Where,
predicted value of lead content when traffic flow is 15.


Calculating thet-critical value
The lower predicted value 

When
of CI use as the expected lead content:

Given the equation:

You know that a lab technician finds that a sample of fluid has this pH:

Then, in order to find the hydrogen ion concentration of the fluid, you need to follow these steps:
1. Substitute the pH given in the exercise into the equation:

Multiply both sides by -1:

2. Solve for:

Remember that, by definition:

In this case, you can identify that:

Hence, substituting values and simplifying, you get:

Therefore, the answer is:
Answer:
210 yd²
Step-by-step explanation:
If we rotate the shape we get a right angle triangle with a hypotenuse of 29 yd :
The area of a right angle triangle is given by the formula :
A =
Substituting the 2 values given in diagram gives us :
A =
= 420÷2 = 210
Our units will be yd² as we are dealing with area
