Bivin is the fitness director at Lake Air Fitness Center. He recommends that the intensity of aerobic activities be measured by pulse rate. Following generally accepted practice, he recommends that the clients achieve a pulse rate depending on their age and level of activity. The target pulse rate is determined as follows: Subtract the person's age from 220 to obtain a "maximum pulse rate." Those beginning aerobic activities should exercise at a level so that their pulse rate (per minute) is 40% of their maximum rate. For burning calories, the person should exercise at a level that achieves 60% of his or her maximum rate. Write the equations that give the relationship between a person's age and desired pulse rate for the following. (Use x for person's age and p for pulse rate.)
(a) the beginner

(b) the person desiring to burn calories

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.

costs the what? what is the cost of the pants?

step-by-step explanation:

if it is $10, then the price is 14.

take 40% of the cost, and then add the cost.

40% of 10 = 4

4+10 = 14.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
