What is the area of the triangle given below

c. 35 sq. units

how you get that is you multiply

5 x 14 = 70

then divide by 2

70 divided by 2 = 35

formula

base x height divided by 2 = area of triangle     (remember to square it also)

24+x=y

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.
