The y-intercept of the line [tex]y = -5x \ is \ 0[/tex].
The equation of a line in slope-intercept form is given by [tex]$y = mx + b$[/tex], where [tex]$m$[/tex] represents the slope and [tex]$b$[/tex] represents the y-intercept. In the equation [tex]$y = -5x$[/tex], the coefficient of [tex]x \ \ is \ -5[/tex], which represents the slope of the line.
To find the y-intercept, we set [tex]$x$[/tex] equal to [tex]$0$[/tex] and solve for [tex]$y$[/tex]. Substituting [tex]$x = 0$[/tex] into the equation gives us [tex]$y = -5(0) = 0$[/tex].
Hence, the y-intercept of the line [tex]y = -5x \ is \ 0[/tex]. In the graph, the line passes through the origin [tex]$(0,0)$[/tex], indicating that it intersects the y-axis at [tex]$y = 0$[/tex]. This means the line passes through the point [tex]$(0, 0)$[/tex] on the coordinate plane. The y-intercept is the point at which the line crosses the y-axis.
The y-intercept is a crucial point on a line as it helps determine its starting position on the y-axis. In the graph, you can visually observe that the line passes through the origin, confirming the y-intercept of [tex]$0$[/tex].

Select two lines, preferably two that cross on your blueprint, and use the substitution
method to solve for their intersection point.
Mark each intersection point using a YELLOW POINT on your blueprint.
Repeat this for a total of three intersecting lines.
Example problem:
Y = -2X + 14 and Y = 3X-7
Intersection point = (4.2, 5.6)
-2X+14=3X-7
-2X=3X-21
5X=-21
X = 4.2
Y = -2(4.2) + 14
Y = -8.4 + 14
Y = 5.6
Marking the intersection points on the blueprint with yellow points:
Intersection point of Equations 1 and 2: (7, 0)Intersection point of Equations 1 and 3: (11.2, -8.4)Intersection point of Equations 2 and 3: (3.6, 3.8)How to determine intersection point?To solve for the intersection points of three lines.
Equation 1: Y = -2X + 14
Equation 2: Y = 3X - 7
Equation 3: Y = 0.5X + 2
To find the intersection point of Equations 1 and 2, use the substitution method.
Substituting Equation 1 into Equation 2:
-2X + 14 = 3X - 7
Adding 2X and subtracting 14 from both sides:
-2X + 2X + 14 = 3X + 2X - 7 - 14
14 = 5X - 21
Adding 21 to both sides:
14 + 21 = 5X
35 = 5X
Dividing both sides by 5:
X = 7
Now substitute X = 7 back into Equation 1 to find the corresponding Y value:
Y = -2(7) + 14
Y = -14 + 14
Y = 0
Therefore, the intersection point of Equations 1 and 2 is (7, 0).
To find the intersection point of Equations 1 and 3, use the same substitution method.
Substituting Equation 1 into Equation 3:
-2X + 14 = 0.5X + 2
Adding 2X and subtracting 14 from both sides:
-2X + 2X + 14 = 0.5X + 2X - 14
14 = 2.5X - 14
Adding 14 to both sides:
14 + 14 = 2.5X
28 = 2.5X
Dividing both sides by 2.5:
X = 11.2
Now substitute X = 11.2 back into Equation 1 to find the corresponding Y value:
Y = -2(11.2) + 14
Y = -22.4 + 14
Y = -8.4
Therefore, the intersection point of Equations 1 and 3 is (11.2, -8.4).
To find the intersection point of Equations 2 and 3, substituting Equation 2 into Equation 3:
3X - 7 = 0.5X + 2
Subtracting 0.5X and adding 7 to both sides:
3X - 0.5X = 0.5X + 2 + 7
2.5X = 9
Dividing both sides by 2.5:
X = 3.6
Now substitute X = 3.6 back into Equation 2 to find the corresponding Y value:
Y = 3(3.6) - 7
Y = 10.8 - 7
Y = 3.8
Therefore, the intersection point of Equations 2 and 3 is (3.6, 3.8).

A marketing manager for a cell phone company claims that less than 58% of children aged 8-12 have cell phones. In a survey of 822 children aged 8-12 by a national consumers group, 460 of them had cell phones. Can you conclude that the manager's claim is true? Use the α=0.10level of significance and the critical value method with the table.
Answer:
We want to test the null hypothesis that the proportion of children aged 8-12 who have cell phones is 0.58, against the alternative hypothesis that the proportion is less than 0.58.
The sample proportion is:
p = 460/822 = 0.559
The sample size is n = 822.
Under the null hypothesis, the test statistic follows a standard normal distribution. The test statistic is:
z = (p - P0)/sqrt(P0(1 - P0)/n)
where P0 is the hypothesized proportion under the null hypothesis.
Substituting the values we obtained, we get:
z = (0.559 - 0.58)/sqrt(0.58(1 - 0.58)/822) = -1.691
The critical value for a one-tailed test with a significance level of 0.10 and 821 degrees of freedom is -1.282. Since the test statistic (-1.691) is less than the critical value (-1.282), we reject the null hypothesis.
Therefore, we can conclude that there is sufficient evidence to support the claim that less than 58% of children aged 8-12 have cell phones.

