ANSWER
0.2546
EXPLANATION
The movie theatre's daily revenue, X, is normally distributed with a mean of $3152 and a standard deviation of $1281.
We have to find the probability that the theatre generates more than $4000 in revenue on a randomly selected day,
To find this probability, we have to standardize X using the formula,
So the probability is,
Now, we have to look up this z-value in a z-score table. These tables usually show the area to the left of the z-score - this means that they show the probability for a z less than the z-score, so we have to find the complement,
In a z-score table,
So the probability is,
Hence, the probability that the theatre generates more than $4000 in revenue on a randomly selected day is 0.2546.
Answer:
The same slope and different y-intercepts.
Step-by-step explanation:
If the slope is different, they will collide.
If the y-intercept is the same, there will be infinite solutions.
Step-by-step explanation:
24 + 28
2*2*2*3 + 2*2*7 [prime factors]
You may distribute any common ones, for example:
4(6+7) [that is, 2*2*(2*3 + 7)
2(12+14)
I’m pretty sure it’s C. because half of 12 is 6 so if they’re buying a pound and a half it would be 12+6, which is 18
