Suppose iq scores were obtained from randomly selected twins. for 20 such pairs of people, the linear correlation coefficient is 0.897 and the equation of the regression line is modifyingabove y with caret equals 10.27 plus 0.88 x, where x represents the iq score of the twin born second. also, the 20 x values have a mean of 100.11 and the 20 y values have a mean of 98.1. what is the best predicted iq of the twin born first, given that the twin born second has an iq of 90? use a significance level of 0.05.

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1
