Mean = sum of values / number of values
74 = x/32
2368 = x

70 = y/19
1330 = y

mean for female students = (2368 - 1330)/(32-19) = 79.85

Answer:

The second beach has a higher chance of being dry.

Step-by-step explanation:

At the first beach, it rained 5 out of 30 days. 5 over 30 is 1/6. 10% which is the second beach's rain rate is equivalent to 1/10. since 1/6 is greater than 1/10, the second beach will have a lower rain rate.

Brainliest answer and 5 points
Studentka2010 [4]
Answer: Choice C) Infinitely many solutions

If you solve the first equation for y, you get
2y = 14 - 2x
2y = 14 + (-2x)
2y = -2x + 14
2y/2 = (-2x)/2 + 14/2 ... divide every term by 2
y = -x + 7

This result of y = -x+7 is identical to the second equation in the system. So the two graphs are going to be the same. We only produce one line. One graph is right on top of the other. The two lines will intersect infinitely many times. Any point on the blue line is a solution to the system.
