Lena is converting 2/25 to a percent. What should she multiply the numerator and denominator of the fraction by to find the perc

NNADVOKAT [17]

A percent is a number out of 100, so you'd want to multiply the denominator to get 100. In this case, 25 would have to be multiplied by 4 to get 100. To keep the fractions equal to each other, you have to multiply the numerator by the same thing. 2*4=8. Therefore, your fraction would be 8/100 or 8%

Katarina [22]

Explanation

Part A

We can use the formula below to find the mean.

$\text{Mean}=\sum ^{}_{}(\frac{fx}{f})$

We will then have;

$\begin{gathered} \text{Mean = }\frac{5\times3+4\times1+5\times1+6\times2+7\times2+8\times4+9\times3+10\times1}{19}=\frac{15+4+5+12+14+32+27+10}{19} \\ =\frac{119}{19}=6.2632 \end{gathered}$

Mean = 6.2632

Part B

Since the data set is odd.

$\begin{gathered} \text{Median}=\frac{(n+1)}{2}^{th}\text{observation} \\ =\text{Value of }\frac{\text{(19+1)}}{2}^{th}\text{observation} \\ =\text{value of 10th observation} \end{gathered}$

Answer: From the column of cumulative frequency cf, the median is 7

Hi Veracity,

Answer:

(2 + i) = 2

Step-by-step explanation:

Multiply the denominator and numerator by the conjugate,

= $\frac{(8 - i)(3 + 2i)}{13}$

Combine Like Terms,

= $\frac{26 + 13i}{13}$

Simplify,

= 2 + i

Hope This Helps :)
