A procedure for using sample data to find the estimated regression equation is (c) the least squares method.
The least squares method is a commonly used statistical procedure for finding the estimated regression equation by minimizing the sum of the squared differences between the observed and predicted values.
The goal of this method is to find the line of best fit that closely represents the relationship between the independent and dependent variables in the sample data. The regression equation obtained from the least squares method can be used to make predictions about the dependent variable based on the values of the independent variable.

Rina spins the spinner below 30 times. A success occurs when the spinner lands on a number that is greater than 6.
A spinner is divided into 8 equals sections and the sections are labeled 1 through 8.
What is the probability of a success and a failure for this experiment?
P (success) = one-fourth; P (failure) = Seven-eighths
P (success) = one-fourth; P (failure) = Three-fourths
P (success) = three-fourths; P (failure) = one-fourth
P (success) = seven-eighths; P (failure) = One-eighth
The probability of an event can not be more than the number 1.
The probability of success is 1/4.The probability of failure is 3/4.What is probability?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
As the probability of an event can not be more than the number 1.
Thus the probability of failure of a event is equal to the difference of the 1 to the success of the event. As,
[tex]Probability[/tex] [tex]of[/tex] [tex]faliure=1-[/tex] [tex]Probability[/tex] [tex]of[/tex] [tex]success[/tex]
Given information-Rina spins the spinner less than the 30 times.
A success occurs when the spinner lands on a number that is greater than 6.
A spinner is divided into 8 equals sections and the sections are labeled 1 through 8.
As the probability of success occurs when the spinner lands on a number that is greater than 6, thus the number should grater than six.
This number should be less than 30 as the spinner spins less than the 30 times.
Thus the total number of outcome of this event is,
[tex]=30-6[/tex]
[tex]=24[/tex]
Thus the probability of success is,
[tex]P=\frac{6}{24}[/tex]
[tex]P=\frac{1}{4}[/tex]
Hence the probability of success is 1/4.
As the probability of failure of a event is equal to the difference of the 1 to the success of the event.
Thus the probability of failure is,
[tex]P^-=1-P[/tex]
[tex]P^-=1-\frac{1}{4}[/tex]
[tex]P^-=\frac{4-1}{4}[/tex]
[tex]P^-=\frac{3}{4}[/tex]

An August 2022 report from The College Board states that, among all test takers who graduated high school in 2022 , the average SAT score was 1050 points, with a standard deviation of 216 points. The SAT score distribution can be assumed to follow a normal distribution. Question 3 Subquestions 3.a 1 point(s) Let a test taker who scores more than 1320 points be considered a top performer. What proportion of test takers are considered top perfors?

20%
of the distribution? If a test taker has scored in the top
20%
of the distribution, what is the likelihood that the test taker is a top performer? Recall that a test taker who scores more than 1320 points is considered a top performer.

0.727
0.627
0.704
0.528
The proportion of test takers that are considered top performers is given as follows:
0.1056.
The minimum SAT score needed for a test taker to be in the top 20% is given as follows:
1231.
How to obtain probabilities using the normal distribution?The z-score of a measure X of a variable that has mean symbolized by [tex]\mu[/tex] and standard deviation symbolized by [tex]\sigma[/tex] is obtained by the rule presented as follows:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.The mean and the standard deviation of SAT scores are given as follows:
[tex]\mu = 1050, \sigma = 216[/tex]
The proportion of scores above 1320 points is one subtracted by the p-value of Z when X = 1320, hence:
Z = (1320 - 1050)/216
Z = 1.25
Z = 1.25 has a p-value of 0.8944
1 - 0.8944 = 0.1056.
The minimum SAT score needed for a test taker to be in the top 20% is the 80th percentile, which is X when Z = 0.84, hence:
0.84 = (X - 1050)/216
X - 1050 = 216 x 0.84
X = 1231.

