Objective 2.14 or 2.17 Edmonds Community College's (EDCC) scholarship fund received a gift of $ 425,000.
The money is invested in stocks, bonds, and CDs.
CDs pay 2% interest, bonds pay 5.8% interest, and stocks pay 12% simple interest.
To better secure the total investment EDCC invests 4 times more in CDs than the sum of the stocks and
bonds investments
If the annual income from the investments is $13,590 , how much was invested in each vehicle?
solve by the method of your choice either using reduced row echelon form or the matrix equation. Round
answers to the nearest thousand. EDCC invested

In this problem, we explore the effect on the standard deviation of multiplying each data value in a data set by the same constant. consider the data set 14, 6, 8, 15, 15. (a) use the defining formula, the computation formula, or a calculator to compute s. (round your answer to one decimal place.) s = 4.28 (b) multiply each data value by 3 to obtain the new data set 42, 18, 24, 45, 45. compute s. (round your answer to one decimal place.) s = 12.83 (c) compare the results of parts (a) and (b). in general, how does the standard deviation change if each data value is multiplied by a constant c? multiplying each data value by the same constant c results in the standard deviation remaining the same. multiplying each data value by the same constant c results in the standard deviation being |c| times as large. multiplying each data value by the same constant c results in the standard deviation increasing by c units. multiplying each data value by the same constant c results in the standard deviation being |c| times smaller. (d) you recorded the weekly distances you bicycled in miles and computed the standard deviation to be s = 3.8 miles. your friend wants to know the standard deviation in kilometers. do you need to redo all the calculations? yes no given 1 mile ≠1.6 kilometers, what is the standard deviation in kilometers? (enter your answer to two decimal places.)
