Automobile mechanics conduct diagnostic tests on 150 new cars of particular make and model to determine the extent to which they
galben [10]

Answer: 0.0944

Step-by-step explanation:

Given : Sample size of cars : n= 150, sample size is greater than 30 , so we use z-test.

Number of cars tested do have faulty catalytic converters =42

Then the proportion of cars   have faulty catalytic converters : \hat{p}=\dfrac{42}{150}=0.28

Critical value of z for 99% confidence level : z_{\alpha/2}=2.576

Formula for Margin of error :

E=z_{\alpha/2}\sqrt{\dfrac{\hat{p}(1-\hat{p})}{n}}

E=(2.576)\sqrt{\dfrac{0.28(1-0.28)}{150}}\\\\=0.0944377199216\approx0.0944\ \text{Rounded to four decimal places}

Hence, the required margin of error = 0.0944

Simpligy the expression 7(x+7)-3(x+3)
Irina18 [472]

We will use the distributive property, where a(b+c) = ab+ac and a(b-c) = ab-ac.

7(x+7)-3(x+3)

=7x+49-(3x+9)

=4x+40

Therefore, the simplified expression is 4x+40.
