Answer:

an = 2n + 10

Step-by-step explanation:

use formula an = a+( n -1)d

where , a = first term

n = number of terms

d = common difference

Here , a = 12 , let's suppose n = N and d = 14-12=2

so, an = 12 + ( N -1)2

an = 12+2N - 2

an = 2N +10

an = 2(N+5) is the equation for the nth term of arithmetic sequence of 12 , 14 , 16, 18-------

Geometric construction is the process of drawing a geometrical figure using two geometrical instruments, a compass, and a ruler.

Construction of an inscribed regular hexagon

1) Set compass width to the radius of the circle

2) Make an arc on the circle with the set radius.

3) From the previous arc draw another arc with the same radius.

4) Continue this process for the other vertex.

5) Connect all the vertices.

The MAD of 42 calories indicates calorie values of the sandwiches deviate from the mean by 42 calories.

A mean means the average of a data set found by adding all numbers together and then dividing the sum of the numbers by the number of numbers.

Mean = Ef/n

Mean = (242 + 290 + 290 + 280 + 390 + 350) / 6

Mean = 1842 / 6

Mean = 307 calories

The mean absolute deviation represents the average amount of deviation or variation of the data points from the mean.

The absolute deviations from the mean:

|242 - 307| = 65

|290 - 307| = 17

|290 - 307| = 17

|280 - 307| = 27

|390 - 307| = 83

|350 - 307| = 43

The mean absolute deviation (MAD) is:

= (65 + 17 + 17 + 27 + 83 + 43) / 6

A bar chart or box plot would be the most appropriate graphical representation to display the given data. The correct option is A.

The best graphical representation to display the given data would be a bar chart, also known as a bar graph.

A bar chart is a graph that represents categorical data with rectangular bars, where the height or length of each bar corresponds to the frequency or relative frequency of the category. In this case, the categories are the types of items purchased (Health & Medicine, Beauty, Household, and Grocery), and the frequency is the number of purchases in each category.

A box plot would not be appropriate for this data because it is not numerical data and cannot be separated into quartiles or percentiles. A line plot would also not be appropriate because it is used to display individual data points rather than grouped data.

A histogram would not be appropriate because it is used to display continuous numerical data rather than categorical data. A stem-and-leaf plot would not be appropriate because it is also used to display numerical data.

Therefore, a bar chart would be the most appropriate graphical representation to display the given data.

The approximate probability that all four seniors will be chosen at random is 0.48%.

To calculate the approximate probability that all four seniors will be chosen at random out of four seniors and six juniors competing for four places on a quiz bowl team, we need to consider the total number of ways to choose four students out of the ten, as well as the specific number of ways to choose all four seniors.

The total number of ways to choose four students out of the ten is given by the combination formula:

C(n, r) = n! / (r!(n - r)!)

Where n is the total number of students (10 in this case) and r is the number of students to be chosen (4 in this case).

So, the total number of ways to choose four students out of ten is:

C(10, 4) = 10! / (4!(10 - 4)!) = 210

Now, we need to determine the number of ways to choose all four seniors out of the four available senior spots. Since we are choosing all four seniors, there is only one way to do so.

Therefore, the probability of choosing all four seniors is:

Probability = (Number of ways to choose all four seniors) / (Total number of ways to choose four students)

Probability = 1 / 210

Approximately, the probability is 0.0048 or 0.48%.

Step-by-step explanation:

To find a degree 3 polynomial equation, q(x), with real coefficients, such that q(0)=6.08 and the zeros of the polynomial are 4 and 2i, we can use the fact that complex zeros occur in conjugate pairs.

The polynomial equation can be expressed as q(x)=a(x−4)(x−2i)(x+2i), where a is a constant.

We are given that the zeros of the polynomial are 4 and 2i. Complex zeros always occur in conjugate pairs, so the conjugate of 2i is -2i. Therefore, the polynomial equation can be written as

q(x)=a(x−4)(x−2i)(x+2i), where

a is a constant that we need to determine.

To find the value of a, we can use the fact that

q(0)=6.08.

Substituting x=0 into the equation, we get

q(0)=a(0−4)(0−2i)(0+2i)=a(−4)(−2i)(2i)=−16a.

Setting this equal to 6.08, we have -16a = 6.08.

Solving for a, we find

a=−6.08/16=−0.38.

Therefore, the polynomial equation with the desired properties is q(x)=−0.38(x−4)(x−2i)(x+2i), where the coefficients are all real.

The correct question would be: Find a degree 3 polynomial equation, q(x), with real coefficients, such that q(0)=6.08 and the zeros of the polynomial are 4 and 2i.

There probability 6C3 = 20 ways to select 3 items from a group of 6 items.

When selecting three items from a group of six items, the total number of combinations is referred to as a combination. Combinations are based on the concept of permutations, which is the number of ways an item can be rearranged. In this case, the number of permutations is 6P3 = 6 / (6 - 3) = 6 * 5 * 4 / 3 * 2 * 1 = 20. This means that there are 20 different combinations of three items that can be selected from the group of six items. To calculate the number of combinations, the formula 6C3 = 6 / (6 - 3) * 3 is used. This formula simplifies to 6 * 5 * 4 / 3 * 2 * 1, which equals 20.

The value of "a" is approximately 1.83 given that the absolute value of the difference of the two roots of the quadratic equation "ax squared plus 5x minus 3 equals 0" is the square root of 61 divided by 3, and "a" is positive.

We are given that the absolute value of the difference between the two roots of the quadratic equation "ax squared plus 5x minus 3 equals 0" is the square root of 61 divided by 3, and "a" is positive. We need to find the value of "a".

Let the two roots of the equation be r1 and r2, where r1 is not equal to r2. Then, we have:

|r1 - r2| = √(61) / 3

The sum of the roots of the quadratic equation is given by r1 + r2 = -5 / a, and the product of the roots is given by r1 × r2 = -3 / a.

We can express the difference between the roots in terms of the sum and product of the roots as follows:

r1 - r2 = √((r1 + r2)² - 4r1r2)

Substituting the expressions we obtained earlier, we have:

r1 - r2 = √(((-5 / a)²) + (4 × (3 / a)))

Simplifying, we get:

r1 - r2 = √((25 / a²) + (12 / a))

Taking the absolute value of both sides, we get:

|r1 - r2| = √((25 / a²) + (12 / a))

Comparing this with the given expression |r1 - r2| = √(61) / 3, we get:

√((25 / a²) + (12 / a)) = √(61) / 3

Squaring both sides and simplifying, we get:

25 / a² + 12 / a - 61 / 9 = 0

Multiplying both sides by 9a², we get:

225 + 108a - 61a² = 0

Solving this quadratic equation for "a", we get:

a = (108 + √(108² + 4 × 61 × 225)) / (2 × 61)

Since "a" must be positive, we take the positive root:

a = (108 + √(108² + 4 × 61 × 225)) / (2 × 61) ≈ 1.83

Therefore, the value of "a" is approximately 1.83.
