Ascientist has two colonies of bacteria, a and b. colony a has 6.6*10^7 bacteria. colony b has 33. the number is colony a is how much more than colony b

How do you find principle and simple interest

If y varies directly as x2 and y=6 when x=6, find the constant of variation.

On a certain portion of an experiment, a statistical test result yielded a p-value of 0.21. what can you conclude? 2(0.21) = 0.42 < 0.5; the test is not statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 21% of the time, so the test is not statistically significant. 0.21 > 0.05; the test is statistically significant. if the null hypothesis is true, one could expect to get a test statistic at least as extreme as that observed 79% of the time, so the test is not statistically significant. p = 1 - 0.21 = 0.79 > 0.05; the test is statistically significant.
