Solving for the elapsed time
distance traveled = (speed of first train + speed of second train) * elapsed time
280 miles = (95 mph + 105 mph) * elapsed time
280 miles = 200 mph * elapsed time
elapsed time = 280 miles / 200 mph
elapsed time = 1.4 hours
elapsed time = 1 hour and 24 minutes
It will take 1 hour and 24 minutes for the two trains to be 280 miles apart.
Answer:
it means replace x with 27
Step-by-step explanation:
![\sqrt[3]{27 + 98} + 5 = \sqrt[3]{125} + 5 = 5 + 5 = 10](https://tex.z-dn.net/?f=%20%5Csqrt%5B3%5D%7B27%20%2B%2098%7D%20%20%2B%205%20%3D%20%20%5Csqrt%5B3%5D%7B125%7D%20%20%2B%205%20%3D%205%20%2B%205%20%3D%2010)
The statement " only the estimate intercept is statistically significant at the 5% level is wrong" is wrong about the estimate.
<h3>What is probit regression?</h3>
A probit model is a type of regression in statistics where the dependant variable can only take two values.
We have:
Regress smoker on cubic polynomials of age
If we use linear probability model.
Here the data are missing, but we can say about the estimate that:
Only the estimate intercept is statistically significant at the 5% level is wrong,
Thus, the statement " only the estimate intercept is statistically significant at the 5% level is wrong" is wrong about the estimate.
