The probability that the person also buys cereal at least once a month, given that a randomly chosen person eats breakfast almost every day is 53/64

Random sample is the way to choose a number or sample in such a manner that each of the sample of the group has an equal probability to be chosen.

A survey asked about the number of people who eat breakfast almost every day (B) and the number of people who buy cereal at least once a month (C).

The results of the survey are shown in the Venn diagram as,

Therefore, for circle B, it can be given as,

[tex]n(B)=11+53=64[/tex]

Similarly, for the circle C,

[tex]n(C)=53+4=57[/tex]

As the intersection of circle B and C contains 53,

[tex]n(BC)=53[/tex]

Now the probability that the person also buys cereal at least once a month, given that a randomly chosen person eats breakfast almost every day,

[tex]P(C|B)=\dfrac{P(BC)}{P(B)}\\P(C|B)=\dfrac{n(BC)}{n(B)}\\P(C|B)=\dfrac{53}{64}[/tex]

Hence, the probability that the person also buys cereal at least once a month, given that a randomly chosen person eats breakfast almost every day is 53/64

It can be deduced that the price-response function associated with the situation will be P = MWTP =  -e⁻ λ.

A function, in mathematics, is a relationship that exists between one variable that is, the independent variable and the dependent variable.

When the willingness-to-pay distribution of a product is a negative exponential distribution with parameter λ, the price-response function associated with it will be:

dWTP/dλ = -e⁻ λ

P = MWTP =  -e⁻ λ

Answer: 10 1/3

Jonathan first got the steps right, however, he was incorrect because he added the denominators together. Since the two denominators are the same, the sum will also have a denominator of 3, not 6. In his other steps, he was correct; 7 + 2 = 9, 2 + 2 = 4. Thus, making 9 4/3 or 10 1/3.

Step-by-step explanation:

cost of a pass for a week (without equipment rental) = 7 x 25 = $175

Therefore, cost of just renting the equipment for the week = 199 - 175 = $24

ETA: As an algebraic equation

Let x = number of days

Let y = cost of renting the equipment for a week

y = 199 - 25x

Answer:

Design 1: $449.45

Design 2: $522.60

Design 3: $318.25

Design 3 as it's the cheapest

Step-by-step explanation:

Design 1

Area of a trapezoid = 1/2(a + b)h (where a and b are the bases and h is the height)

Given the slanted side = 3.5

Height = √(3.5² - 1²) = (3√5)/2

⇒ area of design 1 = 1/2(5 + 3) × (3√5)/2 = 6√5 = 13.42 m²

⇒ cost = 13.42 x 33.5 = $449.45

Design 2

Area of a triangle = 1/2 x base x height

Area of a rectangle = width x length

Area of a 6-sided regular polygon = 4 triangles + rectangle

⇒ area of design 2 = 4(1/2 × 1.4 × 2.0) + (2.5 × 4) = 15.6 m²

⇒ cost = 15.6 x 33.5 = $522.60

Design 3

Area of a trapezoid = 1/2(a + b)h (where a and b are the bases and h is the height)

⇒ area of design 3 = 1/2(3 + 2) × 2 + 1/2(3 + 1.5) × 2 = 9.5 m²

⇒ cost = 9.5 x 33.5 = $318.25

Constant 'k' has the value in the form of factored after factorization, the provided polynomial equation is 2.

Polynomial equations is the expression in which the highest power of the unknown variable is n (n is real number).

The factor of a polynomial is the terms in linear or equation form, which are when multiplied together, give the original polynomial equation as result.

The given polynomial equation in the problem is,

[tex]8x^3 +6x^2 - 32x - 24[/tex]

The factor of the polynomial equation are given as,

[tex]2(x+ k)(x - k)(4x +3)[/tex]

First find out the factors to compare and find the value of k.The above equation has the unknown variable x and the highest power of this unknown variable is 3.

Take out the highest common factor 2, which can divide each term of the above equation (8, 6, -32, -24). Thus,

[tex]2(x+ k)(x - k)(4x +3)=2(4x^3 +3x^2 - 16x - 12)[/tex]

Take out the highest common factor to make the groups as,

[tex]2(x+ k)(x - k)(4x +3)=2(x^2(4x +3) - 4(4x + 3))\\2(x+ k)(x - k)(4x +3)=2(4x +3) (x^2 -4)\\2(x+ k)(x - k)(4x +3)=2(4x +3) (x^2 -2^2)[/tex]

Use the property of difference of the square for the (x²-2²) term as,

[tex]2(x+ k)(x - k)(4x +3)=2(4x +3) (x +2)(x-2)\\2(x+ k)(x - k)(4x +3)=2(x +2)(x-2)(4x +3)[/tex]

On comparing the two equation, we get the value of k as 3. Thus, the value of the constant 'k' in the factored form factorization the provided polynomial equation is 2.

There is an open circle on –6. 5 and the arrow points to the right. The correct options are A and E.

Inequality is simply a type of equation that does not have an equal sign in it. Inequality is defined as a statement about the relative size as we will as is used to compare two statements.

The given expression is [tex]\rm x > -6.5[/tex].

It means the value of x is more than -6.5.

Since the sign of equality is not there in the equation then at -6.5 will be an open circle. And the arrow points to the right.

The americium is represented as 1. Every 432 years it decreases by 50%.

First half-life:

432 years.

0.50 (1/2) of americium remains after 432 years.

Option B is correct.

Answer:

B.  g(x) = (2x)^2

Step-by-step explanation:

See attached image.

The graph of the function g ( x ) = ( 2x )² is plotted

Graphs behave differently at various x-intercepts. Sometimes the graph will cross over the x-axis at an intercept. Other times the graph will touch the x-axis and bounce off.

Identify the even and odd multiplicities of the polynomial functions' zeros.

Using end behavior, turning points, intercepts, and the Intermediate Value Theorem, plot the graph of a polynomial function.

The graphs cross or are tangent to the x-axis at these x-values for zeros with even multiplicities. The graphs cross or intersect the x-axis at these x-values for zeros with odd multiplicities

Given data ,

Let the parent function be represented as f ( x )

Now , the value of f ( x ) is

f ( x ) = x²

Now , the graph of the function is g ( x )

where g ( x ) = 4x²

And , the point P ( 1 , 4 ) lies on the graph

when x = 1

g ( 1 ) = 4

Hence , the graph is plotted and g ( x ) = 4x²

Hi There!

Given:

To Find:

How many placemats can Mandy make, if she has 200 ft of ribbon?

Solve:

200÷30≈7

Thus, she can make 7 placemats.

[tex]\huge\textbf{TheStarryNights}[/tex]

Answer:

C. 6 placemats

Step-by-step explanation:

Mindy has 200 feet of ribbon and each placemat requires 30 feet of ribbon.

Now, we need to divide 200 by 30.

200/30 ≈ 6.66666666667

Now, what whole number is before 6.66666666667?

6.

Now, what whole number is after 6.66666666667?

7.

What is 7 x 30?

210.

What is 6 x 30?

180.

Mindy has only 200 feet of ribbon, so she can't make 7 placements because 200 < 210, but she can make 6 placements because 200 > 180.
