Compute the mean wages and coefficients of variations for the employees working in two factories. Factories. Which factory wages are more consistent. Wages Factory A Factory B 30 - 35 12 4 35 - 40 18 10 40 - 45 29 31 45 - 50 31 67 50 - 55 16 35 55 - 60 8 15

linearly: 8560 bacteria

exponentially: approximately 75233 bacteria

step-by-step explanation:

assuming it is not exponential (we would have some really complicated logarithms), let's say it is linear. then, after 5 hours, it increased by 1200 bacteria, so every hour it increases by 240 bacteria. this means that after 19 hours, we get 19 * 240 + 4000 bacteria or 3800 + 760 + 4000 = 7800 + 760 = 8560 bacteria.

because it says round your answer, i will do this exponentially (with a calculator, of course). first, we need to find how much it multiplies by every hour, by taking the 5th root of 52/40 or 13/10. this is approximately 0.167. we still need to add 1 to this, because we are multiplying by that number, not adding that amount of the number. now, we just calculate 4000 * (1.167)^19. use a calculator to get approximately 75232.6, or 75233.

the answer will be -6x^2 +46

step-by-step explanation:

a fish tank full of water and then fish, regardless of the shape of it, has a certain volume.   volume is how much of something fills up the inside of a shape.   if the shape of the tank is a sphere, thr volume formula for a sphere is

we are given that the diameter of the sphere is 14, so that means that the radius is half of that at 7.   filling in to find the volume of the sphere:

do the math on that and you find that the volume of the tank is 1436.755

if there is to be 1 fish for every 693 cubic inches, we must divide the total volume of the tank by 693 to get the number of fish that will fit comfortably.

1436.755/693 = 2.07

since you can't have .07 of a fish, we round down to the nearest whole number to get that 2 fish will be able to swim comfortably in the tank.
