I think it is 17.50 because if you multiply $.50 by 7 you get $3.50. Then you multiply $3.50 by the 5 days to get $17.50

3. The weights of apples in a shipment from Al's Orchards are normally distributed with a mean of 142 grams and a standard devia

Kamila [148]

The z scores corresponding to the mean weight of a rotten apple relative to the apples from either orchard are, respectively,

$\dfrac{142-156}9\approx-1.56$

$\dfrac{165-156}{13}\approx0.69$

The mean for the standard normal distribution is 0, which means that z scores closer to 0 represent data points that are more likely to occur. Therefore it's reasonable to believe that rotten apples occur more often in shipments from Zippy's.

Definition of bivariate data

zubka84 [21]

Answer:

In statistics, bivariate data is data on each of two variables, where each value of one of the variables is paired with a value of the other variable. ... For example, bivariate data on a scatter plot could be used to study the relationship between stride length and length of legs.

Do I have to solve this before graphing it and if so how do I go about it?

Given the System of Equations:

$\begin{cases}y=4x-1 \\ \\ y=x-4\end{cases}$

The exercise asks for solving it graphically. Then, in this case, you need to graph both lines in order to determine the solution of the system.

In order to graph it, you can find the x-intercepts and the y-intercepts:

1. It is important to remember the Slope-Intercept Form of the equation of a line:

$y=mx+b$

Where "m" is the slope of the line and "b" is the intercept.

In this case, you can identify that the y-intercept of the first line is:

$b_1=-1$

And the y-intercept of the second line is:

$b=-4$

2. By definition, the value of "y" is zero when the line intersects the x-axis.

Then, you need to substitute the following value of "y" into each equation and then solve for "x", in order to find the x-intercept of each line:

$y=0$

- For the first line, you get:

$\begin{gathered} y=4x-1 \\ 0=4x-1 \\ 1=4x \\ \\ \frac{1}{4}=x \\ \\ x_1=0.25 \end{gathered}$

- For the second line, you get:

$\begin{gathered} y=x-4 \\ 0=x-4 \\ 4=x \\ x_2=4 \end{gathered}$

3. Now you know that the first line passes through these two points:

$(0.25,0);(0,-1)$

And the second line passes through these two points:

$(4,0);(0,-4)$

4. Knowing those points, you can graph the lines:

Notice that the line intersect each other at

Use the linear combination method to solve the system of equations. Explain each step of your solution. 2x-3y=13 4x-y=-9

Tems11 [23]

2x -3y = 13

4x -y = -9

Multiply the second equation by -3 to make the coefficient of Y opposite the first equation.

4x -y = -9 x -3 = -12x + 3y = 27

Now add this to the first equation:

2x -12x = -10x

-3y +3y = 0

13 +27 = 40

Now you have :

-10x = 40

Divide each side by -10:

x = 40 / -10

x = -4

Now you have a value for x, replace that into the first equation and solve for y:

2(-4) - 3y = 13

-8 - 3y = 13

Add 8 to both sides:

-3y = 21

Divide both sides by -3:

y = 21/-3

y = -7

Now you have X = -4 and y = -7

(-4,-7)
