Question

Solve the equation. 2ª = 0.36 O + or - 0.5 O+ or - + or - 0.6 + or -0.7 06 please answer quickly ​

Answer 1

2nd answer is correct.

Explanation:

z² = 0.36

z² =
`(36)/(100)`

z² =
`(6 * 6)/( 10 *10)`

z = ± √ (
`(6 * 6)/( 10 *10)` )

z = ±
`(6)/(10)`

z = ± 0.6

Therefore,

z = + or - 0.6
