By intuition, the function of y with respect to x will be:

y = 4x

You can prove this by substitute in each pair of values of x and y

So the constant of relationship is 4

Write an equation in slope-intercept form for the line that passes through the given point and is parallel to the graph of the g

krok68 [10]

Answer:

Step-by-step explanation:

The slope of the line is m = -5

4 is your x1

-3 is your y1

Plug into the equation y - y1 = m(x - x1)

y + 3 = -5(x - 4)

y + 3 = -5x + 20

-3 -3

y = -5x + 17

Using the data: 2, 2, 3, 3, 3, 4, 5, 6, 6, 19 What is Q1 and Q3

Anettt [7]

Answer:

$Q_1=2$

$Q_3=6$

Step-by-step explanation:

Notice that we already have the data sorted from least to greatest.

Now to find Q1 and Q3 we can use the following formulas

For a set of data ordered from least to greatest of the form $X_1, X_2, ..., X_n$

Where n is the total number of data

$Q_1=X_{\frac{1}{4}(n+1)}$

In this case $n=10$

So:

$Q_1=X_{\frac{1}{4}(10+1)}$

$Q_1=X_{2.75}$

Round the nearest whole and get:

$Q_1=X_{3}$

$Q_1=3$

For Q3 we have:

$Q_3=X_{\frac{3}{4}(n+1)}$

$Q_3=X_{\frac{3}{4}(10+1)}$

$Q_3=X_{8.25}$

Round the nearest whole and get:

$Q_3=X_{8}$

$Q_3=6$

medicine is administered at a rate of 6.5 mg per kilograms of body weight. how much should be administered to a child who weighs

alexandr402 [8]

$\bf \begin{array}{ccll}
\stackrel{mg}{medicine}&\stackrel{kg}{weight}\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
6.5&1\\
x&50
\end{array}\implies \cfrac{6.5}{x}=\cfrac{1}{50}\implies \cfrac{6.5\cdot 50}{1}=x\implies 325=x$
