Answer:
Given the 2 values, height and the base, of these 2 triangles, we can assume that they are similar (meaning they share the same angles) as we have no other information to determine the height of the tree.
Therefore, if these triangles are similar, their corresponding sides are proportional. In other words, PZ/RT = QZ/ST or RT/PZ=ST/QZ
Hence, if we find the ratio of this, we can use it to find the side <em>h</em>
<em>QZ/ST=PZ/RT</em>
<em>48/12=PZ/4</em>
<em>PZ/4=48/12</em>
<em>(PZ/4)3=48/12</em>
<em>PZ(3)/12=48/12</em>
<em>48/3=16</em>
16=PZ.
3Step-by-step explanation:
The system of equations is 5x - y - 5 = -7, -6x + 6y + 3z = 8 and -6x - 8y - 2z = 2
<h3>How to determine the system of equations?</h3>
The matrix is given as:
Next, we multiply the matrices
By comparing the position of the cells, we have
5x - y - 5 = -7
-6x + 6y + 3z = 8
-6x - 8y - 2z = 2

<h3>
Answer: 0.235</h3>
======================================================
Explanation:
9 yellow
9 red
9+9 = 18 total
If you select a marble at random, the chances of it being yellow are 9/18.
If you selected another marble at random, without replacing the first marble, then 8/17 is the probability of getting another yellow marble. I subtracted 1 from the numerator and denominator of 9/18 to go to 8/17.
We multiply the two results
(9/18)*(8/17) = 0.235 approximately
There's roughly a 23.5% chance of getting two yellow in a row, where we don't replace the first marble selected.
Answer: you got it right, it is the one that is blue highlighted.
