Four test tubes with 20mL of water and cut flowers were set up. Three of the test tubes had food coloring added. You observethe flowers that were placed in the test tubes for the following five days. You record your observations each day at 10:00am.On the fifth day, the flowers in the colored test tubes began to turn the color of the liquid in which they were placed.You hypothesis was: IF cut flowers are placed in colored water, THEN the flower petals will absorb that color throughout thepetals.Experimental DesignIn this experiment, the independent variable was:O The test tube without food coloringO 10:00amO The color of the waterO The ending color of the flowers24 2526 272829 30 31 32 33Help Center | Schoology Blog I PRIVACY POLICY I Terms of Useto searchDELL

(1). The ending color of the water is a dependent variable because it depends upon the color of the…

According to a survey, 85% of American adults eat salad at least once a week. A nutritionist suspects that the percentage is higher than this. She conducts a survey of 200 American adults and finds that 171 of them eat salad at least once a week. Conduct the appropriate test that addresses the nutritionist's suspicion. Use an a = 0.05 level of significance. State the null and alternative hypothesis: What parameter are we testing? Ho: H₁: Assumptions: SRS, n < 0.05N, npo (1 - po) By hand, test statistic is (Round to 5 decimals): P-value. Round to 4 decimals: Conclusion: There is (enter sufficient or insufficient) evidence at the a = 0.05 level of significance to conclude that the percentage of adult Americans that eat salad at least once a week is ("equal to" or "higher than" or "less than" or "not equal to") 85%.
an artifact is dug out of the ground on a greek island and the archeolgist want to determine the type of material it is made of they have a tape measure and a scale that measures mass density instead of mass. they measure the three sides of the artifact to be 1.25mm 2.75mm 3.45mm and mass density of 79.4g/cm^3 what is the mass of the material in grams?

A group collected data in an experiment to learn to draw suitable trendline in a graph. They don't know the theoretical model, so they are trying to determine one through this experiment. They used Excel to display the data and to find good fit. They tried linear, exponential, and power trendlines. The result of each trial is shown below. The title of the plot contains the name of the trendline used to fit. What should be their analysis based on the result they have so far? Exponential trendline 20 Power trendline 18 y = 0.8374e047x R? = 0.9851 16 y = 0.8045x1.538.

8.36 grams of a mystery substance of food with a molar mass of 149.36 g/mol is burned in a bomb calorimeter. The water in the bomb calorimeter absorbs 105,961 Joules from the burning of the substance. Calculate the heat of combustion of the mystery substance in kJ/mol. (Please input your answer as a negative number.) (DO NOT PUT UNITS IN YOUR ANSWER.) Assume that all of the heat lost by the substance is transferred to the water and no heat is lost to the surroundings.
