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.
To determine the total class the whole class spent, you just have to simply add the individual costs of the three books. Using parenthesis, the solution can be written in the following two ways:
($15 + $9) + $12 = $36
$15 + ($9 + $12) = $36
No matter where you put the parenthesis, the final answer doesn't change. This is because of the Commutative Property of Addition. The order does not matter.
Answer:
y-7 = -2 (x-4)
Step-by-step explanation:
Point Slope Form:
, where m is the slope of the line
They tell you that the line has a slope of -2, so that will go in the first yellow box. They also tell you that the line passes through the point (4, 7), so those are the values for x1 and y1. They've already filled in y1 with 7, so x1 (which is 4) will go in the second yellow box
y-7 = -2 (x-4)
1)a) 1:4
b) 2:1
c) 1:4
d) 1:70
e) 7:18
f) 100:3
I think they're all right :)
