A parabola is defined by the equation x2 = 3/4 y. In which direction will the parabola open?

TEA [102]

The equation of parabola is $x^2=\dfrac{3}{4}y$ .
The canonical equation of parabola is $y^2=2p x$ and this parabola has branches that go in positive direction of x-axis.

Since in your equation x is changed to y and y to x, then the <span>branches of the parabola go in positive y-axis direction, the vertex is placed at the origin.

An ordinary (fair) coin is tossed 3 times. Outcomes are thus triples of "heads" (An ordinary (fair) coin is tossed 3 times. Ou)

Answer:

Probability distribution

X P(X)

0 1/8

1 3/8

2 3/8

3 1/8

Step-by-step explanation:

When a coin is tossed there are two outcomes head and tail. When three coins are tossed the possible outcomes are

Sample space=S={HTH,THH,TTH,HHH,HTT,THT,TTT,HHT}

The total number of outcomes is n(S)=8. The X be the random variable counting number of tails in each outcome and so X can take values as 0,1,2,3. The probabilities can be computed as P(X)=n(X)/n(S). The probabilities are calculated as under:

X Outcomes P(X)

0 HHH 1/8

1 HHT,THH,HTH 3/8

2 TTH,HTT,THT 3/8

3 TTT 1/8

The probability distribution of X is as under:

X P(X)

0 1/8

1 3/8

2 3/8

3 1/8
