Answer:
Option B
Step-by-step explanation:
Although the difference is quite small (72 seconds—or just over a minute), the effect was statistically significant (P-value < 0.0001).
Since the P-value was less than 0.0001, the null hypothesis in this case can be rejected (H₀: ∪=12.3), concluding that the startup company has moderate/enough evidence that their AAA batteries last longer, on average.

Answer:
3
Step-by-step explanation:
There is one variable and its exponent is 3. The degree of the expression is the value of that exponent, 3.
Step-by-step explanation:
<em>=>(b*-b²)+(b*4b)-(b*3b)-(2*-b²)+(2*4b)-(2*3b)</em>
<em>=</em><em>></em><em>-b³</em><em>+</em><em>4</em><em>b</em><em>²</em><em>-</em><em>3</em><em>b</em><em>²</em><em>-</em><em>2</em><em>b</em><em>²</em><em>+</em><em>8</em><em>b</em><em>-</em><em>6</em><em>b</em>
<em>=</em><em>></em><em>-b</em><em>³</em><em>+</em><em>b²</em><em>-</em><em>2</em><em>b</em><em>²</em><em>+</em><em>2</em><em>b</em>
<em>=</em><em>></em><em>-b³</em><em>-</em><em>b²</em><em>+</em><em>2</em><em>b</em>
