Answer:
The correct answers are as follows.
a. 8.624%
b. 60.84%
c. 27.75%
Step-by-step explanation:
In order to find each of these, take the likelihood of each of steps and multiply them together.
a. For this one, we need to note that the first two spins should not be blue. The likelihood of them not being blue is the chance for red and green put together (37%). Then we want the third spin to be the blue odds (63%)
.37 * .37 * .63 = .08624 = 8.624%
b. For the purpose of this, we are looking just for the first two spins to not be red (78% probability). After that, it does not matter what the third spin is since it says "at least 3 times)
.78 * .78 = .6084 = 60.84%
c. For this one, we need to combine two things. Firstly, the chance that the first spin is green (15%). Then we would add in the likelihood that the first spin is not green (85%), but the second is.
.15 + (.85 * .15) = .2775 = 27.75%
Answer:
The amusement park needs to pay at least $98.40 to 225 employees. So the minimum price they need to charge to pay all the employees is 98.40 x 225
Step-by-step explanation:
Profit minimum= employee pay x employee amount
98.40 x 225
After multiplication, profit minimum needs to be= $22140
Divide profit minimum by guests to get price per ticket
22140/1000 guests
$22.14= price of ticket for minimum profit
Answer:
149
Step-by-step explanation:
If you order the numbers from smallest to biggest and then find the middle number it is 149
It is a quadratic
where x-8 is the squared term
do
x-8=u
u^2-13u+30=0
solve
u=
u=
u=
u=
u=
u=
or u=
u=10 or 3
10=x-8 or 3=x-8
18=x or 11=x
x=11 and/or 18
