Hey there! 
Your answer is C. 
If you take the lengths of the legs of the triangle, which are 12 and 4, we can multiply them by the scale factor to see what the legs of our new triangle is.
12 x 1/4 = 3 
4 x 1/4 = 1
So, the legs of our new triangle have lengths of 1 and 3. 
We can see that option C has the correct triangle in red. 
If we're looking at the ratio of rise to run of each triangle, it is 1/3 for both the large triangle and the small triangle. 
The rise for the larger triangle is 4, and the run is 12. That is 4/12, which can be simplified to 1/3. 
The rise for the smaller triangle is 1, and the run is 3. That is 1/3, which is all the way simplified already. 
These triangles are similar because the first one was dilated to get the second one, which explains why the ratios are the same. 
Hope this helps!   
 
        
             
        
        
        
Notice that the reflection is over a line of the form x=constant; in this case, the y-coordinate of the reflected point stays the same while the x-coordinate changes as expressed by the transformation below

Hence, in our case

Transform points N, M, and O accordingly,

<h2>Therefore, the answer is the first option (top to bottom)</h2>
 
        
             
        
        
        
Answer:
see explanation
Step-by-step explanation:
2 chords intersecting inside a circle , then the product of the parts of one chord is equal to the product of the parts of the other chord.
6
BE × ED = AE × CE , that is
10 × 3x = 12(2x + 1) ← distribute parenthesis by 12
30x = 24x + 12 ( subtract 24x from both sides )
6x = 12 ( divide both sides by 6 )
x = 2
then
ED = 3X = 3(2) = 6
7
RJ × JP = SJ × JQ , that is
6 × 3x = 4(4x + 1) ← distribute parenthesis by 4
18x = 16x + 4 ( subtract 16x from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
then
RP = RJ + JP = 6 + 3x = 6 + 3(2) = 6 + 6 = 12
 
        
             
        
        
        
Answer: a)  Unimodal and symmetric
b) 0.26
c) 0.038
Step-by-step explanation:
Given: Sample size of investors (n)= 131
True proportion of smartphone users(p)  =26% 
a) Since sampling distribution for the sample proportion is approximately normal when n is larger.
Normal distribution is Unimodal and symmetric.
So correct option : Unimodal and symmetric
b)  mean of this sampling distribution = p = 0.26 
c)  standard deviation of the samplingdistribution =
