A sphere of radius "r" is cut by a plane "h" units above the equator. To find the volume of the solid (spherical segment) above the plane, we first need to find the height of the segment, which is (r - h).

A manufacturer drills a hole through the center of a metal sphere of radius R. The hole has a radius r. To find the volume of the resulting ring, we can use the formula for the volume of a cylindrical ring: [tex]\pi * (R^2 - r^2) * h[/tex], where h is the height of the ring. Since the hole goes all the way through the sphere, the height of the ring is equal to the radius of the sphere, R. So the volume of the ring is [tex]\pi * (R^2 - r^2) * R[/tex].

In the first problem, the volume of the solid (spherical segment) above the plane is [tex](1/3) * \pi * (r^2 - (r-h)^2) * h[/tex]. In the second problem, the volume of the resulting ring is [tex]\pi * (R^2 - r^2) * R.[/tex]

The binomial probability formula calculates the probability of getting exactly "x" successes in "n" independent trials, where each trial has a probability "p" of success.

In this case, the success is a French hen, with probability 0.81, and the number of trials is 3 (the number of hens).

The binomial coefficient "n choose x" represents the number of ways to choose "x" successes from "n" trials. It can be calculated as:

(n choose x) = n! / (x! * (n-x)!)

where n! is the factorial of n, which is the product of all positive integers up to n.

Plugging in the values from the problem, we have:

P(X=2) = (3 choose 2) * (0.81)^2 * (0.19)^1

= (3! / (2! * (3-2)!) ) * (0.81)^2 * (0.19)^1

= 3 * 0.81^2 * 0.19

= 0.324

So, the probability of getting exactly 2 French hens out of 3 is approximately 0.324.

If you measure a flower stem, its termination will be on the eleventh line from the 5 inch mark. The length of the blossom stem is 5 and 11/16 inches.

What is Measurement?

An object or event's attributes are quantified through measurement so that they can be compared to those of other things or occurrences. Measurement, then, is the process of establishing how big or little a physical quantity is in relation to a fundamental reference quantity of the same kind.

We have to measure 5 inches on scale we have to follow these steps:

Step 1: Get a ruler for inches. There will be 12 lines on the ruler that represent inches, indicating that it is an inch ruler. A foot is equivalent to 12 inches (0.305 m). Inches are divided into each foot. On the ruler, each inch is divided into 15 smaller marks for a total of 16 marks per inch.

Step 2: Find out what an inch is. 12 inch markings make up a ruler. The longest lines on the ruler serve to identify them, which are usually the numbered marks. Put one end of the nail, for instance, directly on the left side of the ruler when you need to measure it. The nail is 5 inches long if it terminates just over the long line next to the big number 5.

Step 3: Discover the 1/2 inch markings. The 1/2 inch marks, which are half as long as the inch marks, will be the second-longest lines on the ruler. Due to the fact that it is just half an inch, each 1/2 inch mark will be placed halfway between each inch number. This indicates that the 1/2 inch lines are located immediately between the 0 and 1 inch, 1 and 2 inch, 2 and 3 inch, and so on across the ruler. On a 12 inch ruler, there are a total of 24 of these marks.

Step 4 : Recognize the 1/4-inch markers. There will be a smaller line that represents a 1/4 of an inch halfway between each 1/2 inch line. These markers will indicate 1/4, 1/2, 3/4, and 1 inch inside the first inch. Despite having separate lines, the 1/2 inch and 1 inch markers are still included in the 1/4 inch measures since 2/4 of an inch equals half an inch and 4/4 of an inch equals one inch. On a 12 inch ruler, there are a total of 48 of these marks.

Step 5: Recognize the 1/8-inch scale. The tiny marks on the ruler that are situated between the 1/4-inch markers are the 1/8-inch marks. There are markers that stand for 1/8, 1/4, 3/8, 1/2, 5/8, 6/8, 3/4, 7/8, and 1 (or 8/8) of an inch between 0 and 1 inch. On a 12 inch ruler, there are 96 of these marks in total.

