I apologize for the oversight. Let's solve it and provide the answer.
Step-by-step explanation :
1. **Standard Error Calculation :
\[ SE = \frac{\sigma}{\sqrt{n}} \]
\[ SE = \frac{25.3}{\sqrt{215}} \]
\[ SE \approx 1.7292 \]
2. **Z-Score Calculation:**
\[ z = \frac{X - \mu}{SE} \]
\[ z = \frac{197.2 - 195.5}{1.7292} \]
\[ z \approx 0.9836 \]
3. Finding the Probability :
To find the probability that the sample mean is greater than 197.2, we need to find the area to the right of the z-score in the standard normal distribution table.
For \( z \approx 0.9836 \), the area to the left is approximately \( 0.8374 \).
Since we want the area to the right (the probability the sample mean is greater than 197.2), we need to subtract that value from 1 :
\[ P(X > 197.2) = 1 - 0.8374 \]
\[ P(X > 197.2) = 0.1626 \]
Answer : The probability that the sample mean is greater than 197.2 is approximately \( 0.1626 \) or \( 16.26\% \).

Answer: Correlation there may have been other reasons why she played better .
Step-by-step explanation:
Given statement : "Michele watched videos of other soccer teams' plays, and she played better against those teams."
There are two things which were happening at the same time "one Micheal watched videos of other soccer teams and one she played better against those teams". It shows they are correlated perhaps there may have been other reasons why she played better but there is no casual relationship between them because occurrence of first thing did not cause the second thing to happen .

Answer:
A polynomial with complex coefficients of degree n has n complex roots, counted with multiplicity.
Step-by-step explanation:
We are given a polynomial p(x) in the question with degree n.
The degree n means the n is the highest power of variable in the given polynomial.
The equation:
Fundamental theorem of Algebra
- The Fundamental theorem of Algebra states that a a polynomial of degree n will have n roots of the equation.
This can further be explained as:
- A polynomial with complex coefficients of degree n has n complex roots, counted with multiplicity.

The length of the deck is (5 + 2x) .
The width of the deck is (4 + 2x) .
If the deck didn't have that big hole in the middle where the pool is,
then its area would be
(5 + 2x) · (4 + 2x) .
When you multiply that all out, you get Area = 4x² + 18x + 20
and the question tells us that the area of the whole big rectangle is 90 yds² .
So we can write
4x² + 18x + 20 = 90 .
Subtract 90 from each side: 4x² + 18x - 70 = 0
Divide each side by 2 : 2x² + 9x - 35 = 0
You can use the quadratic equation to solve that and find out that
x = 2.5 yards, and that's what the question is asking you.

That makes the deck 10 yds high and 9 yds wide.
Total area of the whole big rectangle, (deck + pool ), = 90 yds².
