Answer:

(a) none

Step-by-step explanation:

The given equations are the same except for the right-side constant. In order for there to be any solution, the left-side expression would have to have two values simultaneously. It cannot.

These equation are described as "inconsistent." There are no solutions.

_____

<em>Additional comment</em>

Subtracting the second equation from the first gives the result ...

0 = 2 . . . . false

There are no values of the variables x and y that will make this be true.

Answer:

None

since the slopes are equal, it's either infinite or none.

since the ratios of Ys and Xs is 1, 18/16 should be 1 to say we have infinite answers. since it's not, the is no solution at all.

Gary and Jessica exercise for a total of 18 hours per week. Jessica exercises 2 less than 3 times the hours that Gary exercises.

horsena [70]

<h3>Answer: 5</h3>

Work Shown:

g = number of hours that Gary exercises

3g-2 = number of hours that Jessica exercises

(g) + (3g-2) = 18

4g-2 = 18

4g = 18+2

4g = 20

g = 20/4

g = 5

Gary exercises 5 hours per week.

The volume of the pyramid is $726 \mathrm\ {cm}^{3}$

Explanation:

The height of the square pyramid is 18 cm

The base of the square pyramid is 11 cm

The volume of the square pyramid can be determined using the formula,

$V=\frac{1}{3} b^{2} h$

Substituting $b=11$ and $h=18$ in the formula, we have,

$V=\frac{1}{3} (11)^{2} (18)$

Simplifying, we have,

$V=\frac{1}{3} (121)(18)$

Multiplying, we get,

$V=\frac{2178}{3}$

Dividing, we get,

$V=726 \ cm^3$

Thus, the volume of the pyramid is $726 \mathrm\ {cm}^{3}$

Answer:

$n=(\frac{2.58(1000)}{50})^2 =2662.56 \approx 2663$

So the answer for this case would be n=2663 rounded up to the nearest integer

Step-by-step explanation:

We have the following info:

$ME = 50$ margin of error desired

$\sigma = 1000$ the standard deviation for this case

The margin of error is given by this formula:

$ME=z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$ (a)

And on this case we have that ME =50 and we are interested in order to find the value of n, if we solve n from equation (a) we got:

$n=(\frac{z_{\alpha/2} \sigma}{ME})^2$ (b)

The critical value for 99% of confidence interval now can be founded using the normal distribution. The significance is $\alpha=0.01$ . And for this case would be $z_{\alpha/2}=2.58$ , replacing into formula (b) we got:

$n=(\frac{2.58(1000)}{50})^2 =2662.56 \approx 2663$

So the answer for this case would be n=2663 rounded up to the nearest integer
