y = 3(x - 5)(x - 2) ← expand factors using FOIL

  = 3(x² - 7x + 10) ← distribute parenthesis by 3

y = 3x² - 21x + 30 ← in standard form

A local company wants to evaluate their quality of service by surveying their customers.
stich3 [128]

Answer: b. 0.98

Step-by-step explanation:

The formula to find the maximum error of the estimated mean :

E=z^*\dfrac{\sigma}{\sqrt{n}}            (1)

, where \sigma = standard deviation

n= Sample size

z* = Critical z-value.

As per given , we have

\sigma=5

n=100

Critical value for 95% confidence interval = z*=1.96

Put these values in the formula (1), we get

E=(1.96)\dfrac{5}{\sqrt{100}}

E=(1.96)\dfrac{5}{10}=0.98

Hence, the maximum error of the estimated mean quality for a 95% level of confidence is 0.98.

Therefore , the correct answer is b. 0.98 .

Why is it important to consider scale when graphing inequalities?
tigry1 [53]
<span>If two numbers on a graph differ by 1, without scale, the amount of inequality could vary infinitely. If the scale is 2, a difference of 1 is half the scale amount, but if the scale is 1000, the difference may be negligible. It is the scale that shows the degree to which the entries differ.</span>
