It would be true for all values of x. If you multiply out the right hand side, you would get -3x = -3x. Dividing both sides by -3 gives you x=x, which is always true.

Hope this helps!

With a capacity of 6,300 people, Royal Caribbean’s Oasis of the Seas is the world’s largest cruise ship. The average beer consum
Mariulka [41]

Step-by-step explanation:

Mean = 81740

Standard deviation = 4590

Sample size = 15

Alpha level = 1-0.95 = 0.05

Df = 15-1 = 14

Critical value:

alpha/2 = 0.05/2 = 0.05

t0.025

t critical value = 2.145

Margin of error ME

2.145 x 4590/√15

2.145 x 4590/3.873

ME = 2542.09

Confidence interval

Lower CI = mean - ME

= 81740-2542.09

= 79197.91

Upper CI = mean + ME

= 81740+2542.09

= 84282.09

[ 79197.91, 84282.09]

B.

Using excel, exact answer for CI

Lower limit = 79198.142724212173

Upper limit = 84281.8572757827

C.

The assumptions to be made from the population are that

1. Samples are random

2. These samples are gotten from an approximately normal distribution

Cylinder A has a radius of 7 inches and a height of 5 inches. Cylinder B has a volume of 490π. What is the percentage change in
Maru [420]

The percentage change in volume from cylinder A to cylinder B; D: 100%

<h3>How to find the percentage change in Volume?</h3>

Formula for Volume of a Cylinder is;

V = πr²h

Thus, volume of Cylinder A is;

V_a = π * 7² * 5

V_a = 245π

Thus, percentage change in volume is;

[245π/(490π - 490π)] * 100%

Percentage change in volume = 100%

Katyanochek1 [597]

Step 1: Find X

3x + 7 + 9x + 17

Add the alike terms: 12x + 24

Linear is 180 degree, 12x + 24 = 180; now find x

X = 13

Now find the degree for both.

RST: 3 (13) + 7 = 46

VST: 9 (13) + 17 = 134

You're answer is A
