Simplify.<br> (-8V2)(+1/2V32)

Hello!!

$\rule{300}{5}$

$\huge\blue{{\fbox{\tt{ANSWER:-\:}}}}$

$-32$

$\huge\red{{\underline{\overline{\textbf{MY\:EXPLANATION~!}}}}}$

Apply rule: $(-a) = -a$

$(-8\sqrt{2}) = - 8\sqrt{2}$

$= -8\sqrt{2}~\frac{1}{2}\sqrt{32}$

$\sqrt{2}~\sqrt{32} =\sqrt{64}$

$= -8\sqrt{64}~\frac{1}2}$

$\sqrt{64} = 8$

$= -8$ · $8$ · $\frac{1}{2}$

Multiply the numbers: $-~8$ · $8= -64$

$=-64$ · $\frac{1}{2} = -32$

$= -32$

Hope It Helps. . .

finlep [7]

Answer:

0.3157

Step-by-step explanation:

Given that according to a certain news poll, 71% agreed that it should be the government's responsibility to provide a decent standard of living for the elderly,

Let A be the event that it should be the government's responsibility to provide a decent standard of living for the elderly, and B the event that it would be a good idea to invest part of their Social Security taxes on their own

P(B) = 41%=0.41

A and B are independent

Hence P(both)= $0.77(0.41) = 0.3157\\$

the probability that a person agreed with both propositions

= Probability for both A and B

= P(A) P(B) since A and B are independent

= 0.3157
