You found the prime factorization of the number 73 explain how you can check your answer

antoniya [11.8K]

9514 1404 393

Explanation:

You can check your answer by making sure that each of the primes you found is actually a prime. (Compare to a list of known primes, for example.) After you have determined your factors are primes, multiply them together to see if the result is 73. If so, you have found the correct prime factorization.

Additional comment

73 is prime, so its prime factor is 73.

73 = 73

What is the radius of a circle with an area of 50.24 cubic inches? Use 3.14 for pi. Enter your answer in the box.

miss Akunina [59]

Answer:

r=4

Step-by-step explanation:

Area of a circle is

A = pi* r^2

We know the area and 3.14 = pi

50.24 = 3.14 * r^2

Divide each side by 3.14

50.24/3.14 =3.14 /3.14 *r^2

16 = r^2

Take the square root of each side

sqrt(16) = sqrt(r^2)

4 =r

Arturiano [62]

Answer:

d. t distribution with df = 80

Step-by-step explanation:

Assuming this problem:

Consider independent simple random samples that are taken to test the difference between the means of two populations. The variances of the populations are unknown, but are assumed to be equal. The sample sizes of each population are n1 = 37 and n2 = 45. The appropriate distribution to use is the:

a. t distribution with df = 82.

b. t distribution with df = 81.

c. t distribution with df = 41.

d. t distribution with df = 80

Solution to the problem

When we have two independent samples from two normal distributions with equal variances we are assuming that

$\sigma^2_1 =\sigma^2_2 =\sigma^2$

And the statistic is given by this formula:

$t=\frac{(\bar X_1 -\bar X_2)-(\mu_{1}-\mu_2)}{S_p\sqrt{\frac{1}{n_1}+\frac{1}{n_2}}}$

Where t follows a t distribution with $n_1+n_2 -2$ degrees of freedom and the pooled variance $S^2_p$ is given by this formula:

$\S^2_p =\frac{(n_1-1)S^2_1 +(n_2 -1)S^2_2}{n_1 +n_2 -2}$

This last one is an unbiased estimator of the common variance $\sigma^2$

So on this case the degrees of freedom are given by:

$df= 37+45-2=80$

And the best answer is:

d. t distribution with df = 80

Please take a look at the imageeeeeeeeeeeee

Answer:

I'm not alone

It's just me and your ghost

And this cripplin' depression

I thought I learned my lesson

But I threw out my phone

And I burned all your clothes

And now I'm not alone

It's just me and your ghost

[Verse 1]

I got four red bottoms up in flames at my place now (Place now)

I burned three Chanel dresses, three words we don't say now (Say now)

And it's hard not to drink when it's the one thing I think about

It's a lot of spiders in the attic, I don't mean to be dramatic

But I think it's kinda tragic who we magically became now

[Chorus]

I'm not alone

It's just me and your ghost

And this cripplin' depression

I thought I learned my lesson

But I threw out my phone

And I burned all your clothes

And now I'm not alone

It's just me and your ghost

[Post-Chorus]

Me and your ghost

Me and your ghost (Yeah)

[Verse 2]

Tell me what I'm s'posed to do with all these pictures on my iPhone

Even all them videos only you and I know

You never cared about me, you just care about the likes though

Every time you pop up, you should see my stupid eye roll

I can't even kick it with the homies that we both know

I can't even vist with any places that we used to go

Now all I got is just the memories of us though

Burn it all down to the ground with your ghost

[Chorus]

I'm not alone

It's just me and your ghost

And this cripplin' depression

I thought I learned my lesson

But I threw out my phone

And I burned all your clothes

And now I'm not alone

It's just me and your ghost

[Post-Chorus]

Me and your ghost

[Bridge]

I wish I could take back summer nights

Erase all the vibes

Leave the memories out to dry

Delete forever, no archive

Take the words you said to me

Hold on to them intentionally

I know that eventually

I'ma set fire to the one thing I love the most

Burn it all to the ground with your ghost

[Chorus]

I'm not alone

It's just me and your ghost

And this cripplin' depression

I thought I learned my lesson

But I threw out my phone

And I burned all your clothes

And now I'm not alone

It's just me and your ghost

[Post-Chorus]

Me and your ghost
