Answer: x = 115/2 and 119/6
You can simplify the answer.
Step-by-step explanation:
(2x + 5)(6x -1)= 120
120 = (2x +5) and (6x -1) = 120
120 - 5 = 2x and 6x = 120 - 1
115 = 2x and 6x = 119
115/2 = x and x = 119/6

Answer:
Yes there is sufficient evidence to reject the company's evidence
Step-by-step explanation:
From the question we are told that
The sample size is n = 25
The mean is
The standard deviation is 
The z-score is z = -1.94
The null hypothesis is 
The alternative hypothesis is 
Generally the p-value is mathematically evaluated as

From the z table the area under the normal curve to the left corresponding to -1.94 is

=> 
=> 
Let assume the level of significance is 
Hence the
this mean that
The decision rule is
Fail to reject the null hypothesis
The conclusion is
There is sufficient evidence to reject the company's evidence
Answer:
500
Step-by-step explanation:
Given: P = 150 - T where P is passenger cars and T is trucks
10P = 7T ⇔ P = 
Plug in equation 2 into equation 1:
= 150 - T
Solving for T, we get 500
