Margot is studying the yield of bushels of wheat in comparison to the amount of rainfall, in inches, that occurs. She finds the

linear regression equation to be y = 47.3 +0.78x.
If an additional 1 inch of rain fell, how many MORE bushels of wheat would be yielded?

Let y be the yield of bushels of wheat in comparison to the amount of rainfall
Let x be the amount of rainfall that occurs (in inches)

If the linear regression equation is y = 47.3 + 0.78x, then per inch of rainfall will yield an addition 0.78 bushels (plugging into x the additional inches of rainfall). 

Therefore, on the first inch of rainfall, y = 48.08. 
On the second inch of rainfall, y = 48.86.

And so on.

Leona [35]

Answer:

75+(-50)=75-50

Step-by-step explanation:

-let x be the profit made last week and y be the profit made this week.

-The two week profit/ loss is given as:

Profit=x+y

#We substitute actual values to calculate the profit/loss made:

Profit=x+y\\\\=75+(-50)\\\\=75-50\\\\=\$25

Hence, the two-week combined profit is $25.00

Suppose that 3 balls are chosen without replacement from an urn consisting of 5 white and 8 red balls. Let Xi equal 1 if the ith
Katarina [22]

Answer:

The joint probability mass function table is provided below.

Step-by-step explanation:

The experiment consist of drawing 3 balls from an urn containing 5 white and 8 red balls.

The random variable <em>Xi</em> is defined as follows:

<em>Xi</em> = 1; if the ith ball is white

<em>Xi</em> = 0; otherwise.

Then <em>X</em>₁ = the 1st ball is white and <em>X</em>₂ = the 2nd ball is white.

The sample space is as follows:

S = {(X₁ = 0, X₂ = 0), (X₁ = 0, X₂ = 1), (X₁ = 1, X₂ = 0), (X₁ = 1, X₂ = 1)}

Compute the probability of each event in the sample space as follows:

P(X_{1} = 0, X_{2}= 0)=\frac{8}{13} \times\frac{7}{12}=\frac{14}{39}

P(X_{1} = 0, X_{2}= 1)=\frac{8}{13} \times\frac{5}{12}=\frac{10}{39}

P(X_{1} = 1, X_{2}= 0)=\frac{5}{13} \times\frac{8}{12}=\frac{10}{39}

P(X_{1} = 1, X_{2}= 1)=\frac{5}{13} \times\frac{4}{12}=\frac{5}{39}

The joint probability mass function table is provided below.
