In 1798, the first vaccination (for small pox) was discovered. The most notable achievement of these efforts has been the elimination of smallpox sickness from the world.

Hence, option (c) is correct choice.

In 1721, Lady Mary Wortley Montagu introduced smallpox vaccination to Europe by requesting that her two children be immunised against the disease, as she had seen done in Turkey. Dr. Edward Jenner developed the world's first effective vaccination. He discovered that those who had cowpox were resistant to smallpox.

Edward Jenner, a rural doctor from Berkeley (Gloucestershire), England, conducted the world's first vaccine in 1796. Jenner injected an eight-year-old kid, James Phipps, with pus from a cowpox lesion on a milkmaid's hand.

When conducting time series forecasting, it is not necessarily safest to utilize regression analysis. Regression analysis is a statistical method used to model the relationship between a dependent variable and one or more independent variables. However, it may not be the most appropriate technique for time series forecasting.

Time series forecasting involves analyzing and predicting patterns and trends in sequential data over time. Techniques specifically designed for time series analysis, such as ARIMA (Autoregressive Integrated Moving Average) models, exponential smoothing methods, or state space models, are generally more suitable for time series forecasting.

Regression analysis assumes that there is a linear relationship between variables, which may not hold in time series data where patterns can exhibit trends, seasonality, or other complex dynamics. Extrapolation, which involves extending a trend beyond the observed data range, can still occur in regression analysis if not properly accounted for.

Therefore, it is important to choose appropriate time series forecasting methods rather than relying solely on regression analysis to ensure accurate and reliable predictions.

The given function x(t) cannot be directly plotted due to the presence of unit step functions. The integral of x(t)δ(t - 2) dt is -2, obtained by evaluating x(t) at t = 2.

Plot the given function x(t) = 2(t - 1)[u(t + 1) - u(t)] - 2(t - 1)[u(t) - u(t - 1)], you can use the MATLAB `plot` function. However, since the function contains unit step functions, it is not continuous. Therefore, it cannot be plotted directly.

For the second part of the question, to find the integral ∫ x(t)δ(t - 2) dt, where δ(t - 2) is the Dirac delta function centered at t = 2, we can utilize the properties of the Dirac delta function.

The integral of x(t)δ(t - 2) dt can be found by evaluating x(t) at t = 2, which will give the value of x(t) at the location of the Dirac delta function.

Using the given function x(t), we substitute t = 2:

x(2) = 2(2 - 1)[u(2 + 1) - u(2)] - 2(2 - 1)[u(2) - u(2 - 1)]

Simplifying further:

x(2) = 2[u(3) - u(2)] - 2[u(2) - u(1)]

x(2) = 2[u(3) - 2u(2) + u(1)]

Since u(t) is a unit step function, u(t) = 1 for t ≥ 0 and u(t) = 0 for t < 0.

Evaluating x(2) using the unit step function properties:

x(2) = 2[1 - 2(1) + 0] = 2[1 - 2] = 2(-1) = -2

Therefore, the integral ∫ x(t)δ(t - 2) dt is equal to -2.

Answer:

A 13

Step-by-step explanation:

Add all the electoral votes together (266)

266 / 21 = 12.666 ~ 13

The median number of given electoral votes is equal to 15, as it is the value at the 5th position in the ordered data set.

To find the median number of electoral votes for the 21 states,

first need to arrange the data in ascending order:

Electoral votes: 10, 11, 12, 13, 15, 17, 20, 21, 27, 31, 34, 55

Frequency: 4, 4, 1, 1, 3, 1, 1, 2, 1, 1, 1, 1

Next, need to calculate the cumulative frequency (CF) by adding up the frequencies from the lowest electoral vote to the highest:

Cumulative frequency: 4, 8, 9, 10, 13, 14, 15, 17, 18, 19, 20, 21

The median is the middle value of the data set when it is arranged in ascending order.

Since we have 21 states, which is an odd number, the median will be the value at the 11th position (or 11/2 = 5.5th position).

To find the median, we look for the value at the 5th position (11/2 = 5.5):

Electoral votes: 10, 11, 12, 13, 15, 17, 20, 21, 27, 31, 34, 55

Position: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12

Mark has 5253 cups of sugar left after using 145 cups for a pie and 12/1 cups for his iced tea.

