299 blown-up balloons; possible explanation: fi rst I found the number of heart-shaped balloons, 5 × 14 = 70. Next, I added that number to the number of round balloons and long balloons, 70 + 144 + 108 = 322 balloons in all. Last, I subtracted the number of burst balloons, so 322 – 23 = 299 balloons left.

Y and x have a proportional relationship, and y = 12 when x = 5. What is the value of y when x = 8?
serious [3.7K]
When x = 8 y = 15

The way to figure this out is to subtract 12 by 5. That’s 7 so there’s a difference of 7 between both of the numbers.

Hope this helped!

For which data set is a linear regression most reasonable?
Oxana [17]

Answer:

The correct option is;

A. A set of nine data pairs with a correlation coefficient r = -0.4

Step-by-step explanation:

In statistical analysis, it is important to make use of an adequate sample size in order to arrive at a valid result. An analysis with a very small sample size can provide misleading results

When performing regression analysis it is generally accepted by researchers that each variable should have at least 10 observations.

Therefore, the data set having nine data pairs with a negative correlation of -0.4 will provide the most valid result that can then be used for generalization about the larger statistical population.
