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

Answer:

2nd answer is correct.

Step-by-step explanation:

z² = 0.36

z² = $\frac{36}{100}$

z² = $\frac{6 * 6}{ 10 *10}$

z = ± √ ( $\frac{6 * 6}{ 10 *10}$ )

z  = ± $\frac{6}{10}$

z = ± 0.6

Therefore,

z = + or - 0.6
