Three machines A, B, and C produce 55%, 25% and 20% respectively. The percentages of defective output are 3.5%, 4.5% and 5.5%. I
pishuonlain [190]

We are given the following information concerning the three production machines;

\begin{gathered} Of\text{ the total production;} \\ A=55\text{ \%}=0.55 \\ B=25\text{ \%}=0.25 \\ C=20\text{ \%}=0.20 \end{gathered}

Also, we are given the percentage of defective output as follows;

\begin{gathered} A=3.5\text{ \%}=0.035 \\ B=4.5\text{ \%}=0.045 \\ C=5.5\text{ \%}=0.055 \end{gathered}

Therefore, if an item is selected randomly, the probability that the item is defective would be;

\begin{gathered} P\lbrack defective\rbrack=(0.55\times0.035)+(0.25\times0.045)+(0.20\times0.055) \\ P\lbrack\text{defective\rbrack}=0.01925+0.01125+0.011 \\ P\lbrack\text{defective\rbrack}=0.0415 \end{gathered}

ANSWER:

The probability that the item is defective would be 0.0415

What basic trigonometric identity would you use to verify that
Dafna1 [17]

Given the equation:

\frac{\sin^2x+\text{cos}^2x}{\cos x}=\sec x

Let's determine the trigonometric identity that you could be used to verify the exquation.

Let's determine the identity:

Apply the trigonometric identity:

\sin ^2x+\cos ^2x=1

\cos x=\frac{1}{\sec x}

Replace cosx for 1/secx

Thus, we have:

\begin{gathered} \frac{\sin^2x+\cos^2x}{\frac{1}{\sec x}} \\  \\ =(\sin ^2x+\cos ^2x)(\sec x) \\ \text{Where:} \\ (\sin ^2x+\cos ^2x)=1 \\  \\ We\text{ have:} \\ (\sin ^2x+\cos ^2x)(\sec x)=1\sec x=\sec x \end{gathered}

The equation is an identity.

Therefore, the trignonometric identity you would use to verify the equation is:

\cos ^2x+\sin ^2x=1

ANSWER:

\cos ^2x+\sin ^2x=1

What are the slope and y intercept of the linear function? Please help
kow [346]
FIND THE SLOPE
The line passes through (0,1) and (2,0)
Use formula of the slope to find the slope
m = (y₂ - y₁)/(x₂ - x₁)
m = (0-1)/(2-0)
m = -1/2
The slope is -1/2

FIND THE Y-INTERCEPT
The y-intercept is the value of y when the line intersects y axis. The line intersects y axis in point (0,1). The value of y is 1. So the y-intercept is 1.
