The other answer is wrong. It says 4 round trips so 4x2=8. So 8x47 is your answer

What is the median for the set of data? Ages Stem Leaves

Temka [501]

Answer:

This is a stem leaf data, in which the stem generally stands for the "tens" place value while the leaf stands for the "ones" place value.

Expand the data, and find the median by finding the middle number:

10, 13, 16, 20, 21, 23, 27, 27, 28, 29, 30, 32, 33, 33, 33, 33, 38, 39, 46, 46, 46, 48

There are 22 numbers in all. To find the Median when there is a even amount of numbers, Find the two middle numbers, and find the mean of the two numbers:

(32 + 30)/2 = (62)/2 = 31

31 is your answer.

A rectangle has a length of x and a width of 5x^3+4-x^2. What is the polynomial that models the perimeter of the rectangle

sveticcg [70]

Answer:

$L= x$

And the width for this case is:

$W= 5x^3 +4 -x^2$

And we know that the perimeter is given by:

$P= 2L +2W$

And replacing we got:

$P(x) = 2x +2(5x^3 +4 -x^2)= 2x +10x^3 +8 -2x^2$

And symplifying we got:

$P(x)= 10x^3 -2x^2 +2x+8$

Step-by-step explanation:

For this problem we know that the lenght of the rectangle is given by:

$L= x$

And the width for this case is:

$W= 5x^3 +4 -x^2$

And we know that the perimeter is given by:

$P= 2L +2W$

And replacing we got:

$P(x) = 2x +2(5x^3 +4 -x^2)= 2x +10x^3 +8 -2x^2$

And symplifying we got:

$P(x)= 10x^3 -2x^2 +2x+8$
