Answer:
Hey there!
The range is the possible y values, so the range of this graph would be all real numbers less than or equal to -6.
Let me know if this helps :)
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.
answer
0.54
explanation
since student A and student B are independent of each other, we multiply their individual probabilities to get the probability of both solving the problem
A * B
= 0.9 * 0.6
= 0.54
there is a 0.54 probability that both will solve the problem
Answer: B
Step-by-step explanation:
When B is simplified, it becomes x^2-3x-10. This is a polynomial because it has more than two terms(3).
Hope it helps <3
EXPLANATION:
10 - ( 3 + 2*2 ) + 4
=> 10 - ( 3 + 4 ) + 4
=> 10 - 7 + 4
=> 3 + 4
=> 7
ANSWER: A. 7
Hope it helps u!
