Answer:

$10 \frac{9}{25}$

Step-by-step explanation:

$\bigg( \frac{3}{5} \bigg)^{2} + 4 \times 3 - 2 \\ \\ = \frac{9}{25} + 12 - 2 \\ \\ = \frac{9}{25} + 10 \\ \\ = \frac{9 + 10 \times 25}{25} \\ \\ = \frac{9 + 250}{25} \\ \\ = \frac{259}{25} \\ \\ = 10 \frac{9}{25}$

Which could be the missing data item for the given set of data if the median of the complete data set is 50?

gogolik [260]

Answer:

Find the median of this data

21+23+60+60+50+54+54+59+26+15+43+15=480/ 12 = 40

Now the median should be 50 so take 50 - 40 = 10

Mario simplified the expression (4 z Superscript 8 Baseline) Superscript negative 3 as shown. (4 z Superscript 8 Baseline) Super

GREYUIT [131]

Answer:

Step-by-step explanation:

Given the expression $(4z^8)^{-3}$ , to evaluate this, we will use one of the law of indices as shown;

$(a^m)^n = a^{mn}$

$4^{-3} * z^{8*-3}$

$= \frac{1}{4^3} * z^{-24}\\ \\= \frac{1}{64} * \frac{1}{z^{24}}\\ \\= \frac{1}{64z^{24}}$

Mario's error was that she did not raise the value of 4 to the power of -3. She only raised z^8 to the power of -3 when it is supposed to affect both 4 and z^8
