Answer:
-4,3.5
Step-by-step explanation:
1st one
x-2x-20 = 12
-x = 32
x=-4
2nd one
-15=15q-50 - 5q
35= 10q
q = 3.5
D divide by 1000… you are shifting the decimal 3 places (there are 3 zeros in 1000) you are dividing because the number is getting smaller.
Answer:
the independent variable is amount being paid per hour, as the final outcomes relys on that answer. the dependent variable is the hours worked, as thats the variable that can be changed.
Answer:
you're question is complicated
Step-by-step explanation:
Answer:
The probability that the mean delivery time from the sample of 25 orders xˉ is farther than 2 minutes from the population mean cannot be calculated.
Step-by-step explanation:
As given in the question statement, the distribution of delivery times is strongly skewed to the right. The population distribution is skewed to right. Too much skewed distribution can cause the statistical model to work ineffectively and affects its performance. The probability can also not be calculated because the sample size is too small. Small sample size affects the results and makes them less reliable because it results in a higher variability and likelihood of skewing the results.
