Answer:
Step-by-step explanation:
Do you mean 3/7x or 3/(7x) ?
If 3/7x = 33 then x = 33·7/3 = 77
If 3/(7x) = 33 then x = 1/77
Answer:
The population mean
Step-by-step explanation:
Sample Mean is the mean of of the selected samples while the population Mean is the mean of all the population. The mean of the sampling distribution of the sample mean is equal to the mean of the original distribution (that is the sample mean is equal to the population mean).
The mean of the sample means is always approximately the same as the population mean
The total sum is 180 because 3 angles = 180
54 + 11s + 7s = 180
-54. -54
18s = 126
S = 7
Answer:
The equation is x= (7.74 /9) 6
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
If 9 pencils cost $7.74, we have to divide the total cost ($7.74) by the number of pencils (9) to obtain the price of 1 pencil.
Now that we have the price of 1 pencil, to obtain the cost of 6 of them we simply multiply the result by six.
Mathematically speaking:
x= (7.74 /9) 6
Where:
x = Cost of 6 pencils in $
Solving:
x = 0.86 x 6 = $5.16
