This would be easier to explain if I had a paper and a pen, but I will give it a try :=)
Try drawing a picture of the problem and look at it while you read my explanation, it might help :=)
In a cross, the opposite angles will always be the same size, therefore, the opposing angle of the given is 72 degrees. Then we can use the knowledge that one of the unknown and one of the 72 will together be 180 degrees. Therefore, the other angle will be 180-72 = 108 and its opposite will be the same.
So the measures for the other three angles are: 108, 108 and 72.
-1(x + 5) = -x - 5
-1(x - 5) = -x + 5
-(x + 3) = -x - 3
-(x - 3) = -x + 3
First, you have to add 16 to both sides because it's the opposite of subtracting.
h-16<24
+16 +16
-16+16 will cancel each other out.
24+16=40
So, h<40
Or in other words, h is smaller than 40.
Hope it helps ^_^
Answer:
23 pounds and 9 ounces (23lb 9 oz)
Step-by-step explanation:
You can add the pounds together and the ounces together separetly. As long as the ounces are less than 16 (since 16 ounces=1 pound), you wont hvae to convert those ounces into pounds. So you can simply add the numbers up to get 23 pounds and 9 ounces
Answer:
a) There is outlier (lower category), but this outlier seem certain to be due to an error.
b) There is outlier (upper category), this outlier seem certain to be conceivably correct.
Step-by-step explanation:
a) The outlier in the rock weight is certain to be due to an error. As shown, the rock was weighed five time to ascertain the actual weight or perhaps to known the mean weight. <em>Thus, having a value 4.91 can not be true. It can only be due to an error of recording the values.</em> It suppose to be recorded as 49.1.
b) Since this was a sample of annual income of five different families, it quite possible that a particular family annual income is $1, 200, 000. Hence, we cannot regard this outlier an error, rather conceivably true.
