Let x and y be the two unknown numbers. The first statement says that one number say x, is 6 more than twice another, say, y. If we express this mathematically, that would be:

x = 6 + 2y   or that could be   y = 6 + 2x

The second statement says that the sum of both numbers, x and y, is 51. That would be

x + y = 51

From the choices, the answer would be
<span>B. y = 2x + 6 and x + y = 51</span>

Aleks04 [339]

Answer:

99% Confidence interval: (0.185,0.375)                                                  

Step-by-step explanation:

We are given the following in the question:

Sample size, n = 150

Number of cars that have faulty catalytic converters, x = 42

\hat{p} = \dfrac{x}{n} = \dfrac{42}{150} = 0.28

99% Confidence interval:

\hat{p}\pm z_{stat}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

z_{critical}\text{ at}~\alpha_{0.01} = \pm 2.58

Putting the values, we get:

0.28\pm 2.58(\sqrt{\frac{0.28(1-0.28)}{150}}) = 0.28\pm 0.095\\\\=(0.185,0.375)

The​ 99% confidence interval for the true proportion of new cars with faulty catalytic converters is​ (0.185,0.375)
