Braden wants to compare the types of ducks in two nearby ponds. He collected two samples using the following criteria. For sampl

e 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 pond

What is exactly the relation between a Rhombus, rectangle, parallelogram, and square explain please i will mark brainliest only
ch4aika [34]

Any rhombus is a parallelogram, but not the other way around. If you were to make a Venn Diagram, the "rhombus" portion is entirely inside the set of "parallelograms".

The same can be said about rectangles as well. Any rectangle is a parallelogram, but not the other way around.

If we overlapped the region of rectangles and rhombuses, then we form the region for squares. A square is a combination of a rhombus and a rectangle.

Any square has all four sides the same length (property of a rhombus) and all angles equal to 90 (property of a rectangle). Since a square inherits properties of a rectangle and rhombus, it automatically makes any square a parallelogram.

Check out the venn diagram below.

Which of the following represents a negative correlation?
babunello [35]

Answer:

The answer is letter B, The water level in a bathtub as it drains over time.

Step-by-step explanation:

It is best to learn the meaning of <u>"negative correlation"</u> first.

Correlation- In Mathematics, "correlation" means a measure of the relationship between two variables.

<em>Positive Correlation-  </em>when the values of the variables increase together.

<em>Negative Correlation- </em>when one value of a variable increases while the other variable's value decreases.

*The situation above is asking for a negative correlation, therefore the answer is letter B (The water level in a bathtub as it drains over time).

The variables are: <u>water level and draining time</u>

As the draining time increases, the water level in the bathtub decreases. This is clearly an example of a negative correlation.

HELP I NEED THIS DONE NOW!
SashulF [63]

Answer:

-3.8 - (7.2-10 3/8)

-3.8+(-7.2+10 3/8) this is the error, it's positive 10 3/8, not negative, then you should solve what's in the parentheses first

I simplified 10 3/8 into 83/8 and then 10.375

-3.8+(-7.2 + 10.375)

-3.8+ 3.175 = -0.625
