Answer:
1303.45 cm
Step-by-step explanation:
The triangles formed by a rod and its shadow and a tree and its shadow are similar triangles, so the ratios of their heights to the lengths of their shadows are equal.
Let x be the height of the tree. Setting the ratios equal, we get:
180/116 = x/840
Solve for x:
x = 840 * (180/116)
x ≈ 1303.45 cm
Answer:
Step-by-step explanation:
Hello!
The variable of interest is X: number of criminals in the 10 Most Wanted list that were captured in a sample of 523 suspected criminals.
The number of criminals that were captured is 172 out of 523.
To calculate the sample proportion, you have to divide the number of success, in this case, captured criminals, by the total number of criminals sampled:
^p= 172/523= 0.329
I hope this helps!
