A set of data with a mean of 53, and a standard deviation of 6.2 is normally distributed. Find the value of a data point that is
Evgesh-ka [11]

The value of a data point that is -2 standard deviations from the mean

so, 40.6 to 65.4.

<h3>What is the empirical rule?</h3>

According to the empirical rule, also known as the 68-95-99.7 rule, the percentage of values that lie within an interval with 68%, 95%, and 99.7% of the values lies within one, two, or three standard deviations of the mean of the distribution.

P(\mu - \sigma < X < \mu + \sigma)  \approx 68\%\\P(\mu - 2\sigma < X < \mu + 2\sigma)  \approx 95\%\\P(\mu - 3\sigma < X < \mu + 3\sigma)  \approx 99.7\%

From the empirical rule, we know that for 95% we are in 2 standard deviations of the mean. so:

= 53- 6.2- 6.2

= 40.6

The value of a data point that is -2 standard deviations from the mean

53 + 6.2 + 6.2

= 65.4

Pls help me with 13 you will get Brainly the instructions are to evaluate the following a=6, b=3,c=2 please answer this question
scoundrel [369]

You have to plug in the values into the equation.

Since a=6, all the a's in the equation would be replaced by 6 and same goes for the b.

^ means exponent btw

= -[2(6)^2 -6- (5(6)^2-3(3)) -4(6)^2 +2(3)]

Calculate/ simplify

= -[2(36)-6 - (5(36) -9)-4(36)+6]

Multiply all the things in parenthesis

= -[72-6-(171)-144+6]

Add/subtract

= -[-243]

Negative times negative becomes positive therefore, the answer becomes 243

May I get some help please
Vera_Pavlovna [14]
The correct answer is the one on the left bottom. No matter what, if you subtract a value less than the amount ABOVE 1 in this situation, then you will always end up with more than 1.

Describe the difference between collinear points and coplanar lines..
Tema [17]
Notice the word LINE in COLLINEAR. <span>Collinear points are points that lie ON A LINE. Any two points are always collinear because you can always connect them with a straight line.
Notice the word PLANE in COPLANAR. </span> <span>A group of points that lie IN THE SAME PLANE are coplanar. Any two or three points are always coplanar. 
I hope you get the answer you needed.
