What's the REAL square root of pi?

1 answer:

5 0

Every positive number has two square roots. Since pi itself is irrational, you can be sure that its square roots are also irrational, so they can't be written exactly using digits. They're roughly +1.77245... and -1.77245... (both rounded).

SCORPION-xisa [38]

Answer:

The probability distribution for x:"number of children per family for this income group" is:

$\text{P(x=0)}=0.15\\\\\text{P(x=1)}=0.35\\\\\text{P(x=2)}=0.45\\\\\text{P(x=3)}=0.05\\\\$

Step-by-step explanation:

With the information given we have the relative frequencies of each category.

We know:

$\text{P(x=0)}=0.15\\\\\text{P(x=1)}=0.35\\\\\text{P(x=2)}=0.45\\\\\text{P(x=3)}=0.05\\\\$
