Can you help me I will give you a branlist

[See Below]

Step-by-step explanation:

✦ Ok so first you need to turn the fraction into a decimal.

  ✧ 3/2 = 1.5

✦ You also must know the original points:

  ✧ D = (2, 6)

  ✧ E = (4, 2)

  ✧ F = (6, 4)

✦ Now here's the new points:

  ✧ D = (3, 9)

  ✧ E = (6, 3)

  ✧ F = (9, 6)

✦ Now I used a dilatation calculator to do this. So here's the image.

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.
