only the first statement is true - it is the experimental probability. the rest is incorrect: the ratio is not the number of trials; the theoretical probability should be 0.5 (for unbiased coins); ratio never represents a number of occurences.
15) 4m^2
17)9n^6
198a^2 (^ = power of)
Answer:
The answer is -2/3.
Hope this helps and if you could mark as brainliest. Thanks!
It would cost $105 because if you do 13+13+13= 39
22+22+22= 66
66+39= 105.
The Traingle XYZ and ACB are similar triangles. tanX = tanA = 5 over 2 and 5 tenths,
AC = 2 * XY; CB = 2 * YZ
<h3>What is an equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Triangle XYZ was dilated by a scale factor of 2 to create triangle ACB, hence XYZ and ACB are similar triangles.
Angles Y and C both measure 90 degrees, and angles A and X are congruent. Hence:
tanX = tanA = 5 over 2 and 5 tenths
AC = 2 * XY; CB = 2 * YZ
