Answer: 0.9938
Step-by-step explanation:
Let x be the random variable that represents the daily revenue at a university snack bar.
As per given , we have
,
and n= 100
Using formula
,
z-score for x= 2600

The probability that the average daily revenue of the sample is higher than $2600 :
[P(Z>-z)=P(Z<z)]

Therefore, the probability that the average daily revenue of the sample is higher than $2600 = 0.9938
Answer:
We know that lines <em>l</em><em> </em>and <em>m</em><em> </em>are parallel. The alternate interior angles rule states that the alternate interior angles formed by parallel lines are equal. So let's equate them.
2x + 22 = 4x
putting variables on one side,
22 = 4x - 2x
Thus 2x = 22
x becomes 22÷2
Therefore,<u> x = 11.</u>
