Annual high temperatures in a certain location have been tracked for a sample of 14 years. Let X represent the year and Y the high temperature (in C∘). xy320.84421.36520.78618.9718.22818.64917.761018.781116.21215.921314.041417.161515.481615.3 Calculate the correlation coefficient.

H0: There is not a significant relationship between the year and high temperature, i.e., ρ=0. Ha: There is a significant relationship between the year and high temperature, i.e., ρ≠0. Calculate the test statistic. Round to three decimal places. t= Calculate the p-value. Round to four decimal places. p-value =

3. Deline Corp. purchased a new piece of machinery on 1 January 2023. Selected data for the purchase is in the spreadsheet. Required: a. Show calculations for annual depreciation for each year in the life of the equipment using straight-line, double-declining balance, and sum-of-the-years’-digits depreciation methods. b. If Deline sold the equipment at the end of 2025 after depreciation had been recorded, for a selling price of $62,000, what gain or loss would they have recognized on the sale? Show calculations.

Part A MISSED THIS? Watch KCV 15.8, IWE 15.9; Read Section 15.8. You can click on the Review link to access the section in your eText. Consider the reaction CO (g) + H$_2$O (g) $\rightleftharpoons$ CO$_2$ (g) + H$_2$ (g) $K_c$ = 102 at 500 K A reaction mixture initially contains 0.155 M CO and 0.155 M H$_2$O. What will be the equilibrium concentration of CO$_2$? Express the concentration in molarity to two significant figures. [CO$_2$] = M Submit Previous Answers Request Answer Incorrect; Try Again; 5 attempts remaining Use an ICE (Initial, Change, Equilibrium) table to organize the data. Your table should look something like this: [CO] [H$_2$O] [CO$_2$] [H$_2$] Initial 0.155 0.155 0.0 0.0 Change -x -x +x +x Equilibrium - Start by filling in the row for Equilibrium. Then use the law of mass action to determine the equilibrium constant, $K_c$, expression and substitute terms from the table. Solving for $x$ will give you [CO$_2$].
If the range of the data (16, 15, 20, 17, 13, 11) equals to the mean of the data (2, 16, 6, x, 8) then the value of x is
