The magnitude of a star is a number that is a measure of its brightness
as seen on Earth. The brighter the
star, the lower its magnitude. The
data below show the magnitudes of
five stars in our galaxy. Between
what two integers is the magnitude
of each star located? In most
applications, the magnitude of a
number is its size or amount.
However, when talking about the
magnitude of a star, magnitude
includes negative numbers.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

-10x = -5

x = 0.5

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.
