Answer: 152.46 squared centimeters.

Step-by-step explanation:

The equation to find the area of the trapezoid is A = ½ (6.6 + 16.5) 13.2
Distribute ½ into (6.6 + 16.5) . A = (3.3 + 8.25) 13.2.
Add the numbers inside the parenthesis. A = 11.55 * 13.2
Multiply 11.55 * 13.2. A = 152.46.

Consider the following: A medical researcher wants to determine the effects of pH (a measure of alkalinity or acidity, with pure

Answer:

See below

Step-by-step explanation:

<h3>Continuation of the question</h3>

Data in the table:

PH 4 5 6 7 8 9 10 11

Bacteria 116 120 131 136 141 151 148 163

Create a scatter plot to represent the data: Based on the data and your scatter plot, what do you think a good linear function would be to represent the data?

<h3>Solution</h3>

See attached for scatter plot

We can see the chart is close to linear function. Let's build one based on data in the table

The line will be in the form of:

y = mx + b

If we use two points and get the equation

(4, 116) and (8, 141)

Finding the slope:

m = (141-116)/(8-4) = 25/4 = 6.25

Then, finding y-intercept:

116 = 6.25*4 + b
b = 116 - 25 = 91

So the line is:

y = 6.25x + 91

Note: This is approximate best fit graph and it is attached as well. Exact formula for the line is built by using different method and is very close to the one above
