Suppose a shipment of 400 components contains 68 defective and 332 non-defective computer components . From the shipment you tak
1 answer:
Answer:
The calculated standard deviation for the defective components in this sample is 1.88.
Step-by-step explanation:
The sampling is conducted with replacement, indicating that each trial is independent, allowing the use of the binomial probability distribution for this question.
Binomial probability distribution
This calculates the probability of achieving exactly x successes over n independent trials, with p being the success probability.
The expected value for the binomial distribution can be expressed as:
The standard deviation for the binomial distribution is given by:
68 defective parts out of 400:
This indicates that
From the total shipment, you select a random sample of 25.
<pThis implies thatCalculating the standard deviation for defective parts in the sample:
The standard deviation for the defective parts in the sample is 1.88.

Response:
C. 50.24 inches
Detailed explanation:
The area of a circle can be expressed with . To determine the circumference, knowing the radius is essential; thereafter, we can substitute that value into the circumference formula
. Hence, to ascertain the radius, we observe that:
As a result, the circumference is:
, which approximates the choice C) 50.24 inches.

We apply the slope formula by substituting the given points.
Here, x2 equals 5 and x1 equals -2; y2 equals -3 and y1 equals 6.
Thus, the line's slope is -9 divided by 7.
