29% = 0.29
Multiply 1.89 with 0.29
1.89 x 0.29 = 0.5481
Note that it is a markdown, so subtract 0.55 (rounded) with 1.89
1.89 - 0.55 = 1.34
The spark plug now costs ~ $1.34
hope this helps
Answer: Option C. They're not similar because only one pair of corresponding angles in the two triangles is congruent.
Solution:
The only one pair of corresponding angles in the two triangles is congruent is the angle BGC in ΔCBG and the angle FGE in ΔFEG, because they are vertical angles (opposite by the vertex)
Given:
The two way table.
To find:
The conditional probability of P(Drive to school | Senior).
Solution:
The conditional probability is defined as:

Using this formula, we get
...(i)
From the given two way table, we get
Drive to school and senior = 25
Senior = 25+5+5
= 35
Total = 2+25+3+13+20+2+25+5+5
= 100
Now,


Substituting these values in (i), we get




Therefore, the required conditional probability is 0.71.
