Check explanation
Step-by-step explanation:
There are two ways to solve this, I'm not sure which way is the correct one:
1. Solving with 3.14
V=πr²h
V=(3.14)(13)²(17)
V=(3.14)(169)(17)
V=(3.14)(2873)
V=9021.22
9021.22 rounded to the nearest hundredth is 9021.22
2. Solving with π (I used a calculator to solve with π)
V=πr²h
V=π(13)²(17)
V=π(169)(17)
V=π(2873)
V=9025.79569376
9025.79569376 rounded to the nearest hundredth is 9025.8
The question says to use 3.14 so it can be method 1, but the question also asks to round to the nearest hundredth and method 2 leads me to actually being able to round so it can be suspected that method 2 is the correct way. Whichever you think is best can be chosen and sorry if this isn't a clear answer! I hope it does help.

Child = $5.70
Adult = $9.80
- We can conclude that the amount of adult is double the amount of child tickets bought. (total of $556.60)
For this, you will need to divide the total amount by two and draw a tree chart with each of the numbers to get the seperation of the two. I would find out how many 9.80s or 5.70s go into $56.60 so you'll just have $500
The regression equation which correctly models the data in this table is y = 1.49x - 107.5,
<h3>How to determine the regression equation?</h3>
From the table of data values, we have the following parameters:
∑x = 632
∑y = 404
∑x² = 80.142
∑xy = 51.448
Mathematically, the regression equation is represented by the following slope equation:
y = Bx + A
Next, we would determine A by using this expression:
A = (∑y·∑x² - ∑x·∑xy)/(n∑x² - (∑x)²)
A = (404×80,142 - 632×51,448)/(5×∑x² - (632)²)
A = (32,377,368 - 32,515136)/(5×80142 - 399,424)
A = -137,768/1286
A = 107.5
For B, we have:
B = (n∑xy· - ∑x·∑y)/(n∑x² - (∑x)²)
B = (5×51,448 - 632×404)/(5×∑x² - (632)²)
B = 1.49.
y = Bx + A
y = 1.49x - 107.5
