give example of a monotone subsequence of the sequence Sn=cos(n.π/3)
A monotone subsequence is a subsequence that is either increasing or decreasing, which we define as follows:
A sequence (S) is increasing if [tex]S_n \geq S_m[/tex] whenever n>m.A sequence (S) is decreasing if [tex]S_n \leq S_m[/tex] whenever n>m.Here, we can create a subsequence by taking every sixth term:
• When n = 6, [tex]S_n = \cos(6\pi /3) = \cos(2\pi) = 1[/tex]
• When n = 12, [tex]S_n = \cos(12 \pi /3) = \cos(4\pi) = 1[/tex],
and so on, and every such element will have a value of 1. This is a monotone subsequence.

Which value of x makes the equation 0.75(x + 20) = 2 + 0.5(x 2) true?
Answer:
[tex]x = -56[/tex]
Step-by-step explanation:
Given
[tex]0.75(x + 20) = 2 + 0.5(x - 2)[/tex]
Required
Find x
[tex]0.75(x + 20) = 2 + 0.5(x - 2)[/tex]
Open brackets
[tex]0.75x + 15 = 2 + 0.5x - 1[/tex]
Collect Like Terms
[tex]0.75x - 0.5x = 2 - 1 - 15[/tex]
[tex]0.25x = -14[/tex]
Solve for x
[tex]x = -\frac{14}{0.25}[/tex]
[tex]x = -56[/tex]

Answer:
Step-by-step explanation:
Compound inequality has been given as,
12(2x - 10) + 24 ≥ 48 Or 6x + 15 - 9x ≥ 6
By simplifying it further,
12(2x - 10) + 24 ≥ 48
[tex]\frac{12(2x - 10)}{12}+\frac{24}{12}\geq \frac{48}{12}[/tex]
(2x - 10) + 2 ≥ 4
(2x - 10) + 2 - 2 ≥ 4 - 2
2x - 10 ≥ 2
2x - 10 + 10 ≥ 2 + 10
2x ≥ 12
[tex]\frac{2x}{2}\geq \frac{12}{2}[/tex]
x ≥ 6
6x + 15 - 9x ≥ 6
(6x - 9x) + 15 ≥ 6
(-3x) + 15 ≥ 6
-3x + 15 - 15 ≥ 6 - 15
-3x ≥ -9
3x ≤ 9
x ≤ 3
We have to plot the inequality on a number line
x ≥ 6 Or x ≤ 3
Determine if the correlation between the two given variables is likely to be positive or negative, or if they are not likely to display a linear relationship. The retail price of a particular smartphone and the number of units sold at that price
Answer:
no correlation
Step-by-step explanation:
The price of the smartphone is fixed beforehand, therefore price does not depend upon the number of units sold.
Hence, there is no correlation between the two given variables.
Hence, no correlation would be the answer.

12. What is the slope of line with the points (2,2) and (1,5)?
Answer:
- 3Step-by-step explanation:
The slope of a line given two points can be found by using the formula
[tex]m = \frac{ y_2 - y _ 1}{x_ 2 - x_ 1} \\[/tex]
From the question we have
[tex]m = \frac{5 - 2}{1 - 2} = - \frac{3}{1} = - 3 \\ [/tex]
We have the final answer as

12. (03.03 MC) The equation below represents Function A and the graph represents Function B: Function A f(x) = 6x - 1 Function B 4 2 + 1 -2 1 -1 -2 -4 t -5
Answer:
Ans : = 0
Step-by-step explanation:
Answer:
[tex]\textsf{Slope of Function A = 2 x Slope of Function B}[/tex]
Step-by-step explanation:
We know that Function A is given by:
[tex]f(x)=6x-1[/tex]
And we are given the graph of Function B.
And we are asked to compare the slopes of the two functions.
So, we will determine the slope of each.
For Function A, the slope is simply the coefficient of our independent variable x.
Since 6 is our coefficient, the slope of Function A is 6.
For Function B, we will utilize the slope formula, given by:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We will need any two points from our graph. Let’s use (0, 1) and (-1, -2).
So, we will let (0, 1) be (x₁, y₁) and (-1, -2) be (x₂, y₂). Substitute appropriately:
[tex]\displaystyle m=\frac{-2-1}{-1-0}[/tex]
Evaluate:
[tex]\displaystyle m=\frac{-3}{-1}=3[/tex]
So, the slope of Function B is 3.
Therefore, the slope of Function A is twice the slope of function B.
So, we can write that:
[tex]\textsf{Slope of Function A = 2 x Slope of Function B}[/tex]

