Pizza delivery times at Pizza Time are normally distributed with a mean time of 27 minutes and a standard deviation of 3 minutes. Using the empirical rule, approximately what percent of pizzas are delivered between 24 and 30 minutes? Find the enthalpy of neutralization of HCl and NaOH. 87 cm3 of 1.6 mol dm-3 hydrochloric acid was neutralized by 87 cm3 of 1.6 mol dm-3 NaOH. The temperature rose from 298 K to 317.4 K. The specific heat capacity is the same as water, 4.18 J/K g. A. -101.37 kJ B. -7.05 kJ C. 7055 kJ D. 10,1365 kJ Carbon 14 is an unstable isotope of carbon that decays very slowly. Compared to the common, stable carbon 12 isotope, carbon 14 has two additional ____________.(a) electrons(b) neutrons (c) protons(d) ions Men have XY (or YX) chromosomes and women have XX chromosomes. X-linked recessive genetic diseases (such as juvenile retinoschisis) occur when there is a defective X chromosome that occurs without a paired X chromosome that is not defective. Represent a defective X chromosome with lowercase x, so a child with the xY or Yx pair of chromosomes will have the disease and a child with XX or XY or YX or xX or Xx will not have the disease. Each parent contributes one of the chromosomes to the child. Complete parts a through d below. a. If a father has the defective x chromosome and the mother has good XX chromosomes, what is the probability that a son will inherit the disease? 0.333 What were some of the founding fathers' concerns with the inclusion of a "Bill of Rights"? What is an appeal to authority?A. An appeal to show that a higher power supports the ideaB. An appeal to show that an argument is morally justC. An appeal to show that an argument is reasonably soundD. An appeal to influence a readers feelings 6. Walking is not the most exciting form of exercise a person can take on for fitness. Yet it is low impact and requires no fancy equipment. That makes walking a simple activity for those new to exercise. Walking is less likely than other exercises to cause injury to leg tendons and muscles. All it requires is a good pair of sneakers-no cables, stylish outfits, or weights required. Of course, a person could increase the benefit of a workout by adding weights or speed walking.Which of the following statements supports the main idea in this paragraph? (5 points)a) Walking is boring.b) Walking has a low risk of injury.c) Walking requires sneakers in good condition.d) Walking is too easy for those who exercise regularly. Verify that the function satisfies the three hypotheses of Rolle's Theorem on the given interval. Then find all numbers c that satisfy the conclusion of Rolle's Theorem. (Enter your answers as a comma-separated list.) f(x) = x3 x2 12x + 7, [0, 4] A scientist mixes water (containing no salt) with a solution that contains 35% salt. She wants to obtain 175 ounces of a mixture that is 20% salt. How many ounces of water and how many ounces of the 35% salt solution should she use? 5. After a signal is transmitted from the eyes through the optic nerve, which part of the brain processes thevisual information?LA. The frontal lobeB. The occipital lobeC. The limbic lobeD. The temporal lobe The acceleration of a particle is given by a = ks2 , where a is in meters per second squared, k is a constant, and s is in meters. Determine the velocity of the particle as a function of its position s. Evaluate your expression for s = 5 m if k = 0.1 m1 s2 and the initial conditions at time t = 0 are s0 = 3 m and v0 = 10 m /s One-third of Sharon's land hasfarm animals. One-fifth of the farmanimals are chickens. Whichmodel shows what fraction ofSharon's land has chickens? What is internal recruitment ? The equilibrium constant, Kc, is calculated using molar concentrations. For gaseous reactions another form of the equilibrium constant, Kp, is calculated from partial pressures instead of concentrations. These two equilibrium constants are related by the equation Kp=Kc(RT)n where R=0.08206 Latm/(Kmol), T is the absolute temperature, and n is the change in the number of moles of gas (sum moles products - sum moles reactants). For example, consider the reaction:N2(g)+3H2(g)2NH3(g)for which n=2(1+3)=2. Part A:For the reaction 2A(g)+2B(g)C(g) Kc = 55.6 at a temperature of 313 C .Calculate the value of Kp.Express your answer numerically.Part B:For the reaction X(g)+2Y(g)3Z(g)Kp = 3.83102 at a temperature of 119 C .Calculate the value of Kc. A die rolled. The set of equally likely outcomes is {1,2,3,4,5,6}. Find the probability of rolling an odd number. A water trough is 8 m long and has a cross-section in the shape of an isosceles trapezoid that is 20 cm wide at the bottom, 80 cm wide at the top, and has height 60 cm. If the trough is being filled with water at the rate of 0.3 m3/min how fast is the water level rising when the water is 30 cm deep? During which prehistoric age did humans societies begin farming?A-Neolithic B-bronze C-ironD-Paleolithic Delilah copperspoon is a character from which game? Write a journal entry telling why choosing to abstain from having sex is a smart choice for a teenager in 2011. vaccine(vak-SEEN) an injection given to prevent a specific illness. Its usually made from a very weak version of the organism that causes the disease, so the human body can learn to fight it off.The problem is that we dont have a vaccine for this disease.quarantine(KWOR-uhn-teen) the act of keeping people who might become sick away from healthy onesWere going to have to put these patients into quarantine.What is another way in which the definition of these vocabulary words could be organized within this text?A.in captionsB.in headingsC.in graphsD.in sidebarsI will make you Brainleist
