Answer:
5.48% of the people in line waited for more than 28 minutes
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean and standard deviation , the z-score of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean waiting time of 20 minutes with a standard deviation of 5 minutes.
This means that
What percentage of the people in line waited for more than 28 minutes?
The proportion is 1 subtracted by the p-value of Z when X = 28. So
has a p-value of 0.9452.
1 - 0.9452 = 0.0548.
As a percentage:
0.0548*100% = 5.48%
5.48% of the people in line waited for more than 28 minutes
Hello lovely! The answer to your question is -8
Hope this helps!!!
It is a Binomial with a degree of 2? I couldn't fully understand the question.
Answer:
<em>mBAD = 244°</em>
Step-by-step explanation:
<em>~ Let us calculate the two unknown angles, represented by two lines each. These two lines are shared by each angle such that they are congruent ~</em>
m∠ APE = x = m∠ EPD,
360 - 136 = m∠ APE + m∠ EPD + 42 + 74,
224 = x + x + 42 + 74,
224 = 2x + 116,
2x = 108,
x = 54 = m∠ APE = m∠ EPD
Now that we know the measure of these unknown angles, let us solve for the degree measure of arc BAD, as such:
mBAD = m∠ BPA + m∠ APE + m∠ EPD,
mBAD = 136 + 54 + 54,
<em>mBAD = 244°</em>
Answer:25x+10x=$2.25
25=quarters and 10=dimes x is what we will plug in (how many coins Michael has for each type of coin) and $2.25 is how much money he has all together
Step-by-step explanation:
i used a money calculator and this is what it came too.
