I'm not sure what to do for the "arithmetic approach" but for the algebraic approach:
The equation you need to solve would be 5.35x + 182.90 = 750
when you solve it, you would get x = 106, meaning they would have to sell 106 more
Answer:
4
Step-by-step explanation:
2x+y=12
y=-2x+12
y-2=3(x-2)
If it’s parallel to each other: the slope has to be the same.
If is perpendicular to each other: the slope should be the reciprocal to each other.
The first equation has a slope of -2
The second has a slope of 3
Neither the condition meet. So the answer is 4
Answer:
X= -11/6. Y=-40/9
Step-by-step explanation:
Answer:
The probability is 
Step-by-step explanation:
From the question we are given that
The population mean is 
The standard deviation is 
The random number 
The sample size is 
The probability that the sample mean would be greater than 
Generally the z- score of this normal distribution is mathematically represented as

Now

substituting values


Which implies that


Now from the z-table the probability is found to be
