Answer:
Weak Positive Correlation
Step-by-step explanation:
The r value of 0.15 indicates a weak positive correlation value because a weak correlation value is less than 0.3, anything between 0.3 and 0.7 are a moderate correlation, and anything greater than 0.7 would be a string correlation. So, since this is less than 0.3, this is a weak correlation. A positive correlation is a positive value and a negative correlation value is a negative number, so this would be a weak positive correlation value.
A value of r = 0.15 suggests a weak positive correlation, indicating a slight tendency for the variables.
As per the question, the value of r is positive (greater than 0), which suggests a positive correlation between the variables.
However, the value of 0.15 is close to 0 and relatively small, indicating a weak correlation.
This means that there is a weak tendency for the variables to increase or decrease together.
Thus, a value of r = 0.15 suggests a weak positive correlation, indicating a slight tendency for the variables to increase or decrease together, but the relationship is not strong.

An eight-sided die has the numbers 1 through 8 on its eight faces. What is 2 points
the expected value when rolling the die? *
O 3.6
04
4.5
06
Answer:
4.5
Step-by-step explanation:
(1/8)*1 + (1/8)*2 + (1/8)*3 + ... +(1/8)*8
or
(1/8)*(1 2 + 3 + 4 + 5 + 6 + 7 + 8) = (1/8)*36 = 4.5
We can use a shortcut to sum the numbers 1 through 8. It is given by 8*(8+1)/2.
two friends bought a strip of tickets for the school carnival. Arlo used 5/6 of his tickets. jayson used 6/6 of his tickets.
::::::::::::::::::::
Answer:
total number of tickets bought: 12
total number of tickets used: 11
Jayson used 1 more ticket than Arlo
Step-by-step explanation:
Erm, I don't know what you want answered, but here's some basics:
So to find how many total tickets were bought, we just have to add both of the strips together:
6 + 6 = 12
So the total number of tickets bought was 12.
To find the amount of ticket used, you have to add the top numbers together:
5 + 6 = 11
So the total number of tickets used is 11.
If you wanted to find how many more tickets Jayson used than Arlo, you'd have to subtract Arlo's tickets from Jayson's:
6 - 5 = 1
So Jayson used 1 more ticket than Arlo.

A baseball team plays in a stadium that holds 54000 spectators. With the ticket price at $8 the average attendance per game has been 20000. When the price dropped to $6, the average attendance rose to 27000. Assume that attendance is linearly related to ticket price.

What ticket price would maximize revenue? (round to the nearest cent)
9514 1404 393
Answer:
R(p) = -3500p^2 +48000p . . . revenue function
$6.86 . . . price for maximum revenue
Step-by-step explanation:
The 2-point form of the equation for a line can be used to find the attendance function.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (27000 -20000)/(6 -8)(x -8) +20000
y = -3500(x -8) +20000
y = 48000 -3500x . . . . y seats sold at price x
The per-game revenue is the product of price and quantity sold. In functional form, this is ...
R(p) = p(48000-3500p)
R(p) = -3500p^2 +48000p . . . per game revenue
__
Revenue is maximized when its derivative is zero.
R'(p) = -7000p +48000
p = 48/7 ≈ 6.86
A ticket price of $6.86 would maximize revenue.
You buy tomatoes in 25-pound cases. One batch of Cobb salad requires 1.1 ounces of tomatoes. How many portions can be made with one case? Round down (don’t include partial portions).
Answer:
363 portions can be made with one case.
Step-by-step explanation:
Since I buy tomatoes in 25-pound cases, and one batch of Cobb salad requires 1.1 ounces of tomatoes, to determine how many portions can be made with one case, the following calculations must be performed:
1 pound = 16 ounces
25 pounds = 400 ounces
400 / 1.1 = 363.63
Therefore, 363 portions can be made with one case.

