Answer: a. 7
Step-by-step explanation: <u>Degrees</u> <u>of</u> <u>Freedom</u> is the number of values "allowed" to vary. For example:
In the experiment above, the sample has 8 tobacco leaves. Two strains will be applied to each leaf. The decision of which strain goes to the right or left is random. Each strain have 7 possible leaves it can be applied, because, for the last, the eight leaf, there is no choice.
Therefore, the degrees of freedom for this experiment is 7.
It can also be calculated as
df = n - 1
df = 8 - 1
df = 7
1) vertical angles theorem
2) transitive property of congruence
Answer:
78%
Step-by-step explanation:
Given the information, we can write:
P(cook) = 52%
P(shop) = 54%
P(cook and shop) = 28%
Now, we need to find P(cook or shop).
We need probability formula for general addition rule, which is:
P(A or B) = P(A) + P(B) - P(A and B)
We can take "cooking" and Event "A" and "shopping" as Event "B".
Thus, we write:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.52 + 0.54 - 0.28
P(A or B) = 0.78
Which is 78%
Answer:
0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.
Step-by-step explanation:
Probability of a defective part:
0.04 of , that is, coming from A.
0.05 of , that is, coming from B. So
0.0444 = 4.44% probability that a part chosen at random (from the sample) was defective.
The planar
density for the (100) plane is
PD100 (Ni)=1/(4R²)=1/(4*0.125²)=16.00 nm-2 = 1.6 x10^19 m-2
the answer is 1.6 x10^19 m-2
