Find the perimeter of OQR if OQ=6.5.<br> A.<br> 6.1<br> B.<br> 12.2<br> C.<br> 13<br> D.<br> 19.1
Svetach [21]

ANSWER


The correct answer is 19.1


EXPLANATION


The perimeter of triangle OQR is the sum of the distance around the triangle.



Thus,


Perimeter=|OQ|+|OR|+|RQ|



We can observe that two of the angles are equal.



The angles that are equal measures 62° each.



Therefore triangle OQR is an isosceles triangle. This means that



|OQ|=6.5=|OR|



Hence,



Perimeter=6.5+6.5+6.1




Perimeter=19.1 units.

Calculate the probability of needing at least 5 tosses of an unbiased coin to land a head.
Gnom [1K]

Answer:

0.03125

Step-by-step explanation:

If we have a fair coin the probability of landing a head is 50%.

We can think the question as what is the probability of landing four tails and then a head. That is we needed at least 5 tries to get a head.

Prob \{ T,T,T,T,H\}

Since this events are independent we can write it as

Prob \{ T\} \times Prob \{ T\} \times Prob \{ T\} \times Prob \{ T\} \times Prob \{ H\} =.5^5= 0.03125
