The probability that a randomly selected American adult takes multivitamins regularly and works out regularly is 0.103
Step-by-step explanation:
p(Americans adults take multivitamins regularly) = 50% = 0.50
p(American adults work out regularly) = 20.6 = 0.206
p(Americans adults take multivitamins regularly and American adults work out regularly) = 0.50* 0.206 = 0.103
Thus, p(Americans adults take multivitamins regularly and American adults work out regularly) = 0.103
Answer:
The roots of the equation are
<h3>- 4 and 4</h3>
Step-by-step explanation:
First rewrite the expression
That's
x² - 16
16 = 4²
So we have
x² - 4² = 0
Using the identity
<h3>a² - b² = (a + b)(a - b)</h3>
Rewrite the expression
So we have
x² - 4² = 0 is
( x + 4)( x - 4) = 0
x + 4 = 0 x - 4 = 0
x = - 4 x = 4
The roots of the equation are
- 4 and 4
Hope this helps you
