Answer:
Two sample test of means with unknown variance (standard deviation) but assumed equal
Step-by-step explanation:
For the scenario described above, we apply the two sample test means with unknown variance (standard deviation) but assumed equal test because, the there are two differebt or independent groups, each with its owm subjects or observations. The population variance or standard deviation aren't given. However, the variance are assumed to be equal., since the two groups of sample are chosen from the same population. Therefore, for the scenario described above, the most appropriate test would be a Two sample test of means with unknown variance (standard deviation) but assumed to be equal
Answer:
it depends on the type of line but for a straight line the starting point is always the edge that is A
You add or subtract it for instance: 14x+258-52. You have to subtract 52 from 258 because of the symbol (-) in front of it. Since there is no other numbers with variables 14x is left alone. Hope this helps
Sammy walks at 4 miles an hour for half an hour. This means the walk is 2 miles in 30 minutes.
Candy is going 6 miles an hour, so it will only takes her 1/3 of an hour, or 20 minutes, to cover 2 miles.
So, Candy gets home 10 minutes faster (30-20) than Sammy.
Answer:
B. Step 2 uses the associative property, and step 3 uses the commutative property.
Step-by-step explanation:
The associative property lets you group terms for addition any way you like. It appears that in Step 2, the grouping is ...
4 + (1/6 + 3) + 5/6
The commutative property lets you change the order of any pair of terms involved in addition. It appears that in Step 3, the order of the terms within the group has been swapped.
4 + (3 + 1/6) + 5/6

<em>Comment on associative and commutative properties</em>
What applies to terms in addition applies to factors in multiplication.
