Answer:
R (1 1/3 , 3) or (1.333 , 3)
Step-by-step explanation:
R (x,y)
x = 3 - (3 - (-2))/3 = 3 - (5/3) = 3 - 1 2/3 = 1 1/3
y = 2 + (5-2)/3 = 2 + 1 = 3
R (1 1/3 , 3) or (1.333 , 3)
I believe its 15 girls.
If its 5 girls to every 4 boys and there is 12 boys then 12 is just 4 three times so you would do 5 three times making it 15.
4boys = 5girls
+4boys= 5girls
+4boys = 5girls
=12boys = 15girls
A) the perimeter of a triangle is the bottom plus the left slanty side plus the right slanty side, but you need the bottom in ft so that would be 6 ft. the perimeter is 13 ft
b) 1 yard
Explanation:
The sample mean is not always equal to the population mean but if we take more and more number of samples from the population then the mean of the sample would become equal to the population mean.
The Central Limit Theorem states that we can have a normal distribution of sample means even if the original population doesn't follow normal distribution, But we have to take a lot of samples.
Suppose a population doesn't follow normal distribution and is very skewed then we can still have sampling distribution that is completely normal if we take a lot of samples.
