Answer:

Independent events

Step-by-step explanation:

Given that:

Ramiro draws a marble from a jar without replacement and then flips a coin

Let E_1 be the event that Ramiro draws a marble without replacement and;

Let E_2 be the event of flipping a coin.

Let's have an analogy so that we can better understand the concept of independent and dependent events.

Consider a random experiment in which a marble is drawn from a jar without replacement and a fair coin is flipped together.

The event E_1  does not in any way affect the event E_2  of a head or a tail showing up in  a flip of a coin.

Therefore, we say that E_1  and E_2   are independent events.

Suppose the event  E_1  affects or influence the event E_2  , then we can say they are dependent events.

I need help To find gradient and y-intercept...
suter [353]

Answer:

a) the gradient of the linear graph is: \mathbf{\frac{-1}{3} }

b) the y-intercept of linear graph is -1

Step-by-step explanation:

a) Find the gradient of the linear graph.

The formula used to find gradient is same as slope

Gradient=\frac{Change \ in \ y \ coordinate}{Change \ in \ x \ coordinate}\\or\\Gradient=\frac{y_2-y_1}{x_2-x_1}

Take any 2 points from the graph.

I will take: (-3,0) and (0,-1)

Putting values in formula and finding gradient

Gradient=\frac{y_2-y_1}{x_2-x_1}  \\Gradient=\frac{-1-0}{0-(-3)} \\Gradient=\frac{-1}{3}

So, the gradient of the linear graph is: \mathbf{\frac{-1}{3} }

b) Find the y-intercept of linear graph

The y-intercept of linear graph is the value of y at the point where the line crosses the y axis.

So, in the given graph, that point is -1

So, the y-intercept of linear graph is -1

The linear combination method is applied to a system of equations as shown.
tensa zangetsu [6.8K]

Answer:

(9,3)

Step-by-step explanation:

4(.25x + .5y = 3.75) → x + 2y = 15

(4x – 8y = 12) → x – 2y = 3

2x = 18

Divide both sides by 2

x = 9

Substitute x = 9 into  x + 2y = 15

9 + 2y = 15

Subtract 9 from both sides

2y = 6

Divide both sides by 2

y = 3

Solution

(9, 3)

To decrease an amount by 19% multiply by
yawa3891 [41]
Think of the original amount as 100%
If we want 100% of something we multiply by 1
To get from 100% to 1, we divide the percentage by 100
Decrease 100% by 19%
100% - 19% = 81%
Then to get the multiplier, divide by 100
81% / 100 = 0.81
To decrease by 19%, multiply by 0.81
