Answer:

x = - 1

Step-by-step explanation:

f(x) = 2x - 10 and f(x) = - 12, then equating gives

2x - 10 = - 12 ( add 10 to both sides )

2x = - 2 ( divide both sides by 2 )

x = - 1

Answer:

(a) 0.76

(b) 0.46

(c) 0.58

Step-by-step explanation:

Let's first list the probabilities of each event:

Buyers using online search engine: 0.65

Buyers skipping test drive = 0.11

Buyers that use search engines AND skip test drives = 0.65 * 0.11 = 0.07

(a) To find this probability, we simply need to add the probabilities of the above conditions that meet the criteria of the question. Since all of the above conditions meet the criteria set by the question, we have:

Probability = 0.65 + 0.11

Probability = 0.76

(b) The probability of buyers that do not use search engines = 1 - 0.65 = 0.35

Probability of buyers that do not use search engines OR do skip the test drive = 0.35 + 0.11 = 0.46

(c) Probability of buyers buyers that do not skip test drive = 1 - 0.11 = 0.89

Probability of buyers using online search engine AND not skipping the test drive = 0.65 * 0.89 = 0.58

(It must be noted that question c is phrased wrong. Since both events are independent, i.e buying a car OR skipping the test drive would mean 0.65 + 0.89 = 1.54 (not possible) )