Step 6 : Recognize the 1/16-inch scale. The little lines at the midpoint of each 1/8 inch represent the 1/16 inch. These are the ruler's tiniest lines as well. The 1/16-inch mark is located on the very first line on the ruler's left side. There are symbols that stand for 1/16, 2/16, 1/8, 3/16, 4/16, 5/16, 6/16, 3/8, 1/2, 9/16, 10/16, 5/8, 11/16, 12/16, 3/4, 13/16, 14/16, 7/8, 15/16, and 16/16 of an inch, respectively, between 0 and 1 inch. There are 192 of these lines on the ruler in total.

Hence, If you measure a flower stem, its termination will be on the eleventh line from the 5 inch mark. The length of the blossom stem is 5 and 11/16 inches.

The model that would explain the utility is U(q) = - 0.02q^2 - 300 + 10q.

The maximum number of workers is 250 and utility is 950

From the question, we have the following parameters that can be used in our computation:

The total income as I(q) = 60q - 0.02q^2.

The total cost as C(q) = 300 + 50q.

The utility model can then be calculated as

U(q) = I(q) - C(q)

So, we have

U(q) = 60q - 0.02q^2 - 300 - 50q.

U(q) = - 0.02q^2 - 300 + 10q.

We have

U(q) = - 0.02q^2 - 300 + 10q.

Differentiate and set to 0

-0.04q + 10 = 0

So, we have

-0.04q = -10

This gives

q = 250 --- max workers

Recall that

U(q) = - 0.02q^2 - 300 + 10q.

So, we have

U(250) = - 0.02* 250^2 - 300 + 10 * 250

U(250) = 950 --- amount of utility

Answer:

next person to answer give them the brainly crow

Step-by-step explanation:

Answer:

Shape A: 647 (area) and 120 (perimeter)

Shape B: 192 (area) and 70 (perimeter)

Step-by-step explanation:

For shape A, we can find the area by:

- splitting the rectangle into 2 (horizontally), one that will have 16 and 12 as the sides, and another with 35 and 13 as the sides. Then, we can multiply the two rectangles and add them to find the area: (16*12) + (35*13) = 647

We can find the perimeter by:

- adding all the numbers: 25+16+12+19+13+35 = 120

For shape B, we can apply the same method as shape A:

- Area: (12*8) + (8*12) = 192

- Perimeter: 12+8+8+7+7+8+8+12 = 70

Answer:

Shape a) Area: (25*16)+(19*13)=400+247=647

 Perimeter: 16+12+19+13+35+25=120

Shape b)Area: (12*8)+(12*8)=96+96=192

              Perimeter: 12+8+7+8+12+8+7+8 = 70

there is only one row so that adds 2 dots and then you multiply the number of squares by 2 then add 2 to the product

Answer:

a) 22 dots

b) 51 squares

c) Number of dots = 4 + 2 x (number of squares - 1)

Step-by-step explanation:

Actually, in this question you are better off solving c) first for the formula and then using it to solve a) and b)

Let's look at the relationship between squares and dots:

Number of squares                 Number of dots
              1                                                 4

              2                                                6

              3                                                8

You can see that as the number of squares increases by 1, the number of dots increases by 2 with 4 dots as the starting point

We can easily come up with a formula by treating this as an arithmetic sequence.

The number of dots represents the term # and the number of dots the actual term value

The difference between consecutive terms is 2 and is called the common difference (d)

The nth term will be referred to using  aₙ

So we have

a₁ = 4

a₂ = 6

a₃ = 8

The nth term of any arithmetic sequence is

aₙ = a₁ + d(n-1) where d is the common difference

This is the answer to c). Translating to dots and squares we get

Number of dots = 4 +  2 x (number of squares - 1)

a) Use the formula

a₁₀ = 4 + 2(10-1) = 4 + 2 x9 = 4 + 18 = 22 dots

b) Here we are given the value of term = 104

Substituting we get

104 = 4 + 2(n-1)

104-4 = 2(n-1)

100 = 2(n-1)

n-1 = 100/2 = 50

n = 51

That means the there are 51 squares in the diagram which has 104 dots
