Answer:
Step-by-step explanation:
Given
<em>Translation: 3 units left and 1 unit right</em>
Required
Determine the new coordinates of B
Write out the coordinates of B
When a function is shifted to the left, we have to subtract the unit from the x value of the function;
<em>Shifting by 3 units left, the new x becomes </em>
<em /><em />
<em /><em />
<em />
When a function is shifted upward, we have to add the unit to the y value of the function;
<em>Shifting by 1 unit up, the new y becomes </em>
Hence, the new coordinates of B is
Answer:

Step-by-step explanation:
For the square:
32•48= 1536 in ^2
For the triangle: 48•12= 576/2= 288 in^2
1536+288= 1824 in^2
Z-score for 30 = (30 - 25) / 5.8 = 0.8621
z-score for 20 = (20 - 25) / 5.8 = -0.8621
:
Note find probabilities from z-tables
:
Probability ( 20 < X < 30 ) = 0.8051 - 0.1949 = 0.6102
