samples Sample 1 Sample 2 Mallard 19 Mallard 38 Wood Duck 3 Wood Duck 1 Green Wing Teal 10 Green Wing Teal 1 American Widgeon 8 American Widgeon 0 Rhonda needs to continue taking samples of ducks until both samples have at least one of each type of duck. Rhonda should take a third sample and then use the two that are most representative since these samples vary quite a bit. Rhonda should use both of these samples as they are to make inferences about the average population of each type of duck in the pond. Both samples must be biased because there are more Mallards than any other type of duck recorded in the sample.

Answer:

b; 1 real root and 2 imaginary roots

Step-by-step explanation:

From here, we have

x(x^2 + 121) = 0

x = 0 (1 real root)

or

x^2 + 121 = 0

x^2 = -121

x = √(-121) (2 imaginary roots)

so is would be two complex numbers from above

Answer:

-64

Step-by-step explanation:

-16+-16+-16+-16=-64

Answer:

[tex] - 64[/tex]

Step-by-step explanation:

Ignore any negative sign for now.

[tex]16 \times 4[/tex]

Use the algorithm method.

1 6

× 4

______

6² 4

Now consider the signs. One number is positive, and the other number is negative. Therefore, the result will be negative.

[tex]16. \: - 4 = > negative[/tex]

Therefor, 16 × -4 = -64

[tex] - 64[/tex]

Answer: 3:08

Step-by-step explanation:

They started riding at 2:47 and reached the soccer field 21 minutes later.

The time they go to the field is therefore:

= 2:47 + 21 minutes

= 3:08

Adding time:

First find out the number of minutes needed to take 2:47 to 3:00:

= 60 minutes in an hour - 47

= 13 minutes

Then remove the 13 minutes from the 21 minutes of riding:

= 21 - 13

= 8 minutes

Add this 8 to 3:00:

= 3 + 8

= 3:08

The descriptions that apply to a coordinate plane are:

a) Cartesian plane

b) Two-dimensional

d) Extends forever

e) Perpendicular axes.

The descriptions that apply to a coordinate plane are:

Cartesian plane: A coordinate plane is often referred to as a Cartesian plane, named after the mathematician René Descartes, who introduced the concept of using coordinates to represent points in space.

Two-dimensional: A coordinate plane is a two-dimensional space where points are represented using two perpendicular axes (usually labeled as x-axis and y-axis).

Extends forever: The coordinate plane extends infinitely in all directions along the x-axis and y-axis, allowing representation of points with arbitrary coordinates.

Perpendicular axes: The two axes in a coordinate plane are perpendicular to each other, intersecting at the origin (0, 0). The x-axis is horizontal, and the y-axis is vertical.

The description "Three-dimensional" does not apply to a coordinate plane. A coordinate plane is a two-dimensional space, and it does not have a third axis to represent points in three dimensions.

In a three-dimensional space, you would need an additional axis (usually labeled as z-axis) perpendicular to the x-axis and y-axis to represent points in three dimensions.

Hence, The descriptions that apply to a coordinate plane are:

a) Cartesian plane

b) Two-dimensional

d) Extends forever

e) Perpendicular axes.

Answer: -7

Step-by-step explanation:

From the information given, we are.l told that Oscar's elevation change after 12 minutes was -84 feet.

Since his elevation was changing at a constant rate, his elevation change per minute will be:

= -84 feet / 12

= -7feet/minutes

Therefore, the integer is -7.

Answer: (c)

Step-by-step explanation:

Given

Function [tex]f(x)[/tex] is [tex]3\times 2^x-3[/tex]

Also, [tex]g(x)[/tex] is the transformation of [tex]f(x)[/tex]

From the graph, it is clear that [tex]g(x)[/tex] passes through the point [tex](0,5)[/tex]

Now check the option which satisfies the condition

option (c) seems to obey it

[tex]g(x)=3\cdot 2^x+2\\g(0)=3\cdot 2^0+2\\g(0)=3\cdot 1+2\\g(0)=3+2\\g(0)=5[/tex]

Therefore, option (c) is correct.

Answer:

Step-by-step explanation:

The function for this problem is: h(t) = -16(t)^2 + vt + s h= the height t= time v= velocity s= starting height With the information given, we know that the starting height is 0, since it was from the ground, and the velocity of the ball is 35 feet per second. Inserting the these information into the equation, we get: h(t) = -16(t)^2 + 35t Now the question asks to find the maximum height. It can be done by using a grapher to graph the maximum of the parabola. It could also be done by finding the vertex, which would be the maximum, of the graph by using x= -b/(2a), where b is equal to 35 and a is equal to -16. We get x=35/32, the x-value of where the vertex lies. You can use this value as the t-value in the previous equation to find the h-value of the vertex. When you do, you get h= 19.1 feet, or answer D.
