7=x^2+20x+82
0=x^2+20x+75

What adds to 20 and multiplies to 75? 5 and 15.

x^2+5x+15x+75
x(x+5) 15(x+5)
(x+15) (x+5)

Zeroes are x= -5 and x= -15

$\sqrt{80} = \sqrt{2 * 2* 2* 2* 5} = \sqrt{2^{2}*2^{2}*5} = 2*2* \sqrt{5} = 4 \sqrt{5}$
Hope this helps.

Answer: $H_0:\mu=0.44\ ,H_a:\mu$

Step-by-step explanation:

Since we have given that

A very large study showed that aspirin reduced the rate of heart attacks by 44%.

we claim that they have a drug that will be more effective than aspirin.

so, our hypothesis would be

$H_0:\mu=0.44\\\\H_a:\mu$

So, it will be one tail test.

Hence, $H_0:\mu=0.44\\\\H_a:\mu$
