Answer:

Step-by-step explanation:

x = 1 + 3i

x^2 = (1 + 3i)(1 + 3i)

x^2 = 1 + 6i - 9 = -8 + 6i

By a similar method

y = (x - i)

y^2 = x^2 - 2i*x + i^2

y^2 = x^2 - 2ix - 1

y^2 = -8+6i - 2i(1 + 3i) -1

y^2 = -8+6i -2i - 6i - 1

y^2 = -8 - 2i - 1

y^2 = - 9 - 2i

x^2 - y^2 = -8 + 6i - (9 - 2i)

x^2 - y^2 = -8 + 6i - 9 + 2i

x^2 - y^2 = -17 + 8i

Surface area of old cube

Side of new cube

Surface area

Difference

Answer:

A)  6(x + y)² = 6x² + 12xy +6y²

B)  12xy +6y²

Step-by-step explanation:

Surface area of a cube = 6s²  (where s is the side length)

Part A

Given:

⇒ Surface area of the original cube = 6x²

If the side length of the cube is increased by y, then:

⇒ Surface area of the new cube = 6(x + y)²

Expand and simplify:

⇒ 6(x + y)²

⇒ 6(x + y)(x + y)

⇒ 6(x² + xy + xy + y²)

⇒ 6x² + 12xy +6y²

Part B

To find the difference between the surface areas of the new and original cubes, subtract the surface area of the original cube from the surface area of the new cube:

⇒ SA of new cube - SA of original cube

⇒ 6x² + 12xy +6y² - 6x²

⇒ 12xy +6y²

Using the concept of percentage and fraction, the number of votes casted is 164160 which is fewer than the registered voters

Percentage is a way of expressing a number as a fraction of 100. It is often denoted using the percent sign, "%", or the abbreviation "pct." For example, 45% (read as "forty-five percent") is equal to 45/100, or 0.45.

In this question, we have to find 60 percent of 273600 and determine the value which is most likely fewer than the initial number of votes cast.

This can be calculated as;

60 / 100 = x / 273600

0.6 = x / 273600

Cross multiply both sides and solve for x

x = 273600 * 0.6

x = 164160

The probability is greater than 5%, it is not unlikely to obtain more than adults with blood type p(>4) =0.1402=14.02% and hence the result is not surprising.

In statistics, probability is the ratio of a number of possibilities in an entire sample of equal progression that produce a specific occurrence to the entire number of alternative possibilities.

Given  that n=7 p=0.44, we can use the binomial probability

\(P (X=k)= \left \ {n} \atop {k}} \right. * p^k* (1-p)^n^-^k\left\)

P(X=5)=\(\left \ {7} \atop {5}} \right. *(0.44)^5*(0.66)^7^-^5\) ≈ 0.10861

P(X=6)= \(\left \ {7} \atop {6}} \right. *(0.44)^6*(0.66)^7^-^6\) ≈ 0.0284

P(X=7)= \(\left \ {7} \atop {7}} \right. *(0.44)^7*(0.66)^7^-^7\) ≈ 0.00321

P(X>4= P(X=5) + P(X=6)+ P(X=7)

Answer:

Part A: \(l = 60\), Part B: \(b = \frac{9\sqrt{2}}{2}\)

Step-by-step explanation:

The Pythagorean Theorem determines the length of the hypotenuse of right triangle (\(r\)) by means of following formula:

\(r^{2} = x^{2}+y^{2}\) (1)

Where \(x\), \(y\) are respective lengths of each leg.

Now we proceed to solve on each triangle:

Part A: (\(r = l\), \(x = y = 30\sqrt{2}\))

\(l^{2} = (30\sqrt{2})^{2}+(30\sqrt{2})^{2}\)

\(l^{2} = 3600\)

\(l = 60\)

Part B: (\(r = 9\), \(x = b\), \(y = \frac{9\sqrt{2}}{2}\))

\(9^{2} = b^{2}+\left(\frac{9\sqrt{2}}{2} \right)^{2}\)

\(81 = b^{2}+\frac{81}{2}\)

\(b^{2} = \frac{81}{2}\)

\(b = \frac{9\sqrt{2}}{2}\)

The distribution is positively skewed or right-skewed.

