If a denotes some​ event, what does upper a overbara ​denote? if ​p(a)equals=0.9930.993​, what is the value of ​p(upper a overba
masya89 [10]
P(A) = 0.993 is the probability of event A
    _
P(A) is the probability of not A (note that I am trying to place a bar over A. I hope you can see it, else it is because the editor did not show it as I intended)

Then, use the fact that the probability of A plus the probability not A is equal to 1:
                    _
=> P(A) + P(A) = 1
         _
=> P(A) = 1 - P(A) = 1 - 0.993 = 0.007

So, the answers are:
        _
1) P(A) = 0.07
             _
2) Yes, A is unlikely because its probability is very low.

Marie uses 2.3 oz of nuts for each bag of trail mix she makes. She uses 27.6 oz of nuts in all. How many bags of trail mix does
anastassius [24]
We are given that each bag of trail mix consumes 2.3 oz of nuts. To know the amount of bags of trail mixes that can be made using 27.6 oz of nuts, all we have to do is cross multiplication as follows:
2.3 oz of nuts ............> 1 bag of trail mix
27.6 oz of nuts ...........> ?? bag of trail mix

number of bags = (27.6*1) / 2.3 = 12 bags

A standardized test has a mean of 110 points and a standard deviation of 10 points. John scored at the 98th percentile on the te
Mariana [72]

Answer: his score 131 points

Step-by-step explanation:

Assuming the scores in the standardized test are normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = standardized test scores.

µ = mean score

σ = standard deviation

From the information given,

µ = 110 points

σ = 10 points

Looking at the normal distribution table, the z score that corresponds to the 98 percentile is 2.06

2.06 = (x - 110)/10

Cross multiplying, it becomes

2.06 × 10 = x - 110

2.06 = x - 110

x = 20.6 + 110

x = 130.6

Approximately, x = 131
