Triangles X Y Z and X prime Y prime Z prime are shown.
ΔXYZ was reflected over a vertical line, then dilated by a scale factor of One-half, resulting in ΔX'Y'Z'. Which must be true of the two triangles? Select three options.
△XYZ ~ △X'Y'Z'
AngleXZY ≅ AngleY'Z'X'
YX ≅ Y'X'
XZ = 2X'Z'
mAngleYXZ = 2mAngleY'X'Z'
Answer:
1,2,4
Step-by-step explanation:
I just took the test and got it right and its the only logical answer.
If ΔXYZ, after reflection and dilation by a scale factor of 1/2, ΔX'Y'Z' is created, the following would be true:
1. △XYZ ~ △X'Y'Z'
2. AngleXZY ≅ AngleY'Z'X'
4. XZ = 2X'Z'
Dilation of ShapesWhen a shape is dilated, the new image formed is similar to the original shape.Similar shapes have proportional side but congruent corresponding angles.Thus, if ΔXYZ, after reflection and dilation by a scale factor of 1/2, ΔX'Y'Z' is created, the following would be true:
1. △XYZ ~ △X'Y'Z'
2. AngleXZY ≅ AngleY'Z'X'
4. XZ = 2X'Z'

An article claimed that only 38\88, percent of hotel visitors used the alarm clock provided. A hotel manager wanted to see whether that proportion applied to the hotel where she worked, so she took a random sample of 700700700 of the approximately 10{,}00010,00010, comma, 000 visitors to the hotel one month and checked whether they used their room alarm clock. Of the sampled visitors, only 35\55, percent used the alarm clock. Assuming that the article's 38\88, percent claim is also the true proportion for visitors to the hotel, what is the approximate probability that less than 35\55, percent of the sample used the alarm clock
Answer: P(p<0.35) = 0.05
Step-by-step explanation:
Khan told me
The approximate probability that less than 355 of the same used the alarm clock will be equal to 0.0485.
What is Probability?Probability is calculated as the proportion of favorable events to all potential scenarios of an event. The proportion of positive results, or x, for an experiment with 'n' outcomes can be expressed.
As per the given information given in the question,
P = 0.38
Q = 1 - P = 1 - 0.38 = 0.62
n = 700 and sample proportion, p = 0.35
Use the formula given below,
z = (p - P)/√(PQ/n)
z = (0.35 - 0.38)/√(0.38 × 0.62)/700
z = -0.03/0.018
z = -1.666
Now,
For P(X < 35%) = P(Z < -1.66)
= P(-∞ < Z < 0) - P(-1.66 < Z < 0)
= 0.5 - 0.4515 = 0.0485

g(x)=1/6(8)^x-5. x=9
Answer:
[tex]g(9) = \frac{2048}{3}[/tex]
Step-by-step explanation:
Given

[tex]x = 9[/tex]
Required
Solve
Substitute 9 for x in [tex]g(x) = \frac{1}{6}(8)^{x-5}[/tex]
[tex]g(9) = \frac{1}{6}(8)^{9-5}[/tex]
[tex]g(9) = \frac{1}{6}(8)^{4}[/tex]

PLEASE HELP MEWhich equation can represent the graph
A. Y=-x^2-4
B. Y= -x^2+4
C. Y=x^2+4
D.y=x^2-4
Answer:
y = - x^2 + 4
which agrees with answer B
Step-by-step explanation:
Notice the graph is that of a quadratic function centered on the y-axis, with negative leading coefficient (branches of the parabola pointing down), and with vertex on the y-axis at the point (0, 4).
Therefore its equation is best represented by:
y = - x^2 + 4
which also crosses the x axis at the points x = -2 and x= 2, in agreement with the graph.
Answer:
B. y = - x²+4

The width of a rectangle a is 12 cm less than the length. The perimeter is 156 cm. Which
equation represents how to find the length and the width?
Answer:
Length is 45cm and Breadth is 33cm
Step-by-step explanation:
Perimeter = 156cm
Let the length be x
Breadth = x-12
Perimter = 2(l+b)
156 = 2(x-12+x)
156 = 2(2x-12)
156 = 4x-24
156+25 = 4x
180 = 4x
180÷4 = x
45 = x
Therefore, length is x = 45cm and breadth is x-12 = 45-12 = 33cm
OUR EQUATIONS
LENGTH = x
BREADTH = x-12

Answer:
112 ft.
Step-by-step explanation:
This shape is a trapezoid. To find the area of a trapezoid, use the formula: [tex]\frac{b_{1} + b_{2} }{2} h[/tex]. First find base one. The shape in the middle is a square, so the top side of the trapezoid will be worth 8 ft as well. Now add the two bases 8 + 20 to get 28 and then divide by 2 to get 14. Now multiply 14 by the height (8). 14 x 8 is 112 ft.

Answer:
Yes, they are similar.
[tex]AB\approx 127.3947[/tex]
Step-by-step explanation:
Part 1)
Yes.
First, ∠D and ∠B are both right angles, so they are congruent.
Next, ∠DCE and ∠BCA are vertical angles. So, their measures are congruent.
Then by Angle-Angle Similarity, we acquire:
[tex]\Delta EDC\sim \Delta ABC[/tex]
Part 2)
The corresponding sides of similar triangles are proportional.
Therefore:
[tex]\displaystyle \frac{DE}{DC}=\frac{AB}{BC}[/tex]
By substitution:
[tex]\displaystyle \frac{103}{76}=\frac{AB}{94}[/tex]
Cross-multiply:
[tex]76AB=9682[/tex]
So:
[tex]AB=9682/76\approx127.3947[/tex]