9514 1404 393
Answer:
1, 2: draw x as the altitude of a right triangle
3: draw x as double the altitude of the right triangle
Step-by-step explanation:
Consider the right-triangle geometry in the attachment. All of the right triangles are similar, so the ratios of corresponding sides are equal.
short side / long side = x/r = s/x
You may notice this compares to the required relation in problem 1.
__
If you multiply this out, you get ...
x² = rs ⇒ x = √(rs)
This compares to the required relation in problem 2.
__
So, you append the two line segments to each other so they make segment AB, find their midpoint D (using a perpendicular bisector construction), then draw the (semi-)circle centered at that midpoint. The perpendicular at X will intersect the circle at C, a distance of x from the line rs. (A perpendicular to a line at a point construction is required to create XC.)
__
For problem 3, you simply need to double the length √(rs) that you found in the previous constructions. A simple way to do this is to draw a circle, not a semicircle. Then point C' on the lower half of the circle will be 2√(rs) from point C.
_____
In the attached, we have shown right triangle ABC for discussion purposes above. Segments AC and BC are not needed for your purpose.
Point of clarification: AX = r, BX = s, CX = x.

Complete question :
Alligators perform a spinning maneuver, referred to as a "death roll," to subdue their prey. In a study of alligator death rolls, one of the variables measured was the degree of the angle between the body and head of the alligator while performing the roll. A sample of 20 rolls yielded the data provided below, in degrees. At the 1% significance level, do the data provide sufficient evidence to conclude that, on average, the angle between the body and head of an alligator during a death roll is greater than 45 ? Note: x =46.255° and s = 12.251° Preliminary data analyses indicate that you can reasonably use a t test to conduct the hypothesis test.
Answer:
H0 : μ = 45
H1 : μ > 45
T statistic = 0.4472
Pvalue = 0.3299
We fail to reject the Null
Step-by-step explanation:
H0 : μ = 45
H1 : μ > 45
Test statistic, T :
(xbar - μ) ÷ (s/√n)
(46.225 - 45) ÷ (12.251/√20)
1.225 ÷ 2.7394068
= 0.4472
Using the Pvalue calculator, the Pvalue can be obtained using the test statistic and degree of freedom
Degree of freedom, df = 20 - 1 = 19
Tscore = 0.4472
α = 0.01
Pvalue = 0.3299
Pvalue > α
0.3299 > 0.01 ; Hence, we fail to reject the Null
We fail to reject the Null; The data does not provide sufficient evidence to conclude that average angle between alligator's body and its head is greater than the 45

A chi-square test of independence was conducted to investigate whether there is an association between the location where a person lives in a city (north, south, east, or west) and who the person planned to vote for in the upcoming mayoral election (the incumbent or the challenger). A random sample of 100 potential voters was selected, and the hypothesis test had a chi-square test statistic of x^2=9.84 with a p-value of 0.02. Which of the following statements is the correct interpretation of the pp-value in context?
a. There is a 2 percent chance that where a person lives and who that person plans to vote for are independent.
b. There is a 2 percent chance that where a person lives and who that person plans to vote for are dependent.
c. There is a 2 percent chance of making a Type IIII error.
d. Assuming that the location of where a person lives and who that person plans to vote for are dependent, there is a 2 percent chance of finding a test statistic that is 9.84 or greater.
e. Assuming that the location of where a person lives and who that person plans to vote for are independent, there is a 2 percent chance of finding a test statistic that is 9.84 or greater.
Answer:
The answer is "Option e".
Step-by-step explanation:
The Chi-Square Independence Test determines if the variables or linked among measurement items factors. It test is indeed not symmetric. It is also known as Interaction Chi-Square Test. Therefore it is also a 2% likelihood of obtaining a test statistic which is 9.84 or higher unless the place where a person is living, but for whom each plans to vote is different.
Omar the tent maker wishes to support a 13.4-ft tent wall by attaching 25-ft cable to the top of it, and then anchoring the cable to the ground. If the cable is pulled tight, how far from the base of the tent will it be anchored?
Answer:
21.11 ft
Step-by-step explanation:
This question would be solved using Pythagoras theorem
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
13.4² + b² = 25²
179.56 + b² = 625
b² = 625 - 179.56
b = 445.44
find the square root of 445.44
b = 21.11 ft
