DSS The cube root of 64 is 4. How much larger is the cube root of 64.6? Estimate using the Linear Approximation. (Give your answer to five decimal places.) A survey asked families with 1, 2, 3, or 4 children how much they planned to spend on vacation this summer. The data collected by the survey are shown in the table.What is the probability that a family with 3 children is budgeting to spend more than $3,000 on vacation? Round your answer to the nearest hundredth, like this: 0.42 (Its not B)A. 0.30B. 0.19 (not this one)C. 0.06D. 0.26 The average value, 1, of a function, f, at points of the space region is defined as 7 *S][v fdy, where w is the volume of the region. Find the average distance of a point in solid ball of radius 29 Given f(8)=4f8=4, f(8)=6f8=6, g(8)=1g8=1, and g(8)=7g8=7,find the values of the following.(fg)'(8)=(f/g)'(8)= XYZ Bank lends $20,000,000 to ABC Corporation which has a credit rating of BB. The spread of a BB rated benchmark bond is 2.5 percent over the U.S. Treasury bond of similar maturity. XYZ Bank sells a $20,000,000 one-year credit forward contract to IWILL Insurance Company. At maturity, the spread of the benchmark bond against the Treasury bond is 2.1 percent, and the benchmark bond has a modified duration of 4 years. What is the amount of payment paid by whom to whom at the maturity of the credit forward contract? Find the area A of the triangle whose sides have the given lengths.

What number of moles of oxygen would exert a pressure of 10 atom at 320k in a 8. 2dm3 cylinder 1- A researcher examines whether student's choice of enrolling in a summer Math class is influenced by students reading an article on the growth mindset. Half the students read the article and half did not.A. The independent variable is students reading an article on the growth mindset.B. The independent variable is a categorical independent variable as it involves two categories.C. The dependent variable in this research is"students' choice of enrolling in the summerMath class."D. There are two levels for the independent variable.E. The scale of measurement for the dependent variable is nominal.2- A researcher examines whether scores on a Statistics final exam (0 points to 100 points) are influenced by whether background music is soft, loud, or absent. (Note: Assume the students have been successfully completing quizzes up to the final exam.)A. The independent variable in this study is the background music (soft, loud, or absent).B. The independent variable is categorical.C. The dependent variable in this study is the scores on the Statistics final exam. D. There are three levels for the independent variable.E. The scale of measurement for the dependent variable is an interval scale.3- A researcher compares freshmen, sophomores, juniors, and seniors with respect to how much fun they have while attending college (scale: 0=no fun at all, 1, 2, 3, 4, 5, 6 to 7=maximum amount of fun). (Note: Assume equal intervals in the scale and a true zero point.)A. The independent variable is the students: freshmen, sophomores, juniors, and seniors.B. The independent variable is categorical.C. The dependent variable in this study is the level of fun experienced by the students while attending college.D. There are four levels for the independent variable: freshmen, sophomores, juniors, and seniors.E. The scale of measurement for the dependent variable is nominal.4- A researcher examines whether taking Vitamin D supplements (0x a day, 1x a day) influences self-reported depression (measured as either depressed or not depressed).A. The independent variable is the frequency of taking Vitamin D supplements.B. The independent variable is categorical.C. The dependent variable is self-reported depression (measured as either "depressed" or "not depressed").D. There are two levels for the independent variable: Ox a day and 1x a day.E. The scale of measurement for the dependent variable is nominal.BONUS A researcher examines whether being in a room with blue walls, green walls, red walls, or beige walls influences aggressive behavior in a group of adolescents. The adolescents are given simulated, electronic games where they are required to administer shocks. The researcher will then rank the results of the room where the most shocks occurred (1st, 2nd, 3rd, and 4th).A. The independent variable is the color of the room walls.B. The independent variable is categorical.C. The dependent variable is the number of shocks administered.D. There are four levels for the independent variable.E. The scale of measurement for the dependent variable is nominal.Teacher asked to do it without explanation Write an algorithm (pseudo-code) that takes an unsorted list of n integers and outputs a sorted list of all duplicate integers. There must be no duplicates in the output list, also the output list should be a sorted list. The algorithm must run in O(n) time. Show your analysis of the running time. Note: Assume that inputs are integer values from 0 to 255.
