(3p + 1) + 6(p – 8) – (p + 2)

Distribute the Negative Sign:

=3p+1+6(p−8)+−1(p+2)

=3p+1+6(p−8)+−1p+(−1)(2)

=3p+1+6(p−8)+−p+−2

Distribute:

=3p+1+(6)(p)+(6)(−8)+−p+−2

=3p+1+6p+−48+−p+−2

Combine Like Terms:

=3p+1+6p+−48+−p+−2

=(3p+6p+−p)+(1+−48+−2)

=8p + −49

what are the statements? and what do you mean by "216 2 1 6"?

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.
