Explain the difference in these two readings. 8. In the legend beneath Figure 2, the authors give an equation indicating that diastolic blood pressure is DBP = 25.8 + 0.13x. If the value of x is postnatal age of 30 hours, what is the value for Yˆ for neonates ≤ 1,000 grams? Show your calculations.
(Data are from Science 283 [February 26, 1999], p. 1296.) A) What is the probability that a randomly chosen sample of glass will break at less than 579 MPa? z(579) = (579-579)/14 = 0 P(x < 579) = P(z<0) = 0.5000 B) More than 590 MPa? z(590) = (590-579)/14= 11/14= 0.7857 P(x<500) = P(z< 0.7857) = 0.2160 C) Less Than 600 MPa?
Use your line graph from Part II to interpolate, or estimate, atomic radius of Tin (Sn). (1 point) Answer: By using the given line to interpolate the atomic radius of tin, it can be found that its radius is around 149pm. 5. Tin’s actual atomic radius is 140 pm. . Use the math equation below to determine the percent error of your estimated value. (2 points) Percent error = × 100 This equation means that you subtract to find the difference between the actual value (given in this problem) and the experimental value (estimated from the graph).

Determining the mass of the two unknown weights (unknown weight #1 and #2) was determined using only the centigram balance using the weighing by difference method. Unknown weight # 1 had a mass of 24.82 g while unknown weight #2 had a mass of 25.17 g. The average mass experiment was conducted by individually weighing five different copper slugs on an electronic balance, then
The independent variable is the length of the string. The angle of the drop height was at 90 degrees and the mass was 10 grams Length of String (mm) | Trial 1 (seconds) | Trial 2 (seconds) | Trial 3 (seconds) | Average (seconds) | Period (seconds) | 300 mm | 25.15 seconds | 25.26 seconds | 25.12 seconds | 25.18 seconds | 1.259 seconds | 200 mm | 20.70 seconds | 21.15 seconds | 20.78 seconds | 20.88 seconds | 1.044 seconds | 100 mm | 15.61 seconds | 15.60 seconds | 16.03 seconds | 15.75 seconds | 0.7875 seconds | 3.) Mass: Hypothesis: I predict that the greater the mass on the pendulum, the longer period of the pendulum. The independent variable is the mass on the pendulum. The angle of the drop height was at 90 degrees and the length of the string was at 300 mm.
“Density is the mass per unit volume of a material”. (Coordinated Science, pg. 354) By calculating the density of post 1983 pennies, we can compare it to the given density values of other metals to find the metal used in the core of a penny. Conclusion The metal used inside post 1983 pennies is zinc. We came to this conclusion by calculating the density of post 1983 pennies using the equation; massvolume=density.
Each piece weighed on a very accurate scale. The results in grams were: 3.087 3.131 3.241 3.241 3.270 3.353 3.400 3.411 3.437 3.477 a. Construct a 90 % confidence interval for the true mean weight. b. What sample size would be necessary to estimate the true weight with an error of + or – 0.03 grams with a 90% confidence. c. Discuss the factors which might cause variation in the weight of Tootsie Rolls during manufacture.
BMI=25.96 this is what I came up with as my BMI figure in the Kg/Meters. “One Kilogram equal 2.2 Lbs and 1 inch equal .0254 meters”. To convert your height by to inch 1 foot =12 inches: 5 foot *12 inches = 60 inches that is how you come up with the inches. Pounds to Kilograms: 132.50 lbs/2.2 =60.227 kgs which basically means 132.50 is equivalent to 60.227 kilograms. To figure out if your over weight do the formula just like I did above and if you are: •
