Answer:
on the same dot but on the left sid
Step-by-step explanation:
Selling price of boat: 1.3($10,000) = $13,000.
Salesman's commission: 0.25($13000-$10000) = 0.25($3000) = $750
Answer:
That probability is 0.1838 or 18.4% or enter 18.4
Step-by-step explanation:
mean 35 sd 5
20 is 3 sd s to the left of the mean
30 is 1 sd to the left.
The empirical rule has 68% within 1 sd or 34% on one side
It has 95% within 2 sd or 47.5% on one side
It has 99.7% within 3 sd or 49.85% on one side
Therefore between 3 sd and 1 sd on one side is 49.85-34=15.85% or enter 15.9
mean of 48 sd 7
between 48 and 55 is between -1 and 0 sd or 34% enter 34. The last one doesn't seem to post easily:z=(x-mean)/sd or z< (1217-1481)/293 or z <-264/293 or -0.901,
That probability is 0.1838 or 18.4% or enter 18.4
Ratios are proportional if they represent the same relationship. One way to see if two ratios are proportional is to write them as fractions and then reduce them. If the reduced fractions are the same, your ratios are proportional.
Okay, this is a simplified version of how to solve this complicated equation.
First add like terms but in this equation is not very efficient when solving.
So subtract the -2x squared from both sides and the equation should like mine
x⁴ + 4x³ + 12x + 45 = x ² -2x ² + 6x + 9
So keep the left side of the equation the same, but change the right like this because your adding the x squared.
-x² + 6x + 9
Now go back to the whole equation
x⁴ + 4x³ + 12x + 45 = -x² + 6x + 9
You can’t do anything on the left side of the equation do the same process with the other numbers like this:
x⁴ + 4x³ + 12x = -x² + 6x + 9 -45
You subtract the 45 from each side and it’s negative on the other side because you subtracted it.
Now add the 9 and -45 = -36
Now the equation should look like this:
x⁴ + 4x³ + 12x = -x² + 6x -36
Subtract -12x from each side and the 12x on the left side of the equation is canceled out and is gone
The equation should look like this:
x⁴ + 4x³ + = -x² + 6x -36 -12x
Then add the 6x and -12x because they are like terms
So this is the final simplified version of the complex problem
x⁴ + 4x³ + = -x² + -36 -6x
You can’t add any other like terms to find the value of x because x and x² can’t be added together
