In a petri dish, a certain type of bacterium doubles in number every 20 minutes
There were originally 8, or 2 bacteria in the dish. After 140 minutes, the
number of bacteria has doubled 7 times, multiplying by 2
Now the population of bacteria is 23.27 Expressed as a power, how many
bacteria are in the petri dish after 140 minutes?
A. 210
ОО
OB. 410
O C. 221
OD. 27

2x minus y equals 6, x plus y equals negative 3

Match each whole number with a rational, exponential expression 3 square root 27^2find the domain and range of the exponential function h(x)=125^x. explain your findings. as x decreases does h increase or decrease? explain. as x increases does h increase or decrease? explain.

For a science project, a high school research team conducted a survey of local air temperatures. based on the results of the survey, the found that the average temperatures were around 10 degrees higher than expected. this result was wrong. the trouble with the survey was that most of the locations were exposed to direct sunlight and located over asphalt or sand, which resulted in higher temperatures than normal. this is a classic example of an error in which phase of inferential statistics?
