Answer:
x2-x1/y2-y1=2-4/10--2=2-4/10+2=-2/12
=-6
change 20 in to ft
20/12 = 1 2/3 ft
4 ft x ft
------- = ---------------
5 /3 ft shadow 120 ft
using cross products
4 * 120 = 5/3 x
480 = 5/3 x
multiply each side by 3/5
480 * 3/5 = x
288 ft
Answer: 0.0062
Step-by-step explanation:
Given : Mean : 
Standard deviation :
Sample size : 
Assume that age of people in the country is normally distributed.
The formula to calculate the z-score :-
For x = 32
The p-value = 
Hence, the the probability that the average age of our sample is at least =0.0062

use the multiplication property, it doesn't matter what wa ugh you do it because multiplication is on both sides
Answer:
S = √A
Step-by-step explanation:
Given that;
A = S²
Finding S implies making S the subject of the expression.
To do this;
A = S²
Take the square root of both sides of the expression;
√A = √S²
The square-root of the square of S = S;
S = √A
