Which one of these formulas describes the following sequence?
1,5,12,22,35
We can find a formula for nth term of the given sequence as follows:
1, 5, 12, 22, 35
The 1st differences between terms:
4, 7, 10, 13
The 2nd differences :
3, 3, 3
Since it takes two rounds of differences to arrive at a constant difference between terms, the nth term will be a 2nd degree polynomial of the form: [tex]a n^2 + b n + c[/tex], where c is a constant. The coefficients a, b, and the constant c can be found.
We can form the following 3 equations with 3 unknowns a, b, c:
[tex]1 = a\cdot1^2 + b\cdot1 + c\\5 = \cdot2^2 + b\cdot2 + c\\12 = a\cdot3^2 + b\cdot3 + c[/tex]
Solving for a, b, c, we get:
a = 3/2, b = -1/2, c = 0
Therefore, the nth term of the given sequence is:
[tex]\boxed{ a_n = \dfrac{3}{2}n^2- \dfrac{1}{2} n}[/tex]

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.

Before attending a basketball course, a player found that 60% of his shots made a
score. After attending the course, the player claimed he had improved. In his next
game he tried 12 shots and scored in 10 of them. Assuming shots to be
independent, test his claim at the 10% level of significance
Answer:
Step-by-step explanation:
60% = 7.2/12
83% = 10/12
He improved by a supposed 23%

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]
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]

Leah and Dan are trying to prove that the triangles below are congruent. Leah says they are congruent by the AAS congruence criteria, while Dan says they are congruent by the ASA congruence criteria. Who is correct? Explain.
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

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]
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.
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
