The answer is 13.25
67+92= 159
159 divided by 12= 13.25
8 and -8 cuz theyre both 8 in absolute form
Let x be the length of the edge of the original cube. When increased to twice its original size it becomes 2 x which gives a volume of
2x × 2x × 2x = 8x³
The volume is known. Hence
8x³ = 64,000
x³ = 8,000 which gives x = 20
<span>The area of one face of the original (before the increase) is given by x2</span>
x² = 20² = 400 square centimeters
Answer:
Two sample t procedure
Step-by-step explanation:
The reason for using the two sample t procedure is that it is mention in the statement that the firm takes a random sample of married couples and measure their annual salary and standard deviations are unknown and they are estimated by using the collected sample of data. Also there are two population in the data. Population one is the annual salary of husband and population two is the annual salary of wife and these are compared using two sample t procedure.
Answer:
(8,10)
Step-by-step explanation:
If we reflect a point over the y-axis, the x becomes opposite while the y stays the same.
So the rule here is (a,b)->(-a,b) if we are reflecting over y-axis.
So if you reflect (-8,10) over the y-axis you get (8,10).
