Please help <br> The diagram shows a 5ft student standing near a tree
Novosadov [1.4K]

Answer:

25 ft

Step-by-step explanation:

The diagram shows two triangles that are similar.  Similar triangles have equal angles and sides that are proportional to each other.  Since the base of each triangle is given, we can find the proportion of the sides:

\frac{smaller}{larger}=\frac{8}{40}=\frac{1}{5}

Given the ratio of the smaller to larger triangle, we can set up a proportion to find the missing height of the larger triangle:

\frac{1}{5}=\frac{5}{x}, where 'x' represent the height of the tree

cross-multiply:  x = (5)(5) or 25 ft

It is estimated that approximately 10.5% of Americans are afflicted with diabetes. Suppose that a new diagnostic test is being c
Alla [95]

Answer:

0.03

Step-by-step explanation:

Percentage of americans with diabetes = 10.5% = 0.105

Percentage of americans without diabetes = 89.5% = 0.895

Adults over 40 with diabetes tested positive = 95% = 0.95

Adults over 40 with diabetes tested negative = 5% = 0.05

Adults over 40 without diabetes tested positive = 3.5% = 0.035

Adults over 40 without diabetes tested negative = 96.5% = 0.965

The probability of selecting an adult over 40 without diabetes but positive diagnosis;

     = 0.895 * 0.035

     = 0.031325

     = 0.03
