Answer:

16

Step-by-step explanation:

First, you have to follow the order of operations. (PEMDAS) So you would simplify the numbers inside of  the parenthesis, (4*2), and (5-3). The equation then becomes 20 - (8) / (2). Next, you do multiplication and division next, since  there is no exponent. 20 - 4. You then simplify the rest by subtracting. 20 - 4 = 16. There is your answer.

An assembly line inspector inspected 340 machine parts. 323 of the parts passed inspection. What percent of the machine parts di
tester [92]

Answer:

5% did not pass inspection

Step-by-step explanation:

Given

Inspected= 340

Passed = 323

Required

Determine the percentage of parts that didn't pass inspection.

First, we need to calculate the number of those that didn't pass inspection.

Failed = Inspected - Passed

Failed = 340 - 323

Failed = 17

Next, we calculate the percentage as follows:

\% = \frac{Failed}{Inspected} * 100\%

The above formula is derived by dividing the number of parts that didn't pass inspection by the total machine inspected, then multiplied by 100%

So:

\% = \frac{17}{340} * 100\%

\% = \frac{17 * 100\%}{340}

\% = \frac{1700\%}{340}

\% = 5\%

<em>5% did not pass inspection</em>
