Answer:

C. x ≈ 0.28

Step-by-step explanation:

A graphing calculator solution is attached. It shows ...

x ≈ 0.28

You can divide both sides of the given equation by 5, then take natural logs and divide by 5 again.

5e^(5x) = 20 . . . . . . given

e^(5x) = 4 . . . . . . . . divide by 5

5x = ln(4) . . . . . . . . take natural logs

x = ln(4)/5 . . . . . . . divide by 5

x ≈ 0.277259 ≈ 0.28

I need help! What is the value of t?

Nezavi [6.7K]

The t-value measures the size of the difference relative to the variation in your sample data. Put another way, T is simply the calculated difference represented in units of standard error. The greater the magnitude of T, the greater the evidence against the null hypothesis.
