Answer:
If he spins a spinner with 5 equal sections they have equally likely probability of 20%
If he rolls a fair die in the shape of pyramid with 4 sides each side has probability of 25%
If he rolls a fair die in the shape of cube with 6 sides each side has probability of 16.7
Total number of outcomes = 5 * 6 * 4 = 120
Answer:
0.19706
Step-by-step explanation:
-Given the mean salary is $65,000 and the standard deviation is $6,000, the probability of making between $70000 and 80000 can be calculated as:
Hence,the probability that an employee makes between $70,000 and $80,000 is 0.19706
Answer:
7/9 + (-7/9) = 0
Step-by-step explanation:
Definition of additive inverse:
Two numbers are additive inverses if their sum is zero.
For example, 2 and -2 are additive inverses since 2 + (-2) = 0.
Now your problem:
7/9 + (-7/9) =
7/9 and -7/9 are additive inverses.
Therefore, their sum is 0.
7/9 + (-7/9) = 0
