Sloan [31]3 years ago

Total amount of students = 6

Total amount of girls = 4

So, chance of picking a girl first time is 4/6 or 2/3 chance

But remember! The girl is picked, and we do not want to replace her back into the set. So total amount of students drop to 5 and girls drop to 3

So using that logic, The probability of choosing all girls = 4/6 * 3/5 * 2/4 * 1/3 = 1/15.

Oceanside Bike Rental Shop charges 13 dollars plus 9 dollars an
enyata [817]

In this question, we're trying to find how many hours Mike had the bike for.

We know that 13 dollars as a flat rate.

We also know that they charge 13 dollars and hour.

Mike paid a total of 67 dollars for the bike.

Lets represent this as an equation:

67 = 9x + 13

x = hours the bike was rented

Solve for x:

67 = 9x + 13

Subtract 13 from both sides

54 = 9x

Divide both sides by 9

6 = x

This means that Mike rented the bike for 6 hours.

Answer:

6 hours

Answer:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
x-(3*x^3+8*x^2+5*x-7)=0
Step by step solution :Step 1 :Equation at the end of step 1 : x-((((3•(x3))+23x2)+5x)-7) = 0 Step 2 :Equation at the end of step 2 : x - (((3x3 + 23x2) + 5x) - 7) = 0 Step 3 :Step 4 :Pulling out like terms :
4.1 Pull out like factors :
-3x3 - 8x2 - 4x + 7 =
-1 • (3x3 + 8x2 + 4x - 7)
Checking for a perfect cube :
4.2 3x3 + 8x2 + 4x - 7 is not a perfect cube
Trying to factor by pulling out :
4.3 Factoring: 3x3 + 8x2 + 4x - 7
Thoughtfully split the expression at hand into groups, each group having two terms :
Group 1: 3x3 - 7
Group 2: 8x2 + 4x
Pull out from each group separately :
Group 1: (3x3 - 7) • (1)
Group 2: (2x + 1) • (4x)

Please 5 star and like. Appreciated

igomit [66]

Answer:

State C : $30.9 Million       State D : $25.7 Million

Step-by-step explanation:

It may help to just forget about the word "million" and focus on the decimal number part,so one you get the deciaml number you can just put the word million after it as your answer.

First do 56.6 divided by 2, which equals 28.3. Since it said that State C spends 2.6 million more, you hvae to add 28.3 and 2.6 together, which also equals 30.9. So now you know State C spends $30.9 million total. In order to find out how much money State D sends, you have to do 56.6 - 30.9,which comes up to 25.7. So finnaly you know that State C spends 30.9 million dollars and State D spends 25.7 million dollars.
