Answer:
Any point on the line.
Step-by-step explanation:
x+6=0 is a straight line, and this line is infinite. You can pick three points on the line and the middle point is the vertex. This vertex can be any point on the line because there are an infinite amount of points to choose.
Brother's weight * 5/8 = 110
Brother's weight * 5/8÷5/8 = 110÷ 5/8
Brother's weight = 176

Explanation:</h2>
As I understand the expression is the following:
Let's call, that expression as 
So we are asked to find the value of the expression when . In other words, we need to substitute , so:

Answer:
Step-by-step explanation:
H0 : μ = 46300
H1 : μ > 46300
α = 0.05
df = n - 1 = 45 - 1 = 44
Critical value for a one tailed t-test(since population standard deviation is not given).
Tcritical = 1.30
The test statistic :(xbar - μ) ÷ (s/sqrt(n))
The test statistic, t= (47800-46300) ÷ (5600√45)
t = 1500
t = 1500 / 834.79871
t = 1.797
The decision region :
Reject H0: if t value > critical value
1. 797 > 1.30
Tvalue > critical value ; We reject H0
Hence, there is sufficient evidence to conclude that cost has increased.
