Travka [436]

<u>Answer:</u>

The correct answer option is 43%.

<u>Step-by-step explanation:</u>

We are given that 70% of students have blue eyes, 45% have dark hair, and 30% have blue eyes and dark hair.

We are to find the probability of a student getting selected will have dark hair with blue eyes.

P(D|B) = P(D∩B) / P(B)

Substituting the given values in it to get:

P(D|B) = 0.3 / 0.7 = 0.428

Rounding it to the nearest whole percent we get:

0.428 × 100 = 42.8% ≈ 43%

Vladimir79 [104]

Given


Sofia cuts a piece in the shape of a kite for an art project  

top two sides measure 20 cm each  

bottom two sides measure 13 cm each.  

One diagonal, EG, measures 24 cm


Find out the length of the other diagonal, DF.


To proof  

As given in the question and also shown in the diagram shown below


DE = EF = 20cm


DG = GF = 13cm


EG = 24cm


DF = ?


In kite shape


One diagonal is the perpendicular bisector of the other diagonal.


i.e EG is the perpendicular bisector of DF


i.e EG is divided into two equal parts


thus EA = AG = 12cm


in Δ EAF


By applying the pythagorus theorem


we have


EF² = FA²+ EA²


20² = 12² + FA²


400 -144 = FA²


256 =FA²


\sqrt{256} =FA


16cm = FA


Now in Δ DAG


DG² = AG² + DA²


13² = 12 ²+ DA²


169 -144 = DA²


25 = DA²


\sqrt{25} =DA


5cm = DA


Thus diagonal DF = DA + FA


= 5 + 16


= 21cm


Hence proved
