Answer:
Step-by-step explanation:
(-5, 2), (5, -1)
(-1 - 2)/(5+5)= -3/10
y - 2 = -3/10(x + 5)
y - 2 = -3/10x - 3/2
y - 4/2 = -3/10x - 3/2
y = -3/10x + 1/2

Answer:
[tex]\huge\boxed{\sf 90\ degrees}[/tex]
Step-by-step explanation:
P is the center of the circle
Chord RL passes through the center of the circle. Hence it is the diameter of the circle.
According to Thales's Theorem: (The angle opposite to the diameter is 90 degrees when a triangle is drawn in that semi-circle)
=> m∠REL = 90°

The weights of eight puppies have the following statistics:
mean: 10
median: 7.5
mode: 7
List one set of possible weights in the table below.
Answer:
7, 7, 7, 7.5, 7.5, 14, 20, 10
Step-by-step explanation:
Since the median has to be 7.5, you know that the 4th and 5th numbers have to average out to 7.5. In simpler terms, the two numbers have to add up to 15 so that when you divide them by 2, you get 7.5. Then you know that the mode is 7. So, the magority of the numbers have to be 7. This is why I made the first 3 numbers 7. Then you know that the mean is 10, so all the numbers have to add up to 80. So, if you add up the numbers you have so far you get 36. This means that the remaning numbers have to add up to 44. Here you can really choose any numbers you want, as long as they add up to 44. That is why I chose, 14, 20, and 10. Lastly to check the numbers you put in, find the mean, median and mode. If they all match up with median: 7.5, mean: 10, and mode: 7, then your numbers work! Hope that helps!

One possible data set can be -
8, 7, 8, 7, 8, 7, 15, 7, 13
We have the following statistics for weights of eight puppies -
Mean: 10
Median: 7.5
Mode: 7
We have to list the set of possible weights for eight puppies.
Define Mean, Median and Mode for a given set of data.The mean (average) of a data set is found by adding all numbers in the data set and then dividing by the number of values in the set.
The median is the middle value when a data set is ordered from least to greatest.
The mode is the number that occurs most often in a data set.
According to the question, we have -
Number of puppies = 8
Mean = 10
Median = 7.5
Mode =7
Assume the sum of weights of all puppies be x. Therefore -
[tex]$\frac{x}{8} = 10[/tex]
x = 80
Now -
Mode = 7 → This means that the number 7 has occurred the most in the set.
Median = 7.5 → This means that 7 is the middle value when a data set is ordered from least to greatest. The data set can be -
8, 7, 8, 7, 8, 7, 15, 7, 13
Hence, one possible data set can be -
8, 7, 8, 7, 8, 7, 15, 7, 13

8.36 Football and Brain Size: Randomization Test Exercise 8.35 describes a study examining hippocampus volume in the brain between controls who have never played football, football players with no history of concussion, and football players with a history of concussion. The data are available in FootballBrain. Use StatKey or other technology to conduct an ANOVA randomization test to determine whether there is a significant difference in mean hippocampus volume between the three categories. What is the F-statistic for the observed data
Answer:
Since the calculated F= 2.8657 does not lie in the critical region F (2,2)≥ 19 we conclude that there no difference between the means.
Since the calculated F= 205.0819 lies in the critical region F(1,2) ≥ 18.51 we conclude that there is a difference between the standard deviations of the three groups.
The F- statistic for the observed data is 0.101 as calculated by F- test in excel.

To conduct an ANOVA randomization test we perform anova without replication in excel.

Please help due in 10 min!!! Solve for X
Answer:
x == 9
Step-by-step explanation:
Angle at the vertex is half the difference of those at the intercepted arcs;
35 = 1/2(120-15x+5)
35 * 2 = 120-15x-5
70 = 115 - 5x
70 - 115 = -5x
-45 = -5x
x = 45/5
x = 9
Hence the value of x is 9
Police body cameras: A survey of New York State residents asked about police officers having to wear video cameras on duty. The question stated, "Do you agree or disagree that police officers should carry video cameras for the purposes of filming their activities while on duty?" Most (88%) respondents agreed with this statement. Do Californians share the same opinion? A California-based civil rights group conducted a similar survey by randomly selecting 500 California residents, and 425 agreed that police officers should carry video cameras for the purposes of filming their activities while on duty. Conduct a hypothesis test to determine if the proportion of California residents who agree is different from New York residents. Use a 5% significance level to make your decision. Use the applet (at the top of this Checkpoint) to determine the P-value. Which of the following is an appropriate conclusion based on the results?
a. The survey provides strong evidence that the proportion of California residents who agree that police officers should carry video cameras for the purposes of filming their activities while on duty is significantly different from the proportion of New York residents.
b. The survey suggests that the proportion of California residents who agree that police officers should carry video cameras for the purposes of filming their activities while on duty is 85%.
c. Of the California residents surveyed, 85% agree that police officers should carry video cameras for the purposes of filming their activities while on duty, but this is not strong enough evidence to conclude that the proportion of California residents who agree is significantly different from the proportion of New York residents.
d. This survey suggests that 88% of California residents surveyed agree that police officers should carry video cameras for the purposes of filming their activities while on duty.
