Lucy rolls 2 fair dice and adds the results from each. Work out the probability of getting a total that is a multiple of 5
Sergio039 [100]

Answer:

(1,4) ( 4,1)  (2,3) (3,2)

Step-by-step explanation:

Multiples of 5  =  5  and 10

Ways to roll a 5  =  (1,4) ( 4,1)  (2,3) (3,2)

Ways to roll  a 10   =  (5,5) (4,6) (6,4)

We have  7  possible outcomes for a multiple of 5...and there are   36  possible outcomes in total

So  P (multiple of 5)    = 7 / 36

The data set gives the number of hours it took each of the 10 students in a cooking class to master a particular technique.
mafiozo [28]

I would say it is either median or mode. Both are basically unaffected by outliers. For median, order them smallest to largest. 3,3,4,4,4,5,5,5,5,30. The median is the middle number, or 4.5 because there is an even amount of numbers, and 4.5 is between 4 and 5. The mode is 5 because it occurs the most. I would use the median, but it is completely up to you.

suter [353]

Answer:

f(1) = 1

Step-by-step explanation:

To evaluate a function, you see the y value it gives when you plug in the x value.
