Step-by-step explanation:
Answer:
B
Step-by-step explanation:
hope it is well understood
1. -5x^10, because 4-9 is 5 and you don't do anything do the exponents when subtracting.
2. 9x^2-12x-6, quadratic trinomial
3. 5.5x^2+5.5x^2-9.2x+9.9x+9.6+1.3=
11x^2+0.7x+8.2
Using the Empirical Rule, approximately 95% of the area under the whole curve is in the two tails.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Hence, approximately 95% of the area under the whole curve is in the two tails.

Answer:
A = 64π ≅ 200.96
Step-by-step explanation:
area of a circle can be found with the equation
A = πr²
they give us that the diameter is 16, so we know the radius r is 8
then we just plug into the equation
A = π(8)² = 64π
if you want to plug in 3.14 for π, you'll get approximately
64π = 200.96
