Answer:

ra1l [238]

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.

Gaira was asked to evaluate the algebraicexpression –3.8x + 6 when x = –7.5.
icang [17]

gaira ALSO multiplied 6 by x, when 6 doesnt have 6x.

so the correct answer would be only -3.8(-7.5) + 6 which is 34.5.
