A locker requires a three-digit code to open the lock. The code must contain one letter and two numbers, and no letter or number

mixas84 [53]

A locker requires a three-digit code to open the lock. The code must contain one letter and two numbers, and no letter or number can be repeated. You can choose from among four letters, A, B, C, and D, and two numbers, 5 and 6.

The size of the sample space is: (8, 16, 20, 24)

If a code is chosen at random, the probability that it has a letter that immediately follows an odd number is: (1/8, 1/6, 1/3, 2/5, 2/3)

If a code is chosen at random, the probability that D is in the code but is not in the first position is: (1/8, 1/6, 1/3, 2/5, 2/3)

How I do this? 3x+4y=11 X-2y=-3

Amanda [17]

Answer:

$\huge\boxed{x=1,\ y=2\to(1,\ 2)}$

Step-by-step explanation:

$\left\{\begin{array}{ccc}3x+4y=11\\x-2y=-3&\text{multiply both sides by (-3)}\end{array}\right\\\\\underline{+\left\{\begin{array}{ccc}3x+4y=11\\-3x+6y=9\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad\ \ \ \ 10y=20\qquad\text{divide both sides by 10}\\.\qquad\qquad\boxed{y=2}\\\\\text{subtitute it to the second equation:}\\x-2(2)=-3\\x-4=-3\qquad\text{add 4 to both sides}\\\boxed{x=1}$

Ad libitum [116K]

Answer: 1/3^4 or 1 over 3 fourths beacuse you need to just flip it to get the exponent to be positive. 3^-4 is basically 3^-4 over 1.

Alicia is making cupcakes for a party she is having and wants to make sure everyone gets at least one cupcake. The recipe calls

Liula [17]

$\frac{84}{21}=4$

Therefore you need 4 batches of cupcakes if you want every person to get one cupcake.

This means you multiply the amount of salt per batch by the number of batches, to get the total amount of salt you need.
Each batch contains 1 teaspoon of salt for 21 cupcakes. Multiply: $4\text{ batches of cupcakes}\times1\text{ teaspoon of salt}=4\text{ teaspoons salt}$ for the whole thing.
