Can anybody help with this?

a. 3

b. [5,6]

c.

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:

-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.

#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:

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.

3.4 pizzas

step-by-step explanation:

given is a scatter plot showing number of pizzas sold during weeks for different issues of coupon

y represents number of pizzas sold and x number of coupons issued

y is marked verticaly and x horizontally

the trend line is given as

y =3.4x+43

this says that even when no coupon is issued pizzas sold will be 43

and rate of change of pizza sold for 1 unit of coupon = slope = 3.4

i.e. when x increases by 1 unit y increases by 3.4 units

hence for each additional coupon issued 3.4 pizzas more will be sold

98%