What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (- 7, -3) and (-3, 5).
Now,
Since, The equation of line passes through the points (- 7, -3) and (-3, 5).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (5 - (-3)) / (-3 - (-7))
m = 8 / 4
m = 2
Thus, The equation of line with slope 2 is,
⇒ y - (-3) = 2 (x - (-7))
⇒ y + 3 = 2 (x + 7)
⇒ y + 3 = 2x + 14
⇒ y = 2x + 14 - 3
⇒ y = 2x + 11
Therefore, The equation of line passes through the points (- 7, -3) and

b) What conclusion (reject or fail to reject) would you make for this test?
c) If this test resulted in a decision error, what type of error was it?
With a significance test about a proportion is conducted using a significance level of 0.05, sample statistic is 0.12, p-value is 0.03.
a) If H0 were true, the test was designed for a probability of a Type I error of 0.05.
b) Based on the p-value of 0.03, you would reject the null hypothesis.
c) If this test resulted in a decision error, it would be a Type II error.
a) If H0 were true, the test was designed for a probability of a Type I error of 0.05. When conducting a hypothesis test, we set a significance level, often denoted by alpha (α), to control the probability of making a Type I error.
A common value for alpha is 0.05, which means that we are willing to accept a 5% chance of making a Type I error.
b) Based on the p-value of 0.03, which is less than the significance level of 0.05, you would reject the null hypothesis. This means that the sample statistic provides enough evidence to suggest that the population proportion is different from the hypothesized value.
c) If this test resulted in a decision error, it would be a Type II error. A Type II error occurs when you fail to reject a false null hypothesis. In this case, the p-value of 0.03 suggests that the population proportion is different from the hypothesized value, so if the null hypothesis were actually false and you still failed to reject it, it would be a Type II error.

It is a symmetrical, U-shaped curve that is created by the intersection of a plane and a right circular cone. The shape of the curve is defined by its equation, which can be expressed in standard form as y = ax^2 + bx + c. In this equation, the coefficient a determines the shape of the parabola, with a positive value creating an upward-opening parabola and a negative value creating a downward-opening parabola.
The focus of a parabola is (0,-2). The directrix is the line y = 0. What is the equation of the parabola in vertex form?The vertex of a parabola is equidistant from the focus and the directrix. Since the directrix is the line y = 0, which is the x-axis, the vertex is halfway between the focus and the x-axis, at (0, -1).
The distance from the vertex to the focus is p, which is also the distance from the vertex to the directrix. Since the directrix is the line y = 0, the distance from the vertex to the directrix is simply the y-coordinate of the vertex, which is 1.
Therefore, p = 1, and the equation of the parabola in vertex form is:
y = 1/4p(x - h)^2 + k = 1/4(1)(x - 0)^2 - 1 = 1/4x^2 - 1
in the equation y= 1/4p(x-k)² +h, the value of p is 1.
The vertex of the parabola is the point (0, -1).
The equation of this parabola in vertex form is y = 1/4x^2 - 1.
To solve 2²-1:
2² - 1 = 4 - 1 = 3.

Scott's statement that (13g + 1) + (-2 - 5g) and 8/3(3g + 9/8) are equivalent is wrong
How to determine if he is right or notFrom the question, we have the following parameters that can be used in our computation:
(13g + 1) + (-2 - 5g)
Remove the brackets
So, we have
13g + 1 - 2 - 5g
Evaluate the like terms
8g - 1
When factorized, we have
8/3(3g - 3/8)
This is not the same as Scott's expression
Hence, Scott is incorrect

d) The cheetah traveled 1.75 times faster for the first 8 minutes than it did for the second 8 minutes. Was the distance traveled during the first 8 minutes 1.75 times greater than the distance traveled during the second 8 minutes
The distance traveled in the first 8 minutes is 1.75 d2
What is speed?Speed is the rate of change of distance with time. it is a scalar quantity and it is measured in meter per second.
speed = distance /time
time = distance /speed
total time = 16
represent u by the first 8minutes and v by the second 8 minutes
u = 1.75v
8 = d1/1.75v
8 = d2/v
d1/1.75v = d2/v
d1 ×v = 1.75v × d2
d1 = 1.75d2
therefore ;
d1 = 1.75d2
where d1 and d2 are the distances for the first 8 minutes and second 8minutes respectively.
therefore the distance in the first 8minutes is 1.75 times greater than the second 8 minutes

The solution of both inequalities is (-1, 2).
What is Inequality?Mathematical expressions with inequalities are those in which the two sides are not equal. Unlike to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.
Given:
We have the inequalities
x+ y >1.........(1)
-x+ y <3.........(2)
The graph for x+ y >1 is shown by the red shaded region.

Given that a triangle UVW in which the angle W is 41 degrees.
V is 100 degrees.
We have to find the angle U.
By angle sum property we have the sum of three angles is 180 degrees.
∠U+∠V+∠W=180
∠U+100+41=180
∠U+141=180
Substitute 141 from both sides
∠U=180-141
∠U=39 degrees.
Hence, the angle U is 39 degrees, when W is 41 degrees and V is 100 degrees.
