Answer:
Probability of rolling a number greater than 2 = 5/6
Step-by-step explanation:
Given:
Number;
1,2,3,4,5,6,7,8,9,10,11,12
Find:
Probability of rolling a number greater than 2
Computation:
Number greater than 2 = 10
Probability of rolling a number greater than 2 = Number greater than 2 / Total number
Probability of rolling a number greater than 2 = 10 /12
Probability of rolling a number greater than 2 = 5/6
(5,-3), (-7,9) are two possible point coordinates
Answer:
f(3) ≈ 17.310
Step-by-step explanation:
e = 2.71828
Step 1: Define
f(x) = e2x - 1 + 2
x = 3
Step 2: Substitute and evaluate
f(3) = e2(3) - 1 + 2
f(3) = 6e + 1
f(3) = 16.3097 + 1
f(3) = 17.3097
f(3) ≈ 17.310
A) it is left skewed
B) the median is 5
C) the mean is 5.15
D) the mean would be more affected (a change of 1.05 versus a change of 0.5).
The majority of the data is to the right of the graph; this means it is left skewed.
To find the median, write all of the data values out:
2, 3, 4, 4, 5, 5, 5, 6, 6, 6, 7, 7, 7
The middle value is 5.
We find the sum of this set of values and divide by 13, the number of data points, to find the mean:
2+3+4+4+5+5+5+6+6+6+7+7+7 = 67/13 = 5.15
If we added an additional data value at 20, the new median would be 5.5. The new mean would be (67+20)/14 = 6.2. The mean changes more than the median.

=> x =12/3 =4
so, original number is 84.
