The arrangement in order would be 22.5, 31, 41.5, 49.85, 52.9, 56.05
the mean would be $42.30 (Added all and divided by 6)
the median would be $45.68 (41.5+49.85=91.35/2= 45.675)
there would be no mode.
The third angle is 60 degrees. A triangle has 180 degrees so 180-30-90=60
2 6/8 + 1 4/8 + 3 3/8
2 + 1 + 3 = 6
6/8 + 4/8 + 3/8 = 13/8
So 6 13/8 or 7 5/8
Answer:
c. 3.6 and 10.4 hrs
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviations of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean 7, standard deviation 1.7.
For about 95% of students, nightly amount of sleep is between
7 - 2*1.7 = 7 - 3.4 = 3.6 hours
7 + 2*1.7 = 7 + 3.4 = 10.4 hours
So the correct answer is:
c. 3.6 and 10.4 hrs
Answer:
C.
Step-by-step explanation:
Let , and . From statement we know that , which is equivalent to the following linear algebraic formula:
(1)
(2)
Then, the coordinates of point B on AC are:
Which means that correct answer is C.
