Lower limit for H is given as = 7/10*(220-a) where a is the age of the person
a. We have to calculate the lower limit for a person whose age is 47
We substitute the age "a" = 47 in the above equation to calculate the lower limit .
Lower limit = 7/10*(220-47)
Lower limit = 7/10*173
Lower Limit = 1211/10 = 121.10 = 121 beats/minute (since we cannot have fractional beats)
Lower limit of the heart range in beats per minute = 121 beats/minute
The median is the middel # so that means u will add 5 plus 8 and u get 13 and then u would divide by 2 bc there r two # and then the answer will be 6.5 i hope that the answer

Answer:
y = 2x -5
Step-by-step explanation:
The first point tells the y-intercept of the line, -5, the value of y when x=0.
The slope is ...
(change in y)/(change in x) = (3 -(-5))/(4 -0) = 8/4 = 2
The slope-intercept form of the equation of a line is ...
y = (slope)x + (y-intercept)
Filling in slope=2 and y-intercept = -5, the equation is ...
y = 2x -5
