To answer the question we need to know if we replaced or not. 

Lets calculate the 2 probabilities. 

1, No replacement
first draw is an ace P=4/52
2nd draw is an ace P=3/51
Both are A: P=4/52 * 3/51 = 0,0045

2, With replacement
Both draws P=4/52
Both A: P =(4/52)^2 = 0,0059

So we know that it was with replacement. 
This means theat the two events are independent. (both draws have 4/52 chance, not affecting eachother)

There are 175 baskets of fruit in the supermarket. 13 baskets of them are bananas. What percent of the baskets are not bananas?
alexira [117]

Based on the information given the percent of the baskets that are not bananas is: 92.57%.

<h3>Percent of the baskets that are not bananas </h3>

Using this formula

Percentage=(Number of baskets of fruit-Basket of bananas)/Number of baskets of fruit

Let plug in the formula

Percentage=(175-13)/175

Percentage=162/175×100

Percentage=92.57%

Inconclusion the percent of the baskets that are not bananas is: 92.57%.

Coffee is a leading export from several developing countries. When coffee prices are high, farmers often clear forest to plant m
Marianna [84]

Answer:

The plot shows a positive linear association. Price is the explanatory variable.

*See attachment for the scatterplot of the data

Step-by-step explanation:

The rate of deforestation is dependent on the price of coffee. Therefore, the explanatory variable is the price of coffee, which affects rate of deforestation.

The response variable is the rate of deforestation. The rate of deforestation is influenced by the price of coffee.

When plotting a scatter plot, the values for the explanatory variable are plotted on the x-axis, while the response variables are plotted on the y-axis.

The data given below is what we would use in plotting the scatterplot shown in the attachment:

Explanatory variable, X, (Price, cents per pound) => Response variable, Y, (deforestation, %)

25 => 0.31

49 = > 1.69

60 => 1.66

55 => 1.7

68 => 3.31

The scatterplot graphed as shown in the attachment shows a positive linear relationship between price of coffee and rate of deforestation. As price increases, rate of deforestation also increases.
