I’m sorry what? Explain ?
From the problem statement, the population of South Africa is four times the population of Greece.
The population of Greece is 11 million
<em>Given data</em>
Population of South Africa is 44 million,
Let the population of Greece be x
Hence the population of South Africa will be = 4*x
Hence the expression becomes
44million = 4x
Let us divide both side by 4 to find the population of Greece
x= 44million/4
x = 11 million
Hence the population of Greece is 11 million

Answer:
His actual score is 15
Step-by-step explanation:
Here, we are interested in calculating Wayne’s actual score on the ACT
when we say the scores have being standardized, it means the score was reported in terms of the z-score and not the initial raw scores.
Now, mathematically, for the scores to have a negative z-score, it means it is actually below the mean.
The formula for the z-score or standard score is given below;
z-score = (x - mean)/SD
where in this case, x = ? which is the score we are looking for , z-score = -0.5 , mean score = 18 and standard deviation of the scores = 6
So, substituting these values into the z-score equation, we have;
-0.5 = (x-18)/6
x-18 = 6(-0.5)
x -18 = -3
x = -3 + 18
x = 15
Answer:
A is one of the true statements because 25 is the largest number that 50 and 75 can both divide evenly into.
D is the other true statement because 45 is the lowest number that 5 and 9 can both multiply into.
