1) High temperatures in a certain city for the month of August follow a uniform distribution over the interval 65°F to 87°F. What is the probability that a randomly selected August day has a high temperature that exceeded 70°F? A) 0.2273 B) 0.7727 C) 0.4605 D) 0.0455 SHORT ANSWER. Write the word or phrase that best completes each statement or answers the question. 2) You are performing a study about the weight of preschoolers.
3.) First, let’s find the slope from point A to point B. m=0-3/-3-0. This equals -3/-3, which reduces to positive 1. Now, we can use point-slope form. I will use point B and it would look like this: y-(0)=1(x-(-3)).

A company issued a 30-year, $1,000 par value bond that has 10.85% coupon rate. Coupons are paid out semi-annually and the relevant interest rate is 9% compounded semiannually. a. (3 points) What was the value of this bond when it was issued? PMT = (.1085/2)*1000=54.25 N = 60 R = 0.09/2=0.045 (or 4.5 for calculator purposes) FV = 1000 PV =?
Husky used annual observations from 20 prior years to estimate each of the four equations. Following are a definition of the variables used in the four equations and a statistical summary of these equations: St = Forecasted sales in dollars for Lockit in period t St–1 = Actual sales in dollars for Lockit in period t – 1 Gt = Forecasted U.S. gross domestic product in period t Gt–1 = Actual U.S. gross domestic product in period t – 1 Nt–1 = Lockit’s net income in period t – 1 Required: 1. Write Equations 2 and 4 in the form Y = a + bx. 2. If actual sales are $1,500,000 in 2009, what would be the forecasted sales for Lockit in 2010?
1. Assume that a radiologist group practice has the following cost structure: Fixed costs: $500,000 Variable cost per procedure $25 Charge (revenue) per procedure $100 Furthermore, assume that the group expects to perform 7,500 procedures in the coming year. a. Construct the group’s base case projected P & L statement Total revenue ($100 x 7,500) = $750,000 Total variable cost ($25x7500) =$187,000 Fixed cost=$500,000 Total rev-total var cost-fixed cost=profit 62,500 b. What is the group’s contribution margin? What is the breakeven point?
What does this result mean? The t ratio of -0.65 represents the smallest relative difference between the pretest and 3 months outcomes. This ratio does not have an asterisk next to it in the table which according to the footnotes the asterisk is said to represent p < 0.05 the least stringent acceptable value for statistical significance. 4. What are the assumptions for conducting a t-test for dependent groups in a study?
Graded Assignment Practice: You Do the Math Answer the following questions to learn more about wages and income levels in the United States. 1. Calculate the hourly wage associated with the two annual income levels listed below. Assume that an individual works 40 hours per week for 50 weeks each year. (5 points) Annual income Hourly wage 2005 U.S. federal poverty line for a family of four $19,350 $9.675 2005 U.S. median household income $46,326 $23.163 2.
Loss: $3000 - $2000 = $1000 * F = $ 1000 5000 = $0.2 = 20 cents/bushel * F2= $450 + $ 20 = $470 b. Under what circumstance could $1500 be with-drawn from the margin account? F = 15005000 = $ 0.3 = 30 cents F2 < F1 => F2 = F1 – 30 cents = 450 cents – 30 cents = 420 cents Exercise 4.28: The 6-month, 12-month, 18-month, 24-month zero rates are 4%, 4.5%, 4.75% and 5% with semiannual compounding. a. What are the rates with continuous compounding?
