a. A central angle is: angle GFH; b. A major arc is: arc GJH; c. A minor arc is: arc GH.

d. measure of arc GJH = 265°; e. measure of angle GH = 95°

A major arc is an arc of a circle that measures greater than or equal to 180 degrees. It is sometimes called a large arc or a wide arc. If a circle has a central angle that measures more than 180 degrees, then the corresponding arc is a major arc.

On the other hand, a minor arc is an arc of a circle that measures less than 180 degrees. It is also called a small arc or a narrow arc. If a circle has a central angle that measures less than 180 degrees, then the corresponding arc is a minor arc.

Using the information given, we have:

a. A central angle in the figure given is: angle GFH.

b. A major arc in the figure given is: arc GJH.

c. A minor arc in the figure given is: arc GH.

d. measure of arc GJH = 360 - measure of arc GH

Measure of arc GH = measure of angle GFH = 95°

Therefore:

measure of arc GJH = 360 - 95 = 265°.

e. measure of angle GH = 95°

A 50 percent increase in Earth's albedo, which refers to the reflectivity of its surface, would lead to a decrease in average surface temperatures.

Albedo plays a crucial role in determining how much of the sun's energy is absorbed or reflected by the Earth. The given information states that approximately 30 percent of the sun's energy is currently reflected back into space. If Earth's albedo increases by 50 percent, meaning more energy is reflected, it would result in less energy being absorbed by the Earth's surface and atmosphere.

The increased albedo would cause a higher percentage of the incoming solar radiation to be reflected and scattered back into space. With less energy being absorbed, the average surface temperatures would decrease. This is because less solar energy would be available to warm the Earth's surface and drive atmospheric processes that contribute to temperature regulation. Therefore, a 50 percent increase in Earth's albedo would likely lead to a cooling effect and lower average surface temperatures on our planet.

A major disadvantage of electron microscopes compared to light microscopes is that they cannot be used to view live specimens. Therefore, option B is the correct answer.

A major disadvantage of electron microscopes compared to light microscopes is that they cannot be used to view live specimens. This is because the electron microscope requires a vacuum environment to function properly, which would kill any live specimen. Additionally, electron microscopes can only see surface details and do not have a very high power of resolution. Lastly, electron microscopes can only be used by doctors or trained technicians, so they are not as widely available as light microscopes.

Therefore, option B is the correct answer.

Question i: To express mlog_(z)n+5=q in exponential form, we need to rewrite it using exponentiation. In logarithmic form, the base (z), exponent (n+5), and result (q) are given. The exponential form will have the base (z), exponent (unknown), and result (m). Therefore, the exponential form would be:

z^(n+5) = m

Question ii: To solve the equation 2^(3x+1) = (1/4)^(x-5), we can rewrite both sides with the same base and equate the exponents:

2^(3x+1) = (2^(-2))^(x-5)

Using the property of exponentiation (a^(bc) = (a^b)^c), we simplify the equation to:

2^(3x+1) = 2^(-2(x-5))

Since the bases are the same, we can equate the exponents:

3x + 1 = -2(x-5)

Solving for x:

3x + 1 = -2x + 10
5x = 9
x = 9/5

Therefore, the solution to the equation is x = 9/5.

The points jada score is 159.25.

Given that james scored 182 points while playing a video game and he scored 7 times as many points as jada scored.

Let x be the points scored by james and y be the points scored by jada.

The total points scored by james and jada is 182 points.

x+y=182    .....(1)

James scored 7 times many points as jada scored.

y=7x         .....(2)

So, there are two equations and two unkowns.

Firstly, we will substitute equation (2) in equation (1), we get

x+7x=182

8x=182

Divide both sides by 8, we get

8x/8=182/8

x=22.75

Further, we will substitute the value of x in equation (2), we get

y=7×22.75

y=159.25

Hence, the jada score 159.25 when james scored 182 points while playing a video game and ahe scored 7 times as many points as jada scored.

Hence, the answer is 5a + 4.

The density function of the sample means, Y, can be found using the central limit theorem. According to the central limit theorem, as the sample size increases, the distribution of the sample mean approaches a normal distribution.

With mean equal to the population means, µ, and variance equal to the population variance divided by the sample size, σ^2/n. Thus, the density function of Y = 1/n * ∑ (Yi) is given by:

f(y) = (1 / (σ * √(n)) ) * exp( - ((y - µ)^2) / (2 * (σ^2/n)) )

B) If σ^2 = 16 and n = 25, the variance of the sample mean is 16 / 25 = 0.64. Thus, the standard deviation of the sample mean is the square root of 0.64, which is approximately 0.8.

The probability that the sample mean, Y, takes on a value that is within one unit of the population mean, µ, is given by the cumulative density function of a normal distribution with a mean equal to µ and standard deviation equal to 0.8, evaluated at y = µ + 1 and y = µ - 1.

Using a standard normal table or a calculator with normal distribution functions, we can find that:

P(|Y - µ| ≤ 1) = P(µ - 1 < Y < µ + 1) = P(-1 < (Y - µ) / 0.8 < 1) = P(-1.25 < Z < 1.25)

Where Z is a standard normal random variable.

From a standard normal table or using a calculator with normal distribution functions, we find that P(-1.25 < Z < 1.25) = 0.8944.

C) If σ^2 = 16 and n = 36, the variance of the sample mean is 16 / 36 = 0.4444, and the standard deviation of the sample mean the square root of 0.4444, which is approximately 0.6667.

Similarly, if n = 64, the variance of the sample mean is 16 / 64 = 0.25, and the standard deviation of the sample mean the square root of 0.25, which is approximately 0.5.

And if n = 81, the variance of the sample mean is 16 / 81 = 0.1981, and the standard deviation of the sample mean the square root of 0.1981, which is approximately 0.44504.

In all three cases, the probability that the sample mean, Y, takes on a value within one unit of the population means, µ, can be found as described in part B. As the sample size increases, the variance of the sample mean decreases, and the standard deviation of the sample mean becomes smaller. This means that the sample is less variable, and the probability that it falls within one unit of the population mean increases.

An appropriate assignment of digits to carry out the simulation to estimate the number of packages that would need to be randomly selected in order to find a package that was not delivered on time when a shipping company claims that 95% of packages are delivered on time is

01 - 05 = Packages delivered not on time

06 - 100 = Packages delivered on time

Random numbers are numbers selected from a set of limited or unlimited numbers without a particular pattern for prediction. In this case the student can generate random numbers from a limited pool of digits from 1 to 100 using any random number generator like excel.

Given that 95% of packages are delivered on time. Based on this statement we can assign that 95% of these generated random numbers represent packages delivered on time, here that is 06 - 100.

Hence random numbers from 01 - 05, the 5% of generated random numbers represents the packages not delivered on time.

The number of cases that will accommodate the number of sheets needed is calculated by applying simple proportion method.

Dimension of the package of sheets = 216 mm x 279 mm x 45 mm

The dimension of the package of a case = 216 mm x 279 mm x 270 mm

The only thing that changes here is thickness (270 mm for a case).

if 500 sheets requires =  270 mm thickness case

7000 sheets will require = ?

? = (7000 x 270) / 500

? = 3,780  mm

total of 3,780 thickness cases
