using the following table, what is the percent of the relative frequency of a blue car being observed?
An observation of a blue automobile occurs at 20.8% of the relative frequency.
What is Relative frequency?The ratio (fraction or proportion) of the number of times a data value appears in the set of all outcomes to the total number of outcomes is known as the relative frequency.
Divide each frequency by the overall sample size, in this example 20 students, to determine the relative frequencies.
Example: Out of a total of 12 games played, your team has won 9 of them, making its winning percentage 9 percent. 9/12, or 75%, is the relative frequency of winning.
So, we have:
RF(A) = f(A) / ∑f
Where f(A) is the frequency of event A and ∑f is the total frequency.
(Refer to the table attached below)
Total car = 251 + 198 + 195 + 293 = 937
The relative frequency of blue cars is as follows:
RF(blue) = 195 / 937 = 0.208 = 20.8%
Therefore, an observation of a blue automobile occurs at 20.8% of the relative frequency.

What is mean by Angle?An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.
Given that;
Figure is shown in image.
Now, By definition of vertically opposite angle,
⇒ (y + 23)° = 63°
Solve for y;
⇒ y + 23 = 63
Subtract 23 both side,
⇒ y + 23 - 23 = 63 - 23
⇒ y = 40
And, By definition of supplementary angles, we get;
⇒ (2x - 17)° + 63° = 180°
Solve for x;
⇒ 2x - 17 + 63 = 180
⇒ 2x + 46 = 180
⇒ 2x + 46 - 46 = 180 - 46
⇒ 2x = 134
⇒ x = 134/2
⇒ x = 67
Thus, The value of variables x and y are, x = 67 and y = 40.

Answer:
Method 1: Calculate 40% discount on original price, then subtract discount from original price.
Amount of discount = 40% of $30
= 0.40 × $30
= $12
New price = $30 - $12 = $18
Method 2:
New price = (100% - discount percentage) of original price
= 60% of original price
= 0.60 × $30

The statements are true, as they can be demonstrated using the definitions of continuity, limit, and derivative.
Let f and g be two functions with domain over the real numbers and let a be a real number.
The following statement is true: If f(x) is continuous at a, then f(a) is differentiable at a. This can be demonstrated by the definition of continuity at a point. If f is continuous at a, then for any ε > 0 there exists a δ > 0 such that |f(x) - f(a)| < ε if 0 < |x-a| < δ. This implies that the function is differentiable at a, since the limit of the difference quotient, lim (f(x) - f(a))/(x-a) exists as x approaches a.
The following statement is true: If lim f(z) = 0 and lim g(a) = 0, then lim (f(x)/g(x)) = 0. This can be demonstrated by the definition of a limit. Since the limit of f(x) as x approaches a is 0, then for any ε > 0 there exists a δ > 0 such that |f(x)| < ε if 0 < |x-a| < δ. Similarly, since the limit of g(x) as x approaches a is 0, then for any ε > 0 there exists a δ > 0 such that |g(x)| < ε if 0 < |x-a| < δ. Thus, |f(x)/g(x)| < ε/ε = 1 if 0 < |x-a| < δ, and the limit of f(x)/g(x) as x approaches a is 0.
The following statement is true: If f'(1) exists, then the limit lim f(x) is f(1). This can be demonstrated by the definition of the derivative. If f'(1) exists, then the limit of the difference quotient, lim (f(x) - f(1))/(x-1), exists as x approaches 1. Thus, |f(x) - f(1)| < ε if 0 < |x-1| < δ. This implies that the limit of f(x) as x approaches 1 is equal to f(1).

