A geologist examines 16 water samples for magnesium concentration. The mean magnesium concentration for the sample data is 0.731 cc/cubic meter with a standard deviation of 0.0865. Determine the 80% confidence interval for the population mean magnesium concentration. Assume the population is approximately normal.

no thx

Step-by-step explanation:

I can hear you but I won't

Some look for trouble while others don't

There's a thousand reasons I should go about my day

And ignore your whispers which I wish would go away, oh

Whoa

You're not a voice, you're just a ringing in my ear

And if I heard you, which I don't, I'm spoken for I fear

Everyone I've ever loved is here within these walls

I'm sorry, secret siren, but I'm blocking out your calls

I've had my adventure, I don't need something new

I'm afraid of what I'm risking if I follow you

Into the unknown

Into the unknown

Into the unknown

(Oh)

(Oh)

What do you want? 'Cause you've been keeping me awake

Are you here to distract me so I make a big mistake?

Or are you someone out there who's a little bit like me?

Who knows deep down I'm not where I'm meant to be?

Every day's a little harder as I feel my power grow

Don't you know there's part of me that longs to go

Into the unknown

Into the unknown

Into the unknown

(Oh)

(Oh)

Whoa

Are you out there?

Do you know me?

Can you feel me?

Can you show me?

oh

(Ah) oh

(Ah) oh

(Ah) oh

(Ah) oh

(Ah) oh

Where are you going? Don't leave me alone

How do I follow you

Into the unknown?

x = 25

step-by-step explanation:

a^2+b^2=c^2

7^2+24^2=c^2

49+576=625

sqrt625=25

x=25

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
