a train travels 288km at a uniform speed.if the speed has been 4km per hour more it would have taken one hour less for the same

Lostsunrise [7]

Given:

A train travels 288 km at a uniform speed.

If the speed has been 4 km per hour more it would have taken one hour less for the same journey.

To find:

The initial speed of the train.

Solution:

Let x km/h be the initial speed on the train.

New speed of train = (x+4) km/h

We know that,

$Time=\dfrac{Distance}{Speed}$

Time taken by the train initially to cover 288 km is $\dfrac{288}{x}$ hours.

New time taken by the train to cover 288 km is $\dfrac{288}{x+4}$ hours.

It is given that If the speed has been 4 km per hour more it would have taken one hour less for the same journey.

$\dfrac{288}{x}-\dfrac{288}{x+4}=1$

$\dfrac{288(x+4)-288x}{x(x+4)}=1$

$288x+1152-288x=x^2+4x$

$1152=x^2+4x$

$0=x^2+4x-1152$

Splitting the middle term, we get

$x^2+36x-32x-1152=0$

$x(x+36)-32(x+36)=0$

$(x+36)(x-32)=0$

$x=-36,32$

We know that the speed cannot be negative. So, the only possible value of x is 32.

Therefore, the speed of the train is 32 km/h.

If the logarithm of 5832 is 6, what is the base? <img src="https://tex.z-dn.net/?f=%20logx%285832%29%20%20%3D%206" id="TexFor

goblinko [34]

Answer:

The base is 4.2426.

Step-by-step explanation:

Logarithm definition:

Suppose we have that:

$\log_{a}{b} = c$

It means that;

$b = a^c$

In this question:

$\log_{x}{(5832)} = 6$

It means that:

$x^6 = 5832$

$x = \sqrt[6]{5832}$

$x = (5832)^{\frac{1}{6}}$

$x = 4.2626$

The base is 4.2426.

Answer:

-$0.16

Step-by-step explanation:

The expected value is the sum of the outcomes multiplied by their probabilities.

E(X) = 1/38 (+68) + 37/38 (-2)

E(X) = -0.16
