Identify the reflection of the figure with vertices P(−11,−13), Q(−17,19), and R(23,−27) across the x-axis.
Bess [88]

Answer:

P (−11, 13), Q (−17, −19), R (23, 27)

Step-by-step explanation:

we know that

The reflection of a figure across the x-axis has the following rule

(x,y) -----> (x,-y)

so

P(-11,-13) -----> P(-11,13)

Q(-17,19) -----> Q(-17,-19)

R(23,-27) ----> R(23,27)

SOMEBODY PLEASE HELP QUICK!!! WILL GIVE BRAINLIEST
Anna71 [15]

Carlos is correct

Since we don't know the length of sides PR and XZ, the triangles can't be congruent by the SSS theorem or the SAS theorem, and since we don't know the measure of angles Y and Q, the triangles can't be congruent by the ASA theorem, the SAS theorem or the AAS theorem. Therefore, Carlos is correct.

Carlos is correct. Since the angles P and X are not included between PQ and RQ and XY and YZ, the SAS postulate cannot be used, since it states that the angle must be included between the sides. Unlike with ASA, where there is the AAS theorem for non-included sides, there is not SSA theorem for non-included angles, so the triangles cannot be proven to be congruent.

Ymorist [56]

Answer:

116 students

Step-by-step explanation:

The standard deviation for a proportion is:

s=\sqrt{\frac{(1-p)*p}{n}}

For any measured sample proportion x, the z score is given by:

z = \frac{x-p}{s}

The population proportion is 0.53

At the 14th percentile, the corresponding z-score is z =-1.08.

Since 0.48 is at the 14th percentile, the standard deviation is:

-1.08=\frac{0.48-0.53}{s}\\ s=0.46296

Therefore, the sample size 'n' is given by:

0.046296=\sqrt{\frac{(1-0.53)*0.53}{n}}\\n=\frac{0.47*0.53}{0.046296^2}\\n= 116\  students

The sample size must have been of 116 students.

The vertices of Figure ABCD are A(1,1), B(2,3) C(4,3) and D(5,1). If Figure ABCD is reflected over the line y = -1, find the coo
Vlad [161]

Answer:

  • <u><em>(2, - 5)</em></u>

Explanation:

<em>The line y = -1 </em>is horizontal: parallel to the y-axis.

The point<em> B (2,3)</em> is above <em>the line y = - 1 </em>at a distance equal to the y-coordinate of B (y = 3) less - 1:

  • Δy = 3 - ( - 1) = 4

When the <em>point B (2,3) </em>is <em>reflected over the line y = -1</em>, the x-coordinate does not change.  The image will be 4 units down the line y = -1, thus the y-coordinate will be - 1 - 4 = - 5.

Hence,<em> the coordinates of the vertex B'</em> are x = 2, y = - 5: (2, - 5).
