Answer: 0.05

Step-by-step explanation:

Given : To ensure the quality of the shipment, he selected a random sample of 300 cups and inspected them for defects. He found 15 to be defective.

i.e. sample size : n= 300

sample proportion : \hat{p}=\dfrac{15}{300}=0.05

The best estimate for population proportion is the sample proportion.

Therefore, the estimated proportion defective in the population : 0.05

If 5a+b=14 then a = what<br> explain how you got it pls
Trava [24]

Answer:

a = \frac{14 - b}{5}

Step-by-step explanation:

The rule to know and follow is:

You can add, subtract, multiply or divide by anything so long as the same thing is done to both sides of the equals sign;

5a + b = 14

If we want to get: "a = ...", then we use the rule to isolate the variable a on one side of the equation;

Firstly, we subtract b from both sides:

5a + b - b = 14 - b

5a = 14 - b

Then, divide both sides by 5:

\frac{5a}{5} = \frac{14 - b}{5} \\\\ a = \frac{14 - b}{5}
