Question

Use the equation ˆ y = 16.279 − 0.206 x to find the value of ˆ y given x = 48 . Round the result to the nearest tenth.

Answer 1

`y=6.391`

Explanation:

Given

`y=16.279 - 0.206x`

Required

Find y when
`x = 48`

Substitute
`48` for
`x` in
`y=16.279 - 0.206x`

`y=16.279 - 0.206 * 48`

Multiply

`y=16.279 - 9.888`

Subtract

`y=6.391`
