You flip 3 coins. What is the probability that you get exactly 2 heads?

1 answer:

5 0

The probability of one head must be 3/8. I believe there is a 50% chance of getting a toss of more then 1 head in 3 tosses.

Three consecutive odd integers are such that the sum of the first and second is 31 less than 3 times the third. Find the integer

Otrada [13]

1st:x

2nd x+2

3rd: x+4

(x)+(x+2) = 3(x+4)-31

distribute

2x+2 = 3x+12-31

2x+2 =3x-19

subtract 2x from each side

2 = x-19

add 19 to each side

21 =x

[ please help! ] The graph below shows a line segment PQ.

Tpy6a [65]

Answer:

Slope of the line segment PQ is 1/2.

Step-by-step explanation:

We are given with a line connecting two points P and Q.

The coordinates of P are (4,4) and the coordinates of Q are (-2,1).

Slope of line joining two points $(x_{1},y_{1})$ and $(x_{2},y_{2})$

is given by the formula $\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$

Hence the slope of the line PQ is $\frac{1-4}{-2-4}=\frac{-3}{-6}= \frac{1}{2}$

Therefore correct option is 'C' that is 1/2.
