Standard form of a complex number is :
z = a + b i
$\frac{7}{4 - 14 i} * \frac{4+14i}{4+14i}= \\ \frac{28+98i}{16-14i^{2} }= \\ \frac{28+98i}{16+98}= \frac{28+98i}{212}$ = 7/53 + 49/106 i

The probability of randomly drawing a red card from a bag that contains red, blue, and green cards is 3/10. What is the probabil

Katarina [22]

If the probability of drawing a red card is 3/10, then if we take this fom a whole, 10/10, we can find the probability of not choosing a red card.
10/10-3/10=7/10

The probability of not drawing a red card is 7/10 or 70%.

Put 50%, 2/25, 5, and 0.31 in order from greatest to least

storchak [24]

Answer:

$5,50\%,0.31,\frac{2}{25}$

Step-by-step explanation:

we have

50%, 2/25, 5, and 0.31

1) 50%

we know that

$50\%=\frac{50}{100}$

2) 2/25

Multiply by 4/4

$\frac{4}{4}(\frac{2}{25})=\frac{8}{100}$

3) 5

Multiply by 100/100

$\frac{100}{100}(5)=\frac{500}{100}$

4) 0.31

Multiply by 100/100

$\frac{100}{100}(0.31)=\frac{31}{100}$

Now all numbers have the same denominator

$\frac{500}{100}> \frac{50}{100}>\frac{31}{100}>\frac{8}{100}$

therefore

$5 > 50\%>0.31>\frac{2}{25}$

$5,50\%,0.31,\frac{2}{25}$
