Answer:

19.5 is the median

Step-by-step explanation:

count the amount of numbers presented and we have 6, the next decision differs on whether or not the amount is an even amount or odd, in this case it is an even number.  So divide your amount by 2 and we have 3.  Then count your first 3 numbers and on the third number you will need to find the average between the third and fourth number, so that would mean finding the number that is in the middle of these two numbers and we have 19.5.

Answer: 48s + 4.75

Step-by-step explanation:

Each scarf is sold for $48 which is why the total price of buying s scarves is 48s or 48*s.

Assuming a single order of scarves can contain more than one scarf then that means that for s scarves, the shipping fee will remain the same at $4.75.

Should this be the case then the expression for an order of scarves will be;

= 48s + 4.75

This shows the price of ordering s number of scarves plus the shipping cost of $4.75 for the order comprising s number of scarves.

Angles are a fundamental concept in geometry that is used in many different fields, including mathematics, engineering, and architecture. Despite their importance, it is not uncommon for students to struggle with angles, especially when they are first learning about them. If you are starting to hate angles, it may be helpful to take a step back and try to understand why you are struggling with them. Here are a few possible reasons why you might be feeling frustrated with angles:

- Lack of understanding: If you don't understand what angles are or how to measure them, it can be difficult to solve problems that involve them. Make sure you have a solid understanding of the basic concepts before moving on to more complex problems.
- Confusing terminology: There are many different terms associated with angles, such as acute, obtuse, complementary, and supplementary. If you are getting these terms mixed up, it can make solving problems more challenging. Take some time to review the different types of angles and their associated vocabulary.
- Difficulty visualizing angles: For some students, it can be difficult to visualize angles and how they relate to other shapes. Try using visual aids, such as diagrams or models, to help you understand how angles work.

If you are struggling with angles, remember that you are not alone. Many students find this topic challenging, but with practice and perseverance, you can improve your understanding and become more comfortable working with angles. Don't be afraid to ask your teacher or tutor for help if you are struggling, and remember to take breaks and give yourself time to rest when you need it. Good luck!

It is False that by adding the number of inner loops , we get the total number of iterations.

A loop is defined as a segment of code that executes multiple times. Iteration refers to the process in which the code segment is executed once. One iteration refers to 1-time execution of a loop. A loop can undergo many iterations.

There are 3 types of iteration: tail-recursion, while loops, and for loops. We will use the task of reversing a list as an example to illustrate how different forms of iteration are related to each other and to recursion. A recursive implementation of reverse is given below.

The ordered pair that is the best exact solution is (0.9, 1)

Substitution of variable is the act of replacing variable with exact values. for example for an equation of y = x² +2

The value of y for the values of x = 1,2,3,4 will be

y = 1² +2 = 3

y = 2² + 2 = 6

y = 3² + 2 = 11

y = 4² +2 = 18

Similarly l, for the equation y = -4x+3

when x is 0.9

The number of permutations of putting the 28 cards into the envelopes is 1024.

A permutation is the arrangement of objects in a specific order. When we are counting the number of permutations of a set of objects, we are finding the total number of ways that the objects can be arranged.

In your question, you have 28 cards and 10 envelopes. To find the number of permutations of putting the 28 cards into the envelopes, we need to consider a few factors.

Firstly, each envelope can only hold a maximum of

=> 28/10 = 2 cards.

Secondly, the order in which the cards are placed into the envelopes matters,

Since each envelope can only hold a maximum of 2 cards, we have two options for each envelope: either 0 cards or 2 cards.

We can use a binary code of 0 and 1 to represent this, where 0 means the envelope is empty and 1 means the envelope has 2 cards.

Therefore, the total number of permutations can be calculated as

=> 2¹⁰ = 1024

c. The number of clay beads and glass beads in a necklace that costs the least to make is: 4 clay beads and 4 glass beads.

The variables for the system are presented as follows:

Each necklace has no more than 10 clay beads and at least 4 glass beads, hence the constraints are listed as follows:

The numbers of each beads are countable amounts, meaning that they cannot assume negative values.

Four times the number of glass beads is less than or equal to 8 more than twice the number of clay beads, hence the final constraint is of:

4y ≤ 8 + 2x.

Each clay bead costs $0.20 and each glass bead costs $0.40, hence the cost function is given as follows:

C(x,y) = 0.2x + 0.4y.

Using the three constraints, the graph is given by the image at the end of the answer, and the vertices are as follows:

Answer: y <= -3x + 3

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

Explanation: The slope of the boundary line is -3 because we go down 3 over 1 each time we go from point to point. We can use the slope formula to get

m = (y2-y1)/(x2-x1)

m = (-3-3)/(2-0)

m = -6/2

m = -3

The y intercept is 3 because this is the location on the y axis where the graph crosses, so b = 3

Therefore the boundary line equation is y = -3x+3. Note how it's in the form y = mx+b where m = -3 and b = 3

The boundary line is solid. The shading is below the boundary line. So we change the equal sign to a "less than or equal to" sign to get the final answer of y <= -3x+3

Rounding a percentage to the nearest whole number can be done by considering the decimal part of the percentage. For the percentages provided, 11.969 would round to 12%, 39.9804 would round to 40%, and 11.61+32 would equal 43.

To round a percentage to the nearest whole number, we examine the decimal part. If the decimal is 0.5 or greater, we round up to the next whole number. If the decimal is less than 0.5, we round down to the previous whole number. In the given examples, 11.969 has a decimal of 0.969, which is closer to 1 than to 0, so it rounds up to 12. Similarly, 39.9804 has a decimal of 0.9804, which is closer to 1, resulting in rounding up to 40. Lastly, the expression 11.61 + 32 equals 43, as it is a straightforward addition calculation.

Answer:

There are 10 nickels and 11 quarters in the jar.

Step-by-step explanation:

Given that:

Total coins = 21

Total value = $3.25 = 3.25*100 = 325 cents

One nickel = 5 cents

One quarter = 25 cents

Let,

x be the number of nickels

y be the number of quarters

According to given statement;

x+y=21       Eqn 1

5x+25y=325    Eqn 2

Multiplying Eqn 1 by 5

5(x+y=21)

5x+5y=105     Eqn 3

Subtracting Eqn 3 from Eqn 2

(5x+25y)-(5x+5y)=325-105

5x+25y-5x-5y=220

20y=220

Dividing both sides by 20

\(\frac{20y}{20}=\frac{220}{20}\\y=11\)

Putting y=11 in Eqn 1

x+11=21

x=21-11

x=10

Hence,

There are 10 nickels and 11 quarters in the jar.

Answer:

Step-by-step explanation:

The value of cosec ( Ф/2 ) obtained using the double angles formula and half angle identity is : cosec ( Ф/2 ) = 5/√2.

In trigonometry, the double angles for trigonometric functions are dealt with via the double angle formulas. Other significant double angle formulas include:

cos Ф = 3/5

By using half angle identity:

cos( Ф/2 ) = ±  √(1 + cosФ)/2

cos( Ф/2 ) = ±  √(1 + 3/5)/2

cos( Ф/2 ) = ±  √8/10

cos( Ф/2 ) = ±  √2/5

In first quadrant:

cos( Ф/2 ) = +√2/5

Using reciprocal identity:

cosec ( Ф/2 ) = 1/ cos( Ф/2 )

cosec ( Ф/2 ) = 1/√2/5

cosec ( Ф/2 ) = 5/√2

Thus, the value of cosec ( Ф/2 ) obtained using the double angles formula and half angle identity is : cosec ( Ф/2 ) = 5/√2.