The wheel on a car completes 25 revolutions in travels about 35.325 m rounded to the nearest centimeters, what is the diameter of the wheel use 3.14 for pi
The diameter of the wheel is approximately 45 cm.
To find the diameter of the wheel, we need to determine the circumference of the wheel using the number of revolutions and the distance traveled. The formula for the circumference of a wheel is given by:
Circumference = 2πr
where r is the radius of the wheel. Since we need to find the diameter, we can substitute r with d/2, where d is the diameter. The formula becomes:
Circumference = πd
We are given that the wheel completes 25 revolutions and travels about 35.325 meters. The distance traveled in one revolution is equal to the circumference of the wheel. Let's calculate the circumference of the wheel first:
Circumference = 35.325 m / 25 = 1.413 m
Now we can equate this to πd and solve for d:
1.413 = πd
To find the diameter, we divide both sides of the equation by π:
d = 1.413 / π ≈ 0.449 m
Finally, to convert the diameter to centimeters, we multiply by 100:
d ≈ 0.449 m * 100 ≈ 44.9 cm
Rounding this value to the nearest centimeter, the diameter of the wheel is approximately 45 cm.

g(x) shifts the graph vertically upward by 4 units,h(x) shifts the graph horizontally to the left by 7 units,k(x) scales the graph vertically by a factor of 20 and shifts it vertically upward by 10 units and m(x) compresses the graph horizontally by a factor of 1/4 and shifts it horizontally to the right by 1 unit.
To describe the graph of each function in terms of the graph of f(x) = 5 sin(x), we will analyze how each transformation affects the original graph.
1. g(x) = 5 sin(x) + 4:
Adding a constant value of 4 to the function f(x) shifts the graph vertically upward by 4 units. The amplitude and period of the graph remain the same.
2. h(x) = 5 sin(x + 7):
Adding a constant value of 7 inside the sine function causes a horizontal shift to the left by 7 units. This means the graph is shifted 7 units in the opposite direction of the sign (left in this case). The amplitude and period remain unchanged.
3. k(x) = 20 sin(x) + 10:
Multiplying the entire function by a constant of 20 scales the graph vertically, stretching it vertically by a factor of 20. Additionally, adding a constant value of 10 shifts the graph vertically upward by 10 units.
The amplitude remains the same, but the graph is vertically elongated and shifted upward.
4. m(x) = 5 sin(4x - 1):
Inside the sine function, the value of 4 stretches the graph horizontally by a factor of 1/4. This results in a shorter period, meaning the graph oscillates more frequently.
The value of -1 inside the sine function causes a horizontal shift to the right by 1 unit. Therefore, the graph is compressed horizontally and shifted 1 unit to the right. The amplitude remains the same.

a. What is true about every point that lies on this circle?
b. Algebraically show that the point (6, 8) lies on the circle.
The circle is:[tex]x^2+y^2 = 5^2 = 25[/tex]This circle has center (0,0) and radius 5 units. Therefore, it is a circle with a radius of 5 units, and every point that lies on the circumference of this circle is 5 units away from the center of the circle.
the distance between any point on the circle and the center of the circle is always 5 units. This is because the equation of a circle is
[tex](x-a)^2+(y-b)^2=r^2[/tex]
where the center is (a,b) and the radius is r units. In this case,
a=b=0 and r=5.
Algebraically show that the point (6, 8) lies on the circle.
To show that the point (6, 8) lies on the circle, we need to substitute the values of x and y in the equation of the circle and verify whether the equation holds true or not.So,
substituting x=6 and y=8 in the equation of the circle, we

Null hypothesis (H0): There is no significant relationship between GPA and the four variables.
Alternative hypothesis (Ha): There is a significant relationship between GPA and the four variables.
Step 2: Testing Assumptions - Normality
Research question: Is the assumption of normality violated for the four variables?
Null hypothesis (H0): The distribution of the four variables follows a normal distribution.
Alternative hypothesis (Ha): The distribution of the four variables does not follow a normal distribution
Next, you are instructed to create a descriptive statistics table in statistical software to assess normality. The table should include the four variables, along with their skewness and kurtosis values. Once you have created the table, you should paste it into the DAA Template.
After pasting the table, you will interpret the skewness and kurtosis values. Skewness measures the symmetry of the distribution, where a skewness value of 0 indicates perfect symmetry.
Positive skewness indicates a right-skewed distribution, while negative skewness indicates a left-skewed distribution. Kurtosis measures the peakedness or flatness of the distribution, with a kurtosis value of 3 indicating a normal distribution.
Positive kurtosis indicates a more peaked distribution (leptokurtic), while negative kurtosis indicates a flatter distribution (platykurtic).
Based on the skewness and kurtosis values, you will determine whether the assumption of normality is violated or not violated for the four variables.