Ko Tapu is a vertical limestone rock located off the coast of
Thailand. Peter sets up a camera in a boat to shoot some
footage of the top of Ko Tapu. The horizontal distance from
the camera to a point at the base of the rock is 135 feet, and
the vertical distance from the point at the base of the rock to
a point at the top of the rock is 66 feet, as shown in the
figure.
135 ft
What is the measure of the angle of elevation, to the nearest
degree, that Peter should set the camera so he can video the
top of the rock?
Answer: The angle of elevation that Peter should set the camera to is 35.3°, rounded to the nearest degree (35°).
Step-by-step explanation: To find the angle of elevation, we can use the tangent function. Let's call the angle of elevation "x". Then:
tan(x) = 66/135
We can find the value of x using the inverse tangent (arctan) function:
x = arctan(66/135)
Finally, we can convert the result from radians to degrees:
x = arctan(66/135) * 180/π
x = 35.3° (rounded to nearest degree)

The circuit starts at the final AND gate. It has two inputs, one from an OR gate and one from a NOT gate.
The OR gate has two inputs, p and q. If either p or q is high (1), the OR gate will output a high signal. If both p and q are low (0), the OR gate will output a low signal. In this case, we only have the value of p, which is high, so the output from the OR gate is also high.
The NOT gate has one input, q. It inverts the signal, so if q is high (1), the NOT gate will output a low signal (0), and if q is low (0), the NOT gate will output a high signal (1). We don't know the value of q, so we don't know the output from the NOT gate.
Finally, the AND gate takes the outputs from the OR gate and the NOT gate as its inputs. If both inputs are high (1), the AND gate will output a high signal (1). If either input is low (0), the AND gate will output a low signal (0). Since we don't know the output from the NOT gate, we can't determine the output from the AND gate.
So, to summarize, without knowing the value of q, we can't determine the output from the final AND gate.

The electric field at points on the y-axis above the uppermost charge can be calculated by finding the electric field due to each of the three charges and summing them. This calculation requires the use of Coulomb's law, which states that the force between two point charges is proportional to the product of the charges and inversely proportional to the square of the distance between them. The electric field due to a single charge is proportional to the charge and inversely proportional to the square of the distance from the charge to the point at which the field is being calculated.
By using the equations for the electric field due to each charge and the vector sum of their electric fields, an expression for the electric field at points on the y-axis above the uppermost charge can be obtained.

True. The proposition "for all x in set Z, either P(x) or Q(x) if and only if for all x in set Z, either P(x) or Q(x)" is a tautology. This means that the statement is always true, regardless of what predicates P(x) and Q(x) are.
The logical connective "if and only if" (written as "iff") is used to express that the two statements are logically equivalent. The symbol "V" represents the logical operator "or".
The tautology states that if either P(x) or Q(x) is true for some x in set Z, then the other statement, either P(x) or Q(x), must also be true. It follows that if either P(x) or Q(x) is false, then the other statement must also be false.

A seed company planted a floral mosaic of a national flag. The perimeter of the flag is 2,440 ft Determine the flag's width and length if the length is 340 ft greater than the width
The flag's width is ft. Its length is ft.
Answer:
width of the flag is 440 feet and the length is 780 feet
Step-by-step explanation:
Let's call the width of the flag "w". Then the length of the flag can be represented as "w + 340".
The perimeter of the flag is the sum of all four sides, so we can write the following equation:
2w + 2(w + 340) = 2,440
Expanding the second term on the left side and simplifying:
2w + 2w + 680 = 2,440
4w + 680 = 2,440
Subtracting 680 from both sides:
4w = 1,760
Dividing both sides by 4:
w = 440
So the width of the flag is 440 feet and the length is 780 feet (440 + 340).

Answer:
Step-by-step explanation:
Answer:
8 2/3
Step-by-step explanation:
Since she has 1/3 already, we need more. So here, we SUBRACT.
Subtract 9 with 1/3.
You'll get 8 2/3

What is the solution to 2log9(x)=log9 * + log9(x-2)
The solution to 2log9(x)=log9+ log9(x-2) is 4.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 2log9(x)=log^9(8)+log9(x-2)
Above equation can be written as below
Log₉x² = log₉8 + log₉(x-2)
Loga+Logb=Log ab from properties of logarithms
Log₉x² = log₉(8×(x-2))
Log₉x² = log₉8x-16
Log₉x² - log₉8x-16 = 0
Loga-logb=log(a/b)
Log₉(x²/(8x-16)) = 0
x²/(8x-16) = 9°
x² = 1 × 8x-16
x²-8x+16 = 0
x²-4x-4x+16 = 0
(x-4)(x-4) =0
x=4
Hence, the solution to 2log9(x)=log9+ log9(x-2) is 4.
