Option (b), “a continuum of possible values” is the correct option.
The concepts of continuous probability distribution and normal distribution are used here to solve this problem.
The continuous probability distribution can be defined as the probability distribution of a continuous random variable. Normal distribution is used for finding the probability of a continuous variable when the data is more or less symmetric. The probability of being less than or more than some value can be calculated by calculating the area of the curve to the left of that value.
The probability of a continuous random variable will assume a particular value is zero. Consider a continuous random variable, which follows normal distribution with a mean, and a standard deviation, which can be represented as to calculate the probability for a random variable, convert the variable into a standard normal variable by the transformation:
Option (a), “an array of individual values” is incorrect because the continuous probability distribution does not contain an array of individual values. Option (c), “a list of possible values” is incorrect because it is not just a list of possible values. Option (d), “counts” is incorrect because the counts is not a characterized by the continuous probability.
Probability is defined as a task that cannot be completed.True or FalseFalse
Probability can be defined as the likelihood or chance of an event occuring. Probability is a branch of Mathematics that deals with the calculation on the chances of happening of a particular event.
For instance, the probability that a student will pass an exam is 1/2.
The students has a total of two possible outcomes, pass or fail.So, the probability of one outcome = 1/total outcome which is 1/2

If FG = 2x, GH = x-1, and FH = 5 what is GH?
Answer:
GH = 1
Step-by-step explanation:
Finding the value of x,
→ FG + GH = FH
→ 2x + x - 1 = 5
→ 3x = 5 + 1
→ x = 6/3
→ [ x = 2 ]
Now the value of GH is,
→ GH = x - 1
→ GH = 2 - 1
→ [ GH = 1 ]
Hence, the value is 1.
Find the distance between the two points.
(-9,9) and (-16,33)
The distance is
(Type an exact answer, using radicals as needed.)
The distance between the given two points is 25.
The coordinates of two points given to us are (-9, 9) and (-16, 33).The length of the line segment connecting two places is defined as the distance between them. The length of the line segment connecting the specified coordinates can be used to compute the distance between two locations in coordinate geometry.The distance (d) between the two points whose coordinates are (x1, y1) and (x2, y2) is given by the formula:d² = (x2-x1)² + (y2-y1)² We will apply the above formula.d² = (-16-(-9))² + (33-9)²d² = (-16 + 9)² + (33-9)²d² = (-7)² + (24)²d² = 49 + 576d² = 625d = √625d = 25Thus, the distance between the given points is 25.To learn more about distance, visit :

AE = EB and CF = FB
ca = 18
de = 7
cb = 14
fe = [?]
Answer:
by comparing the two triangles,
we take the ratio of each side to be equal
Step-by-step explanation:
By comparing the sides of the triangles,
we take the ratio of each sides to each other
de/cb = fe/ca
de.ca = fe.cb
fe = (de.ca)/cb
fe = (7* 18)/14
fe = 9
The measure of side FE of triangle DEF is FE = 9
What are similar triangles?If two triangles' corresponding angles are congruent and their corresponding sides are proportional, they are said to be similar triangles. In other words, similar triangles have the same shape but may or may not be the same size. The triangles are congruent if their corresponding sides are also of identical length.
Corresponding sides of similar triangles are in the same ratio. The ratio of area of similar triangles is the same as the ratio of the square of any pair of their corresponding sides
Given data ,
Let the first triangle be represented as ABC
Now , let the second triangle be DEF
And triangle ABC and DEF are similar triangles
So , corresponding sides of similar triangles are in the same ratio
And , AE = EB and CF = FB
From the similar triangle theorem ,
EF / AC = DE / CB
Substituting the values in the equation , we get
EF / 18 = 7 / 14
Multiplying by 18 on both sides of the equation , we get
EF = ( 7 x 18 ) / 14
EF = 18/2
EF = 9
Therefore , the value of EF is 9
Hence , the measure of side EF is 9

A sampling interval of 5 (selecting every fifth unit) was used to select a sample from a population of 1000. how many elements are to be in the sample?
200 elements are required to be in the sample.
What is a sampling interval of a population?The sampling interval is the frequency with which data is collected. The sampling interval is computed by the division of the total population size by the required sample size.
So, from the information given:
The total population N = 1000The sampling interval (i) = 5The elements that are required to be in the sample i.e. the sample size (n) can be computed by using the formula:
[tex]\mathbf{i = \dfrac{N}{n}}[/tex]
[tex]\mathbf{ n= \dfrac{N}{i}}[/tex]
[tex]\mathbf{ n= \dfrac{1000}{5}}[/tex]
n = 200 elements.

How to find the principalThe principal is the amount of money to be paid for the automobile which is $27,890.
How to find the interest
from simple interest formula = ( principal * time * rate ) / 100
given data
principal = $27,890
time = 66 months

We then divide that expression over 5 to get the quotient.Take any number x, and subtract off 7. For instance, if x = 10, then x-7 = 10-7 = 3, which shows that 3 is 7 less than 10.The term "quotient" means "result of division". So we divide 4 over 'e'The expression 9+x is the sum of 9 and some unknown number.

The power of a number tells us how many times that number must be multiplied. Exponents and indexes are other names for powers. For instance, 8² denotes "8 squared," "8 squared," or just "8 squared."
A power is just an expression that denotes repeatedly multiplying the same number or factor. The exponent value depends on how frequently the base has been multiplied by itself.
For instance, 8 x 8 x 8 x 8... times is 8. The phrase 8n above is pronounced as 8 raised to the power n. As a result, exponents are also sometimes referred to as power or indices.

To put it another way, the conclusion "if A, then B" is inferred by building a proof of the claim "if not B, then not A" instead. This method is frequently chosen if the contrapositive is more straightforward to establish than the first conditional statement.

How to determine the probability of not drawing a queen from a standard deck of 52 cards?In a standard deck of 52 cards, we have
Total number of cards = 52
Queen cards = 4
The probability of not drawing a queen from a standard deck of 52 cards is calculated as
P = 1 - P(Queen)
Where
P(Queen) = Queen cards/Total number of cards
So, we have
P(Queen) = 4/52
Substitute P(Queen) = 4/52 in the equation P = 1 - P(Queen)
This gives
P = 1 - 4/52

What is defined as the parallelogram?A parallelogram is just a quadrilateral with two parallel sides (and therefore opposite angles equal).
A rhombus is a quadrilateral to equal sides, while a rectangle is a parallelogram with all right angles. Furthermore, because a square is a degenerate situation of a rectangle, rectangles and squares are both special kinds of parallelograms.A parallelogram's opposite sides are all the same length.A parallelogram's adjacent or adjoining angles add up to 180°.A parallelogram's diagonals cross each other.For the given case.
The sides of the 3 cm and 5 cm. As, these two side are the adjacent sides of the parallelogram, the diagonal formed will be the closing side of the triangle.
As, the diagonal is the longest side of the triangle, thus its value must be greater than other side.
This is possible with the diagonal values of 10 cm and 8 cm.
Thus, 10 cm and 8 cm are the correct values for the diagonal of parallelogram.
