Last year's budget for the legislative branch of a certain government was \$4926 million, and this year it is \$5316 million. Consider last year's budget of \$4926 million to be the reference value. Complete parts (a) through (d) below. a. What is the absolute change in the budget from last year to this year?
b. What is the relative change in the budget from last year to this year? The relative change in the budget from last year to this year is
7.9%. (Round to one decimal place as needed.) c. Next year's budget is estimated to be \$5194million. What is the percentage decrease from this year's budget of \$5316 million? The percentage decrease is 2.3%. (Round to one decimal place as needed.) d. If next year's budget is changed so that it is 88% less than this year's budget of \$5316 million, what is the amount of next year's budget?
(Type an integer or a decimal.) Assume that a statistics professor has a height of exactly 185.3 cm. Assume that this height is measured with a tape measure that can be read to the nearest mm (or 1/10 cm) and results from two different measurements are reported as 185 cm and 186.0 cm. Which measurement is more precise? Which is more accurate? Explain . Identify which measurement is more precise, and explain why. A.The measurement of 186.0 cm is more precise, because it has more decimal places. B.The measurement of 186.0 cm is more precise, because it is nearer to the true value. C.The measurement of 186.0 cm is more precise, because it uses a better measurement method. D.The measurement of 185 cm is more precise, because it is nearer to the true value. E.The measurement of 185 cm is more precise, because it uses a better measurement method.
Identify which measurement is more accurate, and explain why.
