On a cube, you have 6 faces, therefore you have 1 chance to get 6 and 5 chances not to get 6.
Therefore, the overall probability not to get 6 is 5/6 = 0.8333
If you roll the cube 18 times, the prediction of unsuccessful rolls will be:
18 × 0.8333 = 15
Therefore, you expect to have 15 unsuccessful rolls over 18 total rolls.

Answer:
Step-by-step explanation:
8×4 = (A×7) - (A×3) = A(7-3) = A×4
A = 8
Answer:
$7,305.50
Step-by-step explanation:
The computation of the FICA tax pay in 2005 is shown below:
Medicare = 1.45% × $119,000 = $1,722.50
And, Social security tax = 6.2% × 90,000 = $5,580
So, the FICA tax in 2005 is
= Medicare tax + Social security tax
= $1,722.50 + $5,580
= $7,305.50
21-6=15
The range of the set is 15
