Answer: They are proportional.
Explanation: To determine whether a table is proportional just simply notice if there is a number you can get to the next number.
Example: on the x values you multiply from left to right by 2 and get the next number. on the y values you multiply by 1. This table is proportional

Answer:
irrational
Step-by-step explanation:
If we assume the decimal fraction continues indefinitely without repeating, then the number is <em>irrational</em>.
__
The pattern that seems to have been established is an increasing number of repetitions of the digit 3, with each set followed by the digit 2. This pattern can continue indefinitely without repeating.
Answer:
(230.21 ; 233.13)
Step-by-step explanation:
Given the data :
230.66, 233.05, 232.58, 229.48, 232.58
To calculate the 90% CI
WE obtain the mean and standard deviation of the sample data :
Mean of sample, ΣX /n = 1158.35/5 = 231.67
The standard deviation of the sample, s = 1.531 (Using calculator).
(The 90% Tcritical value, 2 sided, df = 4) = 2.132
The confidence interval, CI :
Mean ± Tcritical * s/√n
C.I = 231.67 ± (2.132 * (1.531/√5)
C. I = 231.67 ± 1.4597
(231.67 - 1.4597) ; (231.67 + 1.4597)
(230.21 ; 233.13)
Answer:
The Answer is: x = 29
Step-by-step explanation:
Put all of the angles equal to 360 degrees:
(5x - 8) + (3x + 4) + 89 + 51 = 360
Collect like terms and solve for x:
5x + 3x - 8 + 4 + 89 + 51 = 360
8x - 4 + 140 = 360
8x + 136 = 360
8x = 224
x = 224/8 = 28

Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 6, 8) and (x₂, y₂ ) = (- 6, - 5)
m = 
= 
division by zero is undefined, hence slope is undefined
