Answer:

The square root of 36/16

Step-by-step explanation:

When you simplify all of them like the square root of 36/6 it would 2.4494897.... which is a non termination decimal (so this is IRRATIONAL)

The square root of 6 is not a rational number because its a non termination decimal ----> 2.4494897.... (or you can say its like the same thing as the first one just you simplified so its IRRATIONAL)

The square root of 36/16 is RATIONAL because when you simplify you get 1.5 and you can turn that into a fraction

And finally the last one the square root of 16/6 is not a rational number because you get 1.632993...... as an answer which is IRRATIONAL

Hope this helps!!!!

So, for this, "x" can equal 5/2 which is fraction form, OR it can be decimal form, which would be 2.5

The scale factor that was used to create triangle J’K’L’ is 1/3

<h3>How to determine the scale factor?</h3>

From the graph, we have the following highlights:

KL = 3

K'L' = 1

The scale factor (k) from JKL to J'K'L is calculated as:

Scale factor = K'L'/KL

This gives

k = 1/3

Hence, the scale factor that was used to create triangle J’K’L’ is 1/3

Refer to the various selling prices of various homes in a community that follow the normal distribution with mu (population mean

blsea [12.9K]

Answer:

0.43715

Step-by-step explanation:

We solve using z score calculator

z = (x-μ)/σ, where

x is the raw score

μ is the population mean = $276,000

σ is the population standard deviation = 32,000

For x = $276,000

z = 276,000 - 276,000/32000

z = 0

Probability value from Z-Table:

P(x = 276000) = 0.5

For x = $325,000

z = 325,000 - 276,000/32000

z = 1.53125

Probability value from Z-Table:

P(x = 325000) = 0.93715

The probability that the next house in the community will sell for between $276,000 and $325,000 is

P(x = 325000) - P(x = 276000)

= 0.93715 - 0.5

= 0.43715
