Answer:
5x^2 - 4x - 3 = 0
Step-by-step explanation:
For the equation
ax^2 + bx + c = 0
the roots are [-b +/- √(b^2 - 4ac)] / 2a
So comparing the terms to the values in the question:
a = 5
b = -4
c = -3
Answer:
0.60, 2/3, 70%, 3/4, .85
Step-by-step explanation:
<span>The measure standard deviation quantifies the amount of variation or dispersion of a set of data values.</span>The standard deviation is the square root of the variance.
The standard deviation in this case is 50/ sqrt(100)= 50/10=5.
It is 36 feet
A=1/2bh
a=1/2*12*6
a=6*6
a=36feet squared
hope this helps!
