Hi!

<u>Given these two equations:</u>

x = y + 8

x + 4 = 2(y + 4)

We want to solve using the substitution method. Knowing that x is equal to y + 8, we can simply plug in 'y + 8' in for x in the second equation, like so:

(y+8)+4=2(y+4)

Combine like terms on both sides:

y+12=2y+8

Subtract y from both sides:

12=y+8

Subtract 8 from both sides:

y=4

Now, we can simply plug the y value in to the first equation, and solve for x:

x=4+8

Simplify:

x=12

<h3>Therefore, x is equal to 12 and y is equal to 4.</h3>

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 .
