Answer:

The term that best describes a figure formed by three segments connecting three non-collinear points is:

Triangle.

Step-by-step explanation:

Step-by-step explanation:

We know that with the help of just one point we can't form any figure.

With the help of two points a line segment can be formed.

And with the help of three points if the three points are collinear a triangle can be formed.

Hence, the term that best describes a figure formed by three segments connecting three non-collinear points is:

Triangle.

Marysya12 [62]

Answer:

The mean is 2.75.

The margin of error is 0.62.

Step-by-step explanation:

In this case, we know the 95% confidence interval, and we want to know the mean and the margin of error.

The mean can be calculated as the average between the upper limit and lower limit:

$\mu=\frac{UL-LL}{2}=\frac{3.37+2.13}{2}=\frac{5.5}{2}=2.75$

The margin of error is the difference between the upper (or lower limit) and the mean. It equals the product between the z-value and the standard deviation divided by the square of the sample size.

It can also be calculated as half the difference of the limits of the confidence interval.

We only have the limits of the confidence interval to calculate the margin of error:

$ME=z\sigma/\sqrt{n}=\frac{UL-LL}{2}=\frac{3.37-2.13}{2}=\frac{1.24}{2}= 0.62$

Suppose 1% of cotton fabric rolls and 4% of nylon fabric rolls contain flaws. Of the rolls used by a manufacturer, 70% are cotto

Amanda [17]

Answer:

0.019 or 1.9%

Step-by-step explanation:

The probability that a randomly selected roll used by the manufacturer contains flaws is determined by the probability of a flawed cotton roll occurring (1% x 70%) added to the probability of a flawed nylon roll occurring (4% x 30%) .

$P(F) = P(C)*P(F_C)+P(N)*P(F_N)\\P(F) = 0.7*0.01+0.3*0.04\\P(F) = 0.019 = 1.9\%$

The probability that a randomly selected roll contains flaws is 0.019 or 1.9%
