Considering the amount of PI (3.14) your equation would be written like this for the top portion

6x3.14ft^2
18.84ft^2

Now all you have to do is multiply 18.84ft by 2 giving you the answer of 37.68

Same thing for the circumference, almost

18.84ft with the height of 6ft.

Given. I would have to say Area of Base has the most volume<span />

Zina [86]

Answer:

The equation of the regression line is: $y~=~88.518 ~-~ 3.068 \cdot x$

Step-by-step explanation:

Linear regression is a linear approach to modelling the relationship between a dependent variable and one or more independent variables.

Let X be the independent variable and Y be the dependent variable. We will define a linear relationship between these two variables as follows:

$Y=bX+a$

We have the the following data:

$\begin{array}{c|cccccccccc}No. \:of \:absences,\:x&0&1&2&3&4&5&6&7&8&9\\Final \:grade, y&88.5&85.7&82.8&80.3&77.4&73.1&63.6&68.1&65.2&62.4\end{array}$

To find the line of best fit for the points, follow these steps:

Step 1: Find $X\cdot Y$ and $X\cdot X$ as it was done in the table.

Step 2: Find the sum of every column:

$\sum{X} = 45 ~,~ \sum{Y} = 747.1 ~,~ \sum{X \cdot Y} = 3108.8 ~,~ \sum{X^2} = 285$

Step 3: Use the following equations to find intercept a and slope b:

$\begin{aligned} a &= \frac{\sum{Y} \cdot \sum{X^2} - \sum{X} \cdot \sum{XY} }{n \cdot \sum{X^2} - \left(\sum{X}\right)^2} = \frac{ 747.1 \cdot 285 - 45 \cdot 3108.8}{ 10 \cdot 285 - 45^2} \approx 88.518 \\ \\b &= \frac{ n \cdot \sum{XY} - \sum{X} \cdot \sum{Y}}{n \cdot \sum{X^2} - \left(\sum{X}\right)^2} = \frac{ 10 \cdot 3108.8 - 45 \cdot 747.1 }{ 10 \cdot 285 - \left( 45 \right)^2} \approx -3.068\end{aligned}$

Step 4: Assemble the equation of a line

$\begin{aligned} y~&=~a ~+~ b \cdot x \\y~&=~88.518 ~-~ 3.068 \cdot x\end{aligned}$

The graph of the regression line is:

A jar contains 26 fluid ounces of spaghetti sauce how many cups of spaghetti sauce do 4 jars contain

qaws [65]

There are 8 fluid ounces in a cup.

First multiply 26 x 4 = 104
There are 104 fluid ounces in 4 jars of spaghetti sauce.

Now divide 104 by 8.
104/8 = 13

4 jars of spaghetti sauce contain 13 cups of spaghetti sauce.

Simplify the numerical expression (15 - 3) x 2 + 10

Kipish [7]

Answer:

Step-by-step explanation:

Using PEMDAS (parentheses, exponent, multiplication, division, addition, subtraction), we solve what's in the parentheses first, so the expression looks like: 12 x 2 +10.

Then since there aren't any exponents, we solve the multiplication problem in the expression: 24 + 10.

Which just leaves addition, which gives us our answer: 34

Hope this helps!
