Answer:

Step-by-step explanation:

Depending on whether or not the g(x) is x^2 or 2x, I have both ways.

If g(x) is x^2 - 9...

--> (3x^2 + 2) - (x^2 - 9) = 2x^2 + 11

If g(x) is 2x...

--> (3x^2 + 2) - (2x - 9) = 3x^2 - 2x + 11

Hope this helps!

A dartboard has 20 equally divided wedges and you are awarded the number of points in the section of your dark lands in if you a

Leto [7]

Answer:

$Pr =0.75$

Step-by-step explanation:

Given

See attachment for wedge

Required

$P(x > 5)$

The sample space of the wedge is:

$S = \{1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}$

$n(S) = 20$

The outcomes greater than 5 are:

$x > 5 = \{6,7,8,9,10,11,12,13,14,15,16,17,18,19,20\}$

$n(x>5) =15$

So, the probability is:

$Pr =\frac{(n(x>5)}{n(S)}$

This gives:

$Pr =\frac{15}{20}$

$Pr =0.75$
