So I don't understand this problem... Solve for g. 25g < 200

Ok. So in Algerbra you are supposed to do some really complicated things. But when it's like that, where the 25 is multiplied by g. You will do the opposite which is dividing. I would recommend some Khan Academy. Even though it can be annoying. It will help you solve problems like this and it will build up your speed. So, summed up you will divide 200 and 25. Which equals 8. Hope that helps!

<h3>What is Unitary Method?</h3>

Unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

Sue spent 1 hour 19 minutes less than Jared

Lucas spent 45 minutes less than Pete.

Pete spent 3 hours reading.

Since, pete spent 3 hours. So, Jared spent

= 3 hours or (180 minutes) - 45 minutes

= 2 hours 15 minutes.

Now, Seu spent = 2 hrs 15 minutes - 1 hour 19 minutes

= 56 minutes

What number should be placed in the box to help complete the division calculation? can someone please do the problem (8587/12) s

disa [49]

Answer:

8587 should be in the box

Step-by-step explanation:

we would see it question as: 12/- 8587

12 goes into 85 7 times, so 7

12 goes into 18 1 time, so 1

12 goes into 67 5 times, so 5

then the remainder is 7

or you further divide to get . 5 8 3333333...

so your answer should be 715r7 or 715.58333

Answer:

$n=\frac{0.5(1-0.5)}{(\frac{0.04}{1.64})^2}=420.25$

And rounded up we have that n=421

Step-by-step explanation:

We know that the sample proportion have the following distribution:

$\hat p \sim N(p,\sqrt{\frac{p(1-p)}{n}})$

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 90% of confidence, our significance level would be given by $\alpha=1-0.90=0.1$ and $\alpha/2 =0.05$ . And the critical value would be given by:

$z_{\alpha/2}=-1.64, z_{1-\alpha/2}=1.64$

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 $ME =\pm 0.04$ 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)

We assume that a prior estimation for p would be $\hat p =0.5$ since we don't have any other info provided. And replacing into equation (b) the values from part a we got:

$n=\frac{0.5(1-0.5)}{(\frac{0.04}{1.64})^2}=420.25$

And rounded up we have that n=421
