In a long random sequence of A, C, G, or U, how often should a stop codon appear? Group of answer choices 3/64 almost never 1/64 1/3
Find the equation of the tangent line to the curve y^3-3xy^2+cos3xy at the point (0,1). See Example 3 page 132 for a similar example.
Contractionary fiscal policy: increases aggregate demand. increases long-run aggregate supply. decreases aggregate demand. decreases long-run aggregate supply.
Jeni always waits until her gas tank is nearly empty before refueling. She keeps track of the distance she drives on each tank of gas. The distance varies depending on the weather and the amount she drives on the highway. The distance has a mean of 520 km and a standard deviation of 14 km. a) Sketch a normal curve to show the distribution of the driving distances for a tank of gas. Mark the kilometers driven for values that are 1, 2, and 3 standard deviations from the mean. b) What percent of the time does Jeni drive between 492 km and 520 km on a tank of gas?
A 50mH inductor, a 0.2 micro-Farad capacitor, and a 200 Ohm resistor are connected in parallel in the circuit shown. a) Find the roots of the characteristic equation that governs the voltage v shown. b) Will the response be overdamped, underdamped or critically damped? c) Repeat a for R = 312.5 Ohms d) What values of R cause the response to be critically damped? Ans: (a) $s_1 = -5000 \text{ rad/s } s_2 = -20,000 \text{ rad/s }$ (b) Overdamped (c) $s_1 = -8000 + j6000 \text{rad/s}$; $s_2 = -8000 - j6000 \text{rad/s}$ (d) R = 250 Ohm

Question 5 0 / 1 pts Find the indicated probability. Give your answer as a simplified fraction. A study was recently done that emphasized the problem we all face with drinking and driving. Four hundred accidents that occurred on a Saturday night were analyzed. Two items noted were the number of vehicles involved and whether alcohol played a role in the accident. The numbers are shown below. What is the probability that it involved alcohol given that an accident involved 3 or more vehicles? Number of Vehicles Involved Did Alcohol Play a Role? 1 2 3 or more Totals Yes 59 91 20 170 No 23 180 27 230 Totals 82 271 47 400 0.050 0.435 0.426 0.118
