In Swaziland, a baboon's fibula was notched, indicating counting, dated back to about 35000 BCE.

In the Czech Republic, a wolf's bone was notched, dated back to about 30000 BCE.

1 liter = 33.814 ounces, so 2 liters = 67.628 ounces

Number of ounces per dollar:  

For the 2 liter bottle:  67.628 ounces / $1.99  =  33.98 ounces per dollar  

For the 20 ounce bottle:  20 ounces / $0.89  -  22.47 ounces per dollar

You get more ounces per dollar with the 2 liter bottle.

Let  x = number of text messages:

ATT plan:       25.00 + 0.10·x

Verizon plan:  1.35·x

To calculate when they will be the same:    25.00 + 0.10x  =  1.35x

Subtract 0.10x from both sides:                          25.00  =  1.25x

Divide both sides by 1.25:                                       20  =  x

For 20 text messages:  ATT cost =  25.00 + 0.10·20  =  25.00 + 2.00  =  27.00

                            Verizon cost =  1.35·20  =  27.00

Since  1 pound = 16 ounces,  then  4 pounds  =  4 x 16 ounces.

No. But standard deviation can be used to measure the amount of uncertainty.

Picture this:  you are trying to saw a group of boards by hand, each supposed to be 30 cm long.

You won't be able to saw them exactly 30 cm long; some will be a little longer, some will be a little shorter.

Standard deviation is a measurement of how close they are to being exactly 30 cm long. The smaller the standard deviation, the more precise your products are to each other (being the same size).

Uncertainty can refer to several things. It can refer to measuring your error in predicting the flip of a coin, the chance that it will rain tomorrow, or the chance that a particle will decay. 

That is a number; it does not have a standard deviation.

(5.8785 x 10^12) x (1.46 x 10^98)  =  (5.8785 x 1.46) x (10^12 x 10^98)

Use a calculator to multiply  5.8785 x 1.46.

To calculate  10^12 x 10^98  add the exponents to get  10^110.

So the answer is the answer of  (5.8785 x 1.46) x 10^110

The triangle proportionality theorem says that any line parallel to the base of the triangle that intersects the other two sides,  divides the other two sides into the same ratio.

Given triangle ABC with base BC, X on side AB, and Y on side AC:

     if  XY || BC,  then  AX/XB  =  AY/YC

10p - (3p-6) = 4(3p - 6)-8p

Use the distributive property:    10p - 3p + 6  =  12p - 24 - 8p

Simplify:                                          7p + 6  =  4p - 24

Subtract 4p from both sides:              3p + 6  =  -24

Subtract 6 from both sides:                      3p  =  -30

Divide both sides by 3:                              p  =  -10

10%  of  $295.00  is  0.10 x $295.00  =  $29.50

Final cost:  $295.00 - $29.50  =                            <-- the answer
