<span>240 Acres
2/5 = .4
.4 times 600 = 240

To solve for p, square both sides and move the equation to one side is equal to zero. Then factor. I chose -2 and -5 because -2 x -5 = 10 and -2 + -5 = -7. After factoring, solve p-5=0 and p-2=0. When one of those equals zero then the equation (p-5)(p-2)=0 is true.
At this point in time, you can use a technique called cross-mutiplication, where you say that
, and
at this point in time, you can devide each side by 8 and solve
Concurrent validity is a type of evidence that can be gathered to defend the use of a test for predicting other outcomes. It is a parameter used in sociology, psychology, and other psychometric or behavioral sciences. Concurrent validity is demonstrated when a test correlates well with a measure that has previously been validated. The two measures may be for the same construct, but more often used for different, but presumably related, constructs.
Answer:
mean=sum of data/no of data
=12/3
=4
Step-by-step explanation:
therefore mean=4
