Question It is a known fact that 50% of all Americans are male. A researcher wants to see if the percent of business owners who are male is greater than the percent of all Americans who are male. The researcher should use Ho:p1=p2, Ha:p1>p2 for the null and alternative hypotheses. True or false?

Determine the effective annual yield for $1 invested for 1 year at 7.5% compounded quarterly. The effective annual yield is %. (Round to the nearest hundredth.)

C+ Q1. The Students' Corner Store in a university needs a program to implement its students' discount policy. The program is to prompt the user to enter the purchase total and to indicate whether the purchaser is a student. Students are eligible to receive a 20% discount on all their purchases. The discount calculation, however, must be done before addition of the 5% sales tax. This is done to ensure that the discount is not applied to the sales tax. Here are two sample output files - one for a student purchaser and one for a nonstudent purchaser. Total purchases: $ 122.00 Student's discount (20%2:24.40 Discounted total: 97.60 Sales tax (5%): $ 102.48 Total purchases: $ 24.90 Sales Tax (5%): 1.25 Total: $ 26.15

THANKS A MELON FOR MAKING MY BIRTHDAY SPECIAL! 1. A concrete column 4.30 m high with a cross-sectional dimension of 20 cm x 25 cm is resting on a concrete footing 30 cm thick x 80 cm square. If class "B" concrete is specified, find the quantity of cement, sand, gravel, and water if there are 12 columns of the same size. Use 40 kg / bag cement. Water-cement ratio is 50%. 2. Prepare bill of materials for the masonry works using CHB. Use 40 kg/bag cement - class "B" for concrete and class "C" for mortar and plastering. Take note that only the outer part of the wall will be plastered. 0.35 m. 0.70 m. 1.00 m. 0.50 m. W-2 1.20 m. 3.00 m. 1.20 m. 0.70 m. B В A 2.70 m. 2.10 m.

Shown in the figure below is a capacitor. Each plate has an area of A = 1.4e-02 m2 and has a gap d = 6.6e-04 meters. Att filled with a dielectric of constant K = 3.87. The thickness of the dielectric layer is a = 2.64e-04 meters leaving a free space Empty Capacitor Partly Filled Capacitor Area = A dielectric constant K d Write the FORMULA for the capacitance of the empty capacitor. 1 Determine the capacitance of the empty capacitor Cempty = Farads When you partly fill the capacitor, which of these best describes the new configuration: Parallel Series Both series and parallel Neither series nor parallel e-02 m2 and has a gap d = 6.62-04 meters. At the first moment, the capacitor is empty. At the second moment is it partly ayer is a = 2.64e-04 meters leaving a free space of b = 3.96e-04 meters. dielectric constant Farads - configuration: Determine the formula for the partly filled capacitor Chilled = Determine the value of the partly filled capacitor Chilled = Farads NOTE: Decide whether the partly filled capacitor acts like parallel or series by following the charge: . If the charge splits between the caps, parallel. • If the charge is the same on both caps, series, • The formula for the filled capacitor should use only the distances a and b (NOT d).
