Answer:
2nd degree
Step-by-step explanation:
The 95% confidence interval for the population will be 0.312 < SD < 0.885.
<h3>How to calculate the confidence interval?</h3>
From the information given, it should be noted that the values listed below are waiting times of customers at the Jefferson Valley Bank, where customers enter a single waiting line that feeds three teller windows.
The degree of freedom will be:
= 9 - 1 = 8
The number illustrated is 9 and the standard deviation is 0.462.
The 95% confidence interval will be'
= ✓(9 - 1) × 0.462²/17.53) < ✓(9 - 1( × 0.462)²/2.28
= 0.312 < SD < 0.885.

Answer:
Jose made $207.20
Step-by-step explanation:
We have been given that Jose bought 20 shares of Netflix at the close price of $117.98.
Hence, cost price of the shares = 20 × 117.98 = $2359.60
Now, Jose sells all of his shares at $128.34.
Hence, selling price of the shares = 20 × 128.34 = $2566.8
Therefore, the profit is given by
Profit = selling price - cost price
Profit = 2566.80 - 2359.60
Profit = $207.20
Therefore, Jose made $207.20

Answer:
3 coefficients in this expression are: -2x, 5y and 9 (natural number)
Step-by-step explanation:
-6x + 5y + 4x + 9
= -6x + 4x + 5y + 9
= -2x + 5y + 9
3 coefficients in this expression are: -2x, 5y and 9 (natural number)
