Answer:
41.64% probability that a butterfly will live between 12.04 and 18.38 days.
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:

Find the probability that a butterfly will live between 12.04 and 18.38 days.
This is the pvalue of Z when X = 18.38 subtracted by the pvalue of Z when X = 12.04. So
X = 18.38



has a pvalue of 0.4168
X = 12.04



has a pvalue of 0.0004
0.4168 - 0.0004 = 0.4164
41.64% probability that a butterfly will live between 12.04 and 18.38 days.
Answer:
-90000
Step-by-step explanation:
30^3=30*30*30=27000
20^3=20*20*20=8000
50^3=50*50*50=125000
------------------------
27000+8000-125000
35000-125000
-90000
If x is the number of cans, 870-x is the number of bottles
The weight of 1 can is 14oz, the weight of x cans is 14x
The weight of 1 bottle is 70oz, the weight of 870-x bottles is 70(870-x)
The weight in total is 14x+70(870-x)
Answer:
y=-f(x)-3
Step-by-step explanation:
when f is negative it is reflected over the x-axis and -3 means to translate 3 units down
