A bag contains 14 gray 7 black and 10 white marbles. A marble is drawn at random what is the thecorical probability as a decimal
marta [7]
<h3>Answer:</h3>

<em>The theoretical probability to draw a black marble is </em><u><em>0.23</em></u><em>. </em>

Step-by-step explanation:

First add up the total amount of marbles in the bag.

14 gray marbles + 7 black marbles + 10 white marbles = 31 total marbles.

Since we need the odds of a black marble being drawn, divide 7 (the amount of black marbles) by 31 (the amount of total marbles).

7/31 ---> 0.22580645161   <u><em>(it is easiest to use a calculator on this step)</em></u><em> </em>

Lastly, round the decimal to the nearest hundredth.

0.22580645161 ---> <em>0.23</em>

<em>0.23</em> would be the odds of drawing a black marble.

A bank loaned out $18,000, part of it at the rate of 6% per year and the rest at 16% per
ivann1987 [24]

Answer:

$6500

Step-by-step explanation

x = amount ($) loaned at 6%

then

18000-x = amount ($) loaned at 14%

.06x + .14(18000-x) = 2000

.06x + 2520-.14x = 2000

2520-.08x = 2000

-.08x = -520

x = $6,500
