Hi there!

The answer is 48. 

To solve this problem, we need to find the unit rate, or the amount of hot dogs he can eat per minute, and multiply that by 12 to find the amount of hot dogs he can eat in 12 minutes. 

First, let's convert and simplify 32 hot dogs per 8 minutes:

= 32/8
= 4
= 4 hot dogs per min

4 hot dogs per minute is our unit rate. 

Now, we should multiply the unit rate by 12:

4 * 12 = 48

So, the answer is 48 hot dogs. 

Hope this helps!

48 since he eats 4 a minute and 4 times 12 equals 48.

Write an algebraic equation to solve for the triangle’s height. Area of the triangle =36.8 inches . Height is x and base is 4.6
Minchanka [31]
The formula to find the Height of a triangle when you have the Area and the base is H = 2 * A/b
if the Area is 36.8 then divide it by 4.6.  You get 8.  put 36.8 in calculator first, then 4.6 = 8
2 x 8 = 16...so the answer should be 16 inches.
2 is in the formula to multiply to the number you get after dividing the base into the Area.

Sergeeva-Olga [200]

Answer:

n=\frac{0.005(1-0.005)}{(\frac{0.001}{1.96})^2}=19111.96  

And rounded up we have that n=19112

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".  

The margin of error is the range of values below and above the sample statistic in a confidence interval.  

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".  

Solution to the problem

In order to find the critical value we need to take in count that we are finding the interval for a proportion, so on this case we need to use the z distribution. Since our interval is at 95% of confidence, our significance level would be given by \alpha=1-0.95=0.05 and \alpha/2 =0.025. And the critical value would be given by:

z_{\alpha/2}=-1.96, z_{1-\alpha/2}=1.96

The margin of error for the proportion interval is given by this formula:  

ME=z_{\alpha/2}\sqrt{\frac{\hat p (1-\hat p)}{n}}    (a)  

And on this case we have that ME =\pm 0.001 and we are interested in order to find the value of n, if we solve n from equation (a) we got:  

n=\frac{\hat p (1-\hat p)}{(\frac{ME}{z})^2}   (b)  

And replacing into equation (b) the values from part a we got:

n=\frac{0.005(1-0.005)}{(\frac{0.001}{1.96})^2}=19111.96  

And rounded up we have that n=19112
