<h3><u>Answer:</u></h3>

Hence, the graph that do not represent the numerical set of data is:

Circle graph.

<h3><u>Step-by-step explanation:</u></h3>

We know that a box-an-whisker plot , histogram and line graph are all used to represent the numerical set of data.

A box-and -whisker plot helps us to find the mean, median and mode and also divide the set into quartiles.

Also the histogram is formed by the set of values given and is a graph formed by the frequency of the data.

Hence, the graph that do not represent the numerical set of data is:

Circle graph.

( Since circle graph represent the percent of a data with respect to the total data)

Follow the process of completing the square to solve 2x2 + 8x - 12 = 0. After adding B2 to both sides of the equation in step 4,

valentina_108 [34]

2x2 + 8x - 12 = 0
4 + 8x - 12 = 0
8x = 12 - 4
8x = 8
x = 1

Please help logarithms!

Given:

$\log_34\approx 1.262$

$\log_37\approx 1.771$

To find:

The value of $\log_3\left(\dfrac{4}{49}\right)$ .

Solution:

We have,

$\log_34\approx 1.262$

$\log_37\approx 1.771$

Using properties of log, we get

$\log_3\left(\dfrac{4}{49}\right)=\log_34-\log_349$ $\left[\because \log_a\dfrac{m}{n}=\log_am-\log_an\right]$

$\log_3\left(\dfrac{4}{49}\right)=\log_34-\log_37^2$

$\log_3\left(\dfrac{4}{49}\right)=\log_34-2\log_37$ $[\log x^n=n\log x]$

Substitute $\log_34\approx 1.262$ and $\log_37\approx 1.771$ .

$\log_3\left(\dfrac{4}{49}\right)=1.262-2(1.771)$

$\log_3\left(\dfrac{4}{49}\right)=1.262-3.542$

$\log_3\left(\dfrac{4}{49}\right)=-2.28$

Therefore, the value of $\log_3\left(\dfrac{4}{49}\right)$ is $-2.28$ .
