A class had 30 pupils at the beginning of this school term, but now has 5 more pupils. What is the percent of increase?

Answers

Answer 1
The percent of increase would be 16.66
Answer 2
Answer: 16.67%

Explanation:

You need to learn how to calculate percent to be able to perform this type of problems by yourself.

Percent is the ratio of a quantity on base to 100 parts.

In this case the increase is 5 students of an initial group of 30, so you need to find the equivalent expression with a base of 100 instead of 30.   That is, you need to find the ratio with denominator 100 equivalent to the ratio 5/30:

  x         5
------ = ----
100      30

=> x = (5 / 30) * 100 = 16.67%.

Also, you should notice that calculatind the percent is done dividing the parts by the whole and multiplying by 100, i.e. (5 / 30) * 100, which is the same done above.

Find the exact length of the curve.x = y48 + 14y2, 1 ≤ y ≤ 2

Answers

The original question I assume was:
[tex]x=\frac{y^4}{8}+\frac{1}{4y^2},1\leq y\leq 2[/tex]
We'll use the formula for the arc length of a function which is the following:
[tex]L=\int ds\\ ds=\sqrt{1+\lef(\frac{dx}{dy} )^2}dy[/tex]
Now let's get the derivative of x:
[tex]\frac{dx}{dy}=\frac{4}{8}y^3-\frac{2}{4}\frac{1}{y^{3}}\\=\frac{1}{2}(y^3-\frac{1}{y^3})[/tex]
Alright now plug this into ds formula to get:
[tex]ds=\sqrt{1+\frac{1}{4}(y^3-\frac{1}{y^3})^2}[/tex]
Notice that:
[tex]1+\frac{1}{4}(y^3-\frac{1}{y^3})^2=1+\frac{1}{4}y^6-\frac{1}{2}+\frac{1}{4y^6}\\ =(\frac{1}{2}y^3+\frac{1}{2}y^{-3})^2 [/tex]
Now the integral will be more simple:
[tex]L=\int_1^2\sqrt{(\frac{1}{2}y^3+\frac{1}{2}y^{-3})^2}dy=\int_1^2\frac{1}{2}y^3+\frac{1}{2}y^{-3}dy\\=[\frac{1}{8}y^4-\frac{1}{4}y^{-2}]_2^1\\ =\frac{33}{16}[/tex]

Final answer:

The exact length of the curve x = y^48 + 14y^2, for 1 ≤ y ≤ 2, can be found by differentiating x with respect to y, substituting into the formula for arc length, and solving the integral from y=1 to y=2.

Explanation:

To solve this problem, we use the formula for the arc length of a curve given by a function in parametric form. This formula is L = ∫sqrt(1+(dx/dy)^2)dy, with integration done over the interval [1,2].

In this case, our function is given as x = y^48 + 14y^2. First, we differentiate x with respect to y to get dx/dy = 48y^47 + 28y. We then substitute this into the formula to get L = ∫sqrt(1+(48y^47 + 28y)^2)dy. To solve this integral, you can use a standard calculus method or a calculator with integral functions. Make sure to evaluate the definite integral from y=1 to y=2.

Part A: The area of a square is (25x2 − 10x + 1) square units. Determine the length of each side of the square by factoring the area expression completely. Show your work. (5 points) Part B: The area of a rectangle is (81x2 − 9y2) square units. Determine the dimensions of the rectangle by factoring the area expression completely. Show your work. (5 points)

Answers

Before getting started, let's look at notation. My guess is that by (25x2-10x+1) you mean "25 x squared plus 10x plus 1." Usually to show the exponent (x squared) we use  the ^ symbol so that means for Part A you are being asked to factor 25x^2 -10x + 1. We can also use a program like equation editor (part of Word) so that the expressions look like they would if you wrote then by hand in your notebook. I will do PART A using "^" and PART B using an editor that will make the notation look as it does in your notebook so you see both ways.

PART A:
As the expression given is the area of a square (and in a square the sides are all of equal length) when we factor (write as a product) this expression we should get two identical factors. If you remember how to distribute twice (teachers usually use the term F.O.I.L.) this question is asking you to go backwards...the expression is what you get when you "FOIL" so what were the two terms before?

25x^2 --> What can you multiply to get 25x^2? Since the terms have to be identical that's 5x. That is (5x)(5x) gives 25x^2.

Next we look at the last term (1) and think what can you multiply by itself to get 1? That's 1 as (1)(1)=1.

This means that the expression 25x^2 -10x + 1 = (5x+1)(5x+1) = (5x+1)^2.
The side of the square is 5x+1

PART B:
Here you are asked to factor [tex]81 x^{2} -9 y^{2} [/tex]. You might notice that [tex]81 x^{2}[/tex] is a perfect square. [tex]81 x^{2} =(9x)(9x)[/tex]. Similarly, [tex]9 y^{2} =(3y)(3y)[/tex]. We are dealing with the difference (notice the subtraction sign between the terms) of squares.

