Help!! Question 2/7 points) Find that quadrilateral ABCD with vertices A(0, 0), B(6,0), C(5,2), and D(1, 2) is an isosceles trapezoid by showing that its diagonals are congruent. Write SLOPES as reduced improper fractions or whole numbers (NO DECIMALS) Slope of AB = 0 Slope of BC = -2 Slope of CD = 0 Slope of DA = 2 Length of AC = (round to the nearest tenth) Length of BD = (round to the nearest tenth) Are the diagonals congruent? yes (yes/no)

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.
