Answer:
<h2>(a) 5,050 psi.</h2><h2>(b) 5,051.3 psi.</h2><h2>(c) 5,180 psi.</h2><h2>(d) 4,920 psi.</h2>
Step-by-step explanation:
The given function is
Where 
represents the accelerated strength in psi, and 
represents 28-day standard-cured strength in psi.
Part a is about finding the y-value for 
Therefore, the expected value of 28-day strength when accelerated strength is 2,500, is 5,050 psi.
Part b is about the y-value for 
Part c is about the y-value for 
Part d is about the y-value for 
Answer:
the answer is the choice C. because
27/9 equals 3 . the answer is 3 .
Assuming you know the mean (mu) and the standard deviation (sigma), you would use the raw score (x) to get the z score through this formula
z = (x-mu)/sigma
If you get a positive z value, then the raw score is above the mean. If z is negative, then the raw score is below the mean.
The absolute value of z tells us how far away from the mean we are in terms of standard deviation.
Eg: z = -3 leads to |z| = |-3| = 3, so we're 3 standard deviations below the mean.
Answer:
Step-by-step explanation:
Two different people are mentioned??
If this is for the same person:
-20 -20-10 = $-50.00
She's already in the negative $10, minus the check of $20 and the fee of $10
