Consider a manufacturing process with a quality inspection station. In the past, 10% of parts are defective. As soon as one defe
Kruka [31]

Answer:

0.9

Step-by-step explanation:

10% is equal to 0.1

The probability of having defective parts in a pile of parts is 0.1

Before the process is stopped, 1 part has to be defective.

In a pile of 9 parts, the probability that a part is defective 0.1 of 9, which is = 0.9 hence, approximately one (1) part will be defective in a pile of 9 parts and the process will be stopped.

Since there was no defective part among the first 6 parts, P(d) was 0

That is, probability of a defective part was zero.

Triangle HIJ is dilated by a scale factor of 55 to form triangle H'I'J'. Side I'J' measures 7575. What is the measure of side IJ
kvasek [131]

Answer:

If triangle HIJ is dilated about the center of the triangle to create triangle H'I'J', dilated line A'B' will be parallel to AB.Option (D) is correct.

Given:

The options are as follows,

(A). be perpendicular to AB.

(B). lie on the same line as AB.

(C). shift four units to the left.

(D). be parallel to AB.

Step-by-step explanation:

If we dilate triangle HIJ then the dilated triangle  is bigger than the triangle HIJ.

The triangle HIJ is similar to triangle  to each other.

So the line  is parallel to side AB.

Find the average value of the function over the given interval. (Round your answer to three decimal places.) f(x) = −sin x, [0,
deff fn [24]

Answer with Step-by-step explanation:

We are given that

f(x)=-sin x

[0,\infty]]

Average value of the function is given gy

f_{avg}=\frac{1}{b-a}\int_{a}^{b}f(x)dx=\frac{1}{\pi-0}\int_{0}^{\pi}-sinx dx

f_{avg}=\frac{1}{\pi}[cosx]^{\pi}_{0}

Using the formula

\int sin xdx=-cos x

f_{avg}=\frac{1}{\pi}(cos\pi-cos0)

f_{avg}=\frac{1}{\pi}(-1-1)=-\frac{2}{\pi}

f(x)=f_{avg}

-sinx=-\frac{2}{\pi}

sinx=\frac{2}{\pi}

x=sin^{-1}(\frac{2}{\pi})=0.69radian
