Answer:
Step-by-step explanation:
(27)^(-1/3) + (32)^(-2/5)
1/3 + 1/4
4/12 + 3/12 = 7/12
at first we write each one as a sequence
and find its equation
the first table
-19, -11, -3, 5
8x-19
the third table
15,12,9,6
-3x+15
the second table
-1. 5,1.5,3,4.5
+3 +1.5 +1.5
so the third table is the nonlinear function
Answer:
The probability that the diameter falls in the interval from 2499 psi to 2510 psi is 0.00798.
Step-by-step explanation:
Let's define the random variable, 
"Comprehensive strength of concrete". We have information that 
is normally distributed with a mean of 2500 psi and a standard deviation of 50 psi (or a variance of 2500 psi). In other words, 
.
We want to know the probability of the mean of X or 
that falls in the interval ![[2499;2510]](https://tex.z-dn.net/?f=%5B2499%3B2510%5D)
. From inference theory we know that :
Now we can find the probability as follows:
Where 
, then:
