Answer:
log (2/5)
Step-by-step explanation:
The rule/law you have in mind is as follows: log a - log b = log (a/b).
Thus, your log 2 - log 5 = log (2/5).
When quantities are in a proportional relationship, they are related to each other by a multiplicative constant. That is the case for selections F, G, J, but not the case for selection H.
You are asked to find the relationship that is NOT a proportional relationship. The appropriate choice is ...
H. y = 1/2 + x
Correlation coefficients are expressed by a number between -1 and 1.
If the value is -1 or 1 it indecates a perfect (negative and positive) correlation.
If the value is 0 indicates null correlation.
As the correlation value for you data set is -0.833 it is very close to the -1. It indicates a good correlation in the data. Then, the value you predicted is reasonably close to the actual value.
Answer:
x = 69
Step-by-step explanation:
Given
35 + x + 76 = 180, that is
x + 111 = 180 ( subtract 111 from both sides )
x = 69
