Answer:

$x=-\frac{1}{2}$ and $x=-2$

Step-by-step explanation:

$f(x)=\frac{2x^2+5x+2}{x^2-4x+3}$

$0=\frac{2x^2+5x+2}{x^2-4x+3}$

$0=\frac{(2x+1)(x+2)}{(x-1)(x-3)}$

$0=(2x+1)(x+2)$

$2x+1=0$ and $x+2=0$

$x=-\frac{1}{2}$ and $x=-2$

The chart below shows conversion between gallons and fluid ounces.

Ainat [17]

<h3>Answer: 768</h3>

======================================================

Explanation:

To go from gallons to fluid ounces (abbreviation fl oz), we multiply by 128

For example, 2 gallons becomes 2*128 = 256 fl oz as shown in the table.

Another example: 3 gallons = 3*128 = 384 fl oz.

Therefore, 6 gallons would be 6*128 = <u>768</u> fl oz.

To go in reverse, from fl oz to gallons, we divide by 128.

An investment advisor believes that there is a 60% chance of making money by investing in a specific stock. If the stock makes m

inessss [21]

Answer:

$\mathbf{ 0.6 \times 0.5 = 0.3 }$

Step-by-step explanation:

Let M denote the event that the stock makes money and D denote the event that the stock pays dividends.

It is given that $P(M) = 0.6$

Observe that the two events M and D are not independent because if the stock doesn't make money then it will not pay dividends. Therefore the event $D | M^{c}$ (D given M does not occur) is a null event, i.e

$P(D|M^{c}) = 0$

It is also given that,

$P(D|M) = 0.5$

Recall that : $P(D|M) = \frac{P(D \cap M)}{P(M)}$

Here, we are required to find $P(D \cap M)$

$P(D \cap M) =P(D|M) \times P(M)= 0.5 \times 0.6 = 0.3$

Sarah's salary =₹ 30000

one-tenth of her salary to an orphanage= 1/10*₹ 30000= ₹ 3000
one-third of her salary is spent on food= 1/3*₹ 30000= ₹ 10000
one-fourth of salary on rent and electricity =1/4*₹ 30000= ₹ 7500
