You'll need to subtract 378 from 409

409-378=31

Find the value of x if the perimeter is 24 meters. (the m stands for meters). Be sure to be able to create the equation to solve

barxatty [35]

Answer:

x=2.5

Step-by-step explanation:

P=(3x+1)+(x+1)+(3x+1)+(x+1)

24=3x+1+x+1+3x+1+x+1

24=8x+4

24-4=8x

20=8x

x=20/8

x=2.5

P=(3*2.5+1)+(2.5+1)+(3*2.5+1)+(2.5+1)

P=8.5+3.5+8.5+3.5

P=24

Oksi-84 [34.3K]

First, you need to figure out how many people are paying. Since it is Hank and his two friends, three people will be paying. Next, you need to divide 129.00 by 3. 129/3=43. Each friend will pay exactly $43.00.

In a sample of 1000 randomly, selected consumers who had opportunities to send in a rebate claim form after purchasing a product

Alexxx [7]

Answer: $=(0.2232,0.2768)$

Step-by-step explanation:

The confidence interval for population proportion is given by :-

$p\ \pm z_{\alpha/2}\sqrt{\dfrac{p(1-p)}{n}}$

Given : Sample size : $n=1000$

The proportion of people selected consumers who had opportunities to send in a rebate claim form after purchasing a product said they never did so = $\dfrac{250}{1000}=0.25$

Significance level : $1-0.95=0.05$

Critical value : $z_{\alpha/2}=1.96$

Now, the 95% confidence Interval for the true proportion of such consumers who never apply for a rebate will be :-

$0.25\ \pm (1.96)\sqrt{\dfrac{0.25(1-0.25)}{1000}}\\\\\approx0.25\pm0.0268\\\\=(0.2232,\ 0.2768)$

Hence, a confidence Interval for the true proportion of such consumers who never apply for a rebate .