Mark has 5410 cups of sugar, and he used 145 cups for a pie and 12 of a cup in his iced tea. To find out how many cups of sugar he has left, we need to subtract the amount of sugar he used from the total amount of sugar he had:

Total amount of sugar = 5410 cups

Amount of sugar used for pie = 145 cups

Amount of sugar used for iced tea = 12/1 cups (since 12 of a cup is the same as 12/1 cups)

Total amount of sugar used = 145 cups + 12/1 cups = 157 cups

Amount of sugar left = Total amount of sugar - Total amount of sugar used

Amount of sugar left = 5410 cups - 157 cups

Amount of sugar left = 5253 cups

Therefore, Mark has 5253 cups of sugar left after using 145 cups for a pie and 12/1 cups for his iced tea.

Step-by-step explanation:

Answer:

$4.20 Per month = $4.2/1month

Step-by-step explanation:

1 year = 12 months

Proportions:

12 months ⇒ $48.24

1 month ⇒ $P

P = 48.24*1/12

P = $4.2

The probability that a student's score is less than 81 points on the reading ability test is 0.9772. We would expect approximately 489 students to earn a score less than 81 points if 500 students took the reading ability test. The probability of randomly selecting 35 students (all from the same class) that have a sample mean reading ability test score between 66 and 68 is approximately 0.2190.

To find the probability that a student's score is less than 81 points, we need to standardize the score using the z-score formula:

z = (x - μ) / σ

where x is the student's score, μ is the mean score, and σ is the standard deviation. Plugging in the values, we get:

z = (81 - 65) / 8 = 2.00

Using a standard normal distribution table or calculator, we can find the probability of a z-score less than 2.00 to be approximately 0.9772. Therefore, the probability that a student's score is less than 81 points is 0.9772.

Since the distribution is normal, we can use the normal distribution to estimate the number of students who would earn a score less than 81. We can standardize the score of 81 using the z-score formula as above and use the standardized score to find the area under the normal distribution curve. Specifically, the area under the curve to the left of the standardized score represents the proportion of students who scored less than 81. We can then multiply this proportion by the total number of students (500) to estimate the number of students who would score less than 81.

z = (81 - 65) / 8 = 2.00

P(z < 2.00) = 0.9772

Number of students with score < 81 = 0.9772 x 500 = 489

Therefore, we would expect approximately 489 students to earn a score less than 81 points.

The distribution of the sample mean reading ability test scores is also normal with mean μ = 65 and standard deviation σ / sqrt(n) = 8 / sqrt(35) ≈ 1.35, where n is the sample size (number of students in the sample). To find the probability that the sample mean score is between 66 and 68, we can standardize using the z-score formula:

z1 = (66 - 65) / (8 / sqrt(35)) ≈ 0.70

z2 = (68 - 65) / (8 / sqrt(35)) ≈ 2.08

Using a standard normal distribution table or calculator, we can find the probability that a z-score is between 0.70 and 2.08 to be approximately 0.2190. Therefore, the probability of randomly selecting 35 students (all from the same class) that have a sample mean reading ability test score between 66 and 68 is approximately 0.2190.

A common everyday counting unit that is used to mean 12 of an object is a Dozen

Dozen is derived from the Old French word "douzaine" which means twelve each. In most situations, a dozen is used to refer to a group of twelve items. The term dozen is also used in informal situations to refer to a very large number of objects. For example, one might say "I have dozens of friends!" to mean that they have a lot of friends.

Dozen is a useful term when counting items. It allows for large numbers to be easily broken down into manageable groups. For example, if you have 120 pencils, you could easily count them by saying that you have 10 dozen pencils. It can also be useful when talking about fractions. For example, instead of saying "one and a half of an item," one could say "one and a half dozen of an item."

Dozen is a common everyday counting unit that is used to mean 12 of an object. It is a useful term when counting items and when talking about fractions, and can be used in both formal and informal settings.

(2x + 2) × (4x - 1)  

collecting like terms: (2x, 4x) (2, -1)

(2x × 4x) (2 × (-1)) = 8x² - 2.

The above is the wrong way of expanding the bracket. The correct way of doing it is as follows:

(2x + 2) (4x - 1)

Each term in one bracket multiplies each term in the second bracket.
