Clara is a vegan and she does not drink milk, a food advertised as a best source of calcium. but she is not worried too much since she knows that leafy greens and legumes are excellent sources of this mineral. what percentage of clara’s daily calcium needs is in a cup of cooked collard greens? the food label says it is 27% dv. in your calculations, use fractions (decimal equivalents, not the percentages); for example, for 25%, insert 0.25. for the final answer use a percentage and round the answer to the nearest whole number.

6x + 3y = -6 2x + y = -2 a. x = 0, y = -2 b. infinite solutions c. x = -1, y = 0 d. no solution

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.
