<span>Raul only hit 19 times out of 45 bats.
Now, let’s find the average decimal value of Raul’s hit.
=> 19 hits
=> 45 bats
x = value in decimals
=> 19 = x * 45
=> 19 = 45x
Now, divide both sides with 45
=> 19/45 = 45x / 45
=> 0.4222222 = x
x = 0.422222……..
Since it is a repeating decimals, and we only need to find the thousandths
value. Let’s get the value of Thousandths.
=> 4 = tenths
=> 2 = hundredths
=> 2 thousandths
Therefore the value of 19 hits out of 45 bats in decimals is
=> .422 </span>
First divide by 4 to get x^2=9. Then take the square root of both sides. x=3 and x = -3.
A 7/4 because the slope of the line is 7/4
70+75+80+90+100=415
415/5=83
