Answer:

0.25

Step-by-step explanation:

Probability = Number of favorable outcomes / Number of posssible

outcomes

There are 5 favorable outcomes (the 5 salamanders).

There are 20 posssible outcomes (the 5+3+12=20 total animals).

P (salamander) = \frac{5}{20} = 0.25

devlian [24]

Answer:

91.

Step-by-step explanation:

The least number will be a multiple of 7 while the number - 1 will be a multiple of 2,3 and 5.

2*3*5 = 30  but 31 is not a multiple of 7.

2*2*3*5 = 60 but 61  is not divisible by 7.

2*3*3*5 = 90 and 91 is divisible by 7.

The diagram tells us 3 things: the right angle and the two corresponding side measurements. Because the side measurements are corresponding, we can set a proportion:

6/9=9/15

If this proportion is true, it means the triangles are similar. If this proportion is impossible, it means the triangles are no similar.

To calculate this, we use cross multiplication.

6/9=9/15

6*15=9*9
90=81

90 does not equal 81 making this proportion impossible, which concludes that these two triangles are not similar.

I hope this helps! Please comment if you have any questions.
