Answer:
The two readings that are cutoff values are T=1.84 deg C and T=-1.84 deg C.
Step-by-step explanation:
Thermometers rejected by measurements above normal represent 3.3% of the total, which indicates, by normal probability distribution data, that accepted thermometers are 96.7% likely to measure less than the maximum allowable temperature.
This value (P(X>x)=0.967) corresponds to z = 1.8388. Since the mean and standard deviation values are the same as the standard normal probability distribution (mean = 0, sd = 0), the z value is equivalent to the measured value (temperature).
Given the symmetry of the probability distribution, we can affirm that the thermometers rejected by measurements below the permissible measured a temperature lower than -1.8388.

The recursive formula is 
= 14; 
= 
+ 3
The explicit formula is 
Step-by-step explanation:
The recursive formula of the nth term of the arithmetic sequence is
= first term; = + d, where
- is the first term in the sequence
- is the nth term in the sequence
- is the term before the nth term
- n is the term number
- d is the common difference.
The explicit formula of the nth term of the arithmetic sequence is
, where
- is the nth term in the sequence
- a is the first term
- n is the term number
- d is the common difference
∵ The arithmetic sequence is 14, 17, 20, 23, 26
∴ The first term is 14
∵ 17 - 14 = 3
∴ The common difference is 3
∵ The recursive formula is = first term; = + d
∵ = 14
∵ d = 3
∴ = 14; = + 3
The recursive formula is = 14; = + 3
∵ The explicit formula is
∵ a = 14
∵ d = 3
∴ 
- Simplify the right hand side
∴ 
- Add like terms
∴
The explicit formula is
