The mean of a normal probability distribution is 500 and the standard deviation is 10. about 95 percent of the observations lie
PIT_PIT [208]

Answer:

So about 95 percent of the observations lie between 480 and 520.

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:

The mean is 500 and the standard deviation is 10.

About 95 percent of the observations lie between what two values?

From the Empirical Rule, this is from 500 - 2*10 = 480 to 500 + 2*10 = 520.

So about 95 percent of the observations lie between 480 and 520.

Can someone help me find the equation for this line please
pogonyaev

Answer:

y = x + 1

Step-by-step explanation:

The line y = x  goes through the origin, and forms a perfect 45 degree angle with the x axis.

This is that same line, moved upward 1 unit, so the y value comes out 1 unit more.

Also, in y = mx + b form (slope-intercept form), we see slope m = 1 and y-intercept b = 1, so

y = 1x + 1 = x + 1

y = x + 1
