Answer:

(b) $P(\textrm{Event of getting a 3 in the spinner)} = \frac{11}{61}$

Step-by-step explanation:

Let E: Event of getting a 3 in the spinner.

So, the number of favorable outcomes = 11

Total number of outcomes = Number of times the outcomes is {1,2,3,4,5,6}

= {13 +10 +11+16+11} = { 61}

So, the total number of outcomes = 61

$\textrm{Probability of Event E} = \frac{\textrm{Number of favorable events}}{\textrm{Total number of outcomes}}$

So, here $P(\textrm{Event of getting a 3 in the spinner)} = \frac{11}{61}$

If f(x) = x^2 - 3x + 1 over 2, determine f ( 4 ) .

svet-max [94.6K]

F(x)=x^2-3x+1/2, if f(4)
Substitute x with 4, to get
f(x)=x^2-3x+1/2
f(4)=4^2-3(4)+1/2
f(4)=16-12+1/2
f(4)=4+1/2
f(4)=4 1/2 or 4.5. Hope it help!
