The table shows data from a travel agency, representing the number of guests on a trip (x) and the estimated dollar
Arlecino [84]

The slope of the best fit for the 3 given points is 500, so the correct option is b.

<h3>How to find the slope?</h3>

Remember that for a line that passes through two points (x₁, y₁) and (x₂, y₂) the slope is:

s = \frac{y_2 - y_1}{x_2 - x_1}

With the 3 given points we can find 3 slopes, and then we will need to find the average of these 3.

The 3 points are: (3, 2,750), (6, 4,200), and (9,5,750)

Then the 3 slopes are:

s_1 = \frac{4,200 - 2,750}{6 - 3} = 483.3\\\\s_2 =  \frac{5,750 - 2,750}{9 - 3} = 500\\\\s_3 =  \frac{5,750 - 4,200}{9 - 6} = 516.7

The average slope is:

S = (483.3 + 500 + 516.7)/3 = 500

So the correct option is b.

Find the mean age of the swimmers on the team. ​
kap26 [50]
<h3>Answer:  10</h3>

============================================

Work Shown:

First add up all the ages

9+13+9+10+10+9+10+10+11+9 = 100

Then divide that sum by 10, since there are 10 values we added up

100/10 = 10

The average age is 10 years old.

Suppose you like to keep a jar of change on your desk. Currently, the jar contains the following:
antoniya [11.8K]

Answer:

The probability is 435/6,806

Step-by-step explanation:

Firstly, the total number of coins in the jar is

13 + 15 + 29 + 26 = 83

The probability of selecting a dime is 15/83

Now we want to grab a nickel

Since we already selected a dime and we did not replace it, the number of total coins in the jar will be 83-1 = 82

So the probability of selecting a nickel this time is

29/82

So the total probability of the event in the described order is;

15/83 * 29/82

= 435/6,806
