Answer:

C. \frac{1}{4}

Step-by-step explanation:

Step 1: find the probability to satisfy the first roll

There are 3 odd numbers on the dice, so there's a 3/6 or 1/2 chance of rolling an odd number on the first roll.

Step 2: find the probability to satisfy the second roll

There are 3 even numbers on the dice, so there's a 3/6 or 1/2 chance of rolling an even number on the second roll.

Step 3: multiply the probabilities to get a compound inequality

\frac{1}{2} *\frac{1}{2} =\frac{1}{4}

So... choice C? I suppose?

I NNEEEDDDDDD HELPPPPP PLEASEEEE
NikAS [45]

Answer:

The small balloon bouquet uses  7 balloons and the large one uses

18 balloons.

Step-by-step explanation:

Let's say that small balloon bouquets are S and large balloon bouquets are L. For the graduation party the employee assembled 6 small bouquets and 6 large bouquets, the total number of balloon used is 150. To put the sentence into an equation will be:

6S + 6L= 150

S+L= 25   ----> 1st equation

For Father's Day, the employee uses 6 small bouquet and 1 large bouquet, the total number of balloons used is 60. The equation will be:

6S + 1L= 60

1L= 60- 6S   ----> 2nd equation

We can solve the number of small balloon bouquet by substitute the 2nd equation into 1st. The calculation will be:

S+L = 25

S+ (60-6S)= 25

-5S= 25-60

-5S= -35

S= -35/-5

S=7

Then we can find L by substitute S value to 1st or 2nd equation.

S+L=25

7+L=25

L=18

Hope this helps ;)

Round to the nearest hundreds place<br> Show your work<br> 4x = 7 - 8x - 27
faltersainse [42]

Answer:

x = 5

Step-by-step explanation:

4x = 7 - 8x - 27

1) Combine like terms (7 and -27). So, 7 + (-27) = -20.

        4x = 8x - 20

2) Subtract 8x from both sides of the equation. So, 4x - 8x = -4x.

        -4x = -20

3) Divide both sides by -4. So, -20 / -4 = 5.

        x = 5
