The Museum of Science in Boston has an exhibit in which metal balls drop down a chute, bounce around, and wind up in one of 21 bins. After 1000 balls have dropped, the heights within the bins clearly follow a bell-shaped curve. If the standard deviation is 3 bins, approximately how many balls are in bins 1 through 7?A) 100
B) 160
C) 50
C) 330

Answers

if you have 21 bins then the 'middle bin' is bin 11 (starting at 1)So the 'mean' of this distribution is 11.The SD is 3so using the above calculator (or your own tables ) you get that the probability of a ball being in bin 7 or less is .091

Biologists are treating a lake contaminated with bacteria. The level of contamination is changing at a rate of dN/dt=-1110/t² -230 bacteria percubic centimeter per day, where is the number of days since treatment began. Find a function N(t) to estimate the level of contamination if the
level after I day was 5380 bacteria per cubic centimeter.

Answers

Answer: the function N(t) to estimate the level of contamination in the lake is:

N(t) = -1110 ln(t) - 230t + 1110 ln(I) + 230I + 5380

Step-by-step explanation: ∫ dN/dt dt = ∫ (-1110/t² -230) dt

N(t) = -1110 ln(t) - 230t + C  

N(I) = -1110 ln(I) - 230I + C = 5380

C = 1110 ln(I) + 230I + 5380

1. How many centimeters are there in meter? a. 1
b. 10 c. 100
d. 1000 e. 10000

Answers

There are 100 centimeters in one meter, the correct option is (C) 100

A meter is a unit of length in the International System of Units (SI) that is used to measure distance or length. One meter is defined as the distance traveled by light in a vacuum during a time interval of 1/299,792,458 of a second.

A centimeter, on the other hand, is a smaller unit of length in the SI system.

1 centimeter = 1 / 100 meter

One centimeter is equal to one-hundredth of a meter,

Therefore, the conversion factor = 100

Which means that there are 100 centimeters in one meter.

Therefore, the correct option is (C) 100
