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) )
Answer:
a=8.06
A=29.74
B=60.26
Step-by-step explanation:
This is a right angled triangle and Pythagoras theorem is to be obeyed.
To get c, we follow the Pythagoras rule that says
Hyp² = Opp² + Adj²
c= Hypotenuse
c²= a² + b²
c² = 4² + 7²
c² = 65
c = √65 = 8.06
For angle A,
the opposing side to the angle = a = 4
The adjacent side to the angle = b = 7
Following trigonometry rule.
Tan A = opp/adj
Tan A = 4/7
A = Tan–¹(4/7)
A = 29.74°
For angle B,
Opposing side = 7
Adjacent side = 4
Tan B = 7/4
B = Tan-¹(7/4)
B = 60.26°
Distance between two points is
Root of X2 - X1 squared + Y2 - Y1 squared
So here X2 is 0 X1 is 0 as the origin is 0,0
Root of Y2-Y1 squared is what we are left with
Root of -2- -3 squared
Root of 1 squared
Root of 1
Which is 1
Distance is 1

Steps To Solve:
8y - 3 = бу + 17
~Subtract 8y to both sides
8y - 3 - 8y = бу + 17 - 8y
~Simplify
-3 = -2y + 17
~Subtract 17 to both sides
-3 - 17 = -2y + 17 - 17
~Simplify
-20 = -2y
~Divide -2 to both sides
-20/-2 = -2y/-2
~Simplify
10 = y

Hence, the answer is
