Answer:
P(x) = 45/100 = 0.45
Mean sample distribution = probability x number sampled by the survey.
Mean sample distribution = 0.45 x 800 = 360.00 to two decimal places.
Step-by-step explanation:
 Convert the percentage to decimal probability. 
45%. P(x) = 45/100 = 0.45
 If there are ranges of probability values, we construct a probability distribution table. This is not necessary in the case of one probability value(45%)
Multiply the probability by the number adults to be surveyed on whether they have received phishing emails.
0.45 x 800 = 360.
Here, we assume that the 45% recorded by 2005 data, is still valid for the recent trends.

but this would have to be simplified also

Answer:
C) The resulting figure will be congruent to the original rectangle, because dilations with a scale factor of 1 have the same coordinates. 
Step-by-step explanation: Multiplying any number by 1 will result in the same number, this applies to coordinates as well.  
 
        
             
        
        
        
Answer:
running 1.5 hours
Walking 4.5 hours
Step-by-step explanation:
Let the amount of time she spends on walking be x
d/3 + d/9 = 6            Multiply by 9
3d + d = 6*9
4d = 54                     Divide by 4
4d/4 = 54/4             
d = 13 2/4 = 13 1/2 = 13.5 miles
d/3 = 13.5/3 = 4.5 hours
d/9 = 13.5/<u>9 = 1.5 hours</u>
Total                6 hours
I hope this is the right interpretation.
