Please help me with this
Gnoma [55]

Given:

The equation is:

3^x\times 9=3^{2n-1}

To find:

The value of n in terms of x.

Solution:

We have,

3^x\times 9=3^{2n-1}

It can be written as

3^x\times 3^2=3^{2n-1}

3^{x+2}=3^{2n-1}                [\because a^ma^n=a^{m+n}]

On comparing the exponents, we get

x+2=2n-1

Add 1 on both sides.

x+2+1=2n-1+1

x+3=2n

Divide both sides by 2.

\dfrac{x+3}{2}=n

Therefore, the value of n is terms of x is n=\dfrac{x+3}{2}.

The mode interval in a histogram is the interval that has the highest frequency.
raketka [301]
This is true. 

When we're talking about the mode, we're usually talking about the number which has the highest frequency in a given set of numbers. For example, out of the numbers:

1 2 3 4 5 6 5 4 5 5 5 

5 will be the mode.
