Answer:

$m=2, m=0$

-ˋˏ✄┈┈┈┈┈┈┈┈┈┈┈┈┈

$20m^2-40m=0$

<u>Use quadratic formula:-</u>

᠃ ⚘᠂ ⚘ ˚ ⚘ ᠂ ⚘ ᠃

$m_1,_2=\frac{-(-40) -+\sqrt{x} (-40)^2-4*20*0}{2*20}$

$\sqrt{(-40)^2-4*20*0}=40$

$m_1,_2=\frac{-(-40)-,+40}{2*20}$

$m_1=\frac{-(-40)+40}{2*20},m_1=\frac{-(-40)-40}{2*20}$

$m=\frac{-(-40)+40}{2*20}:2$

$m=\frac{-(-40)-40}{2*20}:0$

$m=2, m=0$

A set of city temperatures in April are normally distributed with a mean of 19.7 degrees Celsius and a standard deviation of 2 d

Sati [7]

Answer:

19.77% of average city temperatures are higher than that of Cairo

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this question, we have that:

$\mu = 19.7, \sigma = 2$
