Answer:

452.2 cm

Step-by-step explanation:

A = 4πr²

I WILL GIVE BRAINLIEST! ONLY ANSWER IF YOU KNOW ITS CORRECT! (08.04 MC)Mia creates a box plot using 28, 34, 40, 24, 44, 49, and

victus00 [196]

9514 1404 393

Answer:

(d)

Step-by-step explanation:

When the data is put in order, the values are ...

24, 28, 32, 34, 40, 44, 49

The middle value is 34. This is the median, where the line in the middle of the box plot is located. Only one answer choice has this correctly placed.

When the median is removed, the data set is divided into two parts:

24, 28, 38 and 40, 44, 49

The middle value of each of these will be the lower and upper quartiles, the ends of the box in the box plot. Those are 28 and 44.

So, the box plot has whiskers that extend to the extreme data points of 24 and 49, box ends at 28 and 44, and a median line at 34. The last choice matches this description.

PLEASE HELP ME <br>Multiply the monomials: <br><br>a2x5b, −0.6axb2 and 0.6a2b3

Tanzania [10]

Answer:

$-0.36 a^{5}b^{6} x^{6}$

Step-by-step explanation:

Given:

$a^2x^5b,,\ -0.6axb^2,\ and\ 0.6a^2b^3$

Required

Multiply

The above can be written as

$a^2x^5b * -0.6axb^2\ * \ 0.6a^2b^3$

Split the above expression

$a^2*x^5*b * -0.6*a*x*b^2\ * \ 0.6*a^2*b^3$

Collect like terms

$-0.6 * 0.6 * a^2*a*a^2*b *b^2 *b^3*x^5*x$

Apply first law on indices

$-0.36 * a^{2+1+2} *b^{1+2+3} *x^{5+1}$

$-0.36 * a^{5} *b^{6} *x^{6}$

$-0.36 a^{5}b^{6} x^{6}$

Hence, $a^2x^5b * -0.6axb^2\ * \ 0.6a^2b^3$ is equivalent to $-0.36 a^{5}b^{6} x^{6}$
