I believe the correct answer would be perfect negative association. It is describe as perfect since the points reflects an almost linear graph or relation. It is  negative since as Y increases, the value of X decreases or vice versa. Hope this answers the question.

If we collect a large sample of blood platelet counts and if our sample includes a single​ outlier, how will that outlier appear
Mademuasel [1]
That outlier will appear as a single blip of data, but it will be far away from the central part of the histogram. It will not be that visible if there is a lot of data, since 1 outlying data point will just show a very low height compared to the central data near the mean/median/mode, where there will be higher frequencies and higher bars of data.

If these are the choices:
<span>A.The outlier will appear as a tall bar near one side of the distribution.
B.The outlier will appear as a bar far from all of the other bars with a height that corresponds to a frequency of 1.
C.Since a histogram shows​ frequencies, not individual data​ values, the outlier will not appear.​ Instead, the outlier increases the frequency for its class by 1.
D.The outlier will appear as the tallest bar near the center of the distribution.
</span>
Then the most accurate answer will be B, since it's just a single value with a bar corresponding to a frequency of 1.

The ratio of the perimeter of a square to the length of a rectangle is 5:6.
pav-90 [236]

Answer:

=225/16cm^2

Step-by-step explanation:

Given

The ratio of the length to the width of the rectangle =3:2.

The perimeter of a rectangle = 60cm.

Solution

Let length=3x

width=2x

Perimeter of rectangle=2(length + width)

2(3x+2x)=60

5x*2=60

10X=60

X=60/10

X=6

SO LENGTH =3×6=18cm

WIDTH=2×6

=12cm

Let perimeter of the square=5x

Length of rectangle=6x

6x = 18

X=18/6

X=3

SO PERIMETER OF SQUARE=5×3

4SIDE=15

Side=15/4

Area of square=15/4×15/4

=225/16cm^2

Prove that it is impossible to have $4.50 in dimes and quarters with the number of quarters being twice the number of dimes
SOVA2 [1]

Answer:

See Explanation below for proof.

Step-by-step explanation:

Let number of dimes be D

Then number of quarters = 2D  

We then get the following VALUE equation: .1D + .25(2D) = 4.5

.1D + .5D = 4.5

.6D = 4.5

D, or number of dimes = 4.5/.6 = 7.5

There is no such thing as HALF a DIME, so it's NOT POSSIBLE
