Answers
The correct answer is d. More accurate and more reliable than a 90% CI. 95% confidence interval is less accurate and less reliable than a 99% confidence interval, which is incorrect.
When comparing confidence intervals, a higher confidence level indicates greater reliability, meaning there is a higher probability that the interval contains the true population parameter. A 95% confidence interval is more reliable than a 90% confidence interval because it provides a narrower range of values. Therefore, option b is incorrect.
Regarding accuracy, a narrower confidence interval indicates higher accuracy because it provides a more precise estimate of the population parameter. Since a 95% confidence interval is narrower than a 99% confidence interval, it is more accurate in capturing the true value of the parameter. Therefore, option a is incorrect.
Option c is also incorrect because it suggests that a 95% confidence interval is less accurate and less reliable than a 99% confidence interval, which is incorrect.
Thus, the correct answer is d. A 95% confidence interval is more accurate and more reliable than a 90% confidence interval.

mean absolute deviation (MAD):
Answers
The mean absolute deviation of the given data set is 1.6 (rounded to the nearest tenth).
We have,
In statistics, the mean (also known as the arithmetic mean or average) is a measure of central tendency that represents the sum of a set of numbers divided by the total number of numbers in the set.
To find the mean absolute deviation (MAD), we need to first calculate the mean of the given data set:
mean = (4 + 5 + 7 + 9 + 8) / 5 = 6.6
Next, we calculate the deviation of each data point from the mean:
|4 - 6.6| = 2.6
|5 - 6.6| = 1.6
|7 - 6.6| = 0.4
|9 - 6.6| = 2.4
|8 - 6.6| = 1.4
Then we find the average of these deviations, which gives us the mean absolute deviation:
MAD = (2.6 + 1.6 + 0.4 + 2.4 + 1.4) / 5 = 1.6
Therefore, the mean absolute deviation of the given data set is 1.6 (rounded to the nearest tenth).

Given: quadrilateral MATH; M(-5,-2), A(-3,2),
T(3,2) and H(1,-2)
Prove: MATH is a parallelogram
State the formula you will be using.
Show all work.
Answers
Answer:
MATH is not a parallelogram
Step-by-step explanation:
(sqrt means squareroot)
To prove that quadrilateral MATH is a parallelogram, we can use the following formula:
A quadrilateral is a parallelogram if and only if both pairs of opposite sides are congruent.
In other words, if the lengths of the sides opposite each other in a quadrilateral are the same, then the quadrilateral is a parallelogram.
To prove that MATH is a parallelogram, we need to show that both pairs of opposite sides are congruent.
The first pair of opposite sides consists of segment MA and segment TH. To show that these sides are congruent, we can use the Distance Formula:
d = sqrt((x2 - x1)^2 + (y2 - y1)^2)
Where (x1, y1) and (x2, y2) are the coordinates of the two points that define the line segment.
Substituting the coordinates of points M and A, we get:
d = sqrt((-3 - (-5))^2 + (2 - (-2))^2)
= sqrt((-3 + 5)^2 + (2 + 2)^2)
= sqrt(8^2 + 4^2)
= sqrt(64 + 16)
= sqrt(80)
= 8.944
Substituting the coordinates of points T and H, we get:
d = sqrt((1 - 3)^2 + (-2 - 2)^2)
= sqrt((-2)^2 + (-4)^2)
= sqrt(4 + 16)
= sqrt(20)
= 4.472
Since 8.944 is not equal to 4.472, we cannot conclude that MA and TH are congruent. Therefore, MATH is not a parallelogram.

Which of the following would be the positive x-coordinate where the line y = x+2 intersects the circle
x² + y² = 13?
Answers
Answer:
The answer is 1.35 answer (1). You can graph both equations to give you the answer.
Step-by-step explanation:
Graph the equations and see where they intersect.
The positive x coordinate is given as √13/2 - 1.
How to write the equation of a circle?The equation for a circle having the centre located at a point (a, b) and the radius r can be written as (x - a)² + (y - b)² = r².
Given that,
The equation for the line is y = x + 2
And, the equation of the circle is x² + y² = 13.
In order to find the point of intersection substitute the equation of line into that of circle as below,
x² + y² = 13
=> x² + (x + 2)² = 13
=> x² + x² + 4x + 4 = 13
=> 2x² + 4x - 9 = 0
Use quadratic formula to solve the above equation as,
x = (-4 ± √(4² - 4 × 1 × -9))/(2 × 2)
= -1 ± √13/2
Thus, the positive x coordinate is given as √13/2 - 1.
Hence, the positive x-coordinate of the point of intersection of the circle and line is given as √13/2 - 1.

Answers
x = 245/5 x = 49, the length of the side LN is 49 cm.
The sides of the triangles ABC and LMN are proportional due to their similarity. Let's call the length of the LN side x cm.
We are able to establish the proportion based on the similarity as follows:
When we plug in the given values, we get AB/LM = AC/LN:
5/35 = 7/x We can cross-multiply and solve for x to get x:
When we divide both sides by 5, we get: 5x = 7 * 35 5x = 245
Since x = 245/5 x = 49, the length of the side LN is 49 cm.
