Answer:
Point X is 10 units above Point Y or (X,Y-10)=Y
Step-by-step explanation:
A quadratic equation has the general formula
expressed as:<span>
ax^2 + bx - c = 0
This equation can be solved by the quadratic
formula which is expressed as:
x = ( -b (+ or -) √(b^2 - 4ac) / 2a
From the given equation, </span><span> y=-0.005x^2+0.41x-5.1
</span><span>
a = -0.005
b = 0.41
c = -5.1
Using the quadratic formula and the corresponding values of the coefficient, we substitute these and obtain:
</span>x = ( -b (+ or -) √(b^2 - 4ac) / 2a
x = ( -0.41 (+ or -) √(0.41^2 - 4(-0.005)(5.1)) / 2(-0.005)
x1 =66.71
x2 = 15.29
Therefore, the quadratic equation would be factored by using the values of x we obtained as follows:
<span>y= -0.005x^2 + 0.41x - 5.1
</span>y = (x - 66.71) ( x - 15.29 )
The answer is B: The distribution for town A is symmetric, but the distribution of town B is positively skewed.
Answer:
3.5 Oz of chocolate
Step-by-step explanation:
1.6 lb of cookie dough is made from chocolate of 8 Oz
1 lb will be made by 8/ 1.6 = 0.5 Oz of chocolate
Therefore
7lb of cookie dough will be made from 7 * 0.5= 3.5 Oz of chocolate/
