Answer: its Square but the top one is rectangle

Answer:

  735.2 cm³

Step-by-step explanation:

You want the volume of a sphere with diameter 11.2 cm.

The volume of a sphere is given by the formula ...

  V =4/3πr³

We know that the radius r is half the diameter d, so we can write this as ...

  V = (4/3)π(d/2)³ = 4/24πd³ = (π/6)d³

With the given values, this is ...

  V = (3.14/6)(11.2 cm)³ ≈ 735.2 cm³

The sphere's volume is about 735.2 cm³.

Answer: 9 oranges: bananas

Step-by-step explanation:

The ratio is 3 oranges: 2 bananas. They add up to 5 fruits, so some possible values are 5, 10, 15, 20, 25. We need a value between 8 and 16. This means that we need 15/5 = 3 portions of fruits and since the ratio is 3:2

We multiply this by the original ratio to get 9 oranges: 6 bananas

Answer:

6:4

Step-by-step explanation:

3+2=5, but 5 is not enough so we multiply 3 and 2 to make 6 and 4. Now 6+4= 10 which is between 8 and 16 as we need. So the answer is 6:4

Step-by-step explanation:

You can use the fact that number of breads purchased cannot be negative since a customer either buys them or not and usually do not sell to the shopkeeper.(if somehow they end up selling to shop owner, then yes that will go in negative, but we'll assume it is wrong in most cases as generally shop owners are there to sell stuffs).

The third table of values matches the equation and includes only viable solutions.

It is talking about those solutions which are seen in real world. As stated above, a customer either buys the bread or not, thus number of breads sold will be either positive or 0(in case of no selling). Thus, we cannot have number of breads as negative.

Such solutions which are correct in the real world context here are called here as viable solutions.

For first table, the number of breads are in negative, thus it is not going to have viable solution.

For second table, we have:

b = 0 thus c = 3.5b = 3.5 times 0 = 0 which is correctly given in second column.

b = 0.5, thus c = 3.5b = 3.5 times 0.5 =1.75 which is correctly given.

b = 1, thus c= 3.5 times 1 = 3.5 which is correctly given

b = 2001.5 thus c = 3.5 times 2001.5  = 7005.25 which is not correctly given, thus wrong.

For third table, we have:

b = 0, thus \(c = 3.5 \times 0 = 0\), correctly given in second column.

b = 3, thus \(c = 3.5 \times 3 = 10.5\), correctly given.

b = 6, thus \(c = 3.5 \times 6 = 21\), correctly given.

b = 9, thus \(c = 3.5 \times 9 = 31.5\), correctly given.

Thus, the third table of values matches the equation and includes only viable solutions.

Answer:

its c to be exact

Step-by-step explanation:

To find the cumulative probability distribution function (CDF) F(y), we need to integrate the given PDF f(y) from 0 to y:

F(y) = integral of f(y) dy from 0 to y

= integral of c*y*(1-y)^2 dy from 0 to y   (substituting c=30 from part a)

= 30*integral of y*(1-y)^2 dy from 0 to y

To integrate this, we can use integration by substitution. Let u = 1 - y, then du/dy = -1 and y = 1 - u. Substituting, we get:

F(y) = 30*integral of (1-u)*u^2 * (-du) from 0 to 1-y

= 30*integral of u^2 - u^3 du from 0 to 1-y

= 30*[u^3/3 - u^4/4] evaluated at 0 and 1-y

= 10*(1 - (1-y)^3 - 3(1-y)^4/4),   0 <= y <= 1

Therefore, the cumulative probability distribution function (CDF) of Y is:

F(y) = {

        0,                             y < 0

        10*(1 - (1-y)^3 - 3(1-y)^4/4), 0 <= y <= 1

The probability of drawing a pair when selecting three cards at random from a standard 52-card deck is approximately 0.1694, or about 16.94%.

To calculate the probability of drawing a pair of cards from a standard 52-card deck when selecting three cards at random, we need to consider the number of favorable outcomes (pairs) and the total number of possible outcomes.

First, let's determine the number of favorable outcomes. For a pair, we need two cards of the same rank (e.g., two 7s, two Queens, etc.) and any third card that is different from the pair.

The number of ways to choose a rank for the pair is 13 (one for each rank). For each rank, there are four cards of that rank in the deck. Therefore, the number of ways to select two cards of the same rank is given by:

Number of ways to choose a pair = 13 * (4 choose 2) = 13 * 6 = 78

After selecting the pair, there are 50 cards remaining in the deck. The third card must be of a different rank from the pair. There are 48 cards remaining with different ranks from the pair.

Therefore, the number of favorable outcomes (pairs) is 78 * 48 = 3,744.

Next, let's calculate the total number of possible outcomes when selecting three cards from a standard deck. The total number of ways to choose any three cards from 52 cards is given by:

Total number of possible outcomes = (52 choose 3) = 22,100

Finally, we can calculate the probability of drawing a pair:

Probability of drawing a pair = Number of favorable outcomes / Total number of possible outcomes

= 3,744 / 22,100

≈ 0.1694

Therefore, the probability of drawing a pair when selecting three cards at random from a standard 52-card deck is approximately 0.1694, or about 16.94%.

For Jan, The total income is $2400

For Feb, the total income is $2700

For match , the total income is $3800

The total income is your gross income from all sources less certain deductions, such as expenses, allowances and reliefs.

Linda have 5% commission on first $10,000 and 10% on over $10,000 with a constant salary of $2000.

In January, she has a sales of $8000

therefore,

5/100 × 8000 = $400 commission.

