What is √432+√650 in simplified radical form?

Step-by-step explanation:

Simplify the following:

4 sqrt(32) + 6 sqrt(50)

sqrt(32) = sqrt(2^5) = 2^2 sqrt(2):

4×2^2 sqrt(2) + 6 sqrt(50)

2^2 = 4:

4×4 sqrt(2) + 6 sqrt(50)

sqrt(50) = sqrt(2×5^2) = 5 sqrt(2):

4×4 sqrt(2) + 6×5 sqrt(2)

4×4 = 16:

16 sqrt(2) + 6×5 sqrt(2)

6×5 = 30:

16 sqrt(2) + 30 sqrt(2)

16 sqrt(2) + 30 sqrt(2) = 46 sqrt(2):

46 sqrt(2)

Simplify the following:

4 sqrt(32) + 6 sqrt(50)

sqrt(32) = sqrt(2^5) = 2^2 sqrt(2):

4×2^2 sqrt(2) + 6 sqrt(50)

2^2 = 4:

4×4 sqrt(2) + 6 sqrt(50)

sqrt(50) = sqrt(2×5^2) = 5 sqrt(2):

4×4 sqrt(2) + 6×5 sqrt(2)

4×4 = 16:

16 sqrt(2) + 6×5 sqrt(2)

6×5 = 30:

16 sqrt(2) + 30 sqrt(2)

16 sqrt(2) + 30 sqrt(2) = 46 sqrt(2):

46 sqrt(2)

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.
