Answer:
Step-by-step explanation:
- 30 > 6( 2/3z+1/3)
- 30 > 6(2/3z) + 6(1/3)
- 30 > 4z + 2
- 28 > 4z
- 28/4 > z
- 7 > z
- z < 7
160 km - 100%
100%+30%=130%
160*130%:100%=208 (km) - <span>the number sought</span>
The value of cumulative frequency is the sum of all previous frequencies. We should have 26 at the end of the table because all frequency add up to 26
To graph the cumulative frequency, we would need the plots.
Use the end of value range against the cumulative frequency valueRange 40-49, use the value 49 against the cumulative frequency 1
(49, 1)(59, 3)(69, 5)(79, 12)(89, 21)(99, 26)
Plot these on graph and connect them as a curve.
Answer:
A) Similar - AA
Step-by-step explanation:
2 angles are already congruent, so the last angles are also congruent. This means the triangles are similar because their respective angles are congruent. The triangles are not congruent because the sides are not congruent.
