There are 8.89 centimeters in 3.5 inches
The answer is positive because the slope formula is y2 - y1/x2 - x1
By insterting our beautiful numbers we get the equation of: 5 - 3/4 - (-2)
That equals 2/6, which we can then reduce to 1/3. 1/3 is indeed positive. (I know I answered late, but I hope I 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
Answer:
The answer is 104 degrees.
Step-by-step explanation:
M is equivalent to N, which means x is also 104 degrees.
Answer:
The probability that sample mean differ the true greater than 2.1 will be 2.8070 %
Step-by-step explanation:
Given:
Sample mean =46 dollars
standard deviation=8
n=53
To Find :
Probability that sample mean would differ from true mean by greater than 2.1
Solution;
<em>This sample distribution mean problem,</em>
so for that
calculate Z- value
Z=(sample mean - true mean)/(standard deviation/Sqrt(n))
Z=-2.1/(8/Sqrt(53))
Z=-2.1*Sqrt(53)/8
Z=-1.91102
Now for P(X≥2.1)=P(Z≥-1.91102)
Using Z-table,
For Z=-1.91
P(X>2.1)=0.02807