Therefore her total income for January = 2000+400= $2400

In February, she has a sales of 12,000

10/100 × 2000 = $200

total commission = 500+200 = $700

therefore her total income for mach = $2000+$700 = $2700

In march, she has a sales of $23000

5/100 × 10000 = $500

10/100 × 13000 = $1300

her total commission = 1300+500 = $1800

therefore her total income for march = 1800+2000 = $3800.

Answer:

Circumference.

Step-by-step explanation:

The distance around a circle is its circumference.

The distance around a circular region is known as its CIRCUMFERENCE.

Answer:

x = 8 - 3y - 2z

Step-by-step explanation:

Step-by-step explanation:

x + 3y + 2z = 8

3x + y + 3z = -10

-2x - 2y - z = 10

we solve this by eliminating variables or expressing sine variables by others, and then solve for the remaining one. with that value we then cancer back to solve for the other variables.

in our case the easiest way is the elimination via combinations of equations.

let's first multiply equating 1 by -3 and then add that to equation 2 :

-3x - 9y - 6z = -24

3x + y + 3z = -10

----------------------------

0 - 8y - 3z = -34

8y + 3z = 34

then multiply equation 1 by 2 and add it to equation 3 :

2x + 6y + 4z = 16

-2x - 2y - z = 10

--------------------------

0 4y + 3z = 26

now we subtract this result from the previous result :

8y + 3z = 34

- 4y + 3z = 26

----------------------------

4y 0 = 8

y = 8/4 = 2

4×2 + 3z = 26

3z = 18

z = 18/3 = 6

x + 3×2 + 2×6 = 8

x = -10

so,

x = -10

y = 2

z = 6

Answer:

y = x + 5

Step-by-step explanation:

Perpendicular lines have opposite reciprocal slopes, so the line will have a slope of 1.

Then, plug in the slope and given point into y = mx + b to solve for b:

y = mx + b

-4 = 1(-9) + b

-4 = -9 + b

5 = b

Plug in the slope and b into y = mx + b:

y = 1x + 5

y = x + 5

So, the equation of the line is y = x + 5

The sides of the squares be to obtain a box with the largest volume is 114.20 inch³.

Quadratic functions are used in various fields of engineering and science to obtain the values ​​of various parameters. Graphically, they are represented by parabolas. Determines the direction of the curve based on the highest order coefficient. The word "quadratic" is derived from the word "Quad", which means square. In other words, a quadratic function is a "polynomial function of degree 2.

According to the Question:

Let a be the size of the square to be cut at 4 corners.

The cardboard is folded along the dotted line such that following are the box dimensions

Given that

Length, L= 11.5–2a ; Width. B = 8–2a ; Height, H = a

Volume of box, V = (18–2a )(8–2a) a

  V = (11.5-2a)(8-2a)a

⇒ V = 92a -3a²-16+ 4a³

⇒ V = 4a³-3a² +92a -16

Now,

The condition for volume to be maximum is that,

dV/da = 0

⇒ \(\frac{dv}{da} (4a^3)- \frac{dv}{da} (3a^2) +\frac{dv}{da}(92a) - \frac{dv}{da} (16)\)

⇒ 12a² -6a + 92

Taking common 2 from the above equation, we get:

⇒ 6a² - 3a + 46

Therefore,

The roots of this quadratic equation are,

a = 6.93 and 1.729

Case 1: If a = 6.93,

then B= -5.87 < 0  which is not a valid dimension.

Case 2: If a =1.729 then,

L = 14.54 ; B= 4.54 ; H=1.729

Therefore,

Volume of the box = 14.54 x 4.54 x 1.729 = 114.20

Therefore, the sides of the squares be to obtain a box with the largest volume is 114.20 inch³

To write each relation as a set of ordered pairs, we simply list out all the pairs included in each relation.  ROR (R composed with its inverse): This is the set of all pairs (x, y) such that there exists some z for which (x, z) is in R and (z, y) is in R's inverse (i.e. the set of all pairs in R with the elements swapped). We can write ROR as:
{(a, a), (b, b), (c, c), (d, d), (c, b), (b, c), (a, d), (d, a)}


For relation S:
- SOR (S composed with its inverse): This is the set of all pairs (x, y) such that there exists some z for which (x, z) is in S and (z, y) is in S. Since the inverse of S is just the set of all pairs in S with the elements swapped, we can write SOR as:
{(a, a), (b, b), (c, c), (d, d), (b, a), (c, a), (d, c), (a, c)}
- ROS (the inverse of S composed with R): This is the set of all pairs (x, y) such that there exists some z for which (z, x) is in the inverse of S and (z, y) is in R. The inverse of S is:
{(b, a), (c, a), (d, c), (a, c)}
So we need to find all pairs (x, y) such that there exists some z for which (z, x) is in this inverse and (z, y) is in R. This gives us:
{(a, c), (c, b), (d, b)}
- ROR (R composed with its inverse): This is the set of all pairs (x, y) such that there exists some z for which (x, z) is in R and (z, y) is in R's inverse (i.e. the set of all pairs in R with the elements swapped). We can write ROR as:

The mountain in "The Negro Artist and the Racial Mountain" is considered as an obstacle for Negro artists who wish for others to recognize their work. This isn't just part of their job, but it's part of a racial dispute because of their color. Langston Hughes, the author, describes these Negro artists as very talented people. These are also people who believe they can make it big as artists, but they wish to be white to do so. Black artists think they can't be accepted as people, let alone artists. So the mountain in the essay represents a huge obstacle these people have to achieve. That obstacle is being accepted by everyone else, and that includes them looking past their color before appreciating their art.
