The missing options that makes up the distance formula between two coordinates are; (x₂ - x₁)² and d²
How to find the distance between two coordinates?
The formula for distance between two coordinates is;
d = √[(y₂ - y₁)² + (x₂ - x₁)²]
where;
(x₁, y₁) is the coordinate of the first point
(x₂, y₂) is the coordinate of the second point
Now, this distance formula can also be rewritten when we square both sides to get;
(y₂ - y₁)² + (x₂ - x₁)² = d²
Thus, the missing options that makes up the distance formula between two coordinates are; (x₂ - x₁)² and d²

Answer:
(1) 97
(2) 385
(3) 9604
Step-by-step explanation:
The (1 - <em>α</em>) % confidence interval for population proportion is:
The margin of error in this interval is:
The formula to compute the sample size is:
(1)
Given:
*Use the <em>z</em>-table for the critical value.
Compute the value of <em>n</em> as follows:
Thus, the minimum sample size required is 97.
(2)
Given:
*Use the <em>z</em>-table for the critical value.
Compute the value of <em>n</em> as follows:
Thus, the minimum sample size required is 385.
(3)
Given:
*Use the <em>z</em>-table for the critical value.
Compute the value of <em>n</em> as follows:
Thus, the minimum sample size required is 9604.
Answer:
x = -13
Step-by-step explanation:
Distribute:
8 - 6x + 10x - 15 = 20 - 5x
Combine like terms:
4x - 7 = 20 - 5x
Isolate Variable
-x = 13
-1(-x) = -1(13)
x = -13
Answer:
Step-by-step explanation:
C) Sarah is trying to say that 72 and 64 are opposite, if 68 is used as the starting point. So from the point 68, 72 is +4 and 64 is -4. 68 is the "baseline" or starting point
