Write a multiplication equation and a division equation that this diagram could represent.
vivado [14]

Answer:

3 * 18= 54 and 54/18 = 3

Step-by-step explanation:

Given

Sections = 3

Measurement=18 per section

Total\ Measurement=54

Required

Model the scenario

The model of this scenario is:

Sections * Measurement = Total\ Measurements

This gives:

<em />3 * 18 = 54<em> -- This represents the multiplication model</em>

Divide both sides by 18

3 * 18/18 = 54/18

3 * 1 = 54/18

3 = 54/18

Reorder

<em />54/18 = 3<em> -- This represents the division model</em>

A set of piano prices distributed at a mean of 3000 and a standard deviation of 200 dollars. An electric piano has a price of 25
lana [24]

Answer:

The proportion of piano prices higher than the electric piano is 98.3%

Step-by-step explanation:

The first thing to do here is to calculate the standard score of the price of the electric piano given.

Mathematically, this is

z-score = (x-mean)/SD

where mean is 3000 and SD is 200, x is 2576

z-score = (2576-3000)/200 = -2.12

Now we proceed to calculate the probability of this z-score

The probability we are trying to calculate is

P( x > $2576) or simply P ( z > -2.12)

Using standard score probability calculator or table, we have

P(x>2576) = 1 - P(x<2576)

But, P(x<2576) = 0.017003

P(x>2576) = 1 - P(x<2576) = 0.983

This is same as 98.3%
