If the two spinners below are spun, what is the probability that the numbers will add to more than 4?

Answer: 1. No, because figure 1 is 5 squares and figure 2 is 6 squares

Step-by-step explanation:

The measure of ∠K is 72°.

To find the measure of ∠K in ΔJKL, we can use the Law of Cosines. The formula is:

cos C = (a^2 + b^2 - c^2) / 2ab where C is the angle opposite the side of length c.

In this case,

Plugging in the values, we get:

cos C = (720^2 + 640^2 - 520^2) / 2 * 720 * 640

cos C = 0.4756

Finally, to find the measure of ∠K, we use the inverse cosine function:

∠K = cos^-1 (0.4756)

∠K = 72.22°

Rounding to the nearest degree, ∠K = 72°.

The area of the cone that was painted black is given by 47.66 ft²

For a right circular cone of radius 'r', height 'h', and slant height 'l', we have; Curved surface area of the right circular cone = π r l. The total surface area of a right circular cone = π(r + l) r. The volume of a right circular cone = 1/3π r2 h.

Given here: The height of the cone is 12 feet and circumference of the base of the cone is 8π

We know the base of the cross section is always a circle.

Thus  we have

2πr=8π

2r=8

r=4

Now slant height of the cone is given using the pythagoraes theorem as follows

l=[tex]\sqrt{4^2+12^2}[/tex]

=12.65 feet

Thus lateral surface area of the cone is L= πrl

                                                                   =3.14×4×12.65

                                                                   =158.884 ft²

Now we can infer from the question that 30% of the lateral surface area is painted black thus

Area painted black is = 30%×158.884

                                    =0.3×158.884

                                    =47.66 ft²

Hence, The area of the cone that was painted black is given by 47.66 ft²

The discrete probability distribution of the number of successes in a series of n independent experiments is called the binomial distribution with parameters n and p in probability theory and statistics.

What is the binomial distribution?

The binomial distribution formula aids in determining the likelihood that "x" successes will occur in "n" separate trials of a binomial experiment. Recall that there are two possible outcomes for the statistics probability distribution known as the binomial distribution. The binomial distribution in probability theory has two parameters, n and p. When the probability distribution satisfies the following conditions, it becomes a binomial probability distribution. Each experiment may only yield two results, or results that can be reduced to two results. These results could result in success or failure. There must be a specific number of trails. Each trial's results must be distinct from one another.

Additionally, each trial's likelihood success rate must remain constant.

Answer:

X=. 1. X=. 2

Step-by-step explanation:

The first story (movie theater) has the equation 6(x+3)= 24. The equation for the juice story is 3(x+6)=24 . The x in the move theater story is the cost of each ticket. The x in the juice story is the amount of juice poured to each friend originally (before the extra 6 ounces). The solution to the movie theater story is 6((1)+3)=24. So x is one is the first story.In the juice story, 3((2)+6)= 24. So x is two. The solution tells me that in the movie theater story that each ticket cost 1 dollar. In the second story, it tells me that 2 ounces of juice where poured to each freind originally. So each freind got a total of 8 ounces of juice.

Step-by-step explanation:

I see only 2 stories and equations.

a.

6(x + 3) = 24

is for the first story (6 show tickets and snacks).

3(x + 6) = 24

is for the second story (juice for 3 friends).

b.

in the first story it is the price of one ticket to the show.

in the second story it is the original amount of juice each friend gets before adding 6 oz.

c. and d.

6(x + 3) = 24

6x + 18 = 24

6x = 6

x = 1

each ticket to the show was $1.

3(x + 6) = 24

3x + 18 = 24

3x = 6

x = 2

each of the 3 friends got first 2 oz of juice, before they each got additional 6 oz. so, ultimately, each friend got 8 oz.

The website is advertising a 46% discount on the jacket, meaning that Farah will pay 46% less than the original price if she decides to buy it now.

A discount is a reduction in the original price of an item, allowing the customer to purchase it for less than the original price.

To calculate the discount mathematically, we can use the following formula:

Discounted price = Original price * (1 - discount percentage)

Let's assume the original price of the jacket is P dollars.

The discount percentage is 46%, which can be written as a decimal 0.46. To find the discounted price, we need to multiply the original price by (1 - discount percentage), which is (1 - 0.46) = 0.54.

So, the discounted price after the 46% saving will be P * 0.54 dollars.

In other words, Farah will pay 0.54 times the original price, P, to buy the jacket with the advertised 46% saving.

A frequency table is a simple tabular representation of the number of times a particular value or range of values appears in a data set.

It lists the values in one column and the corresponding frequencies in another column. For example, if we have data on the heights of a group of people, a frequency table could list the heights (in cm) in one column and the number of people with that height in the other column.

A frequency distribution is a graphical representation of the same information as a frequency table. It shows the number of occurrences of values in a data set by grouping the values into classes or intervals, and then plotting the frequency of each class or interval. For example, a histogram is a type of frequency distribution where the data is divided into equal-width intervals and the height of each bar represents the frequency of the data that falls within that interval.

A frequency table can be used for both qualitative and quantitative data, whereas a frequency distribution can only be used for quantitative data. This is because the classes or intervals used in a frequency distribution require a numerical representation of the data, which is not possible for qualitative data.

In order to find the perimeter or distance around the rectangle, we need to add up all four side lengths. This can be done efficiently by simply adding the length and the width, and then multiplying this sum by two since there are two of each side length.

Perimeter = (length+width)×2 is the formula for the perimeter.

The perimeter of a rectangle is the sum of the lengths of all four sides.

If the sides of a rectangle have lengths of 6 cm and 5 cm, then the perimeter can be calculated as follows:

The horizontal asymptote is y = X, and the vertical asymptotes are x = 2 and x = 1.

A curve is a continuous, smooth, and often repeating shape in the plane or in space. It is a geometric object that can be described mathematically by an equation or a set of points.

In mathematics, curves are used to model real-world phenomena and to study geometric and mathematical properties. For example, curves can be used to describe the shape of objects, the path of moving objects, or the graph of a mathematical function.

There are many types of curves, including lines, circles, ellipses, parabolas, hyperbolas, and spirals, among others. Each type of curve has unique properties and characteristics, and they are studied and used in different ways in different fields of mathematics and science.

The horizontal asymptotes are found by examining the degree of the numerator and denominator when x approaches infinity or negative infinity.

Since the numerator is of degree 3 and the denominator is of degree 2, the horizontal asymptote is y = X3 - x / x² – 3x + 2 = X.

For the vertical asymptotes, we look for the values of x that make the denominator equal to zero and the numerator either equal to zero or undefined.

The denominator x² – 3x + 2 = 0 has roots at x = 1 and x = 2.

At x = 1, the numerator x³ - x = 0, so the function has a hole at x = 1 and y = 0.

At x = 2, the function is undefined, so x = 2 is a vertical asymptote.

Thus, the horizontal asymptote is y = X, and the vertical asymptotes are x = 2 and x = 1.
