When accelerated strength increases by 1 psi, the expected change in 28-day strength is ₁ = 1.2. Therefore, when accelerated strength increases by 2 psi, the expected change in 28-day strength (in pounds per square inch) is 23₁ = Your answer cannot be understood or graded. More Information psi. We can follow this model to see that the expected change in 28-day strength is equal to ₁ = 1.2 times the increase in accelerated strength. Therefore, the expected change in 28-day strength (in pounds per square inch) for an increase of 80 psi in accelerated strength is equal to 1.2 80 Submit Skip (you cannot come back) ✔ or 96 ✔ psi

PLEASE answer the wrong ty.

Step 3 (c) By how much can we expect 28-day strength to change when accelerated strength increases by 80 psi? When accelerated strength increases by 1 psi, the expected change in 28-day strength is ₁ = 1.2. Therefore, when accelerated strength increases by 2 psi, the expected change in 28-day strength (in pounds per square inch) is 20₁ * Your answer cannot be understood or graded. More Information psi. = We can follow this model to see that the expected change in 28-day strength is equal to ₁ = 1.2 times the increase in accelerated strength. Therefore, the expected change in 28-day strength (in pounds per square inch) for an increase of 80 psi in accelerated strength is equal to 1.2 80 Submit Skip (you cannot come back) ) or or 96 psi.
