An unknown metal has been found and the following experimental results have been tabulated in the table below. The table contains the grams of the unknown metal and the volume in milliliters of water displacement. Find a linear model that express volume as a function of the mass. Round your answers to 3 decimal places grams Volume in ml 13 176.7 15.5 210.7 18 249.6 20.5 278.7 23 309.5 25.5 339.7 28 373 Volume where x is the grams of the unknown metal

Mr. James McWhinney, president of Daniel-James Financial Services, believes there is a relationship between the number of client contacts and the dollar amount of sales. To document this assertion, Mr. McWhinney gathered the following sample information. The x column indicates the number of client contacts last month and the y column shows the value of sales ($ thousands) last month for each client sampled. Sales ($ thousands), y Number of Sales ($ Contacts,X thousands),y Number of Contacts,x 14 24 23 30 12 14 48 90 20 28 50 85 16 30 55 120 46 80 50 110 E Click here for the Excel Data File a.

A trough is 10 feet long and 2 feet across the top. It's sides are isosceles triangles with altitudes of 2.5 feet. If water is being pumped out of the tank at a rate of 5 cubic feet per second, find the following:  find the rate, in feet per second, at which the water level is changing at the instant the water level is at 1.25 feet. In ft/s

I need help finding/rounding height to the nearest CM and same with weight in KG Thanks so much!!

Use the estimated regression equation to predict the total time to produce the order of size 240. Round to 2 decimals.

Shortleaf Pines. The ability to estimate the volume of a tree based on a simple measurement, such as the diameter of the tree, is important to the lumber industry, ecologists, and conservationists. Data on volume, in cubic feet, and diameter at breast height, in inches, for 70 shortleaf pines was reported in C. Bruce and F. X. Schumacher’s Forest Mensuration (New York: McGraw-Hill, 1935) and analyzed by A. C. Akinson in the article “Transforming Both Sides of a Tree” (The American Statistician, Vol. 48, pp. 307–312). The data are provided on the WeissStats site. a. obtain and interpret the standard error of the estimate. b. obtain a residual plot and a normal probability plot of the residuals. c. decide whether you can reasonably consider Assumptions 1–3 for regression inferences met by the two variables under consideration.

The following formula gives the relationship between the thoracic mass of the butterfly and its mean forward airspeed. V(m) = 17.6 Vm3 where v(m) represents the mean forward airspeed in meters per second of a butterfly with a thoracic mass of m grams. (Round your answers to the nearest hundredth of a gram. Include units in your answers. More information.) (a) Use the model to estimate the thoracic mass of a butterfly that can fly at 8 meters per second. (b) Use the model to estimate the thoracic mass of a butterfly that can fly at 9.5 meters per second.
