2x5= p divided by 3
2x5=10
10÷3=3.33
so it is 3 1/3
Answer:
0.15866.
Step-by-step explanation:
We have been given that on average, electricians earn approximately μ= $54,000 per year in the united states. Assume that the distribution for electricians' yearly earnings is normally distributed and that the standard deviation is σ= $12,000. We are asked to find the probability that the sample mean is greater than $66,000.
First of all, we will find the z-score corresponding to 66,000 using z-score formula.




Now, we need to find the probability that z-score is greater than 1 that is
.
Upon using formula
, we will get:

Upon using normal distribution table, we will get:


Therefore, the probability that the sample mean is greater than $66,000 would be 0.15866 or approximately
.
Answer:
$20.06
Step-by-step explanation:
17 x 0.18 = 3.06 Multiply the cost by the tip percent
17 + 3.06 = $20.06 Add the tip amount to the original cost
Answer:
3m/s
Step-by-step explanation:
delta y = 40m - 10m = 30m
delta x = 20s - 10s = 10s
slope = delta y / deltax = 30m / 10s = 3m/s
