Form the interval, y = 2s. d. According to Chebychev's Rule, what proportion of sample observations will fall within the interval, part c? e. According to the Empirical Rule, what proportion of sample observations will fall within the interval, part c? f. Determine the actual proportion of sample observations that fall within the interval, part c.

help please!! I am very confused :( If someone can answer (with explanations) thank you!! A long time ago, in a galaxy far, far away there was a civilization that enjoyed making gigantic flans and watching them collide in the sky. During one of such experiment they constructed two flans and positioned them in the sky as indicated in the diagram. Flan 1 has mass 𝑚1=5.0∗1021𝑘𝑔 and position 𝑟⃗ 1=〈2.0∗105,4.0∗105,0〉𝑚 Flan 2 has mass 𝑚2=2.0∗1021𝑘𝑔 and position 𝑟⃗ 2=〈9.0∗105,4.0∗105,0〉𝑚 a) Calculate the unit vector 𝑟̂ that points from flan 2 to flan 1. b) Determine the magnitude of the gravitational force on flan 2 due to flan 1. c) Calculate the gravitational force (a vector) on flan 2 due to flan 1. d) Both flans started from rest at their given locations. Predict the velocity of flan 2 in one time step Δ𝑡=14400 seconds later:

A module on the microcontroller is configured using a control register called CTL that has the format shown below. SLP 2- CLK 3- CAP 2- IE 1- SLP: selects sleep mode; value between 0 and 3 CLK: selects clock speed; value between 0 and 7 CAP: selects built-in capacitor value; choice between 0 and 3 IE: interrupt enable bit (1: enable/ O: disable) To support programming the device, the environment has declared the symbolic constants: SLP_3: 1100 0000 SLP 2: 1000 0000 SLP_1: 0100 0000 SLP_O: 0000 0000 CLK_7: 0011 1000 CLK_6: 0011 0000 CLK_0: 0000 0000 CAP_3: 0000 0110 CAP_O: 0000 0000 IE_1: 0000 0001 IE_0: 0000 0000 Perform all the operations below using the masks defined above. a) Write a line of code that configures the module as the following: (Sleep mode 1) (Clock speed 5) (Capacitor value 2) (Interrupts enabled). b) For the operation above, show the masks used and the final value of CTL in hexadecimal format. c) Write a piece of code that changes SLP to 2. The current value of SLP is unknown. d) Write a piece of code that changes CLK to 6. The current value of CLK is unknown. e) Write an if-condition line that checks if SLP-2. Write an if-condition line that checks if CLK-6. B) Write an if-condition that checks if the current value of CLK is either of (0, 2, 4, 6).

Scientists can track the movement of proteins through the endomembrane system using an approach known as a pulse-chase experiment. This experiment involves • the "pulse" phase: Cells are exposed to a high concentration of a radioactively labeled amino acid for a short period to tag proteins that are being synthesized. • the "chase" phase: Any unincorporated radioactively labeled amino acids are washed away and large amounts of the same, but unlabeled, amino acid are added. Only those proteins synthesized during the brief pulse phase are radioactively tagged. These tagged proteins can be tracked through the chase period to determine their location in the cell. The data below were obtained from a pulse-chase experiment in which cells were examined at different times during the chase period. The numbers represent the radioactivity (measured in counts per minute) recorded at each of the indicated sites. The higher the number, the greater the radioactivity ER 162 Time 3 minutes 20 minutes 60 minutes 73 Golgi Cytoplasm Lysosomes Extracellular space 7 21 5 4 88 17 10 8 35 14 112 13 23 18 151 10 9 120 minutes 11 Based on these data, what of the following is the most likely function of the cells in this experiment?
