Assume this is f(x)=57.8(1.02)ˣ. This is a 2% increase each year.
When f(x)=200, 57.8(1.02)ˣ=200, (1.02)ˣ=200/57.8
Taking logs, xlog(1.02)=log(200/57.8), x= log(200/57.8)/log(1.02)=62.685.
Add 1960 to 62.685=2023 approx.

Answer:
r = -0.9997
Step-by-step explanation:
A statistics calculator gives the value
r = -0.9997
You can see in the graph below that it represents an excellent negative correlation between x and y.
Every point appears to be exactly on the regression line
.
Answer:
1.5
Step-by-step explanation:
You take 3% of 50.
<span>y = -2x + 19
y = x + 7
-2x + 19 = x + 7
x + 2x = 19 - 7
3x = 12
x = 4
</span>y = x + 7
y = 4 + 7
<span>y = 11
answer
</span><span>x = 4, y = 11</span><span>
</span>
