Calculate the m angle CLA , given m arc AC = 160° and m arc AKC = 200°.
crimeas [40]
<span>When two tangent lines intersect, they form an angle that equals
one half (larger intercepted arc minus the smaller </span><span>intercepted arc)

So, angle CLA = (1/2) (200 -160)
</span><span>Angle CLA = (1/2) (40)
</span><span>Angle CLA = 20 degrees

A random number from 1 to 5 is selected
shutvik [7]

Answer:

Relative frequency of selecting a 2 = 8/50 = 0.16

Relative frequency of selecting a 3 = 14/50 = 0.28

Step-by-step explanation:

When we have a given experiment with given outcomes (such that each time that we perform the experiment, one outcome happens) the relative frequency of a given outcome is the quotient between the number of times that that outcome happened, and the total number of times that the experiment was performed.

Here the experiment is selecting a random number between 1 and 5, and it is performed 50 times.

Out of these 50 times, the outcome "2" appears 8 times.

Then the relative frequency of selecting the number 2 is:

f(2) = 8/50 = 0.16

And of these 50 experiments, the outcome "3" appears 14 times.

Then the relative frequency of selecting the number 3 is:

f(3) = 14/50  = 0.28

UkoKoshka [18]

Answer:

- 4\sqrt{2}

Step-by-step explanation:

Using the rule of radicals

\sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

Simplify \sqrt{18} using this rule

\sqrt{18}

= \sqrt{9(2)}

= \sqrt{9} × \sqrt{2} = 3\sqrt{2}

Then

- 2\sqrt{18} + 2\sqrt{2}

= - 2(3\sqrt{2} ) + 2\sqrt{2}

= - 6\sqrt{2} + 2\sqrt{2}

= - 4\sqrt{2}
