A population of bacteria is treated with an antibiotic. It is estimated that 5,000 live bacteria existed in the sample before tr
1 answer:
Answer:
Step-by-step explanation:
The function is modeled after
where a is the initial amount and b is the growth/decay factor. If we start with 5000 bacteria, then a = 5000. The decay factor is determined by the rate at which the bacteria decrease. We know that rate at which the bacteria decrease is 60% because 40% are left alive; therefore, b = .4:
with a horizontal asymptote of y = 0, the first choice.

We get
Thus is eliminated.
So, the expression used to eliminate is:
Answer:

b)
c) Kyle's systolic blood pressure is 1.75 standard deviations above the average systolic blood pressure for men.
d)
Step-by-step explanation:
Problems of normally distributed samples are solved using the z-score formula.
In a set with mean and standard deviation
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
(a) 100 millimeters z-score =
(b) 150 millimeters z-score =
(c) Kyle's doctor told him that the z-score for his systolic blood pressure is 1.75. Which of the following is the best interpretation of his score?
1.75 standard deviations above the mean systolic blood pressure of males.
The problem does not talk about age.
So the answer is:
Kyle's systolic blood pressure is 1.75 standard deviations above the average systolic blood pressure for men.
d) Calculate Kyle's blood pressure
This is X when Z = 1.75. So