From the given information, we can infer that the distribution of the dollar amounts for wedding gifts is skewed to the right or positively skewed.

The mean ($174) is smaller than the median ($205), indicating that the distribution is not symmetric. In a symmetric distribution, the mean and median would be approximately equal.

Since most of the dollar amounts were on the larger side and only a few dollar amounts were on the smaller side, this suggests that the majority of respondents were willing to spend higher amounts on wedding gifts. As a result, the tail of the distribution extends towards the larger values, causing the distribution to be skewed to the right.

Therefore, the distribution is positively skewed or right-skewed.

Given that a magnifying glass with a focal length of +4 cm is placed 3 cm above a page of print.

The distance from the lens to the image of the page is 12 cm, and the magnification of the image is -4.

We have to find out the distance from the lens to the image of the page and the magnification of the image.

(a) The distance from the lens to the image of the page:

As we know that the lens formula is `1/f = 1/v - 1/u` where;

f = focal length of the lens

v = distance of image from the lens

u = distance of object from the lens.

For a converging lens, the value of 'f' is taken as a positive (+) quantity.

Substituting the given values, we have;

f = +4 cm

v = ?

u = 3 cm

Hence, we have to find out the distance from the lens to the image of the page using the lens formula;\(1/4 = 1/v - 1/3= > 3v - 4v = -12= > v = +12/-1= > v = -12 cm\)

The negative value of 'v' indicates that the image is formed on the same side of the lens as the object.

The distance from the lens to the image of the page is 12 cm.

(b) The magnification of the image: Magnification (m) is defined as the ratio of the height of the image (h') to the height of the object (h);

m = h'/h

We know that the formula of magnification is;

m = v/u

Substituting the given values, we get;

m = -12/3

= -4T

he magnification of the image is -4.

This indicates that the image is virtual, erect, and 4 times the size of the object.

As a result, the distance from the lens to the image of the page is 12 cm, and the magnification of the image is -4.

The magnifying glass forms a magnified, virtual, and erect image of the object at a position beyond its focal length.

The magnification of the image produced is directly proportional to the ratio of the focal length of the lens to the distance between the lens and the object.

The correct interpretation for a 95% confidence interval is (c) 95% of the confidence intervals created around sample means will contain the population mean.

The confidence interval is a range of values that has been set up to estimate the value of an unknown parameter, such as the mean or the standard deviation, from the sample data. Confidence intervals are usually expressed as a percentage, indicating the probability of the actual population parameter falling within the given interval. Therefore, a 95% confidence interval, for example, indicates that we are 95% confident that the population parameter lies within the interval range.

The following interpretations for a 95% confidence interval are accurate:(a) The population mean will fall in a given confidence interval 95% of the time. This interpretation is incorrect because the population parameter is fixed, and it either falls within the confidence interval or it does not. Therefore, it is incorrect to say that it will fall within the interval 95% of the time.

To prove the opposite, we need to show that if G is not a pseudorandom generator (PRG), then Construction 3.17 cannot be EAV-secure.

Assume that G is not a PRG, which means it fails to expand the seed sufficiently. Let's suppose that G is computationally indistinguishable from a truly random function on its domain, but it does not meet the requirements of a PRG.

Now, consider the private-key encryption scheme Π described in Construction 3.17 using G as the pseudorandom generator. If G is not a PRG, it means that its output is not sufficiently pseudorandom and can potentially be distinguished from a random string.

Given this scenario, an adversary A could exploit the distinguishability of G's output and devise an attack to break the security of the encryption scheme Π. The adversary could potentially gain information about the plaintext by analyzing the ciphertext and the output of G.

Therefore, if G is not a PRG, it implies that Construction 3.17 cannot provide EAV-security, as it would be vulnerable to attacks by distinguishing the output of G from random strings. This contradicts Theorem 3.18, which states that if G is a PRG, then Construction 3.17 achieves indistinguishable encryptions.

Hence, by proving the opposite, we conclude that if G is not a PRG, then Construction 3.17 cannot be EAV-secure.
