A set of average city temperatures in July are normally distributed
with a mean of 23.5 degrees Celsius and a standard deviation of 2 degrees
Celsius. The average temperature of the City of Van Nuys is 23 degrees
Celsius.
What percentage of average city temperatures are higher than that of the
City of Van Nuys?
a) 59.87%
b) 44.04%
C) 55.96%
d) 40.13%

a) 59.87%

Step-by-step explanation:

Given that the mean temperature (μ) = 23.5°C and the standard deviation (σ) is 2 °C.

The z score is used in statistics to measure number of standard deviation by which the raw score is above or below the mean value, It is calculated using the equation:

The average temperature of the City of Van Nuys is 23 degrees. The z score is

P(x > 23) = P(z > -0.25) = 1 - P(z < -0.25) = 1 - 0.4013 = 0.5987 = 59.87%

to find the unit price, we must figure out the cost of one item (in this case one dish towel).   to do this, we divide the total price ($7.92) by the number of items bought (for this problem it is 8, because there are eight dish towels in one pack).  

$7.92/8 = $0.99

therefore, the unit price, or the price of one dish towel, is $0.99.

hope this !

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
