On average 20% of the gadgets produced by a factory are mildly defective. I buy a box of 100 gadgets. Assume this is a random sa
Softa [21]

Answer:

a) P(A)=P(x

b) P(A)\approx 0.085

Step-by-step explanation:

The proportion of defective gadgets for this factory is p=0.2.

If a sample of n=100 gadgets is taken from the production, we can model the amount of defectives gadgets in this sample as a binomial random variable.

The probability of having k defectives in the sample can be written as:

P(x=k)=\binom{100}{k}p^k(1-p)^{100-k}

Then, we can write the expression to calculate the probabilities of A: "less than 15 gadgets are mildly defective":

P(A)=P(x

If we approximate this binomial distribtution to a normal distribution, we can calculate the new parameters as:

\mu=np=100*0.2=20\\\\\sigma=\sqrt{np(1-p)}=\sqrt{100*0.2*0.8}=\sqrt{16}=4

The continuity factor is applied for the change from a discrete distribution (binomial) to a continous distribution (normal). Then we have:

P(A)=P(X

Now, we can calculate the probability P(A):

z=(X-\mu)/\sigma=(14.5-20)/4=-5.5/4=-1.375\\\\P(A)=P(X

What is the degree measure of two thirds of a full turn?
Luda [366]
<span>This question requires only one calculation to determine the answer. A full turn is 360 degrees. Therefore, to find the degree measure of two thirds of a full turn, we multiply 360 degrees by 2/3. This gives us 240 degrees.</span>
