The fiftieth termof the arithmetic sequence is 194.

Let the first term of the arithmetic

sequence

be 'a' and the common difference be 'd'.

Then the second term is 'a + d', the ninth term is 'a + 8d' and the fiftieth term is 'a + 49d'.

From the problem statement, we can form two equations:

a + d = 2 ...(1)

a + 8d = 30 ...(2)

Subtracting equation (1) from equation (2), we get:

7d = 28

d = 4

Therefore, the common difference of the arithmetic sequence is 4.

Substituting the

value

of d in equation (1), we get:

a + 4 = 2a

= -2

Therefore, the first term of the arithmetic sequence is -2.

The fiftieth term is given by:

a + 49d

= -2 + 49(4)

= -2 + 196

= 194

Therefore, the fiftieth term of the

arithmetic

sequence is 194.

The probability that at least one of the 5 systems will detect the theft when it occurs is what the bank is interested in. To find this probability, we can use the complement rule, which states that the probability of an event occurring is equal to 1 minus the probability of the event not occurring.

Let A be the event that at least one of the 5 alarm systems detects the theft. The complement of A is the event that none of the 5 systems detects the theft, which we will denote by A'.Since each system detects the theft with a probability of 0.88, the probability that any one system does not detect the theft is 1 - 0.88 = 0.12.

Therefore, the probability that none of the 5 systems detect the theft is: P(A') = (0.12)⁵ = 0.00005376Using the complement rule, we can find the probability that at least one of the 5 systems will detect the theft: P(A) = 1 - P(A') = 1 - 0.00005376 = 0.99994624Therefore, the probability that when a theft occurs, at least one of the 5 systems will detect it is approximately 0.99995 when rounded to 5 decimal places.

The statement is true. If two events are mutually exclusive, they have no outcomes in common. This means that the occurrence of one event excludes the possibility of the occurrence of the other event. In other words, both events cannot happen simultaneously.

For example, flipping a coin and rolling a die are mutually exclusive events because the outcome of one event does not affect the outcome of the other.
To further clarify, let's consider an example of two events that are not mutually exclusive. Let's say we are drawing a card from a deck of cards, and we are interested in two events: drawing a heart and drawing a face card. These two events are not mutually exclusive because there are face cards that are also hearts (e.g., King of Hearts). Therefore, the events have outcomes in common, and they can happen at the same time.
In summary, two events are mutually exclusive if they cannot happen at the same time and have no outcomes in common. It is an important concept in probability theory and is often used in calculating the probability of combined events.

The value of y is 67 degrees when line segment BD is parallel to XY.

A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.

The line segment BD is parallel to segment XY

We have to find the value of y

The angle 67 degrees and y are opposite to each other.

So the value of y is 67 degrees

The opposite angles are equal

The value of Y is 67 as angels that are opposite to each other are equal so the angle below Y is 67.

Knowing that we can say that Y is 67 as angels parallel to each other are also equal.

Hence, the value of y is 67 degrees when line segment BD is parallel to XY.

For each increase of one unit on the x-axis (the horizontal axis), the amount on the y-axis (the vertical axis) increases by the slope of the line.

Slope is the amount of change in the y-axis that occurs as a result of a one-unit change in the x-axis. It is also known as the rise over run.

A positive slope indicates that the line rises from left to right, while a negative slope indicates that the line falls from left to right. If the slope is zero, the line is horizontal.

The slope of a horizontal line is zero, and the slope of a vertical line is undefined because the x or y coordinate does not change as the other changes.

Therefore, the slope of a line represents the amount by which the value on the y-axis increases for every increase of one unit on the x-axis

The chi-square goodness-of-fit test can provide information on categorical data match an expected distribution and which categories are contributing to any deviation from that distribution.

The chi-square goodness-of-fit test is a statistical test used to determine whether a set of observed categorical data matches an expected distribution. Specifically, the test compares the observed frequencies of each category to the expected frequencies based on a hypothesized distribution, and calculates a chi-square statistic. This statistic measures the degree of difference between the observed and expected frequencies, with larger values indicating greater deviation from the expected distribution. If the chi-square statistic is large enough to reject the null hypothesis (i.e., the observed data do not match the expected distribution), the test can provide information on which categories are contributing the most to the discrepancy. This can help identify which categories are over-represented or under-represented in the observed data, and can inform further investigation into potential causes of the deviation. In summary, the chi-square goodness-of-fit test can provide information on whether observed categorical data match an expected distribution and which categories are contributing to any deviation from that distribution.

Answers: Options A and D

Answer:

A. The slope of m is -2/5

and

D. The slope of p is -5/2

Step-by-step explanation:

The slope is defined as the "change in y" over the "change in x" of a line. If you pick two points on a line --- (x1,y1) and (x2,y2) --- you can calculate the slope by dividing y2 - y1 over x2 - x1.

Line m goes through the points (-2,7) and (3,5). Slope = (y2 - y1)/(x2 - x1) = (5 - 7 )/(3 - -2) = -2/5

Line q goes through the points (6,15) and (0,0). Slope = (y2 - y1)/(x2 - x1) = (0 - 15 )/(0 - 6) = -15/-6 = 2.5 = 2 1/2 = 5/2

Line n goes through the points (-5,0) and (0,-2). Slope = (y2 - y1)/(x2 - x1) = (-2 - 0 )/(0 - -5) = -2/5

Line p goes through the points (6,15) and (10,5). Slope = (y2 - y1)/(x2 - x1) = (5 - 15 )/(10 - 6) = -10/4 = -2.5 = -2 1/2 = -5/2

The domain of the function f is {a, 6, c, d}, and the range of the function f is {2, 3, 4, 5}. The function f(b) is not defined because b is not in the domain of the function. However, f(d) is 5.

In this case, the domain of the function f is determined by the elements in the set A, which are {a, b, c, d}. In this case, the range of the function f is determined by the second elements in each ordered pair of the function f, which are {2, 3, 4, 5}.

Since the element b is not included in the domain of the function f, f(b) is not defined. It means there is no corresponding output value for the input b in the function f.
