<u>Answer</u>
1.72 or -0.387
<u>Explanation</u>
3x²-4x-2=0
3x²-4x = 2
x² - (4/3)x = 2/3
x² - (4/3)x + (2/3)² = 2/3 + 4/9
(x - 2/3)² = 10/9
x - 2/3 = √10/3 or x - 2/3 = -√10/3
x = √10/3 + 2/3 or x = -√10/3 + 2/3
= 1.72 or = -0.387

Answer:
There is no scatter plot provided, but I can tell you how to solve this. You will look at the plot. It should be numbered somewhere 0-10 and tell you that is the point system, the other side should be the students. So, now you will look at the points on the plot and determine where most of them are. If they are low, you would say that she thinks that they are bad. If it's mostly middle, you would say they need improvement, but aren't terrible. If they are high, you would say she thinks that they are very good.
I'm not really sure but I think it's 3.39
2/3 of a pizza is more than half of the pizza.
3/6 = 1/2, so 3/6 of a pizza is exactly half of the pizza.
Given that two pizzas are of different sizes you need to calculate the areas of each pizza and compare them.
Assumming that the two pizzas are circular, you can calculate the area of each pizza from the formula of the area for a circle:
Area of a circle = π * (radius)^2.
Call r the radius of Jake's pizza and R the radius of Al's pizza. Then:
Area of Jake's pizza = π (r^2) and 2/3 of that is: 2π(r^2) / 3.
Area of Al's pizza = π (R^2) and 1/2 of that is π(R^2)/2
So, what you have to do is to use the radius of each pizza, calculate above formulaes and verify whether the results are the same or not.
