Answer:
The probability is 0.136125
Step-by-step explanation:
45% are in favor of the project, the probability of selecting someone in favor of the project will be 45/100 = 0.45
The probability of selecting someone not in favor of the project = 1 - probability of selecting someone in favor of project = 1-0.45 = 0.55
Now we have 3 people to be chosen at random with exactly one of them favoring the new building project. This means two of them will not favor the building project
Thus the probability here is = the probability of favoring * the probability of not favoring * the probability of not favoring
= 0.45 * 0.55 * 0.55 = 0.136125
A conditional statement is always true backwards and forwards
Kelvin has 14 more foreign stamps than local stamp.
Step-by-step explanation:
Given,
Total number of stamps = 112
Ratio of local stamps to foreign stamps = 7:9
Let,
The number of local stamps = 7x
The number of foreign stamps = 9x
Therefore,
Number of local stamps = 7x = 7(7) = 49
Number of foreign stamps = 9x = 9(7) = 63
Difference = 63 - 49 = 14
Kelvin has 14 more foreign stamps than local stamp.

<span>f(x) = –5x + 4
Putting x=2
</span><span>f(x) = –5(2) + 4
</span><span>f(x) = -10+4
</span>= -6
So,
x=2 , y=-6
According to above explanation,
<span>C. (2, –6) , is the correct answer.</span>
