How can we interpret standard deviation using the Empirical Rule?

1 answer:

3 0

Answer:The empirical rule notes that almost all of the data would fall within three standard deviations of the mean for a normal distribution. The empirical rule can be broken down into three parts: within the first standard deviation from the mean, 68 percent of data drop. Two standard deviations account for 95 percent.

The measure of RST can be represented by the expression (6x + 12)°.

Valentin [98]

Answer:

The measure of angle RST is $120\°$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

$m$ -----> equation A

$m$ -----> equation B

equate equation A and equation B

$(6x+12)\°=78\°+(3x-12)\°$

$6x-3x=78\°-24\°$

$3x=54\°$

$x=18\°$

The measure of angle RST is equal to

$m$
