Answer:
The probability of getting a reading between -1.42 degree C and 1.61 degree C is 0.8685.
Step-by-step explanation:
We are given that
degree C
Standard deviation, 
degree C
We have to find the probability of the reading between -1.42 and 1.61.
Using the formula
Hence, the probability of getting a reading between -1.42 degree C and 1.61 degree C is 0.8685.

(7,-3) and (4,0)
Answer:
= 
Step-by-step explanation:
When dividing values with exponents, we simply need to subtract the numerators exponent to the denominators exponent.
So we have:
= 
= 
Now since we have a negative exponent, we can get the reciprocal of the value to make it positive.
=
