Suppose that a poll finds that 31.9​% of taxpayers who filed their tax return electronically​ self-prepared their taxes. If thre
Aneli [31]

Answer: 0.0325

Step-by-step explanation:

Binomial probability distribution formula for x successes in n trials:-

P(X=x)=^nC_x\ p^x\ (1-p)^{n-x}, where n is the number of trials , p is the probability of success.

Given : The probability that taxpayers who filed their tax return are electronically​ self-prepared their taxes : p= 0.319

If three tax returns submitted electronically are randomly​ selected, then the probability that all three were​ self-prepared is given by :-

P(X=3)=^3C_3\ (0.319)^3\ (1-0.319)^{3-3}\\\\=(1) (0.319)^3(1)\\=0.032461759\approx0.0325

Hence, the probability that all three were​ self-prepared =0.0325

Harman [31]

Answer:

2^{4} = x^{4} - 3

Step-by-step explanation:

recall for a logrithimic expression,

log_{b} (c)=a, can be expressed as b^{a}  = c

hence for our question

log_{2} [ (x^4) -3] = 4

can be expressed as

2^{4} = x^{4} - 3

What is 0.22222222 in bar notation
dsp73

Answer: Hello, Maybe this can help you figure out it This is called bar notation. Bar notation is an easier way to write a repeating number by putting a line, or bar, over the repeating numbers. But using bar notation, you would say 1 / 7 = 0.142857 with a line over those numbers to show that they repeat over and over.
