Answer: the probability that a measurement exceeds 13 milliamperes is 0.067
Step-by-step explanation:
Suppose that the current measurements in a strip of wire are assumed to follow a normal distribution, we would apply the formula for normal distribution which is expressed as
z = (x - µ)/σ
Where
x = current measurements in a strip.
µ = mean current
σ = standard deviation
From the information given,
µ = 10
σ = 2
We want to find the probability that a measurement exceeds 13 milliamperes. It is expressed as
P(x > 13) = 1 - P(x ≤ 13)
For x = 13,
z = (13 - 10)/2 = 1.5
Looking at the normal distribution table, the probability corresponding to the z score is 0.933
P(x > 13) = 1 - 0.933 = 0.067
The difference is 6 because it is what we get when we subtract 8 and 2.
Final answer: 6
It is the first number line :)
Two angles are called complementary when their measures add to 90 degrees. Two angles are called supplementary when their measures add up to 180 degrees.So the equation to solve this would be simply 90 multiply 2 which gives you the answer of 180 degree in this situation.
Answer:
1/13 and 12/13
Step-by-step explanation:
To answer this question, we need to know the number of cards that are 3 .
Each suite has a single 3 and there are 4 suites.
This means we have 4 cards that are 3
Now, the probability of 3; P(3) would be 4/52 = 1/13
P(of not 3) = 1- probability of 3 = 1-1/13 = 12/13
