(7,9) has a slope of 1. Write equation in slope intercept form

Nadya [2.5K]

Step-by-step explanation:

Here, slope of the line (m) = 1

Here, slope of the line (m) = 1And, the line passes through the point (7,9)

Equation of the line is given by 

y - y1 = m ( x - x1 )

y - 9 = 1( x - 7)

y - 9 = x -7

x -7+9-y = 0

x - y + 2 = 0 

 is the required equation of the line.

ELEN [110]

Using the Empirical Rule and the Central Limit Theorem, we have that:

About 68% of the sample mean fall with in the intervals $1.64 and $1.82.

About 99.7% of the sample mean fall with in the intervals $1.46 and $2.

<h3>What does the Empirical Rule state?</h3>

It states that, for a normally distributed random variable:

Approximately 68% of the measures are within 1 standard deviation of the mean.

Approximately 95% of the measures are within 2 standard deviations of the mean.

Approximately 99.7% of the measures are within 3 standard deviations of the mean.

<h3>What does the Central Limit Theorem state?</h3>

By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation $s = \frac{\sigma}{\sqrt{n}}$ .

In this problem, the standard deviation of the distribution of sample means is:

$s = \frac{0.657}{\sqrt{50}} = 0.09$

68% of the means are within 1 standard deviation of the mean, hence the bounds are:

1.73 - 0.09 = $1.64.

1.73 + 0.09 = $1.82.

99.7% of the means are within 3 standard deviations of the mean, hence the bounds are:

1.73 - 3 x 0.09 = $1.46.

1.73 + 3 x 0.09 = $2.
