Answer:
Part 1)
Part 2) The answer in the procedure
Step-by-step explanation:
Part 1)
we know that
Applying the Pythagoras Theorem
we have
substitute the values
Part 2) Transform each side of the equation to determine if it is an identity
The left side is equal to the right side
therefore
Is an identity

The first table shows <span>a two-way conditional frequency table for gender. If you look at the table of data, the column totals are equal to 1. This indicates that the condition is between which gender wants to visit either of the two places. A two-way conditional frequency is used to determine the relationship of a variable to another variable with different categories.</span>
Answer:
Burger meal costs $8 and hot dog meal costs $6.
Step-by-step explanation:
To find the price per meal, write a system of equations.
Let b = cost of a burger meal and d = cost of a hot dog meal.
Write the equation 3b + 4d = 48 for the Woodsons.
Write the equation 6b + 2d = 60 for the Barkers.
Use elimination to solve the system. Begin by making the coefficients of one variable the same in both equations by multiplying 3b + 4d = 48 by 2.
2(3b + 4d = 48) ----> 6b + 8d = 96
Stack the equations and subtract.
6b + 8d = 96
- 6b + 2d = 60
------------------------
6d = 36
d = 6
Substitute d = 6 into one equation to solve for b.
3b + 4(6) = 48
3b + 24 = 48
3b = 24
b = 8
