Answer:

Yes it is showing a function

Step-by-step explanation:

The correct answer is d) f^(-1)(x) = x/3, as it represents the Inverse relationship of y = 3x.

To find the inverse of a function, we need to switch the roles of x and y and solve for the new y.

The given function is y = 3x.

To find its inverse, let's swap x and y:

x = 3y

Now, solve this equation for y:

Dividing both sides of the equation by 3, we get:

x/3 = y

Therefore, the inverse function of y = 3x is f^(-1)(x) = x/3.

Among the given options:

a) f^(-1)(x) = 1/3x

b) f^(-1)(x) = 3x

c) f^(-1)(x) = 3/x

d) f^(-1)(x) = x/3

The correct answer is d) f^(-1)(x) = x/3, as it represents the inverse relationship of y = 3x.

Answer:

The answer is b.

Step-by-step explanation:

Take the areas of the two rectangles by multiplying the numbers. Then divide the two numbers, in this case, 33.75 and 15.

Answer:  b) The area of the image is 2.25 times larger.

Step-by-step explanation:  !.5 larger in each direction results in  1.5×1.5 which is 2.25 enlargment.

4.5 × 7.5 =33.75   3×5= 15

33.75÷15 = 2.25

Given the following equation:

Let's determine the value of x.

Step 1: Let's first transform 2 1/5 into an improper fraction.

Step 2: Let's simplify.

Therefore, x = 11

Keep in mind that for an equation with a constant that is a mixed number. Always transform it first into an improper fraction and apply the inverse property in simplifying or determining the value of x.

Since the sum of the numbers selected must exceed 1, we know that n must be at least 1. Therefore, the expected value of X is finite and is equal to 2.

The expected value of the count of numbers that are selected can be found using the geometric distribution, since it models the number of trials until a success occurs.

Let X be the number of numbers that are selected until the sum of all numbers exceeds 1. Then X has a geometric distribution with parameter p, where p is the probability of success on each trial, i.e. the probability that the sum of all numbers selected does not exceed 1.

Since the numbers are selected uniformly over [0, 1], the probability of success on each trial is given by the area under the curve between 0 and 1 after the first number is selected.

On the first trial, the probability of success is 1. On the second trial, the probability of success is the area under the curve between 0 and (1 - the first number selected).

On the third trial, the probability of success is the area under the curve between 0 and (1 - the sum of the first two numbers selected), and so on.

The expected value of X can be found using the formula for the expected value of a geometric distribution:

E(X) = 1/p

Since the expected value of the sum of n independent and identically distributed uniform [0, 1] random variables is n/2, we can use this to find p:

E(X_1 + X_2 + ... + X_n) = n/2

where X_1, X_2, ..., X_n are the n numbers selected.

So, p = 1 / (1 + n/2).

Finally, we can substitute this into the formula for E(X) to find the expected value of X:

E(X) = 1 / (1 - n/2) = 2 / (2 - n)

No, an isosceles triangle is not always a right triangle.

An isosceles triangle is a triangle that has two sides of equal length and two angles of equal measure. The two equal sides are known as the legs, and the angle opposite the base is known as the vertex angle.

A right triangle, on the other hand, is a triangle that has one right angle (an angle measuring 90 degrees). In a right triangle, the side opposite the right angle is the longest side and is called the hypotenuse.

While it is possible for an isosceles triangle to be a right triangle, it is not a requirement. In an isosceles triangle, the vertex angle can be acute (less than 90 degrees) or obtuse (greater than 90 degrees). Only if the vertex angle of an isosceles triangle measures 90 degrees, then it becomes a right isosceles triangle.

The product of factor 83.5 with 0.01 will be 0.835

What are mathematics operations?

• A mathematical operation is a function that converts a set of zero or more input values (also called "b" or "arguments") into a defined output value. The number of operands determines the operation's arity. Most commonly studied operations are binary operations (i.e., operations of arity 2), such as addition and multiplication, and unary operations (i.e., operations of arity 1), such as additive and multiplicative inverses.

• Zero-arity operations, or nullary operations, are constants, and mixed products are arity three operations, or ternary operations.

Here, the given statement is :

The product of a factor and 0.1 is 8.35

Let the factor be a then :

a x 0.1 = 8.35

a = 8.35/0.1

a = 83.5

The factor is 83.5

Now, the product of this with 0.01 will be :

83.5 x 0.01 = 0.835

Therefore, The product of factor 83.5 with 0.01 will be 0.835

The probability that the first sample following the mean shift produces a statistics that plots inside the control limits: β ^{m-1}( 1-β )

What is Probability?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Pr(shift found on mth sample) = Pr (not detected for (m-1) samples) x Pr (detected on mth)

= [ 1-(1-β) ]^{m-1} ( 1-β )

=β ^{m-1}( 1-β )

the anticipated number of subgroups to be examined before the shift is seen

ARL=1/{1-β}

Shift not detected on the first sample following the shift:

Pr = 1-(1-β) = β

Pr n successive samples that are outside of the control limits

= ( 1- β )^{n}

f) the likelihood that at least one out of n consecutive statistical plots will fall outside the control limit.

For the hexagon construction, every arc along the circle is connected, but for the equilateral triangle construction, every other arc along the circle is connected.

Step-by-step explanation: It makes sense because in the lesson you need to make 6 arcs for both hexagons and equilateral triangles. However hexagons have 2 times as much sides as triangles so to make a triangle you would have to make a line with every other arc. That means skip an arc each line you make. For A hexagon obviously because it has 6 sides you just draw the lines to connect all 6 arcs

Answer:

105/330 = 21/66 = 7/22

7/22 is the answer I think

Step-by-step explanation:

n(U) = 330

n(A) = 85

n(B) = 200

n(A n B) = 60

Now,

n(A U B) = n(A) + n(B) - n(A n B)

or, n(A U B) = 85 + 200 - 60

or, n(A U B) = 285 - 60 = 225

Now,

n(A U B) compliment = n(U) - n(A U B)

n(A U B) compliment = 330 - 225

so, n(A U B) compliment = 105

Now,

probability = 105/330

The probability of winning being consistently 10 percent less than expected indicates an unfair game or a biased system.

In a fair game or system, the probability of winning should be represented by the ratio of favorable outcomes to total outcomes. This is commonly expressed as a fraction a/b, where a represents the number of favorable outcomes and b represents the total number of possible outcomes.

However, if the probability of winning is always 10 percent less than expected, it suggests that there is a systematic bias or manipulation in the game or system. This bias could be intentional, designed to favor certain individuals or entities, or it could be due to some inherent flaw or error in the system.

The consistent 10 percent reduction in the probability of winning indicates that the game or system is not operating in a fair and unbiased manner. It raises concerns about fairness, integrity, and potentially unethical practices.

In summary, when the probability of winning is consistently 10 percent less than expected, it suggests the presence of an unfair game or biased system, where the outcomes are intentionally manipulated or influenced to give an advantage to certain parties.
