Answer: 2, 9, 14, 17, 19

Step-by-step explanation:

A box plot uses the values: minimum, maximum, median, first quartile and third quartile.

First sort the data from lowest to highest.

2,8,9,11,14,15,17,19,20

Thus, the minimum, or Data Point 1 is 2.

Then find the median.

8,9,11,14,15,17,19

9,11,14,15,17

11,14,15

Thus, the median, or Data Point 3 is 14.

For the 1st and 3rd quartile, simply, ignoring the median, find the median of the first and second half of the data.

8,9,11

Thus, the first quartile, or Data Point 2 is 9.

15,17,19

17.

Thus, the third quartile, or Data Point 4 is 17.

The maximum of the data, or Data Point 5 is 19.

Which of the following parametric equations are equivalent to the polar equation r=3 cos theta

Allushta [10]

To solve the problem you must know that to change from Cartesian to polar coordinates you must write:
x = rcos (θ)
Where "r" is the radius
Likewise y = rsin (θ)
Therefore, in the expression r = 3cos (θ) one can write r as:
r = x / cos (θ)
So:
x / cos (θ) = 3cos (θ)
x = 3cos ^ 2 (θ)
The same for y ...
y = rsin (θ)
y = 3cos (θ) sin (θ).

Finally the correct answer is option 2.
x = 3cos ^ 2 (θ) y = 3cos (θ) sin (θ).

Suppose we want to divide the 10 dogs into three groups, one with 3 dogs, one with 5 dogs, and one with 2 dogs. how many ways ca

garri49 [273]

Answer:

420 ways

Step-by-step explanation:

According to the given statement:

We want to divide the 10 dogs into three groups, one with 3 dogs, one with 5 dogs, and one with 2 dogs. How many ways can we form the groups such that fluffy is in the 3-dog group and nipper is in the 5-dog group.

In this way we have 8 dogs left.

2 spaces left in 3 dogs group

4 spaces left in 5 dogs group

and 2 spaces in 2 dogs group

Therefore:

= 8!/2!4!2!

= 8*7*6*5*4*3*2*1/2*4*3*2*2

= 8*7*6*5/2*2

= 1680/4

=420

It means there are 420 ways to from the groups....

When mushrooms are dried, they lose 80 percent of their mass. What weight of mushrooms must be picked to get 1 kg of dry mushroo

kaheart [24]

Answer:

We need to start with 5 kg of mushrooms

Step-by-step explanation:

The total of the dried mushrooms = mushrooms * percentage of weight kept

percentage of weight kept = 1- 80% = 20 %

We want 1 kg of dried mushrooms. Substitute in what we know

1 kg = mushrooms * 20%

1 kg = mushrooms * .2

Divide each side by .2

1 /.2 = mushroom *.2 /.2

5 kg = mushrooms

We need to start with 5 kg of mushrooms
