Answer:
a: x − 2y = −12
Step-by-step explanation:
the standard form of a line is is usually given as Ax + By = C, so just by deduction you can tell that the correct answer is a.
If you want to do the procedure it would be:
y − 3 = 1/2 (x + 6)
y − 3 = 1/2 x + 3
y - 1/2 x = 3 + 3
y - 1/2 x = 6
(y - 1/2 x = 6) * 2 to get rid of the fraction
2y - x = 12 rearrenge the terms
x - 2y = -12
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
