Answer:

18

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Given

(- \frac{1}{2}\sqrt{2} )( - 6\sqrt{18})

= - \frac{1}{2} × - 6 × \sqrt{2} × \sqrt{18}

= 3 × \sqrt{36}

= 3 × 6

= 18

The length of an ant is 0.52 inches, what is its length as seen through her binoculars?

The binocular is set to enlarge the object 10 times their actual size.

Kazeer [188]

Answer:

Step-by-step explanation:

The complete question is given thus:

Suppose that computer literacy among people ages 40 and older is being studied and that the accompanying tables describes the probability distribution for four randomly selected people, where x is the number that are computer literate. Is it unusual to find four computer literates among four randomly selected people?

x      P(x)

0     0.16

1      0.25

2     0.36

3      0.15

4      0.08

  • Yes
  • No

ANSWER:

The odds that this will occur according to the chart are 0.08, or 8%, so although this is unlikely, it's not terribly unusual.

⇒ NO

So from the following we can say it is not unusual to find four (4) computer literates among four randomly selected people.

ok, so P(1) + P(2) + P(3) + P(4) + P(0)  = 0.16+0.25+0.36+0.15+0.08 = 1

Whereas the chance of finding four (4) out of four (4) computer iteration is low when compared to other factors.

cheers i hope this helped  !!
