<u>Best Fit Regression Model</u>
Scientists often wonder if there is a relationship between the variables under study. It's a vital matter in modern times where artificial intelligence technology is struggling to find answers where traditional approaches hadn't before.
The most-used tool to find relations between variables is the regression model and its best fit lines to try to find an expression who relates variable x (years from 1960) and variable y (minimum wage requirement) as of our case.
The data was entered into a digital spreadsheet and an automatic function was applied to find the best-fit model.
The automated tool's output was this equation:
That can be rounded to three decimals
We select the option c.
Answer:
16 faults
Step-by-step explanation:
<u><em>The correct question is</em></u>
In tennis, a first serve can be an ace, a fault, or it can be returned. In one match, a tennis player hit 24 aces, which was 2/5 of all her first serves. If 1/3 of her first serves were returned, how many of the tennis player's first serves were faults?
Let
x -----> the number of all her first servers
y ----> the number of first services returned
z ---> the number of first services faults
we know that
The number of aces plus the number of returned plus the number of faults must be equal to the number of all her first services
so
step 1
Find out the number of all her first servers
we have that
Solve for x
step 2
Find out the number of first services returned
substitute the value of x
step 3
Find out the number of first services faults
we have
substitute and solve for z
