identify the slope and y-intercept of the line given below y=5x-1
Answers
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

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 %
Answers
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

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

Which value of x makes the equation 0.75(x + 20) = 2 + 0.5(x 2) true?
Answers
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]
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
Answers
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]

give example of a monotone subsequence of the sequence Sn=cos(n.π/3)
Answers
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.

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]
