Answer: B. 135/364
In solving this kind of probability problems, we have to use the Hyper geometric Probability without replacement. We are given with two groups which would be the source of the 4 members of the new group, 2 coming from each respective group.
Equation:
P = [(pCr)(qCm)]/(sCt)
= [(10C2)(6C2)]/(16C4)
= 135/364
Distributive property. You distribute the 2 to the X and get 2x, then distribute the 2 and the 3. 2X3=6. This gets you 2x+6.
635/72=-5/2(-11/4+x)
distribute
635/72 = -5/2 * -11/4 - 5/2x
635/72 = 55/8 -5/2 x
multiply each side by 72 to clear the fractions
72*635/72 = 72*(55/8 - 5/2 x)
distribute
635 = 72* 55/8 - 72* 5/2 x
635 = 495 - 180x
subtract 495 from each side
140 = -180 x
divide by -180
-140/180 = x
-14/18 =x
-7/9 =x
Answer:
13%
Step-by-step explanation:
we can find the percentage by dividing 5 by 37 1/2
5/37.5=0.1333333... or about 13%
