The swimming team has competed in 45 races this season. they have won 30 races so far. how many races will the team need to win today for the team to have a 75% success rate?
pls soon, will mark brainliest

15 races

Step-by-step explanation:

The team has competed in 45 and has won 30. So the success rate is:

Success rate is:

We have to find the number of races the team needs to win for 75% success rate

Which means that

We have to solve the equation for x

The team needs to win 15 races to get 75% success rate ..

step-by-step explanation:

do you have a copy of the table?

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
