Answer:
Step-by-step explanation:
From the given exponential graph, the y-intercept is (0,10).
The only exponential function that, has this intercept is
Because when x=0, we obtain:
Simplify:
There is no solution to the equation.
The x is cancelled out.

Step-by-step explanation:
A 90% confidence interval is centered at a parameter and is 90% sure to contain the statistic.
When you are running a statistical test, you can create a confidence interval centered at the appropriate parameter (such as the mean) to see if the statistic stated in your null hypothesis is true if it's contained in the interval. Whatever the confidence level is determines how wide the interval will be, and as such, will determine how likely the interval will catch the statistic in question.
Answer:
287
Step-by-step explanation:
400+10=410
(70:100)*410
(70*410):100
28700:100 = 287
