The x would be 4 because it was only used once. Same for the y.

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

6 times 7 to the second power

Travka [436]

Hello!

To solve this question, we must first add the exponent into the number 7 before multiplying it by the number 6.

7 to the second power simply means 7x7.

7x7= 49

Now that the exponent is in the equation, we can multiply 49 by 6 to find your final answer.

6 x 49 = 294

I hope this helps answer your question! Have a great day!
