Option 2. The equation of the parabola is given as y = one eighthx² + 5

<h3>How to read the graph</h3>

We have the coordinate plane to be passing through the graph at point C on the y axis. This is used to represent the slope.

Hence the slope is 5

The equation of the line is given as y=x²+C

Hence we can see that there is a rising slope. So the answer is Option 2.

A roulette wheel has the numbers 1 through 36, 0, and 00. A bet on four numbers pays 8 to 1 (that is, if you bet $1 and one of t

Answer:

Lose $0.05

Step-by-step explanation:

There are 38 possible spots on the roulette wheel (numbers 1 to 36, 0 and 00).

If the player can choose four numbers on single $1 bet, his chances of winning (W) and losing (L) are as follows:

$P(W) = \frac{4}{38} \\P(L) = 1-P(W) = 1-\frac{4}{38} \\P(L) = \frac{34}{38}$

The expected value of the bet is given by the probability of winning multiplied by the payout ($8), minus the probability of losing multiplied by the bet cost ($1)

$EV=\frac{4}{38}*\$8 -\frac{34}{38}*\$1\\EV= -\$0.05$

On each bet, the player is expected to lose 5 cents ($0.05).

Help am stuckkkkk please help

Otrada [13]

Step-by-step explanation:

it is a box or prism.

the volume is simply

length × width × height

in our case

8m × 6m × 5m = 240 m³

doubled dimensions means

16m × 12m × 10m = 1920 m³

the difference is

1920 - 240 = 1680 m³

we could have gotten the new volume also based on the original volume :

2×8m × 2×6m × 2×5m = 8m×6m×5m × 2×2×2 =

= the original volume (240 m³) × 8 = 1920 m³

Use graphing to find the solution of the system of equations. -x^2+y=1, -x+y=2

vladimir2022 [97]

ANSWER

$x=-0.62$ or $x=1.62$

EXPLANATION

For $-x^2+y=1$

We make y the subject to obtain,

$y=x^2+1$

We can easily graph this function, because we just have to transform the graph of $y=x^2$ by shifting the intercept up to $1$ .

As for the straight line, $-x+y=2$ ,

We find the intercepts as follows,

When $y=0,x=-2$ .

When $x=0,y=2$ .

We plot the points $(-2,0)$ and

$(0,2)$ .

We now draw the two graphs on the same graph sheet. The intersection of the two graphs gives the solution to be

$x=-0.62$ or $x=1.62$
