Answer:
y = -7x - 5
Step-by-step explanation:
14x + 2y = -10
2y = -14x - 10
2y/2 = -14x/2 - 10/2
y = -7x - 5
Hope this helps -w-
The actual probability of having odd is 3/6=1/2
so no of odds theoretically is 250
but it is 325
so, experimental is higher than theoretical
so answer is B !
and you can go for that !
<span>We can safely assume that 1212 is a misprint and the number of seats in a row exceeds the number of rows by 12.
Let r = # of rows and s = # of seats in a row.
Then, the total # of seats is T = r x s = r x ( r + 12), since s is 12 more than the # of rows.
Then
r x (r + 12) = 1564
or
r**2 + 12*r - 1564 = 0, which is a quadratic equation.
The general solution of a quadratic equation is:
x = (-b +or- square-root( b**2 - 4ac))/2a
In our case, a = 1, b = +12 and c = -1564, so
x = (-12 +or- square-root( 12*12 - 4*1*(-1564) ) ) / 2*1
= (-12 +or- square-root( 144 + 6256 ) ) / 2
= (-12 +or- square-root( 6400 ) ) / 2
= (-12 +or- 80) / 2
= 34 or - 46
We ignore -46 since negative rows are not possible, and have:
rows = 34
and
seats per row = 34 + 12 = 46
as a check 34 x 46 = 1564 = total seats</span>
V= LWH so 3.75cm^3 or 3 (3/4)
Multiply those three sides and it comes out to 3.75
Answer:
