Answer:
4/7
Step-by-step explanation:
first simplify it to 12/21 when you divide both sides by 2
then simplify to 4/7 when you divide both sides of 12/21 by 3
Answer:
4/7
Step-by-step explanation:
Both numbers in the fraction are divisible by 6, so to simplify it, divide each number by 6:
24/6 = 4
42/6 = 7
Then, put these 2 numbers in fraction form:
4/7
So, 4/7 is the simplified fraction.
In a card game, the probability that you will have a hand with five cards in the same suit is about 14%. The dealer wants to know the probability for a player to be dealt this type of hand in one of the first three hands. Should a geometric probability density function or a cumulative distribution function be used? Explain.
(A) A geometric cumulative distribution function should be used because the question states that the probability for having this type of hand is about 14%.
(B) A geometric probability density function should be used because the question states that the probability for having this type of hand is about 14%.
(C) A geometric cumulative distribution function should be used because the question asks for the probability of having a hand with five cards in the same suit in one of the first three hands.
(D) A geometric probability density function should be used because the question asks for the probability of having a hand with five cards in the same suit in one of the first three hands.
(E)There is not enough information to be to able to determine whether a geometric probability density function or a cumulative distribution function should be used.
Answer:
C) A geometric cumulative distribution function should be used because the question states that the probability for having a hand with three of a kind is about 6%.
Step-by-step explanation:
A geometric cumulative distribution function should be used because the question states that the probability for having a hand with three of a kind is about 6%.
A geometric cumulative distribution function should be used because the question asks for the probability of having a hand with five cards in the same suit in one of the first three hands
Option C is the correct answer.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
We have,
The geometric cumulative distribution is a discrete likelihood conveyance where the random variable describes the quantity of the expected Bernoulli trial.
A Bernoulli trial is an experiment that can have just two results.
Success and failure.
Now,
We are interested in the first success in the three chances, which is a distribution function of a geometric distribution.
Now,
The probability of having a hand with five cards in the same suit in one of the first three hands.
This is a geometric distribution.
Thus,
A geometric cumulative distribution function should be used.

what is the coefficients of x² in (2-3x) (x²-5)
Answer:
+2
Step-by-step explanation:
=> \((2-3x)(x^2-5)\)
=> \((2x^2-10-3x^3+15x)\)
Arranging it in descending order
=> \(-3x^2+2x^2+15x-10\)
So, the coefficient of x² in this expression is +2
This depends if you are supposed to simplify the binomials first:
If you leave it in the form provided then the coefficient would be 1
However, you can multiply the binomials together in order to simplify the expression:
\((2 - 3x)( {x}^{2} - 5)\)
\((2 \times {x}^{2} ) + (2 \times - 5) + ( - 3x \times {x}^{2} ) + ( - 3x \times - 5)\)
\( { - 3x}^{3} + {2x}^{2} + 15x - 10\)
Which then shows the coefficient would be 2
So it all depends on the directions provided, I would assume the correct answer is 2 if the directions are the exact same as provided on Brainly.

State whether you believe the two variables are correlated. If you believe they are correlated, state whether the correlation is positive or negative. The repair bills of a car and its fuel consumption.
Answer:
I believe they are correlated: positive correlation.
Step-by-step explanation:
The higher the repair bills of a car, it means maybe having bad fuel injectors, will cause bad mileage allowing the car to consume more fuel. It is like say the inexorable decline of a car in areas including minor wears and incorrect adjustment etc impairs fuel economy. Thus, the higher the repair bills, the higher the fuel consumption. This is an example of a positive correlation. This means the value of y increases as there is an increase in the value of x.

Answer:
( c+a, b)
Step-by-step explanation:
The length of the horizontal line is c by taking points D and C
( c-0) =c
So the length of line AB must also be c if it is a parallelogram
Let the coordinate of B be (x,y)
(x-a) =c
x = c+a
The height of the parallelogram is b by taking the difference of the y coordinates from A and D
A -D = b-0 = b
This must be the same form B and C
y -0 = b
y = b
The coordinates of B is ( c+a, b)

Applying the alternate interior angles theorem, the measure of angle FBC is determined as: 67°.
What is the Alternate Interior Angles Theorem?If two angles are alternate interior angles formed along a transversal on two parallel lines, then their measures are congruent or the same.
What are Angles on a Straight Line?Angles on a straight line are angles that lie along a straight line, and the sum of the angles equals 180 degrees.
Given the following:
m∠BFC = 75°
m∠GFC = 38°
∠EFB, ∠BFC, and ∠GFC are angles on a straight line, therefore:
m∠EFB = 180 - m∠BFC - m∠GFC
Plug in the values
m∠EFB = 180 - 75 - 38
m∠EFB = 67°
Find the measure of angle FBC:
Angles FBC and EFB are alternate interior angles, therefore:
m∠FBC = m∠EFB = 67° [alternate interior angles theorem]
m∠FBC = 67°
In summary, using the alternate interior angles theorem, the measure of angle FBC is determined as: 67°.

Two stockpots are similar cylinders. The smaller stockpot has a height of 10 inches and a radius of 2.5 inches, the volume of larger one is 628.32 cubic inches.
We know that, to find volume:
Volume = π * \(r^2\) * h
For the smaller stockpot:
Radius (r) = 2.5 inches
Height (h) = 10 inches
Volume = π * (2.5)² * 10 ≈ 196.35 cubic inches
For the larger stockpot:
Radius (r) = 2.5 inches
Height (h) = 16 inches
Volume = π * (2.5)² * 16
≈ 628.32 cubic inches
Thus, the volume of larger one is 628.32 cubic inches.

Are all intersecting lines perpendicular? Draw a picture to help explain your answer
Not all intersecting lines are perpendicular.
What are perpendicular lines?Perpendicular lines require a 90-degree angle of intersection, creating the formation of right angles.
Nonetheless, unlike perpendicular lines that necessitate exactly 90 degrees of intersections, other types of driven lines can be at varying angles beside these.
As such, it is critical to highlight that in general intersecting lines come with different angles of intersection, and only those featuring exact 90-degree angle of intersection become normal cases of intersecting lines, becoming one among many subtypes existing today.

How to calculate the composite functionsFrom the question, we have the following equations that can be used in our computation:
h(x) = x² + 3
f(x) = 3/4x
From the above, we have
(h o h)(x) = h(h(x))
So, we have
(h o h)(x) = (x² + 3)² + 3
Also, we have
(f o f)(x) = 3/[4(3/4x)]

How to find the recursive relation ?A sequence of values is defined by a mathematical equation termed as a recursive relation, also known as recursive relation. It derives current value(s) through specified initial value(s) and previous value dependent rule(s). In essence, it generates numeric sequences.
Note that every individual unit can be derived by multiplying the preceding one with a rising integer, and subsequently subtracting a descending integer:
