Answer:
a. 99.7%
b. 68%
Step-by-step explanation:
The empirical rule for approximately symmetrical and bell-shaped distributions states that:
68% of the data are among the values (means - sd) and (means + sd)
95% of the data are among the values (means - 2*sd) and (means + 2*sd)
99.7% of the data are among the values (means - 3*sd) and (means + 3*sd). So that,
68% of the data are among the values (180 - 8) = 172 and (180 + 8) = 188
95% of the data are among the values (180 - 16) = 164 and (180 + 16) = 196
99.7% of the data are among the values (180 - 24) = 156 and (180 + 24) = 204
Answer:
c
Step-by-step explanation:
Answer:
108
Step-by-step explanation:
Square of 9 = 9×9 = 81
Cube of 3 = 3×3×3 = 27
So sum of square of 9 & cube of 3 = 81+27 = 108
I'm guessing that by "counting numbers" you're refering to "integers."
Why not actually write out the numbers that qualify, and then count them?
{2, 3, 5, 6} is a set of four numbers, all of which are fewer than 3 units away from the (central) number 4. Some people would include 4 itself in this set.
