Answer: 0.2551
Step-by-step explanation:
Given : The temperature reading from a thermocouple placed in a constant-temperature medium is normally distributed with mean μ, the actual temperature of the medium, and standard deviation σ.
Significance level : 
The critical z-value for 95% confidence : 
(1)
Since , 
(where x be any random variable that represents the temperature reading from a thermocouple.)
Then, from (1)
(2)
Also, all readings are within 0.5° of μ,
i.e. 
i.e. 
[From (2)]
i.e. 
i.e. 
The required standard deviation : 
Answer:
For which list does the total number have meaning? (What to see at the zoo)
For the list of facts it (does not) make sense to add the cost of a past, the area and the employees because these quantities (cannot) be expressed using the same unit. The number of 168 (does not) have meaning for the list
Step-by-step explanation:
Area is usually described in square feet while a population has no unit and a price is described in dollars therefore the list of facts has no meaning ( i got this question correct)
Answer:Step-by-step explanation:
so if you buy 2 jumpers it will be the cost of 1
and 30% of 50 is 15 so 15 + 15 = 30 plus 45 =
75
if the number of times spun is not a multiple of 8, it is impossible to land on an exactly even distribution for this spinner. But since the probabilities of landing on an exactly even distribution are so small, that detail doesn't perturb the overall trend, except perhaps down at n=8 spins So group 3
Question is Incomplete. Complete question is given below;
Maggie brought $10 to the candy store. She will buy a certain amount of fudge. One pound of fudge costs $2.30. If p represents the amount of fudge, in pounds, Maggie buys, which expression represents the money Maggie has left after visiting the candy store?
Answer:
The expression that represent the money Maggie has left after visiting the candy store is 
Step-by-step explanation:
Given:
Money Maggie brought at store = $10
Cost of 1 pound of fudge = $2.30
Let the amount of fudge be p
We need to find the amount of Money Maggie has left with after visiting the store.
The amount of Money Maggie has left with can be calculate by subtracting the amount of fudge she bought multiplied by Cost of 1 pound of fudge with Money Maggie brought at store.
The equation can be framed as;
Money left = 
Hence, The expression that represent the money Maggie has left after visiting the candy store is
