A sofa is on sale for 27% off. The sale price is $657.

blondinia [14]

Answer:

If $657 is 27% off, then $657 = 100-27% or 73%.

So you want to know what's 100%. So you use a ratio. 100/73 * $657. Which equals $900.

If h(x) = 3x − 1 and j(x) = −2x, solve h[j(2)] and select the correct answer below.

mamaluj [8]

Answer:

- 13

Step-by-step explanation:

To evaluate h(j(2)) substitute x = 2 into j(x) then substitute the value obtained into h(x)

j(2) = - 2 × 2 = - 4, then

h(- 4) = (3 × - 4) - 1 = - 12 - 1 = - 13

Hence h(j(2)) = - 13

An urn contains two blue balls (denoted B1 and B2) and three white balls (denoted W1, W2, and W3). One ball is drawn from the ur

tatuchka [14]

Answer:

(a)10 Outcomes

(b) $\dfrac{2}{5}$

Step-by-step explanation:

An urn contains two blue balls (denoted $B_1 \:and\: B_2$ ) and three white balls (denoted $W_1, W_2 \:and\: W_3$ ).

In the selection, a ball is picked and replaced.

The possible outcomes of the experiment are:

$B_1B_1,B_1B_2,B_1W_1,B_1W_2,B_1W_3\\B_2B_1,B_2B_2,B_2W_1,B_2W_2,B_2W_3\\W_1B_1,W_1B_2,W_1W_1,W_1W_2,W_1W_3\\W_2B_1,W_2B_2,W_2W_1,W_2W_2,W_2W_3\\W_3B_1,W_3B_2,W_3W_1,W_3W_2,W_3W_3$

(a)If the first ball drawn is blue. the outcomes are:

$B_1B_1,B_1B_2,B_1W_1,B_1W_2,B_1W_3\\B_2B_1,B_2B_2,B_2W_1,B_2W_2,B_2W_3$

There are 10 outcomes if the first ball drawn is blue.

Probability that the first ball drawn is blue

$=\dfrac{10}{25}\\ =\dfrac{2}{5}$
