Answer:
Step-by-step explanation:
Given that a USA Today/Gallup poll conducted between 2010 and 2011 asked a group of unemployed and underemployed Americans if they have had major problems in their relationships with their spouse or another close family member as a result of not having a job (if unemployed) or not having a full-time job (if underemployed).
Let p1 be the proportion of I group and p2 for II group.
a) the hypotheses for evaluating if the proportions of unemployed and underemployed people who had relationship problems were different
(two tailed test)
b) p value = 0.35
A small p value indicates strong evidence against null hypothesis.
Normally significance level would be 5% or 1% or 10% . If p value is above this value, this proves that null hypothesis can be accepted.
Here p = 0.35 implies that there is no significant different between the two proportions.
Answer: If it was the same day, then it was 6:20. But if it was the next day, then i don't know.
Step-by-step explanation:
When the x values are evenly spaced, as they are here, the second differences are constant when the function is quadratic.
1st table:
.. 2 -4 = -2; 1 -2 = -1; 0.5 -1 = -0.5 . . . . first differences
.. -1 -(-2) = 1; -0.5 -(-1) = 0.5 . . . . . . . . . second differences are different
2nd table:
.. 128 -135 = -7; 105 -128 = -23; 72 -105 = -33 . . . . first differences
.. -23 -(-7) = -16; -33 -(-23) = -10 . . . . . . . . . . . . . . . second differences are different
3rd table:
.. -23.2 -(-23.4) = 0.2; -23 -(-23.2) = 0.2 . . . . . first differences are constant. This is a linear function.
4th table:
.. 56 -90 = -34; 26 -56 = -30; 0 -26 = -26; -22 -0 = -22; -40 -(-22) = -18
.. -30 -(-34) = 4; -26 -(-30) = 4; -22 -(-26) = 4; -18 -(-22) = 4 . . . . second differences are constant at 4.
The 4th selection is appropriate.
Answer:
The mistake stems from the assumption that angle dab and abc are both 90 and ad = bc and that the perpendicular bisector of dc is different from the perpendicular bisector to ab because they are the same and abcd is a rectangle.
Step-by-step explanation:
If ∡dab = ∡abc and side ab is equal to side bc which are opposite sides, ten then ab is parallel to bc which means the quadrilateral is parallelogram. Also since two angles of the four angles of the parallelogram are 90 degrees then the parallelogram is a rectangle.
The bisector of one side of a rectangle will also bisect the opposite side of the rectangle. Therefore the bisector of dc is the same as the bisector of ab and it meets ab at the midpoint of ab. Therefore p is now at the midpoint of ab and there are no triangles pad and pbc.
Answer:
not so sure though but I think thats the answer
