Answer:
1.436 or this=−2.436
Step-by-step explanation:
2/3 = (z - 6) / 15
cross multiply
3(z - 6) = 2(15)
3z - 18 = 30
3z = 30 + 18
3z = 48
z = 48/3
z = 16 <===
Based on the relative frequency and the number of times the experiment is to be performed, the number of times Event A should occur is 10 times.
<h3>How many times should Event A occur?</h3>
The relative frequency in this regard is 1/3.
The number of times it will occur can be found as:
= Relative frequency x Number of times event was performed
Solving gives:
= 1/ 3 x 30
= 10 times

Answer:
59) not similar
60)
Step-by-step explanation:
59) The ratios of the side lengths shown cannot be reduced. They are different, so the triangles are not similar.
7:8:12 ≠ 6:7:11
__
60) The side length ratios both reduce to 8:7:10, so the triangles are similar.
∆ABC ~ ∆JKL
The scale factor is LJ/CA = 25/20 = 5/4. (Multiplying ABC by 5/4 will give JKL.)
