Is this number written in scientific notation? 33.4 × 10 − 2 Group of answer choices Yes it is in scientific notation No it is n

Rus_ich [418]

Answer:

<h3>No it is not in scientific notation</h3>

Step-by-step explanation:

The standard form of a scientific notation is expressed as:

A * 10^n where;

A is any number from between 1 and 10

Given the expression 33.4 × 10^ − 2

Comparing with the general formula, you will see that A = 33.2

Since the value of A does not fall between 1 and 10, hence the expression 33.4 × 10^-2 is not a scientific notation

Check the explanation

Step-by-step explanation:

Following table shows the calculations:

Delta, X Southwest , Y X^2 Y^2 XY

45.96 38.76 2112.3216 1502.3376 1781.4096

46.8 45.41 2190.24 2062.0681 2125.188

47.93 15.7 2297.2849 246.49 752.501

51.78 49.58 2681.1684 2458.1764 2567.2524

52.17 44.34 2721.7089 1966.0356 2313.2178

47.36 18 2242.9696 324 852.48

Total 292 211.79 14245.6934 8559.1077 10392.0488

Sample size: n =6

Now

$S_{yy}=\sum y^{2}-\frac{\left (\sum y \right )^{2}}{n}=1083.27$

$S_{xx}=\sum x^{2}-\frac{\left (\sum x \right )^{2}}{n}=35.03$

$S_{xy}=\sum xy-\frac{\left (\sum x \right )\left (\sum y \right )}{n}=84.94$

The coefficient of correlation is :

$r=\frac{S_{xy}}{\sqrt{S_{xx}S_{yy}}}=0.436$
