Answer:
A lies along the positive x-axis and B lies along negative x - axis
.
Step-by-step explanation:
They tell us that we have two vectors, A and B. And they give us a series of conditions for this, now, what would be the correct possibility.
A lies along the positive x-axis and B lies along negative x - axis
.
This is because when both vectors will be in x axis but opposite to each other, then the angle between them will be 180 ° and cos180 ° is -1.
Answer:
1. 14%
2. 98%
3. 52%
4. 13%
5. 39%
6. 28%
7. 20%
8. 37%
9. 17%
10. 19%
Step-by-step explanation:
To get a percentage divide the small number by the big number and then multiply by 100.
1. 28/200 = 0.14 * 100 = 14
2. 931/950 = 0.98 * 100 = 98
3. 364/700 = 0.52 * 100 = 52
4. 13/100 = 0.13 * 100 = 13
5. 273/700 = 0.39 * 100 = 39
6. 161/575 = 0.28 *100 = 28
7. 200/1000 = 0.2 * 100 = 20
8. 68/400 = 0.37 * 100 = 37
9. 68/400 = 0.17 * 100 = 17
10. 95/500 = 0.19 * 100 = 19
Answer:
1. A is the null hypothesis. The null hypothesis is the statement in which everything is operating as expected; nothing unusual is going on.
2. C is the alternative hypothesis. The problem says that you are looking to see whether or not the machine is filling with an average of 24 ounces, so it could be over or under filling. B only accounts for under filling.
