Answer:
1080
Step-by-step explanation:
540x2/ or 540 + 540
Answer: Because we are finding the probability of selecting a number less than three, you are left with two options. The answer would be either one, or two.
If you were to also use three it wouldn´t be correct because three is equivalent to three.
There are thirty-nine palindromic numbers between 10 and 400.
Listed, they are: 11, 22, 33, 44, 55, 66, 77, 88, 99, 101, 111, 121, 131, 141, 151, 161, 171, 181, 191, 202, 212, 222, 232, 242, 252, 262, 272, 282, 292, 303, 313, 323, 333, 343, 353, 363, 373, 383, and 393.
x = 9
Number of observations = 6
Sum of observations = 54
Number of observations, n = 6
Mean = ΣX / n
(6 + 8 + x + 2 + 10 + 2x - 1 + 2) / 6 = 9
(27 + 3x) / 6 = 9
27 + 3x = 6 * 9
27 + 3x = 54
3x = 54 - 27
3x = 27
x = 27 / 3
