Answer:

For the experimental outcomes to be closer to the predicted outcome, the number of trials should be increased.

If the number of trials is changed, the experimental probability also changes.

If the number of trials is changed, the predicted number of outcomes also changes.

If the number of trials is changed, the number of experimental outcomes also changes.

Answer:

The y-intercept is $b=0$

The y-intercept represents the initial quantity of gas in the canister which is zero.

Step-by-step explanation:

The y-intercept is where the graph of the straight line touches the y-axis.

From the graph, the y-intercept is the origin (0,0).

Recall that the slope intercept form of a straight line is $y=mx+b$ , where $b=0$ is the y-intercept in this case.

Since the graph represents the amount of gasoline in a canister after Joshua begins to fill it at the gas station pump, the y-intercept means the initial gallons of gas in the canister is zero.

the formula for the volume of a cone can be constructed using what fraction of the area of a circle formula?

ss7ja [257]

$\bf \textit{area of a circle}\\\\
A=\pi r^2\\\\
-------------------------------\\\\
\textit{volume of a cone}\\\\
V=\cfrac{\pi r^2 h}{3}\implies V=h\left( \stackrel{\textit{a third of a circle's area}}{\cfrac{\pi r^2}{3}} \right)$

Using the quadratic formula to solve 7x^2-x=7, what are the values of x?

ycow [4]

Quadratic equation is $x= \frac{-b {\pm} \sqrt{ b^{2}-4ac}}{2a}$ WHEN
$a x^{2} +bx+c=0$

So, to make this true subtract 7 from each side.

The equation is now 7 $x^{2}$ - x - 7 = 0

Values for a, b, and c: a = 7, b = -1, c = -7

Plug these variables into the quadratic equation.

$x= \frac{1 {\pm} \sqrt{ -1^{2}-4*7*-7}}{2*-7}$

Square -1 to get 1 and multiply -4 x 7 x -7 to get 196.

$x= \frac{1 {\pm} \sqrt{1+196}}{2*-7}$

Multiply 2 x -7 to get -14, the denominator, and add 1 to 196.

$x= \frac{1 {\pm} \sqrt{197}}{-14}$

Since 197 is not a square number, and I don't know if you want to leave it in radical form or not, I will just because it's easier to understand.

Hope this helps!
