 x =(-2-√-12)/8=(-1-i√ 3 )/4= -0.2500-0.4330i

x =(-2+√-12)/8=(-1+i√ 3 )/4= -0.2500+0.4330i

x = 1/2 = 0.500

Which measure of central tendency best describes this situation: the numbers of apples in 2-lb bags?
katrin [286]

Which measure of central tendency best describes this situation:

The number of apples in 2-lb bags?

Solution: The best measure of central tendency to describe the numbers of apples in 2-lb bags is mean. Because the variable under consideration is numeric and probably we would not see outliers in 2-lb bags.

Mean is the defined as the sum of observations divided by the number of observation. The mean takes into account all the observation of the data. Mean is most preferable when the data is numeric and there are no outliers in the data.

Therefore, in the given situation, where we have number of apples in 2-lb bags, the mean will be best to use.

A student needed to prepare 500mL of 1X TAE buffer to run a QC gel. The stock solution in the lab is 5X TAE. What volumes of sto
Xelga [282]

Answer:

you need 100ml of 5X TAE and 400ml of water.

Step-by-step explanation:

You need to use a rule of three:

C_1V_1=C_2V_2

where:

\left \{ {{C_1= 5X} \atop {C_2=1X}} \right.

and

\left \{ {{V_1 = V_{TAE}} \atop {V_2=500ml}} \right.

Therefore:

V_{TAE} = \frac{V_2*C_2}{C_1}

V_{TAE} = 100ml

Then just rest the TAE volume to the final Volume and you get the amount of water that you need to reduce the concentration.
