Answer:
Two
Step-by-step explanation:
The table is saying that, if Sandra swam enough races, she should expect to get 20 firsts, 12 seconds, 6 thirds, and two no placements.
Her expected value of points will be the average (mean) of all the points awarded for each race.
The average is the total number of points divided by the number of races.

The simulation says that, if she swam 40 races, she should expect to earn a total of 90 points.

She can't win a fraction of a point, so she can expect to win two points in her first race.

Answer:
y = 4x + 7
Step-by-step explanation:
the equation for a line is y = mx+b
the y intercept is (0,7)
so in the equation x= 0 and y= 7 and the slope is m, thus m= 4
7= (4)(0)+b
now solve for b
7 = 0 +b
7= b
so the equation of the line would be without the x and y points
y = 4x + 7
