First, subtract 13.24 from both sides of the equation and add -3.1t on both sides of the equation. This isolates the variable t:
-15.5t + 3.1t = -13.44 + 10.56 - 13.24
Now combine the numbers on both sides of the equation and solve for t:
-12.4t = -16. 12
t = 1.3
Hope this helps!
Here where you label the y and slope
Let x be a random variable representing the mean number of flaws per square yard inspected
P(x > 1.8) = P(z > (1.8 - 1.7)/0.8) = P(z > 0.125) = P(z < 0.125) = 0.5497
First one = 9x3=27
Second one 12x9=108
3rd one = 3x4=12
Idk what that last one is
