Y - 3x = -8
y = 3x - 8...slope here is 3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So the slope we need is -1/3.
y = mx + b
slope(m) = -1/3
(3,2)...x = 3 and y = 2
now we sub and find b, the y int
2 = -1/3(3) + b
2 = -1 + b
2 + 1 = b
3 = b
so ur perpendicular equation is : y = -1/3x + 3
-1/2 is your answer to this question
The correct answer is 2 3/4
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.
