Answer:
The Regression line is that line , which passes through all the points , through a single point , or none of the points.
Here, the table is about ,weight of a dog in pounds at various ages in months.
The ratio of Weight at different stages,of months should be proportional.
So, if you look at option (1) , the ratio of x to y in three cases are same that is
It means Regression line is Passing through three points, means Dog's weight at three different stages of month are same.and in other tables the ratio are not equivalent.
So, Table 1, that is option 1
is true.
x: 3, 4, 6, 8, 9, 12
y: 2, 5, 7, 10, 11, 15
Answer:
About 276,500 country A students studied abroad during the 2012-2013 school year.
Step-by-step explanation:
Given that in the 2012-2013 school year, approximately 790,000 foreign students studied in country A, and the number of country A students who studied abroad that same year was about seven-twentieths of the number of foreign students who studied in the country A, to find the number of country A students who studied abroad during the 2012-2013 school year, the following calculation must be performed:
790,000 x (7/20) = X
790,000 x 0.35 = X
276,500 = X
Therefore, about 276,500 country A students studied abroad during the 2012-2013 school year.
Answer:
<h2>1. (52 - 2) (1 + 1) = 100</h2><h2>2. (12 - 2) (9 + 1) = 100</h2><h2>3. (6 - 2) (24 + 1) = 100</h2><h2>4. (3 - 2) (99 + 1) = 100</h2><h2>5. (102 - 2) (0 + 1) = 100</h2>

Answer:
A and B
Step-by-step explanation:
-7/-2=7/2
A= -(-7/2)
negative and negative are canceled out to make 7/2
B=-7/-2
-7/-2=7/2
Answer:
T=29.95a + 13.95c
Step-by-step explanation:
For this equation let a=amount of adult tickets, c=amount of children tickets, and T=the total cost. Since each adult ticket costs 29.95 dollars that needs to be multiplied by the number of adult tickets to see how much was spent on adults, the same goes for the price and number of children tickets. Finally, both of those totals need to be added together to see how much is spent overall for all of the guests.
