Answer:

There are 24 different orders in which they can give their speeches.

Step-by-step explanation:

Consider the provided information.

Four students have to give a speech in the class room.

Let their names are A, B, C and D.

For the first speech, we have 4 choices of the students. i.e. A, B, C, and D.

Suppose that "A" gives the first speech.

Now, for the second speech, we have 3 choices of the students. i.e. B, C, and D.

Suppose that "B" gives the second speech.

For the third speech, we have 2 choices of the students. i.e. C and D.

Suppose that "C" gives the third speech.

Now, for the fourth speech, we have only one choice. i.e. D.

If we observed the pattern we can find that, there were 4 choices at first, then there were 3 choices, then 2 and lastly 1.

Thus the total number of different orders are 4×3×2×1 = 24.

Hence, there are 24 different orders in which they can give their speeches.

x varies jointly with the square of y and z. when y=6 and z=5, x=100. Then, what is x when y=8 and z=2?
djyliett [7]
X = k*y^2 * z
100 = 6^2*5*k,
k=0.555
x=0.555zy^2

x=o.555(8^2)(2)=71.1112.

On August 7, 2007 Barry Bonds hit his 756th home run, breaking the all-time career home run record, formerly held by Hank Aaron.
svp [43]

From the stemplot, it can be taken that:

Both were very consistent home run hitters, due to the great amount of seasons with at least 20 home runs. Bonds had the biggest outlier, with a season of 73 home runs, while Aaron distribution was less spread.

-------------------------------

  • From the stemplot, it can be taken that Bonds had the biggest outlier, which was the season with 73 home runs.
  • His season with the lowest amount of home runs was also less than Aaron, as he had a 5 home run season while Aaron lowest amount was 10.
  • They both had a lot of seasons with at least 20 home runs, so both very consistent.

Thus, we can take that:

Both were very consistent home run hitters, due to the great amount of seasons with at least 20 home runs. Bonds had the biggest outlier, with a season of 73 home runs, while Aaron distribution was less spread.