How do we factor the difference of squares? It is: (square root of first term + square root of second term)(square root of first term - square term of second). In symbols it is: [tex] a^{2} - b^{2} =(a+b)(a-b)[/tex].

In our case, we get [tex]81 x^{2} -9 y^{2} =(9x+3y)(9x-3y)[/tex].

If you forget or don't see that it is the difference of squares you can still figure it out by reasoning it out. What two terms give you the first when multiplied and what two terms give you the second?

The area of the larger square is 16 times larger than the area of the smaller square.

Explanation:

The area of the larger square is 16 times larger than the area of the smaller square.



To find the area of a square, you square the length of one side.



For example, if the smaller square has a side length of 4 inches, the area is 4 * 4 = 16 square inches. The larger square, with side length 8 inches, has an area of 8 * 8 = 64 square inches. Therefore, the area of the larger square is 64 / 16 = 4 times larger than the area of the smaller square.

NOTE:
To show that a parallelogram is a rectangle, we need to show that ONE of the interior angles is a right angle.
Therefore we need to find the angle between two adjacent sides.

To find two adjacent sides in a parallelogram with vertices in counter-clockwise, we need two sides with a common vertex, for example, 
AB+BC, or BC+CD, or CD+DA, or DA+AB.

Any two sides without a common vertex are opposite sides.

Write the equation of the line that passes through (–2, 1) and is perpendicular to the line 3x – 2y = 5.

Answers

To make the perpendicular line, it is convenient to swap the x- and y-coefficients and negate one, then offset the x- and y- by the point value:
.. 2(x +2) +3(y -1) = 0

This equation can now be put into any desired form. Based on the given equation, it looks like you would like "standard form."
.. 2x +3y = -1

To find the equation of a line that is perpendicular to the line 3x - 2y = 5 and passes through the point (-2, 1), we determine that the slope of the perpendicular line must be -2/3. Using the point-slope form, the equation of the desired line is y = (-2/3)x - (1/3).

Finding the Equation of a Perpendicular Line

To write the equation of a line that is perpendicular to another line, you first need to determine the slope of the original line. The given equation, 3x - 2y = 5, can be rewritten in slope-intercept form (y = mx + b) by solving for y:
3x - 2y = 5
=> -2y = -3x + 5
=> y = (3/2)x - (5/2)
The slope (m) of this line is 3/2. Perpendicular lines have slopes that are negative reciprocals of each other. Thus, the slope of the line perpendicular to the original line is -2/3.

To find the equation of the line passing through the point (-2, 1) with this slope, use the point-slope form of the equation:
y - y1 = m(x - x1)
=> y - 1 = (-2/3)(x + 2)
Simplifying, we have:

y - 1 = (-2/3)x - (4/3)
=> y = (-2/3)x - (4/3) + 1
=> y = (-2/3)x -(1/3)

This is the equation of the line that passes through (-2, 1) and is perpendicular to the line 3x - 2y = 5.

A) 110.0 degrees
B) 153.9 degrees
C) 26.1 degrees
D) 70.0 degrees

Answers

1. By the Law of Sines, you have:

 SinA/a=SinB/b=SinC/c

  2. You don't need the fraction SinC/c, so you can eliminate it. Then:

 SinA/a=SinB/b

 A=40°
 a=19
 B=m∠b
 b=13

 3. When you substitute this values into SinA/a=SinB/b, you obtain:

 SinA/a=SinB/b
 Sin(40°)/19=SinB/13
 SinB=13xSin(40°)/19
 m∠b=SinB^-1(13xSin(40°)/19)
 m∠b=26.1°

 Therefore, the answer is: 26.1 degrees.

adding and subtracting fractions with unlike denominators

Answers

You must first find a common denominator.
Change the fractions to the common denominator.
Then you add or subtract the fractions.
Finally, you may need to reduce the fraction.

Example 1:

Add

1/5 + 1/3

The least common denominator is 15.

Both denominators must become 15.

1/5 + 1/3 = 3/3 * 1/5 + 5/5 * 1/3 = 3/15 + 5/15 = 8/15

Example 2:

Subtract
3/8 - 1/3

The least common denominator is 24.

3/3 * 3/8 - 8/8 * 1/3 = 9/24 - 8/24 = 1/24

Both in addition and subtraction, you only add or subtract the numerators. The denominator of the answer is the common denominator.
To add or subtract different fractions you need to make both fractions have an L.C.D = lowest common denominator. You can find the LCD by multiplying the denominators of the fractions together. Once you have the LCD you can multiply each fraction by a ratio of one (example = 3/3 ratio = 1 ) to make the denominators equivalent. 

