Answer:
The conclusion is True
Step-by-step explanation:
Solution:
- The standard deviation of company s1 = 0.035
- The standard deviation of company s2 = 0.062
- Null Hypothesis : s1^2 = s2^2
- Alternate hypothesis : s1^2 < s2^2
- Criteria to reject Null: M > M_a ( 12 - 1 , 12 - 1 )
- From Tables, M > 2.82
- M - statistics value M = s2^2 / s1^2
- M = (0.062 / 0.035)^2 = 3.14
- M = 3.14 > 2.82 ... Criteria of rejection is met
- Null Hypothesis must be rejected at level of significance a = 0.05
- p value, 1 - 0.965 = 0.035 < 0.05 ( Significance Level )
- The conclusion is True
For each point, add 7 to the x coordinate and take away 1 from the y-coordinate.
<span>I am using a "tick-mark" to show the corresponding point, after "translation" (movement in a straight line). </span>
<span>A(-2, 2) becomes A'(5, 1) </span>
<span>Because all points have been translated in a straight line, in the same direction (the direction [7 -1]) by the same distance, the new figure A'B'C'D' will have the same shape, same size and same orientation as the original image. </span>
<span>It will simply be in a different location on the graph. </span>
<span>If you were to join A with A', B with B', and so on, you would see that all 4 vectors are parallel and are of equal length. </span>
<span>If you were to compare the segment AB (side AB of the original quadrilateral) with the segment A'B' (in the new quadrilateral), you would see that they are parallel (same slope) and have the same length. </span>
<span>Same with the other sides. </span>
<span>Tow figures that are identical (except for their location) are said to be "congruent". </span>
<span>--- </span>
<span>The new rectangle will be far to the right (7 units in x) and a bit below (-1 in y) from the old one. </span>
<span>You should draw the two figures on a graph, and you will see a lot of this very clearly.</span>
Answer: 5/4
Explanation:
We have the same denominator so we can just add the numerator.
= 6/8 + 4/8
=10/8
10/8 can be simplified
=5/4
Answer:
A
Step-by-step explanation:
12 girls for every 5 boys
boys is second so it shouldb be indenomenaotr (bottom)
girls/boys
