Answer:

3.37 times

Step-by-step explanation:

Probability of hitting and odd number= 3/5

Probability of hitting and odd number=2/5

Probability of hitting and odd number three times= (3/5)^3

Probability of hitting and odd number three times=(2/5)^3

Now

(3/5)^3 / (2/5)^3 = 3.37

Hence Probability of hitting an odd number three times is 3.37 times more than the probability of hitting an even number three times !

If f(x) = 7(x - 2) + 4(x + 1), what is f(2)?<br><br> A. 9 B. 10 C. 12 D. 11
KatRina [158]

Answer:

C) 12

Step-by-step explanation:

These type of questions is basically asking you to replace x with 2. f(x) is the same thing as y = but inside the f(x) is the value of x. So in this case, the numerical value of x is 2. All we need to do is replace x with it's numerical value, 2, and solve the equation.

y=7(2-2) + 4(2+1)\\y=7(0) + 4(3)\\y = 12
