Answer:
<u>Use Two sided t-test</u>
<u>Step-by-step explanation:</u>
Note that, there are other tools to test for significant difference such as simple regression or multiple regression<em> but when comparing the results of two groups in terms of which is higher or lower</em>, then a two sided t-test would be best appropriate.
Since we want to know if there is a significant difference between the number of tornadoes in August and the number of tornadoes in October on average we use the two sided t-test because a Two sided t-test can show the possibility of positive or negative differences.
Answer:
678.24 in³
Step-by-step explanation:
radius r = 6 in
height h = 6 in
volume V = 678.24 in³
lateral surface area L = 226.08 in²
top surface area T = 113.04 in²
base surface area B = 113.04 in²
total surface area A = 452.16 in²
In Terms of Pi π
volume V = 216 π in³
lateral surface area L = 72 π in²
top surface area T = 36 π in²
base surface area B = 36 π in²
total surface area A = 144 π in²
Agenda: r = radius
h = height
V = volume
L = lateral surface area
T = top surface area
B = base surface area
A = total surface area
π = pi = 3.1415926535898
√ = square root
Calculate volume of a cylinder:
V = πr²h
Oar City because 45/9 = 5 and 27/3 = 9, 5 < 9.
If this is correct please give me Brainliest, thank you!
Answer:
x = 9; This problem is also true because 5x + 45 is equal to 5x + 45
Step-by-step explanation:
First you would distribute 5 into x and 9
5x + 45 = 5x + 45
Then we would divide both 45 on both sides by 5
5x + 45 = 5x + 45
÷5 ÷5
---------------------------
x = 9

Answer: the system of equations are
x + y = 22
x + 1.5y = 30
Step-by-step explanation:
Let x represent the number of math problems that Olivia solved.
Let y represent the number of pages that Olivia read.
Olivia completed a total of 22 math problems and pages of reading. This means that
x + y = 22- - - - - - - - - - - - - - -1
Olivia can solve each math problem in 1 minute and she can read each page in 1.5 minutes. Olivia completed a total of 22 math problems and pages of reading in 30 minutes. This means that
x + 1.5y = 30 - -- - - - - - - - - -2
