Let x be the number of movies rented
Let y be the number of video games rented
(5x+2y=26)4
- 3x+8y=53
20x+8y=104
-3x+8y=53
-----------------
17x =51
x=51/17
x=3
5x+2y=26
5(3)+2y=26
2y=26-15
y=11/2
y=5.5
Therefore, the movies cost $3 and the video games cost $5.5
Hope I helped :)

The answer to your questions would be “46 degrees” :) you’re welcome
Answer:
The histogram of the sample incomes will follow the normal curve.
Step-by-step explanation:
According to the Central Limit Theorem if we have an unknown population with mean <em>μ</em> and standard deviation <em>σ</em> and appropriately huge random samples (<em>n</em> > 30) are selected from the population with replacement, then the distribution of the sample mean will be approximately normally distributed.
In this case the researches wants to determine the monthly gross incomes of drivers for a ride sharing company.
He selects a sample of <em>n</em> = 200 drivers and ask them their monthly salary.
As the sample selected is quite large, i.e. <em>n</em> = 200 > 30, the central limit theorem can be applied to approximate the sampling distribution of sample mean by the Normal distribution.
Thus, the histogram of the sample incomes will follow the normal curve.
