Answer: 8.1%
Step-by-step explanation:
Given : 
Let x be the random variable that represents the actual speeds of cars.
The speed limit on a road is 60 mph.
Using formula , 
, we have for x= 60+10=70
Using z-table for right-tailed test value, The probability of cars exceed the speed limit by more than 10 mph will be
Hence, the percentage of cars exceed the speed limit by more than 10 mph is 8.1%.
Answer:
4.2 team members per day
Step-by-step explanation:
5 + 4 + 2 + 7 + 3 = 21
21/5 = 4.2
1.78 is the correct answer.
Answer:
Question 1. (2.2, -1.4)
Question 2. (1.33, 1)
Step-by-step explanation:
Equations for the given lines are
-----(1)
It is given that this line passes through two points (0, 2.5) and (2.2, 1.4).
------(2)
This equation passes through (0, -3) and (2.2, -1.4).
Now we have to find a common point through which these lines pass or solution of these equations.
From equations (1) and (2),
x =
x = 2.2
From equation (2),
y = -1.4
Therefore, solution of these equations is (2.2, -1.4).
Question 2.
The given equations are y = 1.5x - 1 and y = 1
From these equations,
1 = 1.5x - 1
1.5x = 2
x =
Therefore, the solution of the system of linear equations is (1.33, 1).
