The experimental probability that the card selected was a K or 6 is option B.
What is Probability?
PrοbabiIity is the study οf the chances οf οccurrence οf a resuIt, which are οbtained by the ratiο between favοrabIe cases and pοssibIe cases.
Frοm the tabIe, we can see that the frequency οf drawing a K οr 6 is:
Frequency(K οr 6) = Frequency(K) + Frequency(6) = 4 + 10 = 14
The tοtaI number οf draws is 100.
The experimentaI prοbabiIity οf drawing a K οr 6 can be caIcuIated as:
ExperimentaI PrοbabiIity(K οr 6) = Frequency(K οr 6) / TοtaI number οf draws
ExperimentaI PrοbabiIity(K οr 6) = 14 / 100
ExperimentaI PrοbabiIity(K οr 6) = 0.14
Therefοre, the experimental prοbabiIity that the card seIected was a K οr 6 is 0.14 οr 14%. Optiοn b is the cοrrect answer.

A rectangle has a length of 40 cm and width of 21 cm. If a new rectangle is formed by adding the same amount to both the length and width the new area is 2262 cm. Find the dimensions of the rectangle.
Step-by-step explanation:
the area of a rectangle is
length × width.
so, the original area is
40 × 21 = 840 cm²
now, we add x to length and width, and we get :
(40 + x) × (21 + x) = 2262 cm²
let's do the multiplication :
40×21 + 40x + 21x + x² = 2262
840 + 61x + x² = 2262
x² + 61x = 1422
x² + 61x - 1422 = 0
a quadratic equation
ax² + bx + c = 0
has the general solution
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
a = 1
b = 61
c = -1422
x = (-61 ± sqrt(61² - 4×1×-1422))/(2×1) =
= (-61 ± sqrt(3721 + 5688))/2 =
= (-61 ± sqrt(9409))/2 =
= (-61 ± 97)/2
x1 = (-61 + 97)/2 = 36/2 = 18
x2 = (-61 - 97)/2 = -158/2 = -79
x2 would make the side lengths negative, and that does not make any sense for an actual shape, so
x = 18
is our valid solution.
that means the new length is
40 + 18 = 58 cm
the new width is
21 + 18 = 39 cm
If you get the answer correct ill give brainliest and thanks :))

Solve the following question
cot θ = 7/4 and θ in degrees = 29.744881 degrees. In this case, the adjacent side is 7 and the opposite side is 4.
What is cot?Cotangent (cot) is the ratio of the adjacent side to the opposite side of a right triangle.
In this right angle triangle, cot θ can be calculated using the formula
cot θ = adjacent/opposite.
In this case, the adjacent side is 7 and the opposite side is 4.
Therefore, cot θ = 7/4.
Now, to find theta in degrees, we can use the inverse cotangent function, arccot.
arccot (cot θ) = θ.
Therefore, θ = arccot (7/4).
Using a calculator, arccot (7/4) = 29.744881 degrees
Therefore, cot θ = 7/4 and θ in degrees = 29.744881 degrees.

Each of the given linear systems is in row echelon form.
Solve the system.
x + y − z + 2w=4
w=5
The solution as an ordered quadruple:
(0, -6 - z, z, 5)
HOW TO SOLVE A LINEAR SYSTEM?
The given linear system is:
x + y - z + 2w = 4
w = 5
This system is already in row echelon form. We can use back substitution to solve for the variables. Since we already know the value of w, we can substitute w = 5 into the first equation:
x + y - z + 2w = 4
x + y - z + 2(5) = 4
x + y - z + 10 = 4
Simplifying, we get:
x + y - z = -6
Now we have two equations:
x + y - z = -6
w = 5
We can solve for x, y, and z using the first equation. To do this, we can use the fact that the system is in row echelon form, which means that the leading coefficients are all 1 and there are no variables to the left of the leading coefficients. We can start by solving for z since it has a leading coefficient of 1:
z = x + y + 6
Next, we can use the second equation to solve for y:
y = -x - z - 6
Finally, we can use the third equation to solve for x:
x = y + z + 6
Substituting the expressions for y and z into the equation for x, we get:
x = (-x - z - 6) + (x + y + 6) + 6
Simplifying, we get:
2x = 0
Therefore, x = 0. Substituting this value into the expressions for y and z, we get:
y = -z - 6
z = y + 6
We have now solved the system and found that:
x = 0
y = -z - 6
z = y + 6
w = 5
We can write the solution as an ordered quadruple:
(0, -6 - z, z, 5)
where z can take on any value. This means that the system has infinitely many solutions, since we can choose any value for z and obtain a corresponding solution for x, y, and w.

