Step-by-step explanation:
First find least common multiple which is 12.
A: 300 * 3= 900
B: 240* 4 = 960
Answer:
0.1069 = 10.69%
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 question:
Between 57 and 69
This is the pvalue of Z when X = 69 subtracted by the pvalue of Z when X = 57. So
X = 69
has a pvalue of 0.9918
X = 57
has a pvalue of 0.8849
0.9918 - 0.8849 = 0.1069 = 10.69%
Answer:
i.e. 393650 kg.
Step-by-step explanation:
Given that Radium-226 is a radioactive substance with an annual decay rate of 0.04 %
Let the year 1937 be 0 year
Initially population was = 400,000 kg
Since decay rate is 0.04% per year after t years population would be
=
In 2017, t = 40 years (i.e. years lapsed form 1937)
Hence population
=
i.e. 393650 kg.
Answer:
i believe its 6 units hope its right
Step-by-step explanation:
i got 6 because when you look at the top it has a 12 between it to divide that by 2 and there but v-s is just half of twelve
Wait what?- I’m confused was there supposed to be more?...