McAllister et al. (2012) compared varsity football and hockey players with varsity athletes from noncontact sports to determine whether exposure to head impacts during one season have an effect on cognitive performance. In the study, tests of new learning performance were significantly poorer for the contact sport athletes compared to the noncontact sport athletes. The following table presents data similar to the results obtained in the study.
Noncontact Athletes:
10, 8, 7, 9, 13, 7, 6, 12
Contact Athletes:
7, 4, 9, 3, 7, 6, 10, 2
a. Are the test scores significantly lower for the contact sport athletes than for the noncontact athletes? Use a one-tailed test with \alpha=.05
t-critical=
t=
b. Compute the value of (percentage of variance accounted for) for these data.
r^2= a. 0.123, b. 0.239, c. 0.138, d. 0.264
Answer:
[tex]t _{critical} = 1.760[/tex]
t = 2.2450
d. 0.264
Step-by-step explanation:
The null hypothesis is:
[tex]H_o: \mu_1 - \mu_2 = 0[/tex]
Alternative hypothesis;
[tex]H_a : \mu_1 - \mu_2 > 0\\[/tex]
The pooled variance t-Test would have been determined if the population variance are the same.
[tex]S_p^2 = \dfrac{(n_1-1)S_1^2+(n_2-1)S^2_2}{(n_1-1)+(n_2-1)}[/tex]
[tex]S_p^2 = \dfrac{(8-1)2.507^2+(8-1)2.8282^2}{(8-1)+(8-1)}[/tex]
[tex]S_p^2 = 7.14[/tex]
The t-test statistics can be computed as:
[tex]t= \dfrac{(x_1-x_2)-(\mu_1 - \mu_2)}{\sqrt{Sp^2 ( \dfrac{1}{n} +\dfrac{1}{n_2})}}[/tex]
[tex]t= \dfrac{(9-6)-0}{\sqrt{7.14 ( \dfrac{1}{8} +\dfrac{1}{8})}}[/tex]
[tex]t= \dfrac{3}{1.336}[/tex]
t = 2.2450
Degree of freedom [tex]df = (n_1 -1) + ( n_2 +1 )[/tex]
df = (8-1)+(8-1)
df = 7 + 7
df = 14
At df = 14 and ∝ = 0.05;
[tex]t _{critical} = 1.760[/tex]
Decision Rule: To reject the null hypothesis if the t-test is greater than the critical value.
Conclusion: We reject [tex]H_o[/tex] and there is sufficient evidence to conclude that the test scores for contact address s less than Noncontact athletes.
To calculate r²
The percentage of the variance is;
[tex]r^2 = \dfrac{t^2}{t^2 + df}[/tex]
[tex]r^2 = \dfrac{2.2450^2}{2.2450^2 + 14}[/tex]
[tex]r^2 = \dfrac{5.040025}{5.040025+ 14}[/tex]
[tex]r^2 = 0.2647[/tex]

32 A bicycle seller found that if he sells
a bicycle for L.E. 1656 , his loss will be 8 %
Find the cost price of the bicycle and find
the selling price that makes him get a profit
of 12 %
Answer:
L.E. 1,800L.E. 2,016Step-by-step explanation:
1. Cost price of bike.
Let cost price be x;
x * (100% - 8%) = 1,656
0.92x = 1,656
x = 1,656/0.92
x = L.E. 1,800
2. Selling price for 12% profit;
= 1,800 * ( 1 + 12%)
= L.E. 2,016

Determine the value of x and y
Answer:
x=65, y=60
Step-by-step explanation:
x=65--->corrosponding angles with the triangle
x+y+55=180--->linear pair
(65)+y+55=180
y=60
Answer:
x=65 y=60
Step-by-step explanation:
Well, divide the hypotenuse between two triangles added onto the square root of the divisions between Mars and Pluto and we can derive the positive neutrons of the seventeenth quadratic of the Einstein constant equation.
or, know that x=65 due to it being on a parallel line to it, then due to their being 360 degrees around a point, 65+65+55+55=240, 360-240=120, then divide that by two to get it at y.

identify the slope and y-intercept of the line given below y=5x-1
Answer:
Slope: 5
Y-intercept: -1
Step-by-step explanation:
This equation is written in slope-intercept form, y=mx+b, where m is the slope and b is the y-intercept.
From this, we can see that 5 is m and -1 is b.
Therefore, the slope is 5 and the y-intercept is -1
Hope this helps! :)
