Answer: 95% of all people work between 7 hours and 9 hours per day and It is true.
Step-by-step explanation:
Since we have given that
Mean = 8 hours
Standard deviation = 0.5 hours
According to Empirical Rule,
at 95% confidence, it lies within 2 standard deviations from the mean
so, lower value is given by
upper value is given by
Hence, 95% of all people work between 7 hours and 9 hours per day.
Therefore , it is true.
There are 12 white ribbons, 15 red ribbons, and 11 blue ribbons.
38=(w-1)+(w+3)+w
combine like terms
38=2+3w
subtract 2 from both sides
36=3w
divide 3 on both sides
12=w
w-1=b
12-1=b
11=b
w+3=r
12+3=r
15=r
Check Your Work
w+r+b=38
15+11+12=38
38=38
The dot means to multiply
so 43 x 10025 -50
since BEDMAS is applied,
we would do the multiplication first
43 x 10025 = 431075
and <span>431075 - 50 is 431025
FINAL ANSWER: 431025</span>
60 is 83% of 72.
60 divided by 12 is 5, and 72 divided by 12 is six.
5/6 equals 0.83
0.83 x 100 is 83, or 83%.
<span>Brainiest would be nice.</span>
