The intersection of A and B' is an empty set because there are no elements that are in both A and B'. The correct answer is (option E) the empty set.
What is a set ?
A set is a collection of distinct objects, called elements or members, that are well-defined and unordered.
We can start by finding the complement of set B, which consists of all the elements in U that are not in B:
B' = {r, t, v, x, z}
Then, A ∩ B' consists of all the elements that are in A and also in B':
A ∩ B' = {u, w, y} ∩ {r, t, v, x, z} = { }
Therefore, The intersection of A and B' is an empty set because there are no elements that are in both A and B', the correct answer is (option E) the empty set.

x = 20
Step-by-step explanation:
Given BD = CD then Δ BCD is isosceles and the 2 base angles are congruent
∠ CBD = ∠ BCD = 40° , then
∠ BDC = 180° - (40 + 40)° = 180° - 80° = 100° ← sum of angles in triangle
Sum the 3 angles of Δ ACD and equate to 180
20 + 100 + x + 40 = 180
160 + x = 180 ( subtract 160 from both sides )
x = 20

What is the perfect square after 144?
Answers
The perfect square after 144 is the number 169 .
The Perfect Square is defined as the number that can be expressed as product of an integer by itself .
For example, 36 is a perfect square because it is product of integer 6 by itself, 6 × 6 = 36 . Whereas , the number 15 is not a perfect square because it cannot be expressed as product of two same integers .
The number 144 is the perfect square of integer 12 ,
so the next integer 13 , the square of 13 is = 13 × 13 = 169 .
Therefore , the next perfect square after 144 is 169 .

Answer:
80% decrease
Step-by-step explanation:
Find out how much percent each candy is worth:
100/15 = 6.67%
Find out how many pieces she gave away:
15 - 3 = 12
Multiply the pieces gave away by the percent per piece:
12 x 6.67 = 80.04
Round to the nearest whole number.
When using a calculator for 100/15 and then multiply by 12 you get exactly 80.

Answers
The corresponding parts in the two triangles are:
- Side LM corresponds to side QR.
- Angle L corresponds to angle R.
The given question asks us to identify the corresponding parts between two triangles, triangle LMN and triangle QRP, after a series of transformations.
To determine the corresponding parts, let's analyze each transformation step by step:
1. Triangle LMN is rotated 180° clockwise about point M. This means that every point in triangle LMN is rotated by 180° in a clockwise direction around point M.
2. After the rotation, triangle LMN is then translated up. This means that every point in triangle LMN is moved vertically upwards by the same distance.
Now, let's consider the corresponding parts between the two triangles:
- Side LM corresponds to side QR. This is because after the rotation and translation, the side LM of triangle LMN aligns with side QR of triangle QRP.
- Angle L corresponds to angle R. This is because after the rotation, angle L of triangle LMN becomes angle R of triangle QRP. The rotation preserves the measure of the angles.

Use appropriate window values to identify the period of each function in radians and in degrees. Then evaluate each function at 90° . y=-3sin x
Answers
The period of the periodic function y = -3sin(x) is 2π/3 radians or 120 degrees. A suitable window for graphing the function is Xmin = 0, Xmax = 4π/3, Ymin = -3, Ymax = 3.
The given function is y = -3sin(x). To identify the period of the function, we need to determine the values of x for which sin(x) repeats itself. Since the sine function has a period of 2π, the period of y = -3sin(x) is:
T = 2π / |(-3)| = 2π / 3
Therefore, the period of the function is 2π/3 radians or 120 degrees.
To evaluate the function at 90 degrees, we need to convert 90 degrees to radians:
90° = π/2 radians
Substituting this value into the function, we get:
y = -3sin(π/2) = -3(1) = -3
Therefore, the value of the function at 90 degrees is -3.
To plot the graph of the function and verify the period, we can use a window of:
Xmin = 0
Xmax = 4π/3
Ymin = -3
Ymax = 3
This window covers one and a third cycles of the function, which is enough to verify the period.

What percentage of canadians live within 100 miles of the u. S. Border?.
Answers
Answer:
90%
Step-by-step explanation:
A grocer has 5 apples and 5 oranges for a window display. The grocer makes a row
of the 10 pieces of fruit by choosing one piece of fruit at random, making it the first
piece in the row, choosing a second piece of fruit at random, making it the second
piece in the row, and so on. What is the probability that the grocer arranges the fruits
in alternating order? (Assume that the apples are not distinguishable and that the
oranges are not distinguishable.)
Answers
The probability that the grocer arranges the fruits in alternating order is 5/16.
What is probability?It is a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.
According to question:There are only two ways that the fruits can be arranged in alternating order: apple-orange-apple-orange-apple-orange-apple-orange or orange-apple-orange-apple-orange-apple-orange-apple.
Let's consider the first case where the first fruit is an apple. The probability of this happening is 1/2 since there are 10 total fruits and 5 of them are apples. Once the first fruit is chosen, there are 4 apples and 5 oranges left. The next fruit must be an orange, which has probability 5/9 of occurring since there are now 9 fruits left and 5 of them are oranges. The third fruit must be an apple, which has probability 4/8 (or 1/2) of occurring since there are 8 fruits left and 4 of them are apples. Continuing in this way, we get the following probability:
(1/2) * (5/9) * (4/8) * (4/7) * (3/6) * (3/5) * (2/4) * (2/3) * (1/2) * 1
The second case where the first fruit is an orange is the same as the first case but with the roles of apples and oranges reversed. So the probability of arranging the fruits in alternating order is:
(1/2) * (4/9) * (5/8) * (3/7) * (4/6) * (2/5) * (3/4) * (1/3) * (2/2) * 1
Simplifying both expressions, we get:
(5!/(4!1!)) * (4!/(2!2!)) * 1/(2^5) + (5!/(4!1!)) * (4!/(2!2!)) * 1/(2^5)
= 10/32 + 10/32
= 5/16
Therefore, the probability that the grocer arranges the fruits in alternating order is 5/16.

for b you simplify both sides of the equation, and then you get -7b - 1 = 5B + 15 then you subtract 5 from both sides which gets you to -12b - 1 = 15 then you divide both sides by negative 12 which would be negative 12 b - -12 = 16-12 which gives you the answer of -4/3.
for x you would subtract 3x from both sides which gets you to 6x - 17 = 7 and then you would add 17 to both sides which would give you 6X = 24 and then you would divide both sides by 6 which would give you x = 4
