The slope of the line = 1/2
5/10 is rhe reduced form because 5 goes into both so 25/5=5
And 50/5=10
Answer:
A
Step-by-step explanation:
to solve this problem, we can use the proportion method,
x /40 = 150/1
cross multiply
x (1) = (150)(4)
x = 600
Answer:
Test statistic = - 2.29
Pvalue = 0.0110
Step-by-step explanation:
The hypothesis :
H0 : p = 0.3
H1 : p < 0.3
Test statistic :
z=pˆ−p/√p(1−p)/n
pˆ = 0.2
Z = (0.20 - 0.30) / √(0.30(1 - 0.30) / 110
Z = - 0.1 / √0.0019090
Z = - 0.1 / 0.0436931
Z = - 2.29
Test statistic = -2.29
The Pvalue :
P(Z < -2.29) = 0.0110
Answer:
Step-by-step explanation:
Let x represent the number of miles after which the cost of both options will be the same.
You have two payment options. Option A is to buy a monthly pass for $30 and pay $0.80 per ride. This means that the total amount that you would pay for x miles if you use this option is
0.8x + 30
Option B is to pay $2.30 per ride. This means that the total amount that you would pay for x miles if you use this option is
2.3x
An equation to show after how many rides the cost will be the same would be
0.8x + 30 = 2.3x
2.3x - 0.8x = 30
1.5x = 30
