To solve, simply do this:

(\frac{1}{2}^3)-(\frac{3}{4} )^2\\\\\frac{1}{2} *\frac{1}{2} *\frac{1}{2} *\frac{1}{2} \\\\\frac{1}{8} -(\frac{3}{4})^2\\\\\frac{1}{8}-\frac{9}{16}\\\\=\frac{-7}{16}

Then you'll get the answer, -7/16

A string of holiday lights contain 20 bulbs. the bulbs are wired in series, so that if any bulb fails, the whole string will go
sergij07 [2.7K]
This is equal to the probability that no light fail.  Probability of  one light not failing = 0.98.

P(no light fails) = 0.98^20  =   0.67  or 67%   to nearest percent.

Can you help me figure this out
Rasek [7]

Answer:

Avocados- 9

Onions- 7.5 or 7 1/2

Lime Juice-  2.25 or 2 1/4

Step-by-step explanation:

Since the original recipe is for 8 people, and 24 is a product of 8, all you have to do is multiply the ingredients you have by 3.

3*3 is 9

2 1/2= 2.5 2.5*3 is 7.5 or 7 1/2

3/4= 0.75 0.75*3 is 2.25 or 2 1/4

I hope this helped you! If you have any other questions, ask me! :)
