Hiking The scatter plot shows a hiker's elevation above sea level during a hike
from the base to the top of a mountain. The equation of a trend line for the
hiker's elevation is y = 7.81x + 672, where x represents the number of minutes
and y represents the hiker's elevation in feet. Use the equation of the trend line
to estimate the hiker's elevation after 155 minutes.
Please help I’m so tired

Step-by-step explanation:
Given:
Geraldo current age = 25years.
Policy being considered for = 30years
Age at the end of the policy = 55years
What is the probability that Geraldo lives to be 55years.
Therefore
P ( A + B ) = 25 /55 + 30 / 55
= 5 / 11 + 6 / 11
= 11 / 11
= 1
