For which value of x is ABCD a kite?
Answer:
83
Step-by-step explanation:
x+7+90
x=83
The value of x is ABCD a kite would be 83 units. The correct answer would be an option (A).
What is the rhombus?A rhombus is a quadrilateral having four equal-length sides that are parallel to one another.
As we know Rhombuses' opposing interior angles are congruent, and their diagonals always bisect each other at right angles.
As per the given figure, this means (x + 7) = 90 degrees
⇒ (x + 7) = 90
⇒ x = 90 - 7
Apply the subtraction operation, and we get
⇒ x = 83
Thus, the value of x is ABCD a kite would be 83 units.

A company makes a bracelet that is designed to repel mosquitoes so people don't have to wear bug spray. Researchers at the company are designing an experiment where volunteers will be assigned either the bracelet or bug spray to use at their homes. The researchers want to use a randomized block design. How should the researchers form the blocks
Answer: volunteer within each block should live in similar environments to each other when it comes to mosquitos
Step-by-step explanation:
The researchers using a randomized block design should form the blocks by making the;
Volunteers within each block should live in similar environments to each other when it comes to mosquitos.
A randomized block design is simply a type of experiment where the experimental units are put in groups known as blocks.
Now, we are told that;
- A company is designing an experiment where volunteers will be assigned either the bracelet or bug spray to use at their homes.
- They are doing the experiment because they want to make a bracelet that can repel mosquitoes so people don't have to wear bug spray anymore.
Now, this implies that the environment they find themselves has a big impact on the outcome of the experiment. This is because different environments could have different exposure conditions to mosquitoes and as a result it will be better for them to be within the same environment for better experimental results.

The transformation was a 270° rotation about the origin.
The transformation was a 360° rotation about the origin.ear pair
Answer:
It's a 180 rotation
Step-by-step explanation:
The first set of chords are in the first quadrant while the second set of chords are in the third quadrant. If you draw the first triangle on a second sheet of paper in the same place a the first triangle and hold the paper so that the triangle you drew of the first triangle is directly on top of the first triangle and then hold the paper at the point (0,0) and move the paper 180 degrees, it doesn't matter which direction cause it's 180 degrees, the points of the triangle will have ended up in the third quadrant. So it's 180 degree rotation
In a class of 25 students, 15 are female and 16 have an A in the class. There are 12 students who are female and have an A in the class. What is the probability that a student has an A given that the student is female?
Answer:12/16
Step-by-step explanation:
The probability that a female student has an A in the class is 0.8 or 80%.
How to calculate the probability?To calculate the probability that a student has an A given that the student is female, we can use the formula for conditional probability:
[tex]P(A|F) = \dfrac{P(A U F)} { P(F)}[/tex]
where P(A|F) is the probability of having an A given that the student is female, P(A and F) is the probability of being both female and having an A, and P(F) is the probability of being female.
We are given that there are 25 students in the class, 15 of whom are female and 16 of whom have an A. We are also given that there are 12 students who are both female and have an A.
Using this information, we can calculate the probabilities as follows:
P(F) = 15/25 = 0.6
P(A and F) = 12/25
The probability that a student has an A given that the student is female is:
[tex]P(A|F) = \dfrac{P(A U F)} {P(F)} \\P(A|F) = \dfrac{\dfrac{12}{25} }{ (\dfrac{15}{25})} \\P(A|F)= 0.8[/tex]
The probability is 80%.

The area of a triangular wedge is 90 square inches. The height is 18 inches.
What is the base2
Hello!
[tex]\large\boxed{b = 10in}[/tex]
Formula for the area of a triangle:
A = 1/2(bh)
We are given the height and area, so we can plug those into the formula to solve for b:
90 = 1/2(18b)
Multiply both sides by 2:
180 = 18b
Divide both sides by 18:
b = 10 inches.
Answer:
10inches is equal to the base
Step-by-step explanation:
formula for finding the area of a triangle is
½bh which is half times base times height
-base is unknown, height is 18 and area is 90.
-½x*18=90
½of 18 is 9
1x*9=90
9*x=9x
therefore:9x=90
we devide both sides by the co-efficient of x which is 9
9 dividing 90 is 10.
therefore x is equal 10

[tex]z^{4} = \cos \frac{8\pi}{3}+i\,\sin \frac{8\pi}{3}[/tex]
Step-by-step explanation:
We can determine the power of a complex number by the De Moivre's Theorem, which states that for all [tex]z = r\cdot (\cos \theta + i\,\sin\theta)[/tex], where [tex]a, b \in \mathbb{R}[/tex], the power of the complex number is:
[tex]z^{n} = r^{n}\cdot (\cos n\theta + i\,\sin n\theta)[/tex] (1)
Where:
[tex]r[/tex] - Magnitude of the complex number, dimensionless.
[tex]\theta[/tex] - Direction of the complex number.
If we know that [tex]r = 1[/tex], [tex]n = 4[/tex] and [tex]\theta = \frac{2\pi}{3}[/tex], then the fourth power of the complex number is:
[tex]z^{4} = 1^{4}\cdot \left[\cos\left(\frac{8\pi}{3} \right)+i\,\sin\left(\frac{8\pi}{3}\right)\right][/tex]
[tex]z^{4} = \cos \frac{8\pi}{3}+i\,\sin \frac{8\pi}{3}[/tex]

Multiply both sides by 2
2(21 + 2x) = 2x + 24
42 + 4x = 2x + 24

Know more about line:
A line has length but not width. A line is a type of geometric shape that can move in either direction. A line consists of an infinite number of points. It is infinite and has no end on either side. The row is one-dimensional.
In geometry, the term line or straight line was introduced by ancient mathematicians to denote straight objects of negligible width and depth. It is often described as two points.
A line in a plane is often defined as a set of points whose coordinates correspond to a given linear equation in the sense of analytic geometry, while a line can be an independent object distinct from the points on it. drop geometry.
Here given two points are (−3,−4) and (−7,16).
According to rule,slope of the line that goes through points (−3,−4) and (−7,16)
[tex] = \frac{16 - ( - 4)}{ - 7 - ( - 3)} \\ = \frac{16 + 4}{ - 7 + 3} \\ = \frac{20}{ - 4} \\ = - 5[/tex]
