What are reference angles according to quadrats?We have I, II, III, IV quadrants.In quadrant I the referece angle Ф is Ф.
In quadrant II the referece angle Ф is (π - Ф).
In quadrant III the referece angle Ф is (π + Ф).
In quadrant IV the referece angle Ф is (2π - Ф).
We know, cos is -ve on III and IV quadrants, and cot = 1/tan is +ve on I and III quadrant.
Therefore, The combined condition cos < 0 and cot > 0 satisfies on the II quadrant.

The time needed to complete a final examination in a particular college course is normally distributed with a mean of minutes and a standard deviation of minutes. Answer the following questions. a. What is the probability of completing the exam in one hour or less (to 4 decimals)? 0.0228 b. What is the probability that a student will complete the exam in more than minutes but less than minutes (to 4 decimals)? .2858 c. Assume that the class has students and that the examination period is minutes in length. How many students do you expect will be unable to complete the exam in the allotted time (to nearest whole number)?
Answer:
a. This probability is the p-value of Z when X = 60.
b. This probability is the p-value of Z when X = B subtracted by the p-value of Z when X = A.
c. The proportion is the p-value of Z when X is the length of the examination period. How many students is this proportion multiplied by the number of students.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
In this question:
Mean [tex]\mu[/tex], standard deviation [tex]\sigma[/tex].
a. What is the probability of completing the exam in one hour or less (to 4 decimals)?
This probability is the p-value of Z when X = 60.
b. What is the probability that a student will complete the exam in more than minutes A but less than B minutes (to 4 decimals)?
This probability is the p-value of Z when X = B subtracted by the p-value of Z when X = A.
c. Assume that the class has students and that the examination period is minutes in length. How many students do you expect will be unable to complete the exam in the allotted time (to nearest whole number)?
The proportion is the p-value of Z when X is the length of the examination period. How many students is this proportion multiplied by the number of students.

A sample of experienced typists revealed that their mean typing speed is 87 words per minute and the median typing speed is 73 words per minute. The standard deviation of typing speed is 16.9 words per minute. What is the Pearson coefficient of skewness
Answer:
The Pearson coefficient of skewness is of 0.8284.
Step-by-step explanation:
Pearson skewness:
The skewness of a data set is given by the subtraction of the mean by the median, divided by the standard deviation.
In this question:
The mean is of 87, the median is of 73 and the standard deviation is of 16.9. So
(87-73)/16.9 = 0.8284.
The Pearson coefficient of skewness is of 0.8284.

Which numbers are rational?
Select each number that is correct.
23.429
10
13
151
8/7
-4.93
Answer:
All of them.
Step-by-step explanation:
Rational numbers are defined as the numbers that can be expressed as the ratio of two integers(a/b) where b must be a non-zero number. The rational numbers display a terminating characteristic and they also contain repeating, as well as, recurring digits. All the given numbers are rational as they can be written in the form of p/q.
23.429 = It can be written as a fraction. So, it is a rational number.
10 = 10 is a whole number and it can be written in the form of a/b i.e. 10/1. So, it is a rational number.
13 = 13 also can be written in ration form as 13/1. Therefore, it is also a rational number.
151 = It can be written as 151/1. Hence, it is a rational number.
8/7 = It is already mentioned in the form of a/b. So, it is a rational number.
-4.93 = since it is an integer, it will surely be a rational number.
Maya wants to determine the area of a circle. She uses a compass and ruler to draw a circle that has a radius of r. She then inscribes a regular octagon within the circle, as shown above. The octagon is divided into 8 congruent triangles, and each of the 8 interior angles measure 45°.
She then labels the height and base of one of the triangles within the circle. She labels the height h, and the base, b.
She then makes three claims about her work.
Determine whether each claim Maya makes is correct. Select True or False for each claim.

sin 60 = √3/2
cot 30 = √3
Substituting values in equation,
3(√3/2)² + (√3)²
=> 3(3/4) + 3
=> 9/4 + 3
=> 9/4 + 12/4

You have an equation and a table with the x value given.
Replace x in the formula with the x value in the table and solve for y.
y = x^2 + 1
y = (-3)^2 + 1 = 9+1 = 10
y = (-2)^2 +1 = 4+1 = 5
y = (-1)^2 +1 = 1+1 = 2
y = (0)^2 + 1 = 0+1 = 1
y = (1)^2 +1 = 1+1 = 2
y = (2)^2 +1 = 4+1 = 5
y = (3)^2 +1 = 9+1 = 10

Answer:
The number of non-positive integral values of [tex]k[/tex] are contained in the following set:
[tex]S_{k} = \{-1, 0\}[/tex]
Step-by-step explanation:
Let be the following second order polynomial:
[tex]x^{2}-(k + 1)\cdot x + (k^{2}+k -8) = 0[/tex], [tex]k \le 0[/tex] (1)
Whose roots can be found by the Quadratic Formula:
[tex]x_{1,2} =\frac{k + 1\pm \sqrt{k^{2}+2\cdot k +1 - 4\cdot k^{2}-4\cdot k +32 }}{2}[/tex]
[tex]x_{1,2} = \frac{k+1}{2} \pm \frac{\sqrt{33-2\cdot k -3\cdot k^{2}}}{2}[/tex]
Based on the statement, we have the following system of inequations:
[tex]\frac{k+1}{2} + \frac{\sqrt{33 - 2\cdot k -3\cdot k^{2}}}{2} > 2[/tex] (2)
[tex]\frac{k+1}{2} - \frac{\sqrt{33 - 2\cdot k -3\cdot k^{2}}}{2} < 2[/tex] (3)
By (2) we have:
[tex]k + 1 + \sqrt{33-2\cdot k -3\cdot k^{2}} > 4[/tex]
[tex]\sqrt{33 -2\cdot k - 3\cdot k^{2}} > 4 - (k + 1)[/tex]
[tex]33 - 2\cdot k -3\cdot k^{2} > [4 - (k+ 1)]^{2}[/tex]
[tex]33 - 2\cdot k -3\cdot k^{2} > 16 -8\cdot (k+1)+(k+1)^{2}[/tex]
[tex]33 - 2\cdot k - 3\cdot k^{2} > 16-8\cdot k -8 + k^{2}+2\cdot k + 1[/tex]
[tex]33 - 2\cdot k -3\cdot k^{2} > 9 -6\cdot k + k^{2}[/tex]
[tex]0 > 4\cdot k^{2}-4\cdot k -24[/tex]
[tex]4\cdot k^{2}-4\cdot k -24< 0[/tex]
[tex]4\cdot (k^{2}-k-6) < 0[/tex]
[tex]k^{2}-k - 6 < 0[/tex]
[tex](k -3)\cdot (k+2) < 0[/tex]
The solution is:
[tex]k \in (-2, 3)[/tex]
Likewise, we get the following expression from (3):
[tex]k^{2}-k - 6 > 0[/tex]
[tex](k -3)\cdot (k + 2) > 0[/tex]
The solution is:
[tex]k \in (-\infty, -2)\,\cup\,(3, +\infty)[/tex]
The number of non-positive integral values of [tex]k[/tex] are contained in the following set:
[tex]S_{k} = \{-1, 0\}[/tex]
