Answer:
2.5
Step-by-step explanation:
If you know two other sides of the right triangle, it's the easiest option; all you need to do is apply the Pythagorean theorem:
a² + b² = c²
if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root:
a = √(c² - b²)
if leg b is unknown, then
b = √(c² - a²)
for hypotenuse c missing, the formula is
c = √(a² + b²)

Answers:
Rate of change = -5
Initial value = 25
Step-by-step explanation:
Each time x increases by 2 (eg from x = 1 to x = 3), the value of y drops by 10 (eg from y = 20 to y = 10)
Therefore the slope is...
slope = rise/run = (change in y)/(change in x) = -10/2 = -5
slope = -5
So each time x increases by 1, y will decrease by 5
Flip things around: each time x decreases by 1, y will increase by 5
So the pair (x,y) = (1,20) shown in row 1 of the table leads to (0,25) based on the rule above. Another way to see this is to plug m = -5, x = 1 and y = 20 into y = mx+b and solve for b to get b = 25
The length of the shortest side of the triangle in discuss is; x = 20 in.
<h3>What is the length of the shortest side of the triangle as given in the task content?</h3>
It follows from the task content that the length of the shortest side can be assumed to be; x in.
Therefore, the perimeter of the triangle is as follows;
Perimeter = x +(x+1) + (x+2)
63 = 3x +3
60 = 3x
x = 20 in.

Answer:
An null hypothesis is one that states there is no statistically significant relationship between two variables or a position that states something is not happening
An alternative hypothesis is one that states there is a statistically significant relationship between two variables or a position that states something is happening.
(a)
μ = 3800
μ > 3800
(b)
μ = 3800
μ < 3800
