Answer:
65 degrees
Step-by-step explanation:
85 + 30 = 115
180 - 115 = 65
Verify:
a + b + c = 180
85 + 30 + 65 = 180
180 = 180
Answer:
y=x-3
Step-by-step explanation:
slope=4+2/-5-1=-1
perpendicular slope= negative reciprical=1
y=x+b
midpoint on perpendicular bisector= (-5+1/2, 4-2/2)=(-2,1)
substitution-2=1+b, b=-3
y=x-3
Answer:
Irrational numbers

They Cant be an integer, because they are not on the common numberline of positive and negative numbers.
Answer:
Option C) The average contents of all bottles of juice in the population, which is 473 mL
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 473 mL
Sample mean,
= 472 mL
Sample size, n = 30
Sample standard deviation, σ = 0.2
First, we design the null and the alternate hypothesis
Representation of 
is the population parameter that represents the population mean.
Thus, for the given situation
represents:
Option C) The average contents of all bottles of juice in the population, which is 473 mL
