The diagram shows a triangle. work out the area of the triangle.

30cm^2

Step-by-step explanation:

area of triangle = bxh/2

12x5=60/2=30cm^2

My answer is 30.

Step-by-step explanation:

Area of a triangle is 1/2×b×h or b×h/2.

The base in the diagram is 12 and the height is 5. then 12×5=60 then 60÷2=30Thank you for the question

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.
