Answer:
A value two standards deviation from the mean is more likely to occur than a value three standard deviations from the mean.
Step-by-step explanation:
Standard deviation is a quantitative measure of the variability of traits of the subjects in a given population. These traits can range from age, height, weight e.t.c. This deviation is brought about by extreme or abnormal conditions, which is the reason why two deviations is more likely to occur than three deviations.
Moreover, going by the provisions of the empirical rule, If data comes from a population that is approximately symmetrical;
95% of the data will fall within two standard deviations.
99.7% will fall within three standard deviations
Find the attachment below.
Nevertheless, in a symmetrical distribution most of the data values fall around the mean. Two standard deviations is closer to the mean than 3 standard deviations hence more likely to occur.
6/9 - 1/2 = 3/18 = 1/6
So, 9 and 2 is equivanlent to 19
and 6/9 x 2 = 12/18
1/2 x 9 = 9/18
so it's
12/18 - 9/18 = 3/18 = 1/6
I hope this helps
Answer:
The sum of their ages is 1 less than 3 times Rosa's age.
15 + 8 = 3(8) - 1
Step-by-step explanation:
You can use this ratio:
1hour/60minutes=0.73hours/Xminutes
and cross multiply
so x= 43.8 minutes
X=10 and X=3/4 basically it’s whatever X equals to make the inside the parentheses equal zero. So if I were to plug 10 into the first parentheses you’d have 10-10 which equals zero. Also the zero has to the the opposite sign of what’s in the parentheses. So if -10 is in the parentheses then the zero has to be the opposite so positive 10.
