Braden wants to compare the types of ducks in two nearby ponds. He collected two samples using the following
criteria. For sample 1, he counted the types of ducks on Walden Pond from 6 A.M. to 9 A.M. For sample 2, he counted
the number of Mallard ducks that were on Brook's Pond from 12 P.M to 3 P.M.
What would improve Braden's plan? Select three options.
Braden should sample the ducks on each pond at the same time of day because animals are active at different
times
Braden should sample twice at each pond if he wants to make sure each sample is representative of the
population
Braden should count more than Mallard ducks on Brook's Pond if he wants to compare the types of ducks on each
pond
Braden should only count Mallard ducks on Walden Pond so he counts the same types of ducks as he does at
Brook's pond.
Braden should include herons and geese in his samples because they also like ponds.

Answer:

X=1÷2,Y=32°

Step-by-step explanation:

in right angled traingleRST

<R+<T<S=180(INTERIOR ANGLE OF TRAINGLE)

Y-2+90+60=180(S=60°BEING ONE ANGLE OF EQUILATERAL TRAINGLE)

Y+148=180

Y=180-148=32

NOW,

UT=5X(RT BISECTS TS AND UT EQUALLY)

RU=US(SIDE OF EQUILITERAL TRAINGLE IS EQUAL)

8X+1=UT+TS

8X+1=5X+5X

1=10X-8X

1=2X

X=1/2

Answer:

B

Step-by-step explanation:

There are a couple of ways you can go about solving this. The first is plotting all of the points and seeing which one makes a straight line. This is a little bit more time consuming but is great if you blank out and forget how to solve it. The faster way to do it is to see which function is decreasing/increase a constant amount between equal intervals. A increases but by a different amount each time. B decreases by 2 each time. C decreases at different intervals each time. And D does not consistently increase or decrease.

18 hours

Step-by-step explanation:

6/10=0.6 hours (one person takes 0.6 hour)

0.6×30=18 hours

or another way 10 is 1/3 of 30. so

6:1/3=18

Answer:

nope

Step-by-step explanation:

The given ratios  5:3 and 6:4 are not equivalent.

Equivalent ratios are the ratios that are the same when we compare them. Example 1/2 and 2/4 are equivalent ratios.

Two or more ratios can be compared with each other to check whether they are equivalent or not.

The given two ratios are 5:3 and 6:4

We can write them as 5/3 and 6/4

Let us apply subtraction, if we get 0 then these are equivalent.

6/4-5/3

The LCM of 4 and 3 is 12

=(18-20)/12

The value of 18-20 is -2

=-2/12

We have to divide 2 by 12 we get -1/6.

=-1/6 not equal to 0

The ratios 5:3 and 6:4 are not equivalent.

Answer:

Yes, your answer is correct.

Answer:

The arrow can be broken into a rectangle and a triangle.

And the area of the arrow is 22 ft^2

Step-by-step explanation:

Area of the rectangle:

length • width = 7 • 2 = 14 ft^2

Area of the triangle:

(base • height) / 2

You must add 1 + 2 + 1 in order to get the base which is 4

And to get the height, you must do 11 - 7 = 4 (height)

(4 • 4) / 2 = 8 ft^2

Add both areas together to get the area of the arrow:

14 ft^2 + 8 ft^2 = 22 ft^2

Hope this helps!

Answer:

Answer:

Richard gets: £9

Andrew gets: £21

Step-by-step explanation:

To get the value of 1 part we have to add the total number of parts (3+7) and then divide them by the sum (30) 30/10 = 3 so we know 1 part is £3

Thus Richard gets: £3*3 = £9

And Andrew gets: £3*7 = £21

Answer:

Please check the explanation.

Step-by-step explanation:

Given

We can determine the area of the rectangular field using the equation

[tex]A=wl[/tex]

where

substituting  l = 240m, and  w = 200m in the formula

[tex]A=wl[/tex]

A = 240 × 200

A = 48000 m²

Given that the cost of digging the field at Rs 10 per m².

Thus,

The cost of digging the field of the area 48000 m² = 10 × 48000

                                                                                     = 480000 Rs

Therefore, the total cost of digging = 480000 Rs

Answer:

The equation is;

y = -2x + 1

the answer belonging in the green question mark is -2

Step-by-step explanation:

We start by getting the slope

The slope can be obtained by selecting any two points and applying the slope formula

let us select the points;

(1,-1) and (3,-5)

the slope formula is;

m = (y2-y1)/(x2-x1)

m = (-5-(-1)/(3-1)

m = (-5+1)/2 = -4/2 = -2

The y intercept is the value of y when x = 0

As it can be seen, y = 1 when x = 0

so the equation of the relation is;

y = -2x + 1
