Add up the 84 and 42 to get 126, then divide by 6 to get the number of tables which is 21. And the number of seats is 126 because you would need a seat for every person. Hope this helps.
Answer:
c. {545, 1045, 1545, 2045, 2545}
Step-by-step explanation:
Domain of a function is a set consisting of all the possible outcomes of the variable.
f(x)=500 x+45 where x= 1,2,3,4,5
the possible outcomes for this function are:
f(1)=500(1)+45= 545
f(2)=500(2)+45= 1045
f(3)=500(3)+45= 1545
f(4)=500(4)+45= 2045
f(5)=500(5)+45= 2545
Answer:
16.8
Step-by-step explanation:
equation: x - 3.9 = 12.9
add 3.9 to 12.9
answer is 16.8
Answer:
13.59% probability that my commute time tomorrow will take between 30 and 35 minutes
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean and standard deviation , the zscore 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 pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What is the probability that my commute time tomorrow will take between 30 and 35 minutes?
This is the pvalue of Z when X = 35 subtracted by the pvalue of Z when X = 30. So
X = 35
has a pvalue of 0.9772
X = 30
has a pvalue of 0.8413
0.9772 - 0.8413 = 0.1359
13.59% probability that my commute time tomorrow will take between 30 and 35 minutes
