20 POINTPLEASE HELPP The scores on a certain standardized test follow a normal distribution. The mean score is 76, and the standard deviation is 9. Find the percentage of test scores that are greater than 90. Round to the nearest percent and type your numerical answer below.

I’m a smart person so that’s why i think it was 6

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
