Answer:

B

Step-by-step explanation:

It's B

First we multiply the coefficients. 6*3= 18, so we can immediately cross out A and D. Now, c^2 * c is c^3. So, its B.

Hope this helps !!

2. If the largest bug and the smallest bug were put together end to end, how long would they be?​
mixas84 [53]

Answer:

62.4+ 0.005= 62.405

Step-by-step explanation:

A new species of stick insect in southern China has been declared the world's longest bug, state media announced on Thursday. Until now, that honor had belonged to Malaysian stick insect named Phoebaeticus chani, or Chan's megastick. At 62.4 centimeters, the newcomer extends the record by about 6 centimeters.

The smallest known adult insect is a parasitic wasp, Dicopomorpha echmepterygis. These tiny wasps are often called fairyflies. Males are wingless, blind and measure only 0.005 inches (0.127 mm) long.

Answer:

Correlation between x and y is 0.9508          

Step-by-step explanation:

We are given the following in the question:

Distance(x):   1     4       6     6       6       7

      Days(y):  2    20    29    38     44     50

We have to find the correlation between x and y.

\sum y = 183\\\sum x=30\\\bar{x} = \displaystyle\frac{\sum x}{n} = \frac{30}{6} = 5\\\\\bar{y} = \displaystyle\frac{\sum y}{n} = \frac{183}{6} = 30.5\\\\(x-\bar{x}) = -4,-1,+1,+1,+1,+2\\(y-\bar{y}) = -28.5,-10.5,-1.5,7.5,13.5,19.5\\\sum (x-\bar{x}) (y-\bar{y})  = 183\\\sum(x-\bar{x})^2 = 24\\\sum(y-\bar{y})^2= 1543.5\\

Formula:

r = \dfrac{\sum(x-\bar{x})(y - \bar{y})}{\sqrt{\sum(x-\bar{x})^2\sum(y-\bar{y})^2}}

Putting values, we get,

r = \dfrac{183}{\sqrt{24\times 1543.5}} = 0.9508

Thus, correlation between x and y is 0.9508
