Complete question :
Mathilde has 20 pints of green paint. She uses 2/5 of it to paint a landscape and 3\10 of it while painting a clover. She decides that for her next painting she will need 14 pints of green paint. How much more paint will she need to buy
Answer:
8 pints
Step-by-step explanation:
Initial Pints of green paint = 20
For landscape use:
2/5 * 20 = 40/5 = 8 pints
Painting clover :
3/10 * 20 = 60/10 = 6 pints
Quantity left :
Initial amount - total used
20 - (8 + 6)
20 - 14 = 6 pints
Quantity needed for next painting = 14 pints
Quantity more required :
14 pints - 6 pints =. 8 pints
7/26 x 4/3 x 1/2
= 7 x 4 x 1/26 x 3 x 2
= 28/156
= 0.179
A quadratic equation is an equation of the form ax^2 + bx + c =0.
Given the equation: -2 = -x + x^2 - 4, we write it in the form of a standard quadratic equation as follows:
x^2 - x - 4 + 2 = 0
x^2 - x - 2 = 0
Comparing this with the standard quadratic equation gives that a = 1, b = -1 and c = -2
Therefore, the correct substitution of the values of a, b and c from the given equation into the quadratic formular is: <span>x = [-(-1) + or - sqrt((-1)^2 - 4 x 1 x -2)] / (2 x 1)</span>
Well the rule for bases with multiple exponents is:
((a^b)^c)^d = a^(b*c*d)
So in this case we have:
(((x^(1/3))^4)^5
x^(4*5*1/3)
x^(20/3)
The "transformation" for a base being raised to multiple exponents is to raise the base to the power of the product of all exponents.
Answer:
Step-by-step explanation:
Here, to compute the expected value you only need to multiply each payout value by the correspondently probability and add all the results. More exactly,
Expected value= 1*0.35+2*0.2+5*0.1+8*0.2+10*0.15=4.35
