The table shows the number of visitors y (in thousands of people) an amusement park has had each year over x years. Use a graphi ng calculator to find an equation of the line of best fit. Round the slope and y-intercept to the nearest hundredth. Then identify and interpret the correlation coefficient.
1 answer:
Answer:
The equation of the line of best fit is: y = -2.33x + 591.78
The correlation coefficient is: -0.99
There is a strong negative correlation
Step-by-step explanation:
The negative correlation is seen in the sign of the correlation coefficient, which is negative.
The correlation is strong because the absolute value of the correlation coefficient (0.99) is near to one

Answer:
All answers in this set can be written in the form y=f(x).
Answer:
Two equal sides = 14.4 inches each
Shortest side = 7.2 inches
Step-by-step explanation:
a + b + c = 36
a = b
a = 2c
then:
c = a/2
a + a + a/2 = 36
2a + a/2 = 36
4a/2 + a/2 = 36
5a/2 = 36
a = 2*36/5
a = 72/5
a = 14.4
a = 2c
14.4 = 2*c
c = 14.4/2
c = 7.2
a = b
b = 14.4
Check:
14.4 + 14.4 + 7.2 = 36
