What is a independent event

1 answer:

4 0

Step-by-step explanation: If two events are independent events, then the outcome of one event will not affect the outcome of the other event. I'll show an example.

Two coins are tossed. Find the probability of the following event.

P (heads and heads)

This problem would be dealing with independent events because the outcome of tossing 1 coin does not affect the outcome of tossing the second coin.

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 ,

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

If the function rule is to divide by 10, and there is an output value is 7.2, what is the input value?

Sergeeva-Olga [200]

The answer is: "72" .
______________________________________________
(input value, or "x") / 10 = y = f(x);

When y = 7.2, what is the value of "x" ?

x / 10 = 7.2 ;

x = (7.2) * 10 = 72 .

NEED HELP ASAP Find the value of x. Round to the nearest tenths place.

Oliga [24]

Answer:

x = 77.8 ft

General Formulas and Concepts:

sin∅ = opposite over hypotenuse

Step-by-step explanation:

<u>Step 1: Define</u>

∅ = 40°

opposite leg of angle = 50 ft

hypotenuse = x ft

<u>Step 2: Solve for </u><em><u>x</u></em>

Substitute: sin40° = 50/x
Multiply <em>x </em>on both sides: xsin40° = 50
Divide sin40° on both sides: x = 50/sin40°
Evaluate: x = 77.7862
Round: x = 77.8 ft
