On January 1 Carol Farmer and Jim Romans formed a partnership, Research Consultants. Each partner invested $50,000 in cash on that date. The partnership agreement stated that the partners would share net income or loss equally. During the year Farmer invested an additional$2,000 and withdrew $7,500 for personal use. Romans invested an additional$1,500 and withdrew $8,500. Net income for the first year was$33,176. In your working papers, prepare a statement of changes in partners’ equity for the year ended December 31.

Find all interior angles of a triangle, using the given the ratios among them. Angles' ratio: 3:4:5

Find the first seven terms of the Maclaurin expansion of $f(z)=\sin ^{2}(z)$ in four ways, as follows. (a) First, compute the Taylor coefficients at 0. (b) Find the first seven terms of the product of the Maclaurin series for sin(z) with itself. (c) Write $\sin ^{2}(z)$ in terms of the exponential function and use the Maclaurin expansion of this function. (d) Write $\sin ^{2}(z)=(1-\cos (2 z)) / 2$ and use the Maclaurin expansion of cos(z).

In his book Outliers, author Malcolm Gladwell argues that more American-born baseba]] players have birth dates in the months immediately following July 31 because that was the age cutoff date for nonschool baseball leagues. The table below lists month of births for a sample of American-born basebal l players and foreign-born baseball players. Using a 0.05 significance level, is there sufficient evidence to warrant rejection of the claim that months of births of baseball players are independent of whether they are born in America? Do the data appear to support Gladwell 's claim?

Make a table that lists the characteristics of seedless vascular plant groups.

Members of a certain club are required to register for one of three games: badminton, table tennis or darts. The number of club members of each gender choosing each game in a particular year is shown in the table.

$$\begin{matrix} \text{ } & \text{Badminton} & \text{Table tennis} & \text{Darts}\\ \text{Male} & \text{37} & \text{16} & \text{28}\\ \text{Female} & \text{32} & \text{10} & \text{19}\\ \end{matrix}$$

Use a chi-squared test, at the 5% significance level, to test whether choice of game is independent of gender. State clearly the null and alternative hypotheses, the expected values and the number of degrees of freedom.

Jose started at his home, H(0, 0) and walked to a park located at P(4, 2). He then went to Jacintha's house located at F(8, 0). Later, he walked straight home. If each unit on the coordinate plane represents 50 feet, what is the distance that Jose walked, to the nearest foot?
