NEED HELP WITH A MATH QUESTION
Lady_Fox [76]

Answer:

\dfrac{18}{5}

Step-by-step explanation:

The picture shows three isosceles tirangles with the same legs. The base of each triangle is 12 units, 5x-3 units and 17 units.

Since the angles at vertex of each isosceles triangles are 27°, 28° and 29°, then the lengths of the bases satisfy the double inequality

15<5x-3<17

Add 3 to this inequality

15+3<5x-3+3<17+3

18<5x<20

Divide it by 5:

\dfrac{18}{5}

you have a bag full of 17 marbles. Of those marbles, 3 are black. What is the probability that a marble chosen is not black
sdas [7]
Total number of marbles = 17

3 are black.

Not black = 17 - 3 = 14.

Probability of not black =          Number not black / Total

                                       =     14 / 17
