<span>Given are the following data:
Heart failure causes:
84% natural occurence
16% outside factors
18 individuals (sample size)
1. What is the probability that 3 individuals have conditions caused by outside factors?
Probability = 3/18 * 0.16 = 0.0267 or 2.67%

Answer:
the areas of these triangles are 83.2cm² and 46.8cm²
Step-by-step explanation:
1. If the triangles are similar and the ratio of the perimeter ois 4:3, then the areas are in the following ratio:
4²:3²
16:9
2. The sum of their areas is 65 cm², then, you can calculate the area of the larger triangle as following:
130(16/16+9)
130(0.64)
=83.2cm²
3. The area of the smaller triangle is:
130(9/16+9)
130(0.36)
46.8cm²

Answer:
She needs to purchase 50 square feet of wood .
Step-by-step explanation:
we can find the number of square feet of wood needed to purchase by finding the area of the table
The area of the table = area of the triangle + area of the rectangle
Area of the triangle:
Area of the triangle =
On substituting the values from the attached figure , we get
Area of the triangle =
Area of the triangle =
Area of the triangle = 10 square feet
Area of the rectangle:
Area of the rectangle = Length X Breadth
On substituting the values from the attached figure , we get
Area of the triangle =
Area of the triangle = 40 square feet
Thus the area of the table = 10 + 40 = 50 square feet
