Given that variance of a data set is:
Variance=σ²
the standard deviation is the square root of the variance:
thus
standard deviation= √(variance)
variance,σ²=104.04
thus
std deviation=√σ²=√104.04
thus
σ=10.2
The area of the triangle with a base of 10in and height of 5in is 25 square inches
<h3>How to find the area of a triangle</h3>
A triangle is a to dimensional shape with 3 sides and angles
Area of a triangle = 0.5bh
<h3>
Given the following parameters</h3>
base = 10in
height = 5 in
<h3>Substitute the given parameters into the formula</h3>
A = 0.5 * 10 * 5
A = 25 square inches
Hence the area of the triangle with a base of 10in and height of 5in is 25 square inches

Answer: 860
Step-by-step explanation:
there isn't a 860 for an answer but it's the correct answer.
7 inches → 280 yards
1 inch → 280 ÷ 7 = 40 yards
5 inches → 40 x 5 = 200 yards
Area = 280 x 200 = 56 000 yards
Answer: 56 000 yards
