telo118 [61]

Given that 4000 items are checked in one month, let the number of detective items be represented as y.

Quality control finds on average that 0.026% of the items in the factory are detective. This implies that

\text{Number of }\det ective\text{ items = }\frac{\text{0.026}}{100}\times\text{Total number of items checked}

When 4000 items are checked, we have the number of detective items to be evaluated as

\begin{gathered} \text{Number of }\det ective\text{ items = }\frac{\text{0.026}}{100}\times\text{Total number of items checked} \\ y=\frac{0.026}{100}\times4000 \\ \Rightarrow y=1.04 \end{gathered}

Hence, the number of detective items is 1.04.

b) y= 5/x What happens to the value of y if the value of x triples? Select your answer. A. x2 B. x3 C. /2 D. /3
jeyben [28]

Answer:

D.)

Step-by-step explanation:

y = 5/x

so when the value of x triples, the new X becomes;

X = 3x

So,

Y = 5/ X

=> Y = 5/3x

=> Y = 1/3 . 5/x

=> Y = 1/3 . y

so the new value of y ( Y ) is 1/3 times original y.

Hence, D. is the answer
