Anna71 [15]

Answer:

20 miles.

Step-by-step explanation:

Let m be number of miles.

Laguana's Truck Rentals charges $20 plus $2 per mile.

Total cost of Laguana's Truck = $20+2m$ .... (1)

Salvatori's truck rentals charges $3 per mile.

Total cost of Salvatori's truck = $3m$ ... (2)

We need to find the number of hours after that the total cost for both companies will be the same.

$3m=20+2m$

$3m-2m=20$

$m=20$

Therefore, after 20 miles the total cost for both companies will be the same.

If the standard deviation is 7.3kg, what is the variance?

sasho [114]

Answer:

The variance is 53.29 kg²

Step-by-step explanation:

The standard deviation is the square root of the variance.

$S(X) = \sqrt{V(X)}$

In which problem, we have that:

$S(X) = 7.3$

$\sqrt{V(X)} = 7.3$

$\sqrt{V(X)}^{2} = (7.3)^{2}$

$V(X) = 53.29$

The variance is 53.29 kg²