Example problem: 
2/3 + 4/5 = ?
The L.C.D is equal to 15 (from multiplying the denominators 3 and 5 together).
Now you can make the first fraction (2/3) have a denominator of 15 by multiplying it by a ratio of 1 (5/5).  For the second denominator (4/5) multiply it by a ratio of 1 as well (3/3). Now the fractions will be (2/3)(5/5) + (4/5)(3/3) =  10/15 + 12/15 

Because the fractions have the same denominator now you can now add them together and then simplify the fraction to its simplest form. 
10/15 + 12/15 = 22/15 (This fraction cannot be reduced further, it is the final answer)

Answer: 24.52%

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

Work Shown:

Convert the time 7:45, which represents 7 min 45 sec, to seconds only
7:45 = (7 min) + (45 sec)
7:45 = (7*60 sec) + (45 sec)
7:45 = (420 sec) + (45 sec)
7:45 = (420+45) sec
7:45 = 465 sec

Do the same for 5:51
5:51 = (5 min) + (51 sec)
5:51 = (5*60 sec) + (51 sec)
5:51 = (300 sec) + (51 sec)
5:51 = (300+51) sec
5:51 = 351 sec

So the initial time is 465 seconds and it drops to 351 seconds
Subtract the values to find the amount dropped: 465-351 = 114

Divide that difference over the initial time: 114/465 = 0.24516

Move the decimal over 2 spots to the right to convert to a percentage: 0.24516 --> 24.516%

Then round to the nearest hundredth of a percent (2 decimal places) to go from 24.516% to 24.52% which is our final answer

So the reduction is roughly 24.52%
This means if you took 24.52% of the initial time and subtracted it off, then you'd get to about 351 seconds.

By the empirical rule, 84% of the distribution is below one standard deviation above the mean.

16% of Ed's monthly phone bills are more than $76.

Answer:

16% of his phone bills are more than $76

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 65

Standard deviation = 11

What percentage of his phone bills are more than $76?

76 = 65 + 11

So 76 is one standard deviation above the mean.

By the Empirical Rule, 68% of the measures are within 1 standard deviation of the mean. The other 100-68 = 32% are more than 1 standard deviation from the mean. Since the normal probability distribution is symmetric, 16% of them are more than 1 standard deviation below the mean and 16% are more than 1 standard deviation above the mean. So

16% of his phone bills are more than $76

The transport layer handles the transmission error by requesting the damaged segments to be retransmitted. if the probability of a segment being damaged is p, what is the mean number of the transmissions required to send a segment? you can assume the acknowledgements are never lost for solving this question.

Answers

The geometric distribution applies to experiments employing Bernoulli trials (success or failure) to determine the number of trials to obtain the first success.
This distribution may be applied to the given situation, where the probability of success is p.
Let n=number of transmissions required  (n &ge; 1)Then
P(n)=(1-p)^(n-1)*p   (probability that n transmissions are required)
and the mean number of transmissions required
&mu; = 1/p

Final answer:

The mean number of transmissions required to send a segment successfully, given a damage probability of p, is calculated as 1/(1-p). This is derived from the geometrical distribution, representing the expected number of trials until the first success.

Explanation:

The question asks for the mean number of transmissions required to successfully send a segment given that the probability of a segment being damaged is p, and assuming acknowledgements are never lost. To solve this, we consider each transmission attempt as an independent trial with only two outcomes: success (with probability 1-p) or failure (with p). The problem thus resembles a geometrical distribution where the expected value (mean number of trials to get the first success) can be calculated as 1/(1-p). Therefore, if the probability of a segment being damaged is p, the mean number of transmissions required to send a segment successfully is 1/(1-p).

For example, if the probability of damage is 0.1 (p=0.1), then the mean number of transmissions would be 1/(1-0.1) = 1.1111, rounding up since you can't have a fraction of a transmission in reality.

Your brother is 13 your age. Your sister is 6 years older than your brother. Your sister is 10 years old. Write and solve an equation to find your age a.

Answers

By setting up equations using the information about your siblings' ages, we find out that you are 12 years old.

To find your age, we can set up an equation based on the information given:

Your sister is 10 years old.

Your brother is 13 your age, meaning 1/3 of your age.

Your sister is 6 years older than your brother. Therefore, if your brother's age is b, your sister's age is b + 6.

Since your sister is 10, this allows us to write the equation for your brother's age as:

b + 6 = 10

Solving for b, we get:

b = 10 - 6 => 4

Now we know your brother is 4 years old, and since he is 13 your age, we can write another equation:

a ÷3 = 4

Multiplying both sides by 3 to solve for a:

a = 4 × 3 => 12

You are 12 years old.

If value of b is lesser than 1 but greater than 0, then it is decay of population.

On comparison of the given equation with its general form, we get a = 10000, b = 0.97

So initial value is 10000.

Since value of b is 0.97 i.e. lesser than 1, so it is decay of population.

Hence, the given equation represents "Decay".

Second question: maybe but nothing is certain when you're talking about anything between men and women. This is not part of the answer. It's just an observation.

Figure this question out first as though you don't get any females. They are all males. The total number of ways that you can distribute 9 children by gender is 2^9 = 512
There is only one way that you can get all males and that is M M M M M M M M M  so the chances are 1 chance in 512 or 1/512 
All males = 0.001953

So the chances of there being at least 1 female is
1 - 1/512 = 0.998

Which contrary to my opening remark is almost certainty.
