Answer:

Hi!

The correct answer is:

D. y= 1.75 + 1.25(x-1)

Step-by-step explanation:

If the charge for first breakfast taco is $1.75. So this is a constant of this function.

y= 1.75 + 1.25(x-1)

Moreover, for each additional taco, we have to charge $1.25 plus.  If the first taco <em>is not</em> an additional taco, then we don't have to count the first taco and it will be represent like:

y= 1.75 + 1.25(x-1)

Then if we replace some values of x on the function we have:

y(1)= 1.75 + 1.25(1-1) =  1.75 + 1.25(0) = 1.75 for the first taco.

y(2)= 1.75 + 1.25(2-1) =  1.75 + 1.25(1) = 3 for the first and the second taco.

and so on..

Answer:

y= 1.75 is the starting contest the additional amount of tacos is X so x*1.25 will give the price of more tacos.

y=1.75+1.25(x+1) is the answer

Y = 3x + 13 <br> y = -2x - 22<br><br> substitution method show work <br><br> pls someone help quick
laiz [17]

Answer:

x = -7

Step-by-step explanation:

3x + 13 = -2x - 22

subtract 13 from both sides

3x = -2x - 35

Add 2x to both sides

5x = -35

Divide each side by 5

x = -7

You want to obtain a sample to estimate a population proportion. At this point in time, you have no reasonable estimate for the
Vesna [10]

Answer:

A sample size of at least 1,353,733 is required.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of .

The margin of error is:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

98% confidence level

So \alpha = 0.02, z is the value of Z that has a pvalue of 1 - \frac{0.02}{2} = 0.99, so Z = 2.327.  

You would like to be 98% confident that you esimate is within 0.1% of the true population proportion. How large of a sample size is required?

We need a sample size of at least n.

n is found when M = 0.001.

Since we don't have an estimate for the proportion, we use the worst case scenario, that is \pi = 0.5

So

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

0.001 = 2.327\sqrt{\frac{0.5*0.5}{n}}

0.001\sqrt{n} = 2.327*0.5

\sqrt{n} = \frac{2.327*0.5}{0.001}

(\sqrt{n})^{2} = (\frac{2.327*0.5}{0.001})^{2}

n = 1353732.25

Rounding up

A sample size of at least 1,353,733 is required.