Among 300 elementary school students,
258 said they like chocolate ice cream, 142
like vanilla ice cream and 102 like both.
Find the probability that a randomly
selected student likes:
A. Vanilla ice cream or chocolate ice
cream, but not both.
B. Neither of the 2 flavors.
C. Vanilla ice cream but not chocolate ice
cream.
To solve this problem, we can use the formula for probability:
Probability = (Number of favorable outcomes) / (Total number of outcomes)
A. To find the probability that a student likes vanilla or chocolate ice cream, but not both, we need to subtract the number of students who like both from the total number of students who like vanilla or chocolate:
Number of students who like vanilla or chocolate = 258 + 142 = 400
Number of students who like both = 102
Number of students who like only vanilla or only chocolate = 400 - 102 = 298
Probability = 298/300 = 0.9933
B. To find the probability that a student likes neither vanilla nor chocolate ice cream, we need to subtract the total number of students who like either or both flavors from the total number of students:
Total number of students = 300
Number of students who like vanilla or chocolate = 258 + 142 = 400
Number of students who like both = 102
Number of students who like neither flavor = 300 - 400 + 102 = 2
Probability = 2/300 = 0.0067
C. To find the probability that a student likes vanilla ice cream but not chocolate ice cream, we need to subtract the number of students who like both from the total number of students who like vanilla:
Number of students who like vanilla = 142
Number of students who like both = 102
Number of students who like only vanilla = 142 - 102 = 40
Probability = 40/300 = 0.1333

(a) The distance |PQ| is about 2,020.5 meters
(b) The speed of the aeroplane is about 60.6 km·h⁻¹
What is the speed of an object in motion?The speed of an object is a measure of how fast the object is moving, and the unit of speed is the distance per unit time. The speed of an object is the magnitude of the velocity vector of the object.
(a) The direction of flight of the aeroplane = Horizontally
Therefore;
PS = QR
PS = 600 m (the dimension on the diagram)
Therefore; QR = PS = 600 m
QR/KR = tan(21°)
KR = QR/tan(21°)
Therefore;
KR = 600/tan(21°) ≈ 1,563.05
PQ and SR are horizontal segments and PS and QR are vertical, therefore;
PQ ║ SR and PS ║ QR, therefore, quadrilateral PQRS is a parallelogram
PS and QR are vertical therefore, ∠PSR and ∠QRS are 90° angles, (definition of vertical segment PS is perpendicular to the horizontal segment segment SR)
Therefore, the parallelogram PQRS is a rectangle (Properties of a rectangle)
PQ ≅ SR (Facing sides of a rectangle)
∠SKR = 180° - (41° + 17°) = 122°
∠SKR = 122°
KR/sin(41°) = SR/sin(122°)
SR = sin(122°) × KR/sin(41°)
SR = sin(122°) × KR/sin(41°)
SR = sin(122°) × 1,563.05/sin(41°) ≈ 2,020.5
SR = PQ ≈ 2,020.5
|PQ| = 2,020.5 meters(b) The aeroplane flies from P to Q in 2 minutes
The conversion of the units are obtained as follows;

In order to determine which claims about the function are accurate, we shall plot the function's graph.
1) The function increases for all real x values greater than zero.
Since we get from the graph that function f(x) is decreasing for x<0.
This statement is false.

