Express 9 times 81 times 27^3 times 3^5 as a single base and as an exponent

what the question

Step-by-step explanation:

Step-by-step explanation:

9 × 81 × 27³ × 3⁵ =   3² × 3⁴ ×  (3³)³ × 3⁵

                           = 3² × 3⁴ ×  3⁹ × 3⁵

                           = 3 ² ⁺ ⁴ ⁺ ⁹ ⁺ ⁵

                           = 3²⁰

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
