Answer:

$x=\frac{5\pi}{4}$

Step-by-step explanation:

We want to solve;

$\cscx=-\sqrt{2}$ in the 3rd quadrant

Recall that;

$\sin x=\frac{1}{\csc x}$

We use the reciprocal ratio to get;

$\sin x=-\frac{\sqrt{2}}{2}$

In the third quadrant the solution is

$x=\pi+\sin^{-1}(\frac{\sqrt{2} }{2} )$

$x=\pi+\frac{\pi}{4}$

$x=\frac{5\pi}{4}$

NeX [460]

Answer:

The experimental and theoretical probabilities are considerably different. This has to do with the small number of trials. For a higher number of trials, the experimental probability should be very close to the theoretical probability of 0.1429.

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

Theoretical probability:

The theoretical probability is calculated without considering previous trials.

Experimental probability:

Calculated considering previous trials.

For a small number of trials, these probabilities can differ, but the experimental probability approximates the theoretical as the number of trials increase.

Seven different names are written into sticks and placed into a cup.

So the theoretical probability of choosing Grace is:

$p_T = \frac{1}{7} = 0.1429$

A stick is chosen 100 times,out of which the name Grace is chosen 23 times.

So the experimental probability is:

$p_E = \frac{23}{100} = 0.23$

How do the theoretical probability and experimental probability compare?

The experimental and theoretical probabilities are considerably different. This has to do with the small number of trials. For a higher number of trials, the experimental probability should be very close to the theoretical probability of 0.1429.

Help me please can you model this for me I need SERIOUS HELP ASAP? And correct my answer PLEASE and thank you!

What do I need to find?

Your answer is correct.

What information do I need to use?

100% = 240 miles, she has already driven 15% of 240, so she has driven x miles.

How will I use the information?

Set up a proportion. If she has already driven 15% out of 100% of the distance, then you should write $\frac{15}{100}$ for the first fraction. This is proportional to $\frac{x(miles)}{240(miles)}$ . This means that $\frac{15}{100} = \frac{x}{240}$ . Wait, but this is confusing. How on Earth do we solve it? Let's take a closer look. If $\frac{x}{240}$ is supposed to equal 15/100, then this means that x/240 divided by 15/100 should give us the answer. So, even though it looks complicated, all you have to do is cross multiply like this:

$\frac{15}{100} = \frac{x}{240} --> 240 * 15 = 100x --> 3600 = 100x$

Now isolate x:

$\frac{3600}{100} = \frac{100x}{100}$

So x = 36, which means she has already driven 36 out of 240 miles. Lucia still has to drive 204 miles to reach her destination.

1.) In this case, 56 = 100% and 25% of the sandwiches were tuna. This means that 75% of the sandwiches were not. If $\frac{25}{100} = \frac{x}{56}$ and you use the same method above, x is equal to 14. If 14 is 25% then that means the other 75% = 14 * 3. So 42 sandwiches were not tuna.

2.) $\frac{60}{100} = \frac{x}{450}$

--> $27000 = 100x$

---> $\frac{27000}{100} = \frac{100x}{100}$

He still has $270 left to pay.
