zhannawk [14.2K]

Answer:

for 0.5 pounds size, we have 7.5

for 0.25 pounds size, we have 15

Step-by-step explanation:

Here, we want to calculate the number of each hamburger size that could be made

for 0.5 pounds size, we have that;

3.75/0.5 = 7.5

for 0.25 pounds, we have;

3.75/0.25 = 15

The water diet requires you to drink two cups of water every half hour from the time you get up until you go to bed, but otherwi

Elan Coil [88]

Answer:

$7-3.182 \frac{13.638}{\sqrt{4}}= -14.698$

$7+3.182 \frac{13.638}{\sqrt{4}}= 28.698$

Step-by-step explanation:

For this case we have the following info given:

Weight before diet 180 125 240 150

Weight after diet 170 130 215 152

We define the random variable $D = before-after$ and we can calculate the inidividual values:

D: 10, -5, 25, -2

And we can calculate the mean with this formula:

$\bar X= \frac{\sum_{i=1}^n X_i}{n}$

And the deviation with:

$s= \sqrt{\frac{\sum_{i=1}^n (X_i- \bar X)^2}{n-1}}$

And after replace we got:

$\bar D= 7, s_d = 13.638$

And the confidence interval for this case would be given by:

$\bar D \pm t_{\alpha/2} \frac{s_d}{\sqrt{n}}$

The degrees of freedom are given by:

$df = n-1= 4-1=3$

For the 95% of confidence the value for the significance is $\alpha=0.05$ and the critical value would be $t_{\alpha/2}= 3.182$ . And replacing we got:

$7-3.182 \frac{13.638}{\sqrt{4}}= -14.698$

$7+3.182 \frac{13.638}{\sqrt{4}}= 28.698$

What is the solution to this system: 4x+9y=28 - 4x-y=-28

Degger [83]

Answer:

x = 7

y = 0

Step-by-step explanation:

→To solve this, you can use the elimination method. To do this, you must have one set of variables that can cancel each other out. In the problem given, we already have positive 4x and -4x, making them cancel out:

4x + 9y = 28

-4x - y = -28

__________

8y = 0

y = 0

→Plug in 0 for y, into an equation:

-4x - 0 = -28

-4x = -28

x = 7
