Answer:

-1

Step-by-step explanation:

Simply plug in (-1) to both equations and add.

Equation 1:

2(-1)^2 = 2

3(-1) = -3

2 + -3 - 1 = -2

Equation 2:

-( - 1) = 1

Add both together:

-2 + 1 = -1

Answer:

The equation is 2x² + 3x - 1 and here f(x) is -1

<u>Putting</u><u> </u><u>f</u><u>(</u><u>x</u><u>)</u><u> </u><u>=</u><u> </u><u>-</u><u>1</u>.

f(x) = 2 {( - 1)}^{2}  + 3( - 1) - 1

f(x) = 2 (1)   - 3 - 1

f(x) = 2  - 3 - 1

f(x) =  - 1 - 1

f(x) =  - 2

For g(x) put as -1

g(x) =  - ( - 1)

g(x) =   1

<u>Last</u><u> </u><u>step</u><u>,</u><u> </u>

-2 + 1 = -1

<u>So</u><u>,</u><u> </u><u>option</u><u> </u><u>(</u><u> </u><u>a</u><u>)</u><u> </u><u>is</u><u> </u><u>correct</u><u> </u>

The probability of drawing two aces from a standard deck is 0.0059. We know this probability, but we don't know if the first car
ivanzaharov [21]

Answer:

Option C is right

C. They are independent because, based on the probability, the first ace was replaced before drawing the second ace.

Step-by-step explanation:

Given that the  probability of drawing two aces from a standard deck is 0.0059

If first card is drawn and replaced then this probability would change.  By making draws with replacement we make each event independent of the other

Drawing ace in I draw has probability equal to 4/52, when we replace the I card again drawing age has probability equal to same 4/52

So if the two draws are defined as event A and event B,  the events are  independent

C. They are independent because, based on the probability, the first ace was replaced before drawing the second ace.
