Match the following. Given
D = {x I x is a whole number)
E=[xl x is a perfect square < 100)
F={x 1 x is an even number between 10 and 20)
1. DNE
(all whole numbers)
2. DNF
(16)
[1, 4, 9, 16, 25, 36, 49, 64, 81, 12, 14,
3. Dn (EN)
18)
(12, 14, 16, 18)
4. DUENF)
5. DN (EUF)
(1, 4, 9, 16, 25, 36, 49, 64, 81)

they are simplified

step-by-step explanation:

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.
