The following percentages of the data fall within the given numbers of standard deviation:
Therefore, 68% of the data will fall within one standard deviation.
Answer:
13.125
Step-by-step explanation:
Since the triangles are congruent, you would get the equation 4z-7=11z-112.
Then, you would subtract 4z from each side, leaving behing -7=8z-112. Then, you would add 112 to each side, getting 105=8z. Divide both sides by 8, and your answer is z=13.125
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
Percent means parts out of 100
x%=x/100
90/270=x/100
times both sides by 100
9000/270=x
33.333333333333=x
roound to tenth
33.3
answer is 33.3%
