Answer:

±sqrt(T*L/m)=v

Step-by-step explanation:

T=mv^2/L

We want to solve the equation for v

Multiply each side by L

T*L=mv^2/L *L

T*L=mv^2

Divide each side by m

TL/m=mv^2/m

T*L/m=v^2

Take the square root of each side

±sqrt(T*L/m)=sqrt(v^2)

±sqrt(T*L/m)=v

Answer:

\large\boxed{v=\pm\sqrt{\dfrac{LT}{m}}}

Step-by-step explanation:

\dfrac{mv^2}{L}=T\qquad\text{multiply both sides by}\ L\\\\L\!\!\!\!\diagup^1\cdot\dfrac{mv^2}{L\!\!\!\!\diagup_1}=LT\\\\mv^2=LT\qquad\text{divide both sides by}\ m\\\\\dfrac{m\!\!\!\!\diagup^1v^2}{m\!\!\!\!\diagup_1}=\dfrac{LT}{m}\\\\v^2=\dfrac{LT}{m}\qquad\text{square root of both sides}\\\\\sqrt{v^2}=\sqrt{\dfrac{LT}{m}}\qquad\text{use}\ \sqrt{a^2}=|a|\\\\|v|=\sqrt{\dfrac{LT}{m}}\Rightarrow v=\pm\sqrt{\dfrac{LT}{m}}

Based on the information given, it should be noted that the mean and standard deviation of Y will be 0.4899 and 0.699 respectively.

<h3>Calculating the mean.</h3>

Based on the information given, it should be noted that the probability distribution for y will be:

Y                   0        1.         2

Probability 0.63.   0.25.   0.12

The mean of Y will be:

= (0 × 0.63) + (1 × 0.25) + (2 × 0.12)

= 0 + 0.25 + 0.25

= 0.49

The variance will be 0.4899. Therefore, the standard deviation will be:

= ✓0.4899

= 0.699

HELP, I’M STUCK !
vaieri [72.5K]

Since P(<em>X</em> = <em>x</em>) = 0.3 for all 0 ≤ <em>x</em> ≤ <em>α</em>, we have

\displaystyle\int_{-\infty}^\infty P(X=x)\,\mathrm dx=1\implies0.3\int_0^\alpha\mathrm dx=0.3\alpha=1\implies\alpha=\dfrac{10}3

So,

P(X>2) = \displaystyle\int_2^\infty P(X=x)\,\mathrm dx=0.3\int_2^{\frac{10}3}\mathrm dx

P(X>2)=0.3\left(\dfrac{10}3-2\right)=\boxed{\dfrac25}
