What is the median of the data set? {23, 19, 20, 17, 22, 15, 25, 18, 17, 18, 24, 21}

Answers

Answer 1

Answer: First put the numbers in order, least to greatest.
15, 17, 17, 18, 18, 19, 20, 21, 22, 23, 24, 25
Count the amount of number in the data set. In this one there is 12. Since 12 is an even number, the media will not be in the data set because there is no possible way to have the same amount of numbers on each side. SO, count 6 numbers in to the data set (which would be 19). Next to that is 20. Add 19+20=39. Divide 39 by 2 (2 numbers), which is 19.5
The median of this data set is 19.5
Hope I helped :)

Answer 2

Answer: The median of the set is 19.5

I feel uncomfortable at having been bamboozled. You sent me
a message saying you wanted me to "check" your math work.
Sadly, the truth is that you haven't necessarily tried any of these,
and there's nothing to "check". What you really want from me is
just the answers.

1). 62,000,000 = 6.2 x 10⁷

2). -3.05 x 10⁶ = -3,050,000

3). 0.00000089 = 8.9 x 10⁻⁷

4). (9.8 x 10²) x (5.9 x 10⁷) = (9.8 x 5.9) x (10²⁺⁷) =

      57.82 x 10⁹ =

   5.782 x 10¹⁰ .

a spinner marked with four sections blue, green, yellow, and red was spun 100 times. find the experimental probability of landing on green

Answers

1/4 because it a possibilty of how many times you'll get it on green

Answer:

1/4

Step-by-step explanation:

Okay so there are 4 different colors and you are spinning it 100 times.

Green is one of the for colors so the probability is 1/4

but the denominator for now must be 100

What is 1/4 of 100 ?

25.

So the probabiltiy is 25/100 but you need to reduce so it would be 1/4

60 paintings. T= Painting from 20th century. B= British painting. A painting is chosen random.it is from the 20 century. Work out the probability it is British

Answers

The probability will be "0.20".

According to the question,

The sum of all the areas = 60

then,

$x(x-2)+x+(2x+8)+10=60$
$x=6$

Therefore,

→ $P (British | It's \ from \ the \ 20^(th) \ century) = (n(B \ and \ T))/(n(T))$

$= (x)/(x+x(x-2))$

$= (6)/(6+6(6-2))$

$= (1)/(5)$

$= 0.20$

Thus the answer above is right.

Final answer:

This question is about computing the conditional probability that a painting selected at random is British, given it's from the 20th century. Without specific numbers, the tentative solution is the ratio of the number of British 20th-century paintings to the total number of 20th-century paintings.

Explanation:

The subject here is Probability, a topic within Mathematics. Let us assume without losses in generality that 'T' represents a painting from the 20th century and 'B' represents a British painting. Given 60 paintings, we're selecting one at random. The condition is it's a 20th-century painting ('T') and we need to find the probability that it's also a British painting ('B'). The data given in the question isn't clear enough to give a numerical answer. However, we can give a general solution.

Firstly, we find the number of paintings which are both from 20th century and British. Let's say this number is n. The number of 20th-century paintings would be more than or equal to n. Let's call this N. Therefore, the required probability would be n/N.
