Andrew drives through 5 intersections with stop lights on his way to work. He records that he is stopped by a red light in 2 of the 5 intersections. If he uses this as his general probability of getting stopped at a red light on his way to or from work, how many times can he expect to be stopped at a red light over the next 40 times he drives through an intersection on his route?
Andrew should expect to be stopped ____
times.
Answers
Answer:
He should expect to be stopped a total of 16 times
Step-by-step explanation:
What the question is saying is that out of every 5 intersections, he would be stopped at 2.
Now, for forty times in which he passes through an intersection , we want to know the number of times in which he would be stopped
In this case we only need to multiply the probability by the number of times in which he passes an intersection and that would be 2/5 * 40 = 16 times
Answer:
16 times

The scatter plot of fees versus days taken to fill a job for Sarin Employment's sample data suggests that there may be a positive linear relationship between the two variables.
a. To construct a scatter plot in Excel, we would plot the fees on the y-axis (dependent variable) and the days taken to fill a job on the x-axis. Each data point would be represented as a dot on the graph.
Next, to calculate the correlation coefficient and test for statistical significance, we can use a statistical calculator or software. In this case, since the alpha level is given as 0.05, we will use a significance level of 0.05 for our hypothesis test.
b. The correlation coefficient, also known as the Pearson correlation coefficient, measures the strength and direction of the linear relationship between two variables. It ranges from -1 to 1, where -1 indicates a perfect negative linear relationship, 0 indicates no linear relationship, and 1 indicates a perfect positive linear relationship.
To test for statistical significance, we will conduct a hypothesis test with the following hypotheses:
Null Hypothesis (H0): There is no statistically significant linear relationship between fees and days taken to fill a job.
Alternative Hypothesis (H1): There is a statistically significant linear relationship between fees and days taken to fill a job.
We will use a two-tailed test since we are interested in determining whether there is any linear relationship, regardless of the direction.
If the calculated p-value is less than our chosen significance level of 0.05, we will reject the null hypothesis and conclude that there is a statistically significant linear relationship between fees and days taken to fill a job.
Therefore, by analyzing the scatter plot and conducting a hypothesis test, we can determine the apparent relationship between fees and days taken to fill a job and assess whether it is statistically significant.

Answers
The graph shows the relationship between the number of students who attend a homecoming dance and the amount of money raised. The graph is a straight line with a slope of $10, passing through the point (0, $80) and another point on the line. The fixed cost for decorations is $80, which is a constant cost that does not depend on the number of students attending the dance. For each additional student that attends the dance, the amount of money raised will increase by $10.
Answer:
y = 10x - 80

What are the roots of x2 5x − 6?
Answers
The roots of polynomial x2 5x − 6 are x = 3 and x = -2.
Factor the polynomial
x2 5x − 6 = (x - 3)(x + 2)
(x - 3) = 0
x - 3 = 0
x = 3
(x + 2) = 0
x + 2 = 0
x = -2
To find the roots of the equation x2 5x - 6, we must first factor the polynomial into two terms. The equation can be factored as (x - 3)(x + 2). We then have to set each factor equal to zero. For the first factor, (x - 3) = 0. With this equation solved, we obtain x = 3. (x + 2) Equals 0 for the second factor. The answer to this problem is x = -2. As a result, x = 3 and x = -2 are the roots of x2 5x - 6.

(1 point) a poll is taken in which 302 out of 525 randomly selected voters indicated their preference for a certain candidate. (a) find a 95% confidence interval for p.
Answers
Using the standard z table, a 95% confidence interval for p is (0.5327,0.6173).
In the given question,
A poll is taken in which 302 out of 525 randomly selected voters indicated their preference for a certain candidate.
We have to find a 95% confidence interval for p.
From the question, x=302, n=525
So estimation point,
P=x/n
P=302/525
P=0.575
Now the z value of 95% confidence interval is 1.960 using the standard z table.
Margin of Error (E)=z×√{P(1−P)}/n
Now putting the value
E=1.960×√{0.575(1−0.575)}/525
E=1.960×√(0.575×0.425)/525
E=1.960×√0.244/525
E=1.960×√0.000465
E=1.960×0.0216
E=0.0423
At 95% confidence interval for p is
P−E ≤ p ≤ P+E
Now putting the value
0.575−0.0423≤ p ≤0.575+0.0423
0.5327≤ p ≤0.6173
Hence, a 95% confidence interval for p is (0.5327,0.6173).

store A has 23 shelves; on each shelf there are 10 boxes. Store A has 9 more shelves than store B (each shelf with 10 boxes). In all, how many shelves, with 10 boxes each, does store b have?
Answers
store B has 23 shelves, with 10 boxes on each shelf.
Store A has 23 shelves, with 10 boxes on each shelf. To find the total number of boxes in store A, we multiply the number of shelves by the number of boxes per shelf:
Total boxes in store A = 23 shelves * 10 boxes per shelf = 230 boxes
We are given that store A has 9 more shelves than store B, with each shelf having 10 boxes. Let's represent the number of shelves in store B as 'x'. Therefore, the total number of boxes in store B would be:
Total boxes in store B = x shelves * 10 boxes per shelf = 10x boxes
We know that the total number of boxes in store A is 230, so we can set up an equation:
230 = 10x
To solve for 'x', we divide both sides of the equation by 10:
230 / 10 = x
23 = x

How many intersections are there of the graphs of the equations below? one-halfx 5y = 6 3x 30y = 36
Answers
The number of intersections of the graphs of the given equations is 0.
To determine the number of intersections of the graphs of the equations:
1. One-halfx + 5y = 6
2. 3x - 30y = 36
We can convert the equations to slope-intercept form (y = mx + b) by isolating y:
1. \(\frac12\\\)x + 5y = 6
5y = -\(\frac12\\\)x + 6
y = (-1/10)x + 6/5
2. 3x - 30y = 36
-30y = -3x + 36
y = (1/10)x - 36/30
y = (1/10)x - 6/5
Now, we can observe that both equations have the same slope, which is 1/10, but they have different y-intercepts (6/5 and -6/5).
Since the slopes are the same but the y-intercepts are different, the two lines are parallel.
Parallel lines do not intersect,
so the graphs of these equations have no intersection points.
