average of -8 and -4 is -6
the point is (-4, -6)
We expect that students who do well on the midterm exam in a course will usually also do well on the final exam. Gary Smith of Pomona College looked at the exam scores of all 346 students who took his statistics class over a 10-year period. The least-squares line for predicting final-exam score from mid-term exam score was γ=46.6 + 0.41x.
Octavio scores 10 points above the clas mean on the midterm. How many points above the class mean do you predict that he will score on the final. (Hint: what is the predicted final-exam score for the class mean midterm score of x-bar?) This is an example of regression to the mean, the phenomenon that gave "regression" its name: students who do well on the midterm will on average do less well on the final, but still above the class mean.)
Using the model equation, the predicted mean score on the final given a score of 10 points above the class mean in the mid term exam is 50.7
The Least - Square Regression equation which models the relationship between midterm and final exam score is :
γ=46.6 + 0.41xx = 10 points ; substitute the value of x = 10 into the regression equation ;
γ=46.6 + 0.41(10)
γ=46.6 + 4.1
γ = 50.7
The number of points above the mean he'll score in the final exam is predicted to be 50.7

1. In the first diagram we simply count the number of squares along the rise and the number of squares along the run as slope equals rise/run
2. we use the slope formula
[tex] \frac{y2 - y1}{x2 - x1} = \frac{ - 2 - 1}{ 1- ( - 1)} = \frac{ - 3}{2} = - \frac{3}{2} [/tex]

A quality control engineer inspects a random sample of 3 batteries from each lot of 24 car batteries that is ready to be shipped. If such a lot contains six batteries with slight defects, what is the probability that the inspector's sample will contain none of the batteries with defects
Answer:
10
Step-by-step explanation:
The probability of getting a sample without any defect is 1 / 6.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of sample
Given that a quality control engineer inspects a random sample of 3 batteries from each lot of 24 car batteries that are ready to be shipped.
Total batteries = 24
Total non-defective batteries = 24 - 6 = 18
Probability = Number of favourable outcomes / Number of sample
Probability = 3 / 18
Probability = 1 / 6
Therefore, the probability of getting a sample without any defect is 1 / 6.

According to a study, 15 out of 50 adults have allergies. What percentage of adults do not have allergies?
Answer:
70% of adults do not have allergies.
Step-by-step explanation:
It states that 35 out of 50 adults do not have allergies. If we turn this into a fraction (35/50), we can then multiply the denominator by 2 to make it 100. We would then also multiply the numerator by 2.
35 x 2 =70
70/100 = .7
.7 is just the decimal form of 70%
The length of a marathon race is 26 miles 385 yards. What is the total length of the marathon
race in yards?
Plz help
Answer:
46,145
Step-by-step explanation:

The total length of the marathon race in yards when the length of a marathon race is 26 miles 385 yards, is 46145 yards.
How to measure the length?Length measurement is the measurement of the size of an object. The units of length measurement are meter, feet, yards etc.
Yards-This unit is used when the size of a small space has to measure, such as length of bed, ladder etc. There are total 1760 yards in one mile.Miles-This is the basic unit of length measurement of size. The size of roads, distance between two cities are measured in miles.The length of a marathon race is 26 miles 385 yards. As there are total 1760 yards in one mile. Thus, the total number of yards in 26 miles is,
[tex]26\times1760=45760[/tex]
Now, he races for 385 yards along with 26 miles. Thus, the length of marathon is,
[tex]45760+385=46145\rm\; yards[/tex]
