Answer:
Answer:
Option 1, by $851.70
Step-by-step explanation:
Option 1 total:
$8000 + $765.44*5*12 = $53926.40
Option 2 total:
$8000 + $626.25*4*12 + 0.38*$43995 = $54778.10
The difference:
$54778.1 - $53926.40 = $851.70
As we see the option 1 is cheaper by $851.70
Correct answer choice is the last one

Answer:
Step-by-step explanation:
a) Estimate for population mean = Sum/n =
b) Variance = 0.099208
Std dev = 0.314974
Std error = 0.0950
For 95% margin of error = 1.96*Std error
=0.1861
Confidence interval = 
Interpretation of confidence interval:
A) if repeated samoles are taken, 95% of them will have a sample pH of rain water between [ ] & [ ].
For 99% CI, z value = 2.59
Conf interval = (4.6790, 5.1710)
C)if repeated samoles are taken, 99% of them will have a sample pH of rain water between [ ] & [ ].
As the level of confidence increases l, the width of the interval[ increases] this makes sense since the [ margin of error] [increases]
Answer:
No
Step-by-step explanation:
plug the numbers into Pythagorean theorem
c^2 =a ^2 + b^2
28^2 = 20^2 + 19^2
784 = 400+361
784 = 761
No its not
Answer:
34,5 ?? I am not good at this but I did 92-23 that's 69 ÷ 2 = 34.5 ?
It costs around $0.04 to send one text message.
Using unitary method, the cost of sending 92 text messages = $3.68
hence the cost of sending one text message = 
the cost for sending one text message is 0.04.

What is text message?</h3>
- Text messaging, or texting, is the act of composing and sending electronic messages, typically consisting of alphabetic and numeric characters, between two or more users of mobile devices, desktops/laptops, or another type of compatible computer.
- Text messages may be sent over a cellular network, or may also be sent via an Internet connection.
- The term originally referred to messages sent using the Short Message Service (SMS). It has grown beyond alphanumeric text to include multimedia messages using the Multimedia Messaging Service (MMS) containing digital images, videos, and sound content, as well as ideograms known as emoji (happy faces, sad faces, and other icons), and instant messenger applications (usually the term is used when on mobile devices).