We must translate the distance from kilometres to centimetres in order to determine how many revolutions the wheel completes if the scooter travels 4.4 kilometres. 1 km equals 100,000 cm, so 4.4 km is equal to 440,000 cm.
Now, we can calculate the number of rotations by dividing the distance travelled by the wheel's circumference:
Distance travelled divided by circumference equals the number of revolutions.
440,000 cm / 28 cm divided by the number of revolutions
1566.99 revolutions were made.
Therefore if the scooter travels 4.4km, the wheel will turn about 1567 times.

The number of lightning strikes on a square kilometer of open ground in a year has mean 6 and standard deviation 2.4. (These values are typical of much of the United States.) The National Lightning Detection Network uses automatic sensors to watch for lightning in a sample of 25 randomly chosen square kilometers.
For the sample, what are the mean and standard deviation of ▁x, the mean number of strikes per square kilometer?
The mean of ▁x is 6 and the standard deviation of ▁x is 0.48.
What is standard deviation ?
Standard deviation is a measure of the amount of variation or dispersion of a set of data values from their mean (average) value. It tells us how much the individual data points differ from the mean. In other words, it measures the spread of the data around the mean.
A small standard deviation indicates that the data points are clustered closely around the mean, while a large standard deviation indicates that the data points are more spread out from the mean.
The formula for standard deviation is the square root of the sum of the squared differences between each data point and the mean, divided by the number of data points minus 1. It is denoted by the symbol σ for a population, and s for a sample.
The mean of the number of lightning strikes on a square kilometer of open ground in a year is 6, and the standard deviation is 2.4. Since we are interested in the mean of a sample of 25 square kilometers, the mean of the sample means, denoted by ▁x, can be found by:
Mean of ▁x = Mean of the population = 6
The standard deviation of the sample means, denoted by σ(▁x), can be found by dividing the population standard deviation by the square root of the sample size:
σ(▁x) = Population standard deviation / √Sample size
= 2.4 / √25
= 0.48
Therefore, the mean of ▁x is 6 and the standard deviation of ▁x is 0.48.

right triangle abc has area 32square root 3 cm squared. the measure of the angle a =30.
The length of BC is 16cm, the length of AB is 8√3cm, and the length of AC is 8cm. In a right triangle, the side opposite the right angle is the hypotenuse, while the other two sides are the legs.
Let's label the sides of the triangle ABC as follows:
BC is the hypotenuse, opposite to the right angle at B.
AB is a leg, adjacent to the angle A.
AC is a leg, opposite to the angle A.
Given that the area of the triangle is 32√3cm^2, we have:
(area) = (1/2) x (base) x (height)
Substituting the values we know, we get:
32√3 = (1/2) x AB x AC
Simplifying, we get:
AB x AC = 64√3
We also know that <A = 30 degrees, which means that <C = 60 degrees (since the angles in a triangle add up to 180 degrees).
Now we can use the trigonometric ratios to find the lengths of the sides. We have:
sin(30) = AC/BC
cos(30) = AB/BC
Solving for AC and AB, we get:
AC = BC x sin(30) = BC/2
AB = BC x cos(30) = BC√3/2
Substituting these values into the equation we got earlier, we get:
(BC/2) x (BC√3/2) = 64√3
Simplifying, we get:
BC^2 = 256
Taking the positive square root, we get:
BC = 16
Substituting this value into the equations we got for AB and AC, we get:
AB = BC√3/2 = 8√3
AC = BC/2 = 8
Therefore, the length of BC is 16cm, the length of AB is 8√3cm, and the length of AC is 8cm.
The complete question is:
right triangle ABC has area 32√3cm^2. The measure of <A = 30, m<B=90. What is the length of BC? AB? AC? Express all answers in simplest radical form.
