Find the perimeter and area of the shaded sections of these shapes. (i) [7] (ii) [7] Total 60 marks Geometry and trigonometry Solutions to Topic assessment 1. The curve is a circle, centre O and radius 2. [2] 2. Substituting [pic] into [pic] gives [pic] Since the equation has a repeated root, the line meets the circle just once, and so the line is a tangent to the circle.
Using the formula for slope find the slope of the following: 1. (1, 15), (2, 25) 2. (2, 25), (3, 35) 3. (1, 15), (3, 35) 4. (3, 35), (4, 45) Assume that the total cost is a linear function of the number of packages ordered.
TASK 1 A. Complete the attached “Simulation Template” to determine the following costs: 1. Average materials cost per unit The first thing I had to do was figure out the random numbers interval in order to figure out the material cost per unit. Materials Probability Cost Random Numbers Interval* 0.2 $ 33.00 0.00 < 0 .20 0.33 $ 35.00 0.21 < 0.53 0.37 $ 38.00 0.54< 0.90 0.1 $ 39.00 0.91 < 1 *The random number interval came from the probability which was provided in the simulation template. I first start with 0.00 less than the probability which is 0.20 then we start at 0.21 less than 0.53.

Explain. 17. Reports from a new system set up to monitor Internet use by company employees indicate that 145 out of a random sample of 1100 employees at a corporation accessed internet sites that were clearly not related to their jobs over the last week. On average, employees who accessed non job related sites spent 4.8 hours per week at such sites with a standard deviation of 2.1 hours a. Give a 95% confidence interval for the percentage of employees at the
The SD for N=100: | 0.345 | 8a. Perentile score for 99°F: | 0.89 | 8b. z score for 99° F: | 1.29 | 8c. Is a body temperature of 99.00°F “unusual”? Why or why not?
(b) Since the confidence interval includes 0, the researcher can conclude that the proportion of iPod owners at the two venues may be the same. (c) Since the confidence interval includes 0, the researcher can conclude that the proportion of iPod owners at the two venues is different. (d) Since the confidence interval includes more positive than negative values, we can conclude that a higher proportion of people at the baseball game own iPods than at the rock concert. (e) We cannot draw a conclusion about a claim without performing a significance test. 8.
We did our own unscientific poll on whether those Channel 6 surveys accurately reflect public opinion. The results: a full 100 percent of the respondents say absolutely, positively not.î Is Cuprisinís comment justified? Article Review. Many articles present statistical data and list margins of error (for example, reports on political opinion polls, growth or decline of the housing markets, manufacturing sectors, etc.). Find one such article from a reliable source (such as EBSCO or Proquest) in the online library that includes a construction of confidence intervals for the data studied, and give a summary of the topic and the statistical results presented.
