Calculate and interpret the residual for the high school senior with foot length of 20 cm and a height of 160 cm

The vertical distance between a senior student with a height of 160 cm and his estimated height of 157.06 cm is 2.94 cm

Step-by-step explanation:

Given data,

TermCo eff      

Constant   105.08

Foot length2.599

Solving the problem for the given data

Frame the equation,

X= constant+ foot length ( foot length of 20 cm)

X=105.08+2.55(a)

Where  X denotes the predicated height

a denotes the foot length 20 cm

X=105.08+2.55(20)

X=157.06

The residual computed is given as

Z denotes the residual component

Z=Y-X

Z=160-157.06

Z=2.94 cm

Interpretation:

The vertical distance between a senior student with a height of 160 cm and his estimated height of 157.06 cm is 2.94 cm

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

t hope this
