Answer:
27,000
Step-by-step explanation:
We have been given that after a dose of an antibiotic, the number of bacteria decreases. The equation is
models this "decay" situation. We are asked to find the original number of bacteria.
We know that an exponential decay function is in form
, where,
y = Final value,
a = Initial value,
b = Decay factor,
x = Time.
Upon looking at our given equation, we can see that initial value is 27,000, therefore, 27,000 represents the original number of bacteria.
Northerly 835cos41.5=625.4km/h
westerly 835sin41.5=553.3km/h
Answer:
10
Step-by-step explanation:
As it could be inferred from the name, repeated measure design may be explained as experimental measures involving multiple (more than one) measures of a variable on the same observation, subject or participants which are taken at either various times or periodic intervals, different levels, different conditions. Hence, a repeated measurement taken with the same sample but under different treatment conditions. Therefore, since the measurement will be performed on a the same subjects(paired) , then the number of subjects needed will be 10. As it is this same samples that will be used for the other levels or conditions.
