Use the following table to determine P(X>4).

STatiana [176]

Answer:

0.11

Step-by-step explanation:

To get the probability above, we simply look for the events greater than 4, then add their probabilities

That is;

P(5) + P(6) + P(7)

So the probability in this case will be;

0.07 + 0.03 + 0.01 = 0.11

Which ordered pair is a solution to the system of linear equation? 2x+ 3y=6 <br> -3x+5y=10

allochka39001 [22]

Answer:

Step-by-step explanation:

2x + 3y = 6________( 1 )

-3x + 5y = 10_______( 2 )

( 1 ) × 3 ---- 6x + 9y = 18_____( 3 )

( 2 ) × 2 ---- -6x + 10y = 20_____( 4 )

$(4) + (3) \\ 6x + 9y + ( - 6x + 10y) = 20 - 18 \\ 6x + 9y - 6x - 10y = 2 \\ y = 2$

y = 2 ,

$2x + 3y = 6 \\ 2x + 3(2) = 2 \\ 2x + 6 = 2 \\ 2x = 2 - 6 \\ 2x = - 4 \\x = \frac{ - 4}{2} \\ x = ( - 2) \\$
