Answer:
the answer for this question is 18 because first of all remember to use the rule 4x-2 to find the last one and you replace it with 5 so 4(5)-2= 20-2=18 so 18 is the correct for the last one and have a great day.
4(3)-2= 12-2=10 for the first one if you wanted to kind of knowing that.

Answer:
The answer is x= 9.9
Step-by-step explanation:
3= x/3.3
Switch sides:
x/3.3 = 3
Multiply both sides by 3.3:
3.3x/3.3 = 3* 3.3
Simplify:
x= 9.9
Hope this helped :)
Answer:
The probability is 0.68
Step-by-step explanation:
We are going to use conditional probability to solve this problem.
We define the following events :
A : '' Alex replaced the starter''
B : ''Alex replaced the battery''
M : ''The engine works''
NM : ''The engine doesn't work''
Given two events A and B, we define the conditional probability:
Where P(A,B) = P(B,A) = P(A∩B) = P(B∩A)
In our problem :
Alex replaced the battery or either the starter ⇒
We need to find
We write :
P(M) = [P(M∩B) ∪ P(M∩A)]
P(M) = P(M∩B) + P(M∩A) - P[(M∩B)∩(M∩A)]
But P[(M∩B)∩(M∩A)] = 0 because he replaced the battery or either the starter
P(M) = P(M∩B) + P(M∩A)
P(M)=0.595+0.03
P(M)=0.625
P(NM)= 1-P(M)=1-0.625=0.375
P(NM)= 0.375
P(NM/B) = 1-P(M/B)=1-0.7=0.3
P(NM/B) = 0.3
