Answer:

y=-4x-18

Step-by-step explanation:

To find the slope of the function, you need two points in order, the first point having its x and y coordinates labeled as x1 and y1, and the second point having its coordinates labeled as x2 and y2. then, use the equation for slope, which is m=(y2-y1)/(x2-x1), and plug in the numbers. You should get m=(-10+2)/(-2+4)= -8/2= -4.

Then, use the slope and a point on the graph, and plug it into point slope form, which is y-y1=m(x-x1). No matter what point you use, you should get the same thing. I used the point (-2, -4). Using this point, the steps to arrange the equation in slope intercept form is: y+2=-4(x+4)=> y+2=-4x-16 => y=-4x-18.

- 2 3/5 - 1 2/3

= -2 9/15 - 1 10/15

= (-2 9/15) + (- 1 10/15)

= -3 19/15

= -4 4/15

Answer is B

Answer:

E(Y) = $0.5

Var(Y) = 14.25

you should pay the same amount $0.5

Step-by-step explanation:

E(Y) = = Σ(YP)

P = probability of each outcomes.

Var(Y) = Σ $Y^{2}$ p − (μ x μ)

E(Y) = (2 x 0.25) +(6 x 0.25) + (0.5 x (-3)) = $0.5

Var(Y) = ( $2^{2}\\$ x 0.25) + ( $6^{2}$ x 0.25) +( $-3^{2}$ x 0.5) - ( $0.5^{2}$ )

= 14.5 - 0.25

Var(Y) = 14.25

for the difference between the payoff and cost of playing to have mean 0, you should pay the same amount $0.5

What to the tenth power can get you 300

OLEGan [10]

Answer:

1.7689 (rounded to 4 decimal places)

Step-by-step explanation:

Let the number we are seeking be "x", thus we can write the equation as:

$x^{10}=300$

Since we have raised "x" to the "10th power", to get "x" back again, we need to take 10th root. Same goes for right side, we take 10th root of 300. We will get our answer. The process shown below:

$x^{10}=300\\\sqrt[10]{x^{10}} =\sqrt[10]{300} \\x=\sqrt[10]{300} \\x=1.7689$
