-2m+15=45
-2m=45-15

-2m + 15 = 45 (original problem)
-2m = 30          (remove 15 from both sides)
-2m/-2 = 30/-2 (divide by -2)
m = -15

Henry has two pixie sticks full of delicious sugar. Henry
Sholpan [36]

Answer:

14.67 gram

Step-by-step explanation:

Henry has two pixie sticks full of delicious sugar.

Now, each pixie stick contains 22 grams of sugary goodness, then in two sticks, there will be (22 × 2) = 44 grams of sugar.

Now, Henry shares two pixie sticks among two friends and himself in equal proportion.  

Therefore, each of his friends will get \frac{44}{3} = 14.67 (Round to the nearest tenth) gram of sugary goodness. (Answer)

Find the probability of exactly three successes in six trials of a binomial experiment in which the the probability of is 50%.
Lyrx [107]

Start by doing the binomial expansion of (x+y)^6 where x represents success. This is

(x^6y^0) + 6(x^5y^1) +15(x^4y^2) +20(x^3y^3) +15(x^2y^4) +6(x^1y^5) +(x^0y^6)

We are interested in the x^3y^3 term which represents exactly 3 sucesses. Since the probalbility of sucess and failure are both .5 we should be able to figure this out just using the coefficients of the terms which is

20/64 = .3125 which is 31.25%
