Which shows a perfect square trinomial?
anastassius [24]
The answer is <span>c. 16x2 + 24xy + 9y2.

Since we need trinomial (three term expression) choices a and b are incorrect because they have only two terms.

So, our square trinomial is a</span>² + 2ab + b² or a² - 2ab + b²
a² + 2ab + b² = (a + b)²
a² - 2ab + b² = (a - b)²

Let's check choices c and d:
c) 16x² + 24xy + 9y²
a² = 16x²
a² = (4x)²
a = 4x

b² = 9y²
b² = (3y)²
b = 3y

a² + 2ab + b² = (4x)² + 2 * 4x * 3y + (3y)² = 16x² + 24xy + 9y²
CORRECT

d) 49x² - 70xy + 10y²
a² = 49x²
a² = (7x)²
a = 7x

b² = 10y²
b² = (y√10)²
b = y√10

a² + 2ab + b² = (7x)² + 2 * 7x * y√10 + (y√10)² = 49x² + 14xy√10 + 10y²
INCORRECT

So, c) is correct answer

Answer:

See explanation for answer, hope it helps

Step-by-step explanation:

Toss; 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

Total number of heads so far; 1, 1, 1, 1, 2, 3, 4, 4, 4, 5

Relative Frequency of heads so far;

\frac{1}{1} = 1.0 = 100%

\frac{1}{2} = 0.5 = 50%

\frac{1}{3} = 0.33 = 33%

\frac{1}{4} = 0.25 = 25%

\frac{2}{5} = 0.4 = 40%

\frac{3}{6} = 0.5 = 50%

\frac{4}{7} = 0.57 = 57%

\frac{4}{8} = 0.5 = 50%

\frac{4}{9} = 0.44 = 44%

\frac{5}{10} = 0.5 = 50%

Total number of tails so far; 0 1, 2, 3, 3, 3, 3, 4, 5, 5

Relative Frequency;

\frac{0}{1} = 0 = 0%

\frac{1}{2} = 0.5 = 50%

\frac{2}{3} = 0.66 = 66%

\frac{3}{4} = 0.75 = 75%

\frac{3}{5} = 0.6 = 60%

\frac{3}{6} = 0.5 = 50%

\frac{3}{7} = 0.42 = 42%

\frac{4}{8} = 0.5 = 50%

\frac{5}{9} = 0.55 = 55%

\frac{5}{10} = 0.5 = 50%
