put a 1 under the 13, so it is 13/1, and 5 5/6, turn it into an improper fraction by multiplying 5x6=30. then 30+5, which is 35. so just keep the denominator, which would be 35/6. so you would have 13/1 - 35/6. you need the same denominator, so see what both 1 and 6 would fit into. which is 6. so 13x6 which is 78, so 78/6 - 35/6, so 78-35 is 43. so 43/6, then simplify, which is 7 1/6

Answer:

The probability of picking 1 red candle followed by another red candle is 16.66%.

Step-by-step explanation:

Since Alfred draws candles randomly from a pack containing 4 colored candles of the same shape and size, and there are 2 red candles, 1 green candle, and 1 blue candle, and he draws 1 candle and then draws another candle without replacing the first one, to find the probability of picking 1 red candle followed by another red candle, the following calculation must be performed:

2/4 x 1/3 = X

0.5 x 0.333 = X

0.16666 = X

Therefore, the probability of picking 1 red candle followed by another red candle is 16.66%.

Can anybody help with this?

Ainat [17]

Answer:

a. 3

b. [5,6]

c. $Median=\frac{n}{2}$

d.Game theory to predict future outcomes based on past results.

Step-by-step explanation:

a. Median is defined as the middlemost data point in a data set of data points arranged in a ranking order.

-Arranging our data points in Ranking order:

0,0,1,1,2,2,3,5,5,5,6,8,8

-Our set has 13 entries. The 7th term is the median Value.

#Hence, the median value of our data set is 3

b. Increasing the median value by 2. And let x and y be the two new scores

-From a above, median is 3:

$M_n=M_{old}+2=3+2\\\\=5$

-The new median value is 5. Adding two data points, makes the 8Th term the median value.

-Given that values of 5 was originally the 8th term, For the median value to be 5,both x and y have to have a value of 5, or one must be a 5 and the next a higher value:

-Hence, [5,6], 5,5] are both possible pairs of x and y

c. From the definition of median in a above,

#If the data points are an odd number of entries, then the median value is (n/2)+1, hence a whole number.

$Median=\frac{n}{2}+1$

#If the data points are an odd number of entries, then the median value is (n/2), hence a decimal number e.g 2.5:

$Median=\frac{n}{2}$

d. Using game theory, real-world scenarios for such situations asruns in baseball games can be predicted from past outcomes.

-As such, we can predict that the next two games are likely to be in the range of the first 13 scores.

Kruka [31]

(a) The percentage of married couple households that are one native, one foreign is 7.3%

(b) The number of married couple households that are one native, one foreign is 4,051,500

(a) Percentage =100%-(79.5%+13.2%)

Percentage =100%-92.7%

Percentage =7.3%

(b)Number of married couple households =7.3%*55,500,000

(b)Number of married couple households =4,051,500

Inconclusion:

(a) The percentage of married couple households that are one native, one foreign is 7.3%

(b) The number of married couple households that are one native, one foreign is 4,051,500

Write answer using listing method

Vlada [557]

Using listing method the elements in the set are +2 and -2.

What is listing method ?

The listing approach involves writing the members of the set as a list, with commas separating the items and curly brackets enclosing the list. The rule or condition that may be used to determine if an object can belong to the set is specified when using the rule method for sets.

The members of a set are listed using this technique, with commas used to separate them and curly braces used to enclose the list. The four distinct seasons, for instance, can all be written as "Summer, Autumn, Spring, and Winter." The list's elements can be in any order, so don't worry.

We are given the set $\left\{x \mid x^2=4\right\}$

all such x such that the perfect square is 4. Now, we have

$x^2=4 \Rightarrow x=\pm 2$

Therefore, the elements in the set are +2 and -2.
