1) Which ratio is equivalent to [tex] \frac{4}{16} [tex]?
[tex] \frac{4}{16} * 2 = \frac{8}{32} [tex], or
8:32.
2) Write the ratio as a unit rate [tex] ( \frac{286miles}{5 \frac{1}{2} hours} ) [tex]
Set the equation up like this:
[tex] \frac{286miles}{5 \frac{1}{2} hours} = \frac{Xmiles}{1 hour}\\
286*1=(5 \frac{1}{2})*x\\
286 = \frac{11x}{2}\\
11x= 572 [tex]
x =
52 [tex] \frac{miles}{hour} [tex]

The correlation coefficient of the data provided is -0.52.
<h3>What is the correlation coefficient?</h3>
Correlation is a measure that is used in statistics to determine the linear relationship that exists between two variables. Correlation can be positive, negative or zero.
Positive correlation is when two variables move in the same direction. Negative correlation is when two variables move in opposite directions. Zero correlation is when there is no relationship between the variables.
Correlation can be determined using a financial calculator. When the financial calculator is used, the correlation coefficient is -0.52

Answer:
<h2>
</h2>
Step-by-step explanation:
To find y when x=4, we must first find the relationship between them
The statement
y varies directly with x is written as
<h3>
</h3>
where k is the constant of proportionality
From the question
when y = 1/5
x = 3
Substitute the values into the above formula and solve
That's
<h3>
</h3>
So the formula for the variation is
<h3>
</h3>
From the question
when x = 4
<h3>
</h3>

We know the side relations of a right angled Triangle (that is Pythagoras therom)
now, let the missing side be x
- Hypotenuse² = sum of squares of other legs
that is ~
The correct choice is ~ B
Answer:
6 and 30
Step-by-step explanation:
n + 24
(n + 24) ÷ n = 5
n + 24 = 5n
24 = 4n
6 = n
Check
30 – 6 = 24
30 ÷ 6 = 5
