babunello [35]

Solution:

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

1. For Best Actor

X_{1}= 59 years

\sigma=7.3, \mu=42.0

Z, Score for best actor named, Z_{1}

Z_{1}=\frac{59-7.3}{42}\\\\Z_{1}= \frac{51.7}{42}\\\\Z_{1}=1.23095\\\\ Z_{1}=1.24

Z-Score for best actor = 1.24

2. Z , Score for best supporting actor , called Z_{2}

X_{2}=49 years

\sigma=15, \mu=49.0

 Z_{2}=\frac{49-15}{49}\\\\Z_{2}= \frac{34}{49}\\\\Z_{2}=0.6938\\\\ Z_{2}=0.70      

Z-Score for best supporting actor = 0.70

Z-Score is usually , the number of standard deviations from the mean a point in the data set is.

3. As, Z_{1}=1.24

So, we can say that,Option (B) The Best Actor was more than 1 standard deviation above is not unusual.

4.As, Z_{2}=0.70

solniwko [45]

Answer:

Minimum temperature is 68.5 ° and maximum temperature is 76.5 °

Step-by-step explanation:

Given :

|x – 72.5| = 4.

When the Temperature of x is minimum So the Minimum temperature  is

|x - 72.5| = 4\\it\  can \ be \ written \ as \\72.5-x=4\\-x=4-72.5\\x=68.5

When the Temperature of x is maximum So the Maximum Temperature is

|x -72.5| = 4\\x-72.5=\ 4\\x=72.5+4\\x=76.5

Therefore The minimum temperature is 68.5 ° and the maximum temperature is 76.5 °
