formula for the slope of a line, problem solving by solving simpler parts first, and cartesian plane for graphing.
Answer:
No, because the correlation coefficient is closer to 0 than to 1, which indicates a weak association between the variables.
Step-by-step explanation:
I got it correct
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
Answer:
Step-by-step explanation:
Given

Reflect over
This means that we reflect over the x-axis
And the rule of reflection is:
Hence:
Will become:
So, we have:
You can clear the zeros in the equation from the exponents. after you factor it should be
