A machine fills 24-ounce (according to the label) boxes with cereal. The amount deposited

1 answer:

7 0

Answer: We do not know the mean  but we do know the standard deviation which is 0.25 ounces. The normal distribution plot below shows the shaded

region at approximately 5% of the area of the total Gaussian distribution.

From a Table we find that 5% is a z = -2.57 and so the mean must be 2.57

multiplied by 0.25 ounces = 3.57  0.25 = 0.643 ounces. The mean value

of box must be 0.643 ounces above the declared 24 ounces. Thus,

Mean value =  = 24.643 ounces

nirvana33 [79]

Answer:

the answer is 240

Step-by-step explanation:

If 4% are defective, then out of a batch of 250, the number of defective is

4% x 250 = 4/100 x 250 = 10 defective

So, the number of not defective is 250 - 10 = 240 good!

loris [4]

Answer:

110 in²

Step-by-step explanation:

Area of trapezoid formula:

A = (b₁ + b₂)h/2

Substitute the values on the sketch and find the area:

A = (9 + 13)*10/2 = 110 in²

A spinner numbered 1 through 12 is spun. Find the probability that

anastassius [24]

Answer:

$\dfrac{1}{6}$

Step-by-step explanation:

Let A be the event of getting an odd number.

P(A) be the probability of getting an odd number.

Total odd numbers here are 6 i.e. $\{1,3,5,7,9,11\}$

Here, total numbers in the game are 12 i.e $\{1,2,3,....,12\}$ .

Formula for probability of an event E can be observed as:

$P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}$

$P(A) = \dfrac{6}{12}\\\Rightarrow \dfrac{1}{2}$

Let B be the event of getting 11.

P(B) be the probability of getting 11.

Total number of possible cases is 1.

$P(B) = \dfrac{1}{12}$

$P(A \cap B)$ is the probability that we get 11 and an odd number.

Possible number of cases = 1

$P(A\cap B) = \dfrac{1}{12}$

P(B/A) is the probability that we get an 11 given that it is an odd number.

$P(B/A) = \dfrac{P(A \cap B)}{P(A)}\\\Rightarrow \dfrac{\dfrac{1}{12}}{\dfrac{1}{2}}\\\Rightarrow \dfrac{1}{6}$

Hence, P(B/A) = $\dfrac{1}{6}$
