Answer:
0% probability cab tires depths would be shallower than 0.25cm.
Step-by-step explanation:
Problems of normally distributed samples can be solved using the z-score formula.
In a set with mean 
and standard deviation 
, the zscore of a measure X is given by:
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
In this problem, we have that:
What is the probability cab tires depths would be shallower than 0.25cm.
This probability is the pvalue of Z when X = 0.25. So
has a pvalue of 0.
0% probability cab tires depths would be shallower than 0.25cm.
Is this a true/false or do you need an actual mathematical answer?
i will edit my this to answer your question.
I'm just not exactly sure what you are asking :-/
Answer:
μ = 1.877
Step-by-step explanation:
Data provided in the question:
Number of data samples, n = 10
Data: 2.18, 2.03, 1.56, 1.09, 1.56 ,2.28 ,1.62 ,2.02 ,2.11 ,2.32
Now,
Mean is calculated using the formula as:
Mean, μ = 
or
Mean, μ = 
or
Mean , μ = 
or
Mean , μ = 1.877
Answer:
The other leg of the triangle is 12.
Step-by-step explanation:
Given:
Hypotenuse of triangle is 13 and a leg(Leg1) is 5.
Let, the other leg of the triangle (Leg2) be 
.
Now, putting the formula:
⇒ 
⇒
⇒
⇒
Taking square root both sides
⇒
⇒
.
Therefore, the other leg of the triangle is 12.
