Answer:

The P-Value is 0.009999

Step-by-step explanation:

we have 5 categories

df=5-1=4

         

With alpha = 1%, the critical Chi-square value is 13.277

The P-value is define as the shows the degree of inconsistency of our data set with hypothesis.

using a significant  level of 0.01,

The P-Value is 0.009999. The result is significant at p <0.01

Select the correct answer.<br> What is the domain of the function shown on the graph?
maw [93]

Answer:

B. negative infinity < x < positive infinity

Step-by-step explanation:

When a question asks for the domain of a function, it is asking for all possible x-values, so we can rule out choice A since there are clearly x-values greater than 1. This graph shows arrows pointing left and downward, indicating that the graph continues past what we can see. This tells us that even though the x-values look like they end at -10 and 2, they continue further, so we can also rule out option C and option D. After these eliminations, we are left with choice B, which is a way of writing "All real numbers," and is the domain for <u>all</u> exponential functions, including this one.

lmk if im incorrect about anything, hope this helps :)

Solutions to the question please. The answer is 3.6km
Afina-wow [57]

Let the Distance between A and B be : C km

Given : The Man Travels from A to B at a Speed 4 km/h

⇒ The Man Travels 4 km in One Hour during his Journey from A to B

⇒ The\;Man\;Travels\;One\;km\;in\;\frac{1}{4}\;Hour\;during\;his\;Journey\;from\;A\;to\;B

⇒ The\;Man\;Travels\;C\;km\;in\;\frac{C}{4}\;Hour\;during\;his\;Journey\;from\;A\;to\;B

Given : The Man Travels from B to A at a Speed 6 km/h

⇒ The Man Travels 6 km in One Hour during his Journey from B to A

⇒ The\;Man\;Travels\;One\;km\;in\;\frac{1}{6}\;Hour\;during\;his\;Journey\;from\;B\;to\;A

⇒ The\;Man\;Travels\;C\;km\;in\;\frac{C}{6}\;Hour\;during\;his\;Journey\;from\;B\;to\;A

⇒ The\;Total\;Time\;Taken\;by\;the\;Man = \frac{C}{4} + \frac{C}{6} = \frac{3C + 2C}{12} = \frac{5C}{12}\;Hour

We know that One Hour contains 60 Minutes

⇒ The Total Time taken by Man =  \frac{5C}{12}\times60\;Min = 25C\;Min

Given Total Time Taken by Man is 45 Minutes

⇒ 25C = 45

⇒ C = \frac{45}{25} = 1.8\;km

But the Total Distance Traveled by the Man is 2C

⇒ 2C = 2 × 1.8 = 3.6 km

⇒ The Total Distance Traveled by the Man is 3.6 km
