There are two isotopes of an unknown element, X-19 and X-21. The abundance of X-19 is 14.29%. A weighted average uses the percentages of each isotope to scale their contribution to the total mass. Each isotope's contribution is the percentage (in decimal form) multiplied by the mass of the isotope. What is the contribution (in amu) to the weighted average from the X-19 isotope, which has a mass of 19.00 amu?
While each of us has had a reading of our blood pressure taken, many of us may not know what blood pressure actually means. Blood pressure is expressed as a ratio of the maximum (systolic) and minimum (diastolic) pressure found in the aorta during one cardiac cycle. These pressure values are measured in millimeters of mercury (mmHg). Determining abnormal blood pressure is critical for diagnosing and averting a number of serious health problems (e.g. heart disease and stroke). Doctors therefore make decisions about the potential for serious health problems based on a few simple calculations. One simple calculation of interest is pulse pressure (PP). The pulse pressure of an individual can be computed as the difference between the systolic and diastolic pressures. Create a Java class file called PulsePressureIST140. This program will compute a user's pulse pressure based on two inputs: the systolic pressure (a int value) and the diastolic pressure (an int value). Once the input is…

Doctors therefore make decisions about the potential for serious health problems based on a few simple calculations. One simple calculation of interest is mean arterial pressure (MAP). The mean arterial pressure is the average pressure during the cardiac cycle. The MAP of a normal, resting heart can be computed by the formula: MAP = DP + (1/3)PP where DP is the diastolic pressure and PP is the pulse pressure. Create a Java class file called MeanArterialPressure. This program will compute a user's mean arterial…
One way to determine how healthy a person is by measuring the body fat of the person. The formulas to determine the body fat for female and male are as follows: Body fat formula for women: A1 = (body weight x 0.732) + 8.987 A2 = wrist measurement (at fullest point)/3.140 A3 = waist measurement (at navel) x 0.157 A4 = hip measurement (at fullest point) x 0.249 A6 = forearm measurement (at fullest point) x 0.434 B = A1 + A2 A3 A4 + A5 Body fat = body weight - B Body fat percentage = body fat x 100/body weight Body fat formula for men: A1 = (Body weight x 1.082) + 94.42 A2 = wrist measurement x 4.15 B = A1 A2 Body fat = body weight B Body fat percentage = body fat x 100/body weight Write a program to calculate the body fat of a person.
using matlab You measure the temperature of coffee cooling in a porcelain mug at room temperature (68°F) at various times. The data follows: Time t (sec) Temperature T (°F) 0 145 620 130 2265 103 3482 90 Develop a model of the coffee’s temperature as a function of time and use the model to estimate how long it will take the temperature to reach 120°F
The square root of any number N>0 can be opproximated by repeated calculation using the formula N = squared_value NG = 0.5 (FG + N/FG) where NG stands for next guess and FG stands for first guess. The value of NG and FG are compared. If the two values are comparably close, then NG is the final answer. If the two values are off, NG becomes FG and the formula is used again to compute FG. After so many iterations, NG and FG will merge. a. Write a function that calculates the square root of a number using this method. The initial guess wilI be the starting value of FG (FG = 1). The function will compute a value for NG using the formula given and returns that value. (Change the name of the functions to something more meaningful) double fun_1 (double FG, double N); b. Write a function that prompts the user for any number N > 0, and returns that value back. The prototype is like follows: double fun_2 ( void ); Now inside the main function, check the difference between NG and FG to see whether…
The ACT is a standardized test used by college admissions offices as a factor in whether an applicant is or is not admitted to their college. Since so many students take this test each year, the distribution of results are typically approximately normal.

Question Harry has a big wall clock, that got hit while he was playing. Now, the minute hand doesn't rotate by the angle 2t/3600 each second, but now it moves according to different angle x. You can assume that coordinates of the centre of the clock are (0, 0) and the length of the minute hand is I. One endpoint of the minute hand is always located at the clock centre; the other endpoint is initially located at the point (0, 1). One second later, Harry observes that this endpoint is at distance d above the x-axis, i.e., the y-coordinate of this endpoint is equal to d. Harry is curious about where the minute hand will be (specifically, its y-coordinate) after t seconds. Because t can be very large, Harry can't wait for that moment. Please help him to write a python code that prints a single line containing the output. Input: 422 Output 4
