Answer:

The difference (in km) between what Kayden ran and what Jayden ran is, 7.867 km.

Step-by-step explanation:

The information provided is as follows:

  • Kayden ran 8 km.
  • Cayden ran half of distance Kayden ran.
  • Isaac ran 1/5 of the distance Cayden ran.
  • Jayden ran 1/6 of what Isaac ran.

So, using the given information it can be said that Cayden ran 4 km.

Then the distance Isaac ran is, 4\ \text{km}\times\frac{1}{5}=0.8\ \text{km}.

Then the distance Jayden ran is, 0.8\ \text{km}\times\frac{1}{6}=0.133\ \text{km}

Compute the difference (in km) between what Kayden ran and what Jayden ran as follows:

K-J=8-0.133=7.867

Thus, the difference (in km) between what Kayden ran and what Jayden ran is, 7.867 km.

Answer:

The right answer is:

The poll provides strong evidence that more than 61% of Americans oppose the Tea Party movement this year. Why? The P-value (0.026) is less than the significance level of 5%.

Step-by-step explanation:

At a level of significance of 5%, a P-value of 0.026 (2.6%) means that the difference is significant and the null hypothesis is rejected.

The difference between the proportions is significant, what means that more than 61% of Americans oppose the Tea Party movement this year.

Note: The difference in the sample proportions (3%) is not enough to claim that the difference is significant.

The right answer is:

The poll provides strong evidence that more than 61% of Americans oppose the Tea Party movement this year. Why? The P-value (0.026) is less than the significance level of 5%.

Wilbur sold half of his comic books and then bought fourteen more. he now has 24. how many did he begin with?
rosijanka [135]
First, subtract 24 - 14 to get how many books he had after he sold half of his collection and bought 14 more:

24 - 14 = 10

10 = number of books after he sold half of his collection.

Now, you need to multiply 10 x 2, because you need to find the original number of comic books:

10 x 2 = 20

He originally had 20 comic books.

An equation you could use for this question is:

2(24 - 14) = x. (X = number of comic books)

Hope this helps!!
