The illustration below shows that the pressure p that divers experience is related to the depth d of the dive. A linear model can be used to describe this relationship.

(a) Write the linear model in slope-intercept form.

p =

(b) Scuba divers can safely dive to depths of 245 feet. What pressure do they experience? Round to the nearest tenth.

p =

psi

Sea level (d = 0)

Pressure = 14.7 pounds

per square inch (psi)

d = 33

Pressure = 29.4 psi

d=66 ft

Pressure = 44.1 psi

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.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
