Manajer perusahaan rokok RAENAK sigaret kretek mesin mendapati bahwa 12% dari produksinya berada di bawah standar produksi (buruk). Pada suatu hari, manajer tersebut mendapatkan laporan bahwa pada hari tersebut didapatkan produk rokok di bawah standar sebesar 17% dari sampel acak sebesar 1000 batang rokok. Ujilah apakah cacat produksi (sebesar 17%) tersebut bersifat random atau permanen (mesin harus diperbaiki)! Gunakan a= 0,05! The manager of the machine-made kretek kretek cigarette company RAENAK found that 12% of its production was below production standards (poor). One day, the manager received a report that on that day 17% of substandard cigarette products were obtained from a random sample of 1000 cigarettes. Test whether the manufacturing defects (17%) are random or permanent (machines must be repaired)! Use a=0.05!
The orbital time of Neptune around the Sun is 165 Earth years and its orbital path is 30 times longer than that of the Earth.
Calculate the orbital speed of Neptune relative to the Earth. orbital speed
State how the speed of travel of Neptune compares with that of the Earth.
Redshift measurements show that a galaxy is moving away from the Earth at the speed of 60000 km/s. Taking the Hubble constant H, as 2.2 x 10-18s¹ and 1 light-year as 10¹3 km, calculate and show your working for:
a)how far the galaxy is from the Earth distance
b)how long it has taken light from the galaxy to reach the Earth
c) the time the galaxy and the Milky Way have been travelling apart
d) Explain the significance of the time you calculated in c part of the question
1. A coil with 25 turns of wire is wrapped around a hollow tube with an area of 1.8 m². Each turn has the same area as the tube. A uniform magnetic field is applied at a right angle to the plane of the coil. If the field increases uniformly from 0.00 T to 0.55 T in 0.85 s, find the magnitude of the induced emf in the coil. If the resistance in the coil is 2.5 , find the magnitude of the induced current in the coil.
2. A coil consists of 200 turns of wire having a total resistance of 2.0. Each turn is a square of side 18 cm, and a uniform magnetic field directed perpendicular to the plane of the coil is turned on. If the field changes linearly from 0 to 0.50 Tin 0.80 s, what is the magnitude of the induced emf in the coil while the field is changing? What is the magnitude of the induced current in the coil while the field is changing?

A company manufactures a new type of mosquito repellents with the period of effectiveness that is approximately normally distributed with a standard deviation of 30 hours. A sample of 40 repellents was taken and the average period of effectiveness is 290 hours. Calculate a 96% confidence interval for the true mean of the period of effectiveness
consider th following reaction, initially at equilibrium: N2(g) + 3H2(g) 2NH3(g) + 92 Kj J/mol would the reactants or products have the greatest amount of entropy in this rwacion
Coloring the blocks question :
Find total cost of coloring each block out of 3 colors such that cost should be minimum and not adjacent
B. There are n blocks placed in a row. Each block must be covered with one of the three colors available, but no two adjacent blocks can be the same color. The cost of coloring each block varies and is given in an array. Given the cost of using each color on each block, determine the minimum cost to color all the blocks.
C. Given colors price in rows, select a min price from the row and no two adjacent rows should have the same minimum price .
