Mathematics
1 answer:
Nataly_w [17]2 years ago
8 0

Answer:

0.5

Step-by-step explanation:

We are given that

Number of data value=2105

Sum of data values=1008.08

We have to find the average .

We know that

Average=\frac{sum\;of\;data}{total\;number\;of\;data\;values}

Using the formula

Average=\frac{1008.08}{2105}

Average=0.47\approx 0.5

Hence, the average=0.5

Solve the following equations.<br> √3 ⋅ 3^3x = 9
GREYUIT [131]

Answer:

The solution is x = 0.5

Step-by-step explanation:

We need to write everything as a power of 3.

We know that:

\sqrt{a} = a^{0.5}

So

\sqrt{3} = 3^{0.5}

And

9 = 3^{2}

This following property is also important:

\frac{a^{b}}{a^{c}} = a^{b-c}

To solve, the first step is putting everything with the variable x on one side and everything without the variable x on the other side

\sqrt{3}.3^{3x} = 9

3^{0.5}.3^{3x} = 3^{2}

3^{3x} = \frac{3^{2}}{3^{0.5}}

3^{3x} = 3^{2-0.5}

3^{3x} = 3^{1.5}

This means that:

3x = 1.5

x = \frac{1.5}{3}

x = 0.5
