Answer:

D.) 0.9990

Step-by-step explanation:

Given :

Number of questions = 10

True or False questions ; probability of success, p = 1/2 = 0.5

P(x =x) = nCx * p^x * (1 - p)^(n - x)

Probability of getting atleast one correct answer :

P(x ≥ 1) = p(1) + p(2) +... P(x = 10)

Using a binomial probability calculator :

P(x ≥ 1) = 0.9990

If given the opportunity to interview Walt Disney for 30 minutes I would ask him what made him want to go into the entertainment business and what was his inspiration.
First of all, I would ask him what made him want to go into the entertainment business because Walt Disney has been known to have been a very intelligent and hard working individual, so why not put such great skills the rest and get a better job?
Finally, I would also ask him what his inspiration was because Walt Disney has helped to create and make so many wonderful characters and movies that have brought joy to many; who wouldn't want to know what inspired him to create such wonderful things.

Mark and Julio are selling flower bulbs for a school fundraiser. Customers can buy bags of windflower bulbs and packages of croc
ikadub [295]

Answer:

Bag of windflower bulbs costs $8.50

Package of crocus bulbs costs $17.60

Step-by-step explanation:

Let $x be the price of one bag of windflower bulbs and $y be the price of one  package of crocus bulbs.

1. Mark sold 2 bags of windflower bulbs for $2x and 5 packages of crocus bulbs for $5y. In total he earned $(2x+5y) that is $105. So,

2x+5y=105

2. Julio sold 9 bags of windflower bulbs for $9x and 5 packages of crocus bulbs for $5y. In total he earned $(9x+5y) that is $164.50. So,

9x+5y=164.50

3. You get the system of two equations:

\left\{\begin{array}{l}2x+5y=105\\ \\9x+5y=164.50\end{array}\right.

From the first equation

5y=105-2x

Substitute it into the second equation:

9x+105-2x=164.50

7x=164.50-105

7x=59.5

x=$8.50

So,

5y=105-2·8.5

5y=105-17

5y=88

y=$17.60
