Let X be the random variable denoting the number of girls that are born. Then X has a binomial distribution on n=125 babies and probability of getting a girl p=0.5. The probability we want is

\mathbb P(X\ge60)=\displaystyle\sum_{x=60}^{125}\binom{125}x0.5^{125-x}0.5^x\approx0.704=70.4\%

alice planted 6 tomato plants 4 bean plants and 2 pepper plant. each row had 6 plants. how many rows did she plant
ANTONII [103]
First, add the number of plants.

6+4+2= 12 plants in total

There can be 6 plants in each row so divide 12 by 6 to get the number of rows used to plant 12 plants.

12/6=2

The answer is 2 rows.

X^2=1 has two solutions. If the equation is changed to 4x^2=1 which operation find the solutions of the new equation?
snow_lady [41]

Answer:

X = -1/2 or 1/2

Step-by-step explanation:

When the square root of  a number is found, this usually results in 2 solutions which may be equal in size but opposite in signs.

As such,

X^2=1 to find x find the root of both sides

X = √1

X = -1 or 1

Going by this

4x^2=1

Divide both sides by 4

X^2=1 /4

taking the square root of both sides

X = √1/4

The root of 1 is -1 or 1 while that of 4 is -2 or 2 hence,

X = -1/2 or 1/2
