Given that f(x)= x^2-3/2 find f^-1(x)
Scilla [17]

Answer:

\bold{f(x)=-\frac{1}{2}}

f(x)= x^2-\frac{3}{2}              replace x with -1

f(x)= -1^2-\frac{3}{2}           solve exponents

A bag contains 3 red marbles, 5 blue marbles and 6 green marbles. If three marbles are drawn out of the bag, what is the probabi
Romashka [77]

Answer:

0.027 to the nearest thousandth.

Step-by-step explanation:

There are 14 marbles in the bag, so:

Prob( a blue on the first draw) = 5/14.

Prob( a blue on the 2nd draw) = 4/13.

Prob( a blue on the 3rd draw) = 3/12 = 1/4.

So the required probability is 5/14 * 4/13 * 1/4

= 20/ 728

= 0.02747.

Solve for z: -0.3z=-17.4-2.3z
OleMash [197]

Answer:

z=-8.7

Step-by-step explanation:

-0.3z=-17.4-2.3z

10(-0.3z)=10(-17.4-2.3z)

-3z=-174-23z

20z=-174

z=-8.7

Check:

-0.3z=-17.4-2.3z

-0.3(-8.7)=-17.4-2.3(-8.7)

2.61=-17.4+20.01

2.61=2.61
