Answer:
1) x = 0, x = 1
2) x = -0.387 , x = 1.721
Step-by-step explanation:
3x² - 3x + 2 = 2
To convert this into the given graph, subtract 3 from both sides, you get
3x² - 3x - 1 = -1
You can find the x values for y = -1 to solve the given equation.
At y = -1, x = 0, 1
3x² - 3x - 1 = x + 1
To solve for this, add a straight line y = x + 1 on the same graph and look for the point of intersections
You'll see the line and the graph meet at two points:
x = -0.387 and x = 1.721
Answer:
<u><em>8,126,500</em></u>
Step-by-step explanation:
Use order of operations and deal with the multiplication first
(81265 * 169) - (81265 * 69)
13,733,785 - 5,607,285
<u><em>8,126,500</em></u>
Answer:
The proportion of trees greater than 5 inches is expected to be 0.25 of the total amount of trees.
Step-by-step explanation:
In this problem we have a normal ditribution with mean of 4.0 in and standard deviation of 1.5 in.
The proportion of the trees that are expected to have diameters greater than 5 inches is equal to the probability of having a tree greater than 5 inches.
We can calculate the z value for x=5 in and then look up in a standard normal distribution table the probability of z.
The proportion of trees greater than 5 inches is expected to be 0.25 of the total amount of trees.
So in order for us to come up with the right equation, let us analyze the given problem first.
So the total number of people on the trip is 82.
The number of children under 12 is 54. Which makes the number of people over 12 is 28.
The number of children under 3 is x.
And c <span>represents the total amount of money collected from tickets that day.
</span>So based on this, we can say that the equation would be:
C = 28(44) + (54-x)32

Answer:
10
Step-by-step explanation:
I got you Gang (insert random gang signs that mean respect or something)
to find the area of a 2dimensional rectangle
we must use the formula
l × h = area
pretend that (5) means the square root of 5
(5) × 2(5) = 2(25)
simplify (25) = 5
2 × 5 = 10
