Step-by-step explanation:
Any lines that are parallel to each other have the same slope (coefficient of x is the same)
In this case, y = 2x + c.
Since it includes the point (0, 1), the y-intercept is 1 and that is c itself.
Hence, the equation of the parallel line is y = 2x + 1.

Answer:
16% probability that a randomly chosen U.S. adult sleeps more than 8.7 hours per night
Step-by-step explanation:
The Empirical Rule(Standard Deviation) 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 deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 7.5
Standard deviation = 1.2
Using the Standard Deviation Rule, what is the probability that a randomly chosen U.S. adult sleeps more than 8.7 hours per night?
8.7 = 7.5 + 1.2
So 8.7 is one standard deviation above the mean.
By the Empirical Rule, 68% of the measures are within 1 standard deviation of the mean. The other 100-68 = 32% are more than one standard deviation from the mean. Since the normal probability distribution is symmetric, 16% are more than one standard deviation below the mean and 16% are more than one standard deviation above the mean(above 8.7 hours)
So, 16% probability that a randomly chosen U.S. adult sleeps more than 8.7 hours per night
Answer: 12.5
Step-by-step explanation:
you go on the web and google area of trapezium
They would run 6.55 miles because first you do 131 divided by 5 which equals 26.2 so then you would do 26.2 divided by 4 and that equals 6.55
