Answer:
Step-by-step explanation:
-Given the population mean is and the standard deviation is , we calculate the z-scores using the formula:
#The z-score for 1910 can be calculated as:
#The z-score for 1230can be calculated as:
#The z-score for 2190 is calculated as follows:
#The z-score for 1380 is calculated as:
Answer:
B.
Step-by-step explanation:
Since the solution set is all real numbers, our solution graph must cover the entire number line.
We can see that B contains the graph that extends infinitely in both directions, thereby covering the entire number line.
Therefore, our answer is B.
A is not correct because it leaves out [-6, 1] (approximately).
C is not correct because it leaves out everything to the left of -7 and everything to the right of 1.
5/x = -9
5 = -9x (we have multiplied x out from the denominator)
5/-9 = x (divided by -9 to isolate x)
Answer:
225 ft^2
please give branliest if you do so please
Step-by-step explanation:
(12*10)+(5*5)+(8*10)
120+25+50
225
The answer would be 208 if you find the area of each quadrilateral and add them together.
